Answers

Answer 1

Jacquelyn added the numbers 249 and 3922 to obtain a sum of 4171.

To determine which equation represents the sum of the two numbers that Jacquelyn added, we need to find the equation that results in a sum of 4171.

Let's evaluate each equation:

1. 248 + 3922 = 4170

2. 249 + 3922 = 4171

3. 259 + 3922 = 4181

Out of the three equations, only the second equation, 249 + 3922, results in a sum of 4171. Therefore, the correct equation is:

249 + 3922 = 4171

Thus, Jacquelyn added the numbers 249 and 3922 to obtain a sum of 4171.

Work out an approximate solution to x3 + 2x – 1 = 0


Use the iteration Xn+ 1 =


1


x + 2


Start with Xy = 1


Give your answer to 2 decimal places.

Answers

Answer:

x = 0.45 (2 d.p.)

Step-by-step explanation:

Iteration is a numerical method used to approximate solutions to equations where exact solutions are difficult or impossible to obtain analytically.

It involves putting an approximate value of the solution into an iteration formula to calculate a new value based on the previous one. This process is repeated multiple times, with each iteration generating a more accurate approximation of the solution.

The iteration formula is just a rearrangement of the equation, leaving a single ‘x’ on one side.

For this problem, we have already been given the iteration formula and the starting value of x₁. However, sometimes you will need to determine the iteration formula. For example, to determine the iteration formula for x³ + 2x - 1 = 0, rearrange the equation as follows:

[tex]\begin{aligned}x^3+2x-1&=0\\x^3+2x&=1\\x(x^2+2)&=1\\x&=\dfrac{1}{x^2+2}\end{aligned}[/tex]

Therefore, the iteration formula is:

[tex]\boxed{x_{n+1}=\dfrac{1}{{x_n}^2+2}}[/tex]

To calculate the approximate solution to x³ + 2x - 1 = 0 using the given iteration formula, start by substituting  x₁ = 1 into the formula to find x₂:

[tex]x_2=\dfrac{1}{x_{1}{^2}+2}=\dfrac{1}{(1)^2+2}=\dfrac{1}{1+2}=\dfrac{1}{3}=0.3333...[/tex]

Substitute the found value of x₂ into the formula to find the value of x₃:

[tex]x_3=\dfrac{1}{x_{2}{^2}+2}=\dfrac{1}{\left(\frac{1}{3}\right)^2+2}=\dfrac{1}{\frac{1}{9}+2}=\dfrac{1}{\frac{19}{9}}=\dfrac{9}{19}=0.47368...[/tex]

Continue this way until the solutions are the same when rounded to 2 d.p:

[tex]x_4=0.44956...[/tex]

[tex]x_5=0.45411...[/tex]

[tex]x_6=0.45326...[/tex]

[tex]x_7=0.45342...[/tex]

[tex]x_8=0.45339...[/tex]

[tex]x_9=0.45339...[/tex]

Therefore, the approximate solution to x³ + 2x - 1 = 0 is 0.45, rounded to 2 decimal places.

Additional information

The quickest way to compute each solution (each value in the iteration sequence) is to enter the value of x₁ into the calculator and press "=" so that the value of x₁ becomes the "answer". Then type the iteration formula into the calculator, replacing xₙ with "answer":

[tex]\boxed{\dfrac{1}{\text{Ans}^2+2}}[/tex]

Each time you press "=", the next value of xₙ in the sequence is computed.

The range of values that is most likely to include the true population parameter is known as the margin of error. The standard error, a gauge of the sample statistic's variability, is used to determine the margin of error.

Option A in this situation has the most margin of error of the four, at 24%. In comparison to the other options, this indicates that the true population parameter is probably within 24% of the sample statistic. This implies that option A's sample size is smaller than that of the other options.

Therefore, the estimate at a 95% confidence level that most likely comes from a small sample is 93% (±24%).

Answers

The explicit formula for the given sequence 4, -12, 36, -108,... is D. tn = 4(-3)n. Option D

In the given sequence, each term is obtained by multiplying the previous term by -3. This indicates an exponential decay pattern with a common ratio of -3.

To derive the explicit formula, we start with the initial term 4 and observe that each subsequent term can be obtained by multiplying the previous term by -3:

Term 1: 4

Term 2: -3 × 4 = -12

Term 3: -3 ×(-12) = 36

Term 4: -3 × 36 = -108

We can generalize this pattern by using the formula tn = ar^(n-1), where tn represents the nth term, a is the initial term, and r is the common ratio. In this case, a = 4 and r = -3. Thus, the explicit formula for the sequence is tn = 4(-3)n which matches option D.

The area of a triangular garden can be no more than 160 square feet. The base of the triangle is 12 feet. What is the height of the triangle?

Answers

The height of the triangle is approximately 26.67 feet. To find the height of a triangle, we can use the formula for the area of a triangle:

Area = (1/2) * base * height

In this case, we know that the area of the triangular garden can be no more than 160 square feet, and the base of the triangle is 12 feet. We can substitute these values into the formula and solve for the height.

160 = (1/2) * 12 * height

Multiplying both sides of the equation by 2:

320 = 12 * height

Dividing both sides of the equation by 12:

height = 320 / 12

height ≈ 26.67 feet

Therefore, the height of the triangle is approximately 26.67 feet.

You are about to sell your house for For Sale By Owner. Suppose you need to allow for 3% commission for the buyers realtor, and you need to receive a minimum amount of $92,500 on the sale. What is the minimum amount you can list the house for to accommodate both of those requirement?

Answers

To accommodate the 3% commission for the buyer's realtor and receive a minimum amount of $92,500 on the sale, the minimum amount to list the house for would be $95,361. It accounts for the commission and ensures the desired minimum amount is $95,275.

To calculate the minimum amount to list the house for, we need to consider the commission for the buyer's realtor and the desired minimum amount after the commission is deducted.

Step 1: Calculate the commission amount.

The commission for the buyer's realtor is 3% of the sale price. To find the commission amount, we multiply the desired minimum amount by 3% (or 0.03):

Commission = $92,500 * 0.03 = $2,775.

Step 2: Determine the minimum sale price.

The minimum sale price is the desired minimum amount plus the commission amount:

Minimum Sale Price = $92,500 + $2,775 = $95,275.

Therefore, the minimum amount to list the house for would be $95,275. This ensures that after deducting the 3% commission for the buyer's realtor, the seller would receive the desired minimum amount of $92,500.

The Fundamental Counting Principle can be used in situations where there are multiple independent choices or options, and the total number of outcomes needs to be determined.

The Fundamental Counting Principle is a combinatorial principle used to calculate the total number of outcomes or possibilities when there are multiple independent choices or options available.

It states that if there are n choices for one event and m choices for another event, then the total number of outcomes is obtained by multiplying the number of choices for each event.

Based on this principle, the situations in which the Fundamental Counting Principle can be used are:

An employee has sick days and personal days: If the employee has n options for sick days and m options for personal days, the total number of days off the employee can take is n * m.

An employee has options for insurance, disability insurance, and a retirement plan: If the employee has n options for insurance, m options for disability insurance, and p options for a retirement plan, the total number of options the employee has is n * m * p.

An employee has five categories, each with six job functions: If each category has n options for job functions and there are five categories, the total number of job functions the employee has is 5 * n.

An employee has the option to choose the number of deductions for taxes: If the employee has n options for the number of deductions, the total number of options the employee has is n.

In each of these situations, the Fundamental Counting Principle allows us to calculate the total number of outcomes or options by multiplying the number of choices for each independent event.

The largest possible domain of W(t) is [0, 300].

Levi has 5 hours to work on a research paper and he can type 80 words per minute. The function W(t) = 80t represents the number of words Levi produces in t minutes of typing. We want to find the largest possible domain of W(t). The domain of W(t) is the set of all possible input values of t that make the function W(t) defined. So, we need to find out the maximum number of minutes Levi can work for. We know that he has 5 hours to work, and there are 60 minutes in one hour.

Therefore, he has a total of: 5 hours × 60 minutes/hour = 300 minutes Thus, the domain of W(t) is the set of all real numbers between 0 and 300 inclusive. We include 0 because Levi can type for 0 minutes (i.e. he hasn't started typing yet), and we include 300 because that's the maximum number of minutes he has available to type in.

Therefore, the ship was carrying 180 tons of ice when it set sail.

In 1833, a ship arrived in Calcutta with 120 tons of remaining cargo of ice, and one third of the original cargo was lost due to melting on the voyage.

We need to determine the original amount of cargo of ice the ship was carrying when it set sail.

Let's solve this problem step-by-step.

Step 1:

Let's denote the original amount of cargo of ice the ship was carrying when it set sail as x.

Step 2:

One-third of the original cargo was lost due to melting on the voyage.

Thus, the remaining two-thirds cargo of ice reached Calcutta.

Hence, the remaining cargo of ice was 120 tons.

We can write it mathematically as; 2/3 x = 120 tons

Step 3:

Solving for x, the original amount of cargo of ice the ship was carrying,  we can cross-multiply the above equation as: 2x = 3 × 120 tons

2x = 360 tons

x = 360/2 tons

x = 180 tons

To find Randy's age now, we need to use the information provided about the ratio of Jeremy's age, Randy's age, and Kaden's age 10 years ago, as well as the sum of their present ages. By setting up equations based on the given information, we can solve for Randy's age now.

Let's assume that Jeremy's age 10 years ago was 4x, Randy's age was 3x, and Kaden's age was x. This satisfies the given ratio of 4:3:1.

Now, 10 years have passed, so we need to consider their present ages. Jeremy's present age would be 4x + 10, Randy's present age would be 3x + 10, and Kaden's present age would be x + 10.

The sum of their present ages is given as 102, so we can set up the equation:

(4x + 10) + (3x + 10) + (x + 10) = 102

Simplifying the equation, we have:

8x + 30 = 102

Subtracting 30 from both sides, we get:

8x = 72

Answers

The vendor cannot purchase a fraction of a bushel, the vendor can afford to buy a maximum of 5 bushels of corn with the given amount of money.

To determine how many bushels of corn the vendor can afford to buy, we need to consider the cost of each bushel of corn and the fixed delivery fee. Here's how we can calculate it:

Subtract the fixed delivery fee from the total amount of money the vendor has:

$22.00 - $5.50 = $16.50

Divide the remaining amount of money by the cost per bushel of corn to find the maximum number of bushels the vendor can buy:

$16.50 ÷ $3.00 = 5.5 bushels

Since the vendor cannot purchase a fraction of a bushel, the vendor can afford to buy a maximum of 5 bushels of corn with the given amount of money.

school bag


How much wrapping paper will Ona need to cover the pyramid?

Answers

Olivia will need 280 square centimeters of wrapping paper to cover the pyramid for her history project.

To calculate the amount of wrapping paper Olivia will need to cover the pyramid, we need to find the total surface area of the pyramid, including the base and the triangular sides.

The base of the pyramid is a square, so its area can be found by squaring the length of one side. Given that the base length is 10 centimeters, the area of the base is 10^2 = 100 square centimeters.

The triangular sides of the pyramid are all congruent, so we can calculate the area of one triangular side and multiply it by the number of sides (4 in this case) to get the total area.

To find the area of one triangular side, we can use the formula for the area of a triangle:

Area = (1/2) * base * height

In this case, the base length is 10 centimeters, and the height is the slant height of 9 centimeters.

Area = (1/2) * 10 * 9 = 45 square centimeters

Since there are four triangular sides, the total area of the triangular sides is 4 * 45 = 180 square centimeters.To calculate the total surface area, we need to add the area of the base and the area of the triangular sides:

Total surface area = base area + triangular side area

Total surface area = 100 + 180 = 280 square centimeters

Therefore, Olivia will need 280 square centimeters of wrapping paper to cover the pyramid for her history project.

An angle is a geometric figure formed by two rays or lines that share a common endpoint called the vertex.

If Jen noticed that the angle formed at the corner of the soccer field was similar to her math lesson, we can explore the different types of angles she might be referring to.

Right Angle: A right angle measures exactly 90 degrees and forms a square corner. It is a common angle found in everyday life, such as the corners of buildings or the intersection of two perpendicular lines. Right angles are often studied in geometry due to their properties and applications in various mathematical concepts.

Acute Angle: An acute angle measures less than 90 degrees. It is a smaller angle that appears sharp and pointed. Examples of acute angles can be found in triangles, where all three angles are acute.

Obtuse Angle: An obtuse angle measures more than 90 degrees but less than 180 degrees. It is a wider angle that appears larger and open. Examples of obtuse angles can be found in shapes like rectangles or triangles with one angle greater than 90 degrees.

Straight Angle: A straight angle measures exactly 180 degrees, forming a straight line. It is a flat angle that doesn't bend or deviate. Straight angles are commonly found in line segments or in shapes like straight edges of polygons.

A regulation baseball has a diameter of about 3 in. What is the best approximation for the volume of this baseball? 14. 13 in³ 28. 26 in³ 84. 78 in³ 113. 04 in³ baseball with diameter of 3 inches.

Answers

The best approximation for the volume of a regulation baseball with a diameter of about 3 inches is 14 in³.

The volume of a sphere is given by the formula V = (4/3)πr³, where V represents the volume and r represents the radius. In this case, we have the diameter, which is 2 times the radius.

The radius of a baseball with a diameter of about 3 inches is approximately 3/2 = 1.5 inches.

Substituting the radius into the volume formula:

V = (4/3)π(1.5)³ = (4/3)(3.14)(1.5)³ = (4/3)(3.14)(3.375) ≈ 14 in³

Therefore, the best approximation for the volume of the baseball is 14 in³.

Around a park, there is a circular walking path with a radius of 500 feet. Sandy walked 135° around the circular path.


Approximately how many feet did Sandy walk around the path? Round your answer to the nearest whole foot

Answers

Sandy walked approximately 1,179 feet around the circular path. to calculate this, we can find the circumference of the circle by using the formula C = 2πr, where r is the radius.

In this case, the radius is 500 feet. So, the circumference is approximately 2π(500) = 3,141.59 feet. Since Sandy walked 135° around the path, we can find the fraction of the circle she covered by dividing 135° by 360°. The fraction is approximately 0.375. Multiplying this fraction by the circumference gives us 0.375 * 3,141.59 ≈ 1,178.96 feet, which rounds to 1,179 feet.

Sure! To calculate the approximate distance Sandy walked around the circular path, we first need to find the circumference of the circle. The formula for the circumference of a circle is C = 2πr, where r is the radius. In this case, the radius is given as 500 feet.

Substituting the value of the radius into the formula, we have C = 2π(500) = 1000π. However, it's more convenient to work with an approximate value of π, which is approximately 3.14159. Therefore, the circumference of the circle is approximately 1000 * 3.14159 = 3141.59 feet.

Now, we know that Sandy walked 135° around the circular path. To determine the distance she covered, we need to find the fraction of the circle that corresponds to this angle. Since a complete circle is 360°, the fraction of the circle she covered is 135° / 360° = 0.375.

To find the distance Sandy walked, we multiply this fraction by the circumference of the circle. Therefore, 0.375 * 3141.59 = 1178.96 feet. Rounding this value to the nearest whole foot, Sandy walked approximately 1179 feet around the circular path.

Answers

To calculate Elizabeth's finance charge using the previous balance method, we need to determine the average daily balance and then apply the APR (Annual Percentage Rate) to calculate the finance charge.

First, let's calculate the average daily balance:

Beginning Balance: $969.26

Days until payment: 2 (from July 1st to July 3rd)

Payment: $45.00

Days until purchase: 7 (from July 3rd to July 10th)

Purchase: $67.48

Days until payment: 2 (from July 10th to July 12th)

Payment: $20.00

Days until payment: 16 (from July 12th to July 28th)

Payment: $85.00

To calculate the average daily balance, we sum up the balances for each day and divide it by the total number of days in the billing cycle (30 days).

Average Daily Balance = (969.26 × 2 + 0 × 7 + 67.48 × 2 + 0 × 16) / 30 = $85.95

Next, we can calculate the finance charge using the APR:

Finance Charge = Average Daily Balance × (APR / 365) × Number of Days in the Billing Cycle

Finance Charge = 85.95 × (0.1461 / 365) × 30 ≈ $9.97

Therefore, Elizabeth's July finance charge will be approximately $9.97. The correct answer is option a.

Carol had $15,500 in visa sales one month. How much more did she net than if sales had been $14,300?

Answers

Carol netted $1,200 more with $15,500 in Visa sales compared to if sales were $14,300.

1. Calculate the difference between the two sales amounts: $15,500 - $14,300 = $1,200.

By subtracting $14,300 from $15,500, we find that Carol's sales were $1,200 higher with $15,500 in Visa sales.

2. The sales amount represents the total revenue generated from Visa transactions, but to determine how much Carol "netted," we need to consider any expenses or costs associated with these sales.

3. Subtract any expenses or costs from the total revenue to calculate the net amount. However, since the question does not provide information about expenses or costs, we'll assume that the sales amount refers to the net amount.

4. Therefore, the difference of $1,200 represents the additional money Carol received with $15,500 in Visa sales compared to if sales were $14,300.

In order for a ladder to reach a height of 10 feet it needs to be placed at a 75⁰ angle to the ground. The ground already has an elevation of 15⁰.what degree does the ladder need to me set at?

Answers

To reach a height of 10 feet while accounting for the ground elevation of 15⁰, the ladder needs to be set at an angle of approximately 80.77⁰.

When placing the ladder on the ground, we need to consider both the desired height and the ground elevation. Let's denote the angle at which the ladder needs to be set as x⁰.

To find the value of x⁰, we can use trigonometry. In this case, we'll use the tangent function. The tangent of an angle is equal to the ratio of the length of the opposite side to the length of the adjacent side. In this scenario, the opposite side is the height of the ladder (10 feet), and the adjacent side is the horizontal distance the ladder needs to cover on the ground.

The tangent of an angle is given by the formula: tan(x⁰) = opposite/adjacent.

To calculate the adjacent side, we can use the height of the ladder and the ground elevation angle: adjacent = height / tan(ground elevation).

Plugging in the values, we have: adjacent = 10 / tan(15⁰).

Solving this equation gives us the value of the adjacent side. We can then find x⁰ by taking the arctan of the ratio: x⁰ = arctan(adjacent/height).

Calculating this value, we find x⁰ ≈ 80.77⁰.

Therefore, the ladder needs to be set at an angle of approximately 80.77⁰ to reach a height of 10 feet, accounting for the ground elevation of 15⁰.

A subwoofer box for sound costs $260. 40 after a price increase. The cost before the price increase was $240. 0. What was the approximate percent of the price increase


Will be awarded brainliest :) PLS HELPP

Answers

The approximate percent of the price increase is approximately 8.5%. To find the approximate percent of the price increase, we can use the following formula: Percent Increase = ((New Value - Old Value) / Old Value) * 100

To calculate the approximate percent of the price increase, we can follow these steps:

Determine the old value: In this case, the old value is the cost before the price increase, which is given as $240.0.

Determine the new value: The new value is the cost after the price increase, which is given as $260.40. Calculate the difference: Subtract the old value from the new value to find the increase in price. In this case, it is $260.40 - $240.0 = $20.40.

Calculate the percent increase: Divide the difference by the old value, then multiply by 100 to express it as a percentage. In this case, it is (20.40 / 240.0) * 100 ≈ 8.5%.

Therefore, the approximate percent of the price increase is approximately 8.5%. This means that the price increased by around 8.5% from its original value of $240.0 to the new value of $260.40.

Determine whether the polygons are similar. If they are, write a similarity statement and give the scale factor.


A. RST=WUV; 5/6


B. RST=UVW; 5/6


C. RST=VWU; 6/5


D. The Triangles are not similar

Answers

To determine whether the polygons RST and WUV are similar, we need to compare their corresponding angles and corresponding side lengths.

Looking at the options provided:

A. RST = WUV; 5/6

B. RST = UVW; 5/6

C. RST = VWU; 6/5

D. The triangles are not similar

We can see that options A, B, and C all claim that RST is similar to another polygon.

However, for polygons to be similar, corresponding angles must be congruent, and corresponding side lengths must be proportional. Since the scale factor is consistent in all three options (5/6 or 6/5), the scale factor is the same for corresponding side lengths.

Therefore, we can conclude that the polygons RST and WUV are similar, and the similarity statement is:

RST ~ WUV

The scale factor is 5/6 (or 6/5), indicating that corresponding side lengths are proportional by a factor of 5/6 (or 6/5).
