nearest hundredth

Answers

Answer 1

The perimeter of the square ABCD, can be found to be 14.14 cm and the area would be 12.52 cm².

How to find the perimeter and area of a square?

If the side of the larger square is 5 cm, then the diagonal of the smaller square ABCD is 5 cm because the diagonal connects two midpoints on adjacent sides of the larger square.

The sides of the smaller square can be found by applying the Pythagorean theorem, which in this case is a 45-45-90 right triangle theorem.

Given that in a 45-45-90 triangle, the sides are in the ratio of 1:1:√2, the sides of the smaller square (a) can be calculated as follows:

a = 5 / √2

= 5 x √2/2

=  3.54 cm

The perimeter of the square is:

= 4 x 3. 54

= 14. 14 cm

The area is:

= 3. 54 x 3. 54

= 12. 53 cm²

Solve for the missing parts of the triangle. Angle A and AC show all work

Answers

triangle ABC with angle A and AC missing, we need to solve for the missing parts of the triangle.

Step-by-step explanation:We are given triangle ABC, with angle A and side AC missing. To solve for the missing parts of the triangle, we can use the properties of triangles and trigonometry.Let's start by finding angle A. We know that the sum of angles in a triangle is 180°.

Therefore, we can write:∠A + ∠B + ∠C = 180°

Substituting the values we know, we get:∠A + 60° + 45° = 180°

Simplifying the equation, we get:∠A = 180° - 60° - 45°∠A = 75°

Therefore, angle A measures 75°.Now, we can use trigonometry to find the length of side AC. Since we know the length of sides AB and BC, we can use the Law of Cosines to find the length of AC.

The Law of Cosines states that: c² = a² + b² - 2ab cos(C)

where a, b, and c are the lengths of sides of a triangle, and C is the angle opposite to side c.

Substituting the values we know, we get:AC² = AB² + BC² - 2(AB)(BC) cos(A

)AC² = 6² + 8² - 2(6)(8) cos(75°)

AC² = 36 + 64 - 96 cos(75°)

AC² = 100 - 96 cos(75°)

Using a calculator, we can find that cos(75°) = 0.2588. Substituting this value, we get:AC² = 100 - 96(0.2588)AC² = 100 - 24.8448AC² = 75.1552

Taking the square root of both sides, we get:AC ≈ 8.67

Therefore, side AC has a length of approximately 8.67 units.

Sabrina can type 2 ⅖ pages per hour. How many pages can she type in 8 hours and 20 minutes?

Answers

a) Sabrina can type 2 ⅖ pages per hour. To find out how many pages she can type in 8 hours and 20 minutes, we need to convert the time to hours.

b) To convert 8 hours and 20 minutes to hours, we divide the minutes by 60 and add the result to the number of hours. Then, we multiply the total number of hours by Sabrina's typing rate of 2 ⅖ pages per hour to find the total number of pages she can type.

a) Sabrina's typing rate is given as 2 ⅖ pages per hour. This means she can type 2 and two-fifths of a page in one hour.

b) To calculate the total number of pages Sabrina can type in 8 hours and 20 minutes, we convert the time to hours. Since there are 60 minutes in an hour, we divide the minutes by 60 to convert them to hours. In this case, 20 minutes divided by 60 equals 1/3 hours. Adding this to the 8 hours gives us a total of 8 and 1/3 hours.

Next, we multiply the total number of hours (8 1/3) by Sabrina's typing rate (2 ⅖ pages per hour). To multiply fractions, we multiply the numerators and denominators separately. The result is (25/3) * (12/5) = 300/15 = 20 pages.

Suppose we spin the wheel, observe the color that the pointer stops on, and repeat the process until the pointer stops on blue. What is the probability that we will spin the wheel exactly three times?.

Answers

The overall probability can be calculated as P(exactly three spins) = (1 - P(blue)) × (1 - P(blue)) × P(blue).

To determine the probability of spinning the wheel exactly three times until the pointer stops on blue, we need to understand the given conditions and calculate the likelihood of this specific outcome.

Assuming the wheel has multiple colors and the pointer stops on one color each time, we'll focus on the probability of stopping on blue after spinning the wheel three times.

Let's consider the possible outcomes for each spin. Assuming each spin is independent and the probability of stopping on blue is constant, the probability of stopping on blue for a single spin is denoted as P(blue).

To calculate the probability of spinning the wheel exactly three times until stopping on blue, we multiply the probabilities of not stopping on blue for the first two spins and then stopping on blue on the third spin. Since the spins are independent, we multiply the probabilities together.

The probability of not stopping on blue for the first two spins is given by (1 - P(blue)) × (1 - P(blue)). The probability of stopping on blue on the third spin is simply P(blue).

Thus, the overall probability can be calculated as:

P(exactly three spins) = (1 - P(blue)) × (1 - P(blue)) × P(blue).

Without knowing the specific alue of P(blue), we cannot provide an exact numerical probability. However, if the probability of stopping on blue for a single spin is known, it can be substituted into the formula above to calculate the probability of spinning the wheel exactly three times until stopping on blue.

Arcadia is 7 miles due north of the airport, and Rockport is 6 miles due east of the airport. How far apart are Arcadia and Rockport? If necessary, round to the nearest tenth.

Answers

The distance between Arcadia and Rockport is approximately 9.2 miles when rounded to the nearest tenth.

To determine the distance between Arcadia and Rockport, we can use the Pythagorean theorem, which relates the lengths of the sides of a right triangle.

Let's consider Arcadia as point A, Rockport as point R, and the airport as point O. The distance from Arcadia to the airport is 7 miles (the length of side OA), and the distance from Rockport to the airport is 6 miles (the length of side OR). We want to find the distance between Arcadia and Rockport, which is the length of side AR.

Since Arcadia and Rockport are located in different directions (north and east) from the airport, we can form a right triangle with sides AO, OR, and AR.

Using the Pythagorean theorem, we have:

AR^2 = AO^2 + OR^2.

Substituting the given lengths, we get:

AR^2 = 7^2 + 6^2,

AR^2 = 49 + 36,

AR^2 = 85.

Taking the square root of both sides, we find:

AR = √85.

Approximating the square root of 85 to the nearest tenth, we have:

AR ≈ 9.2 miles.

Therefore, the distance between Arcadia and Rockport is approximately 9.2 miles when rounded to the nearest tenth.

It's important to note that this calculation assumes a direct path between Arcadia and Rockport. If there are obstacles or detours that would affect the actual path, the distance may differ. Additionally, rounding to the nearest tenth introduces some level of approximation, so the actual distance may be slightly different.

Answers

The value closest to the estimated average pet car population for European countries in 2010 is 15 million.

Given the table for pet car populations in 2002, we need to estimate the average pet car population for European countries in 2010 after each car population has doubled.

It can be observed that in 2002, Spain and Italy had the lowest pet car population while Germany and the United Kingdom had the highest.

In order to find the estimated average pet car population for European countries in 2010, we first need to find the pet car population for each country in 2010 after doubling their 2002 population.

The results are shown in the table below:

|Country|Pet car population in 2002

|Pet car population in 2010|

|-|-|-|

|France|22 million

|44 million|

|Germany|

30 million|

60 million|

|Italy|

8 million|

16 million| |Spain|6 million|12 million| |United Kingdom|28 million|56 million|

To find the estimated average pet car population for European countries in 2010, we need to sum up the pet car populations for all the countries in 2010 and then divide by the total number of countries (which is 5).

Adding all the pet car populations in 2010:

44 million + 60 million + 16 million + 12 million + 56 million = 188 million

The estimated average pet car population for European countries in 2010, closest to the calculated value, would be:

188 million/5 ≈ 38 million

Now, we need to find which of the given options is closest to this value. We can see that the option closest to 38 million is D.) 12 million.

However, this value is not the answer since it is too low compared to the estimated average.

Therefore, we can rule out option

D.) as the answer.

Now, we can look at the remaining options to determine which is closest to the average.

Option A.) 9 million is clearly too low, and

option C.) 18 million is too high.

Therefore, the answer is

What is the value of the other variable? ft

Answers

The independent variable in the equation a=15−(b+6) is b. If the architect wants b to be 3, it means that the distance between the floor and the bottom of the window is 3 feet, and for this to work, a must be 6 feet. The customer wants 5 feet of space above the window, which means that b must be 4 feet.

Part A:

The independent variable is the variable that can be freely chosen or varied. In the given equation a=15−(b+6), the independent variable is b because we can choose any value of b and then calculate the corresponding value of a using the equation.

Part B:

If the architect wants b to be 3, this means that the distance between the floor and the bottom of the window is 3 feet.

This would work if a is 6 feet, because:

a = 15 - (b + 6)

a = 15 - (3 + 6)

a = 6

Therefore, if b is 3, then a must be 6 for the relationship described by the equation to hold.

Part C:

The customer wants the window to have 5 feet of space above it. This means that the distance between the top of the window and the ceiling is 5 feet. According to the equation, we know that:

a = 15 - (b + 6)

So we can substitute the value of a as 5 and solve for b:

5 = 15 - (b + 6)

5 = 9 - b

b = 4

Therefore, the value of b is 4 feet when the customer wants the window to have 5 feet of space above it.

Relative to ground level, what is the elevation of the hole after placing the bush in the hole? Enter your answer as a mixed number in simplest form by filling in the boxes.

Answers

The elevation of the hole, relative to ground level, after placing the bush in the hole is 52 2/5 feet.

In 30 minutes, Carter digs 34 feet every 10 minutes, so in 30 minutes, he digs a total of (34/10) x 30 = 102 feet. After placing the bush, the hole is filled with 78 feet. So, the elevation of the hole after placing the bush is 102 - 78 = 24 feet below ground level. This can be expressed as a mixed number in simplest form as 52 2/5 feet above ground level.

Sure, let's break down the problem step by step:

1. Carter digs a hole at a rate of 34 feet every 10 minutes. This means that in 10 minutes, he digs 34 feet.

2. To determine how much Carter digs in 30 minutes, we can set up a proportion: 10 minutes is to 34 feet as 30 minutes is to x feet. Solving this proportion, we find that x = (34/10) * 30 = 102 feet. Therefore, Carter digs a total of 102 feet in 30 minutes.

3. After 30 minutes of digging, Carter places a bush in the hole that fills exactly 78 feet of the hole. This means that the hole is no longer empty but has been filled with 78 feet.

4. To find the elevation of the hole relative to ground level, we need to subtract the filled portion (78 feet) from the total depth of the hole that Carter dug (102 feet). This results in 102 - 78 = 24 feet.

5. The elevation of the hole, relative to ground level, is 24 feet below the ground. However, we need to express it as a mixed number in simplest form. Since each whole number is equal to 5/5, we can rewrite 24 as 23 + 1 = 23 + (5/5) = 23 + 1(5/5) = 23 5/5. Simplifying this mixed number, we get 23 1/5 feet.

Therefore, the elevation of the hole, relative to ground level, after placing the bush in the hole is 23 1/5 feet.

2x - 3.80 = 12.78

2x = 16.58

x = 8.29

Therefore, the original price of one jump rope was $8.29.

To check our answer, we can verify that the sale price of one jump rope is $6.39 ($8.29 - $1.90), and that two jump ropes at this price cost $12.78.

The average weight of adult male bison in a particular federal wildlife preserve is 1650 pounds with a standard deviation of 250 pounds. Find the weight of an adult bull whose z-score is –0.5.

Answers

If the average weight of adult male bison is 1650 pounds with a standard deviation of 250 pounds. Then the weight of an adult bull whose z-score is –0.5 will be 1525 pounds.

To find the weight of an adult bull whose z-score is -0.5, we can use the formula for z-score:

z = (x - μ) / σ

Where:

- z is the z-score

- x is the value we want to find (weight of the adult bull)

- μ is the mean weight of adult male bison (1650 pounds)

- σ is the standard deviation (250 pounds)

Rearranging the formula to solve for x:

x = z * σ + μ

Substituting the given values:

x = -0.5 * 250 + 1650

x = -125 + 1650

x = 1525 pounds

Therefore, the weight of an adult bull with a z-score of -0.5 is 1525 pounds.

What is the length of the missing base of the trapezoid?A trapezoid with longer base labeled 8 inches and height labeled 3 inches. The area of the trapezoid is labeled 21 square inches.

Answers

To find the length of the missing base of the trapezoid, we can use the formula for the area of a trapezoid. Given that the longer base is 8 inches, the height is 3 inches, and the area is 21 square inches, we can substitute these values into the formula and solve for the missing base length.

The formula for the area of a trapezoid is A = (1/2)(b1 + b2)h, where A is the area, b1 and b2 are the lengths of the bases, and h is the height.

In this case, we know that b1 is 8 inches and h is 3 inches, and the area A is 21 square inches. We need to find the length of the missing base, which we'll denote as b2.

Substituting the known values into the formula, we have:

21 = (1/2)(8 + b2)(3)

Simplifying the equation, we get:

42 = 8 + b2

Subtracting 8 from both sides, we find:

b2 = 34

Therefore, the length of the missing base of the trapezoid is 34 inches.

Ifyou improves your typing speed 80% from 50 words per minutes. Who many words youcan type now in one minutes.

Answers

With an 80% improvement in typing speed from an initial rate of 50 words per minute, you will be able to type 90 words per minute.

Increasing your typing speed by 80% means you will be able to type 80% more words in the same amount of time. Therefore, if your initial typing speed is 50 words per minute, an 80% improvement would result in a typing speed of 90 words per minute.

To calculate the new typing speed, we first find 80% of the initial typing speed.

80% of 50 is (80/100) * 50 = 0.8 * 50 = 40.

This means that your typing speed will increase by 40 words per minute.

To determine the new typing speed, we add the increase to the initial typing speed:

50 + 40 = 90.

Thus, after the 80% improvement, you will be able to type 90 words per minute.

In summary, with an 80% improvement in typing speed from an initial rate of 50 words per minute, you will be able to type 90 words per minute.

What are the factors of x2 − 64? Prime (x − 4)(x 16) (x − 8)(x − 8) (x 8)(x − 8).

Answers

The factors of x^2 - 64 are (x - 8)(x + 8) because it follows the difference of squares formula, giving the correct factorization that yields x^2 - 64 when multiplied.

To factorize x^2 - 64, we can use the difference of squares formula, which states that a^2 - b^2 can be factored as (a - b)(a + b). In this case, a = x and b = 8. Applying the formula, we have (x - 8)(x + 8) as the factors of x^2 - 64. This is the correct factorization because when we multiply these factors, we get (x - 8)(x + 8) = x^2 - 64.

The other options provided (x - 4)(x + 16) and (x - 8)(x - 8) are not valid factorizations of x^2 - 64. The first option, (x - 4)(x + 16), does not yield x^2 - 64 when multiplied. The second option, (x - 8)(x - 8), is a repeated factor and does not represent the correct factorization. Therefore, the factors of x^2 - 64 are (x - 8)(x + 8).

A bacteria cell reproduces by splitting in half. Write an explicit formula that can be used


to find the number of bacteria cells after each generation. Then use the formula to find


how many cells there are after 10 generations. Show your work.

Answers

The explicit formula is [tex](n) = 1 * 1^{(n-1)} = 1[/tex] for all values of n and the number of cells after 10 generations will be 1.

The formula for finding the number of bacteria cells after each generation is given by

[tex]a(n) = a(1)r^{(n-1)}[/tex] where a(1) is the initial number of bacteria cells, r is the growth factor, and n is the number of generations.

The exponent n-1 indicates the number of generations.

To find the number of bacteria cells after 10 generations, we will substitute the given values in the formula.

We are given that a(n)= a(1)r"-1 where r is the growth factor and n is the number of generations.

We know that the initial number of bacteria cells is 1.

Thus, a(1) = 1.

Substituting these values in the formula, we get [tex]a(n) = 1 x r^{(n-1)}[/tex]. For 10 generations, n = 10.

Thus, the formula becomes [tex]a(10) = 1 x r^{(10-1)} = r^9[/tex].

Now, we need to find the value of r.

We are given that [tex]a(n) = a(1)r^{(-1)}[/tex], which means that a(n)/a(1) = 1/r.

Substituting [tex]a(n) = r^9[/tex] and a(1) = 1, we get: [tex]r^9/1 = 1/r[/tex]

Therefore, [tex]r^{10} = 1r = 1^{(1/10)} = 1[/tex]

Thus, the explicit formula becomes [tex]a(n) = 1 * r^{(n-1)}[/tex] = 1 for all values of n.

Therefore, the number of cells after 10 generations will be 1.

Summary: A formula that can be used to find the number of bacteria cells after each generation is [tex]a(n) = 1 * r^{(n-1)}[/tex] where a(1) is the initial number of bacteria cells, r is the growth factor, and n is the number of generations. To find the number of bacteria cells after 10 generations, we can substitute the given values in the formula. The explicit formula for the given problem is [tex]a(n) = 1 * r^{(n-1)}[/tex] where r = 1. Thus, the number of cells after 10 generations will be 1.

Answers

Given information:

Max invest $1000 in a savings account that earns simple 3% interest.

Let's suppose the duration he needs to keep his money in the savings account is t years.

The interest rate is given as 3% in decimal form = 0.03

Max invests $1000 on the savings account that earns 3% simple interest.

This implies that the interest he will earn after t years is given by:

Interest (I) = Principal × Rate × Time

I = 1000 × 0.03 × t

I = 30t

From the problem, he wants to earn $150 in interest.

So, 30t = 150

Solving for t:

$$\begin{aligned}30t &= 150 \\t &= \frac{150}{30} \\t &= 5 \;years \end{aligned}$$

Max needs to leave his money in the savings account for 5 years to make $150 in interest.

3 integers, all less than 20

range is 7

mean is 12

Answers

The three integers are 10, 12 and 14.

To find three integers that satisfy the given conditions, we can use the properties of range and mean.

Let's assume the three integers are x, y, and z.

Range is the difference between the largest and smallest values. In this case, the range is given as 7. Therefore, we can set up the equation:

max(x, y, z) - min(x, y, z) = 7.

Mean is the average of the values. The mean is given as 12. Therefore, we can set up the equation:

(x + y + z) / 3 = 12.

We also know that all three integers are less than 20.

Let's solve these equations simultaneously:

From the equation for the mean, we can rewrite it as:

x + y + z = 36.

Now, let's list all the possible combinations of three integers that satisfy the given conditions:

x = 9, y = 12, z = 15

x = 10, y = 12, z = 14

x = 11, y = 12, z = 13

Out of these combinations, only the second one satisfies the condition that all three integers are less than 20.

Therefore, the three integers that meet the given conditions are:

x = 10, y = 12, z = 14.

Using algebraic equations, the value of the number assumed to be x is 13.

Let's assume that the number in question be "x". Thus, the expression can be written as:

2x + 9 = 5 (x - 6).

Let's solve this equation and find the value of x:

Distributing the 5 across the parentheses,

2x + 9 = 5x - 30  

Subtracting 2x from both sides,

we get, 3x = 39  

Dividing both sides by 3,

x = 13
