Devon bought a new suit that was discounted 40% off the original price. If the original price of the suit was $280, what was the discounted price?
The discounted price of the suit is $168.
Explanation: To calculate the discounted price, we need to subtract the discount percentage from 100% and then multiply it by the original price. In this case, the original price of the suit is $280, and it was discounted by 40%.
First, we calculate the discount amount:
Discount amount = Original price * (Discount percentage / 100)
Discount amount = $280 * (40 / 100)
Discount amount = $280 * 0.4
Discount amount = $112
Next, we will subtract the discount amount from the original price to find the discount price:
Discounted price = Original price - Discount amount.
Discounted price = $280 - $112
Discounted price = $168
Therefore, the discounted price of the suit is $168 after applying a 40% discount to the original price of $280.

When calculating the effective rate of a loan, which statement or statements must be true if n is equal to 1? I. The nominal rate equals the effective rate. II. The length of the loan is exactly one year. III. The interest is compounded annually. A. I and III b. II and III c. I only d. III only Please select the best answer from the choices provided A B C D.
The statement that must be true when calculating the effective rate of a loan with n = 1 is: III. The interest is compounded annually. Therefore, the answer is d. III only.
When n equals 1, it means that the interest is compounded once per year. In this case, the effective rate of the loan is equal to the nominal rate since there are no additional compounding periods within the year.
This is because when n equals 1, there is no need to consider the length of the loan (statement II) since it is already implied that the loan is for one year.
However, statement I, which states that the nominal rate equals the effective rate, may not necessarily be true for loans with other values of n. Hence, only statement III is required to be true when n equals 1 to calculate the effective rate of a loan.

A fair die is rolled 3 times. The first 2 rolls resulted in 2 threes. What is the probability of not rolling a 3 on the next roll?
a. 1
b.(1/6)^2 x (5/6)
c. (3!/2!5!) x (1/6)^2 x (5/6)
d. 5/6
e. 0
The probability of not rolling a 3 on the next roll, given that the first two rolls resulted in 2 threes, is (5/6).
Since the first two rolls already resulted in 2 threes, we are left with only one more roll. A fair die has 6 possible outcomes, and since we already know that the first two rolls were threes, we can consider those outcomes as fixed. Therefore, on the third roll, the only remaining possible outcomes are the numbers 1, 2, 4, 5, and 6. Out of these 5 remaining outcomes, only 1 of them is not a 3. Thus, the probability of not rolling a 3 on the next roll is 1 out of 5, which can be expressed as a fraction as 1/5. Simplifying this fraction further, we get 1/5 = 1/6. Therefore, the correct answer is (5/6).
Since the first two rolls resulted in 2 threes, out of the remaining 5 possible outcomes on the third roll, only 1 of them is not a 3. Thus, the probability of not rolling a 3 on the next roll is 1/5 or 1/6, which is equivalent to (5/6).

When Lorretta was 18 years old, she deposited $100 into a 20-year certificate of deposit (CD) account that earns interest at a better rate than her standard savings account. She must leave the money in the account for 20 years, without making any withdrawals or deposits. Six years later, she had $132 in the account. Write an equation that will represent this situation, and use the equation to determine how much money.
this has to be in y=ab^x form and we have to solve using logarithm rules but I wasn't there for that lesson
Therefore, the amount of money in the CD after 6 years is $200.76.
Given that Loretta was 18 years old when she deposited $100 into a 20-year certificate of deposit (CD) account that earns interest at a better rate than her standard savings account and she must leave the money in the account for 20 years, without making any withdrawals or deposits.
Six years later, she had $132 in the account.The formula for the growth of money at a compounded rate is given by
y =[tex]a (1 + r/n)^_(nt)[/tex]
Where
y = the amount of money at the end of the period.
a = the initial amount of money.
r = the annual interest rate in decimal form.
n = the number of times compounded per year.
t = the number of years.
The initial deposit was $100, and the total amount after 20 years would be $132. So, we have
$132 =[tex]$100(1 + r/n)^_(nt)[/tex]
Taking the natural logarithm of both sides,ln 132
= [tex]ln(100) + ln(1 + r/n)^{(nt)}ln 132 - ln 100[/tex]
= nt ln (1 + r/n)ln (132/100)
= nt ln (1 + r/n)ln (1.32)
= nt ln (1 + r/n)ln (1.32)
= t ln (1 + r/n)ln (1 + r/n)
= ln (1.32)ln (1 + r/n)
= 0.2877
Since the number of times compounded per year is not given, it can be assumed that it is compounded annually.i.e., n = 1
Therefore,ln (1 + r/1)
= 0.2877ln (1 + r)
= 0.2877r
= [tex]e^{(0.2877)} - 1r[/tex]
= 0.3338
So, the rate of interest is 33.38%.
Therefore, the equation for the amount of money in the CD after t years is
y = [tex]100(1 + 0.3338)^t[/tex]
Thus, the amount of money at the end of 6 years is
y = [tex]100(1 + 0.3338)^6[/tex]

brian buys a computer for £1600
it depreciates at a rate of 4% per year
how much will it be worth in 3 years
Brian's computer will be worth £1408 in 3 years if it depreciates at a rate of 4% per year. Depreciation is a measure of how much the asset has lost in value over a period of time.
Depreciation refers to a decrease in the value of an asset over time due to its wear and tear or obsolescence. When an asset is purchased, it has an original value that is its initial worth. After some time, the asset will lose its value and become less valuable. Depreciation is a measure of how much the asset has lost in value over a period of time.
In this problem, Brian bought a computer for £1600, and it depreciates at a rate of 4% per year. To find out how much it will be worth in 3 years, we need to use the formula for depreciation which is:
Depreciation = Original value × rate of depreciation (as a decimal) × time (in years)
To calculate the depreciation, we have:
Depreciation = 1600 × 0.04 × 3= £192.
The depreciation value is what the computer will be worth in 3 years. Therefore, we can find the current value of the computer by subtracting the depreciation value from the original value. Hence, we have:
Current value = Original value - Depreciation= £1600 - £192= £1408.
Therefore, the computer will be worth £1408 in 3 years.

The farmer sold 2.42 kilograms of apples at the farmer's market.
To solve the problem, first, we need to find out how much weight the farmer sold in pears.
We are given that 3/4 of the weight is pears and 1/4 of the weight is apples.
We can use this information to set up an equation that represents the weight of the pears sold.
Let the weight of pears sold be "x":
Weight of pears sold + Weight of apples sold = Total weight of fruit sold
3/4x + 1/4x = 7.3 kg
Simplifying this equation, we get:
x = 4.88 kg
This means that the farmer sold 4.88 kg of pears.
To find out how many kilograms of apples she sold, we can subtract this weight from the total weight of fruit sold:
Weight of apples sold = Total weight of fruit sold - Weight of pears sold
Weight of apples sold = 7.3 kg - 4.88 kg
Weight of apples sold = 2.42 kg

The weight of 60 nuts and 50 bolts would be 9.25 kg.
We have to given that,
An order of 50 nuts and 60 bolts weighed 10.6kg.
And, An order of 40 nuts and 30 bolts weighed 6.5kg.
Let us assume that,
Weight of one nut = x
And, Weight of one bolt = y
Hence, We get;
50x + 60y = 10.6 .. (i)
And, 40x + 30y = 6.5 .. (ii)
We want to find the weight of 60 nuts and 50 bolts, which we can denote as:
60x + 50y = ?
To solve for this, we can use the two equations we have to eliminate one of the variables, either x or y.
Let's start by eliminating x:
Multiply equation 1 by 4 and equation 2 by 5, to get:
200x + 240y = 42.4 (equation 3)
200x + 150y = 32.5 (equation 4)
Subtract equation 4 from equation 3:
90y = 9.9
y = 0.11
Now we can substitute y = 0.11 into equation 2 to solve for x:
40x + 30(0.11) = 6.5
40x = 2.5 x = 0.0625
Therefore, the weight of 60 nuts and 50 bolts would be:
60(0.0625) + 50(0.11) = 3.75 + 5.5 = 9.25 kg
So 60 nuts and 50 bolts would weigh 9.25 kg.

On one night, a scientist needs to determine the distance she is away from the International Space Station. At the specific time she is determining this the space station distance they are both on the same line of longitude 77° E. Furthermore, she is on a latitude of 29° N and the space station is orbiting just above a latitude of 61.4° N. In short, the central angle between the two is 32.4°. If the Earth's radius is 3959 miles and the space station orbits 205 miles above the surface of the Earth, then how far is the scientist away from the space station?
The scientist is approximately 3933 miles away from the International Space Station.
To determine the distance between the scientist and the International Space Station, we can use the law of cosines. The law of cosines states that in a triangle, the square of one side is equal to the sum of the squares of the other two sides minus twice the product of their lengths and the cosine of the included angle.
In this case, the Earth's radius (r) is 3959 miles, and the space station orbits 205 miles above the surface of the Earth. The central angle between the scientist and the space station is 32.4°. Using the law of cosines, we can calculate the distance (d) between them as follows:
d² = r² + (r + h)² - 2r(r + h)cos(32.4°)
where h is the height of the space station above the Earth's surface. Plugging in the values, we get:
d² = 3959² + (3959 + 205)² - 2 * 3959 * (3959 + 205) * cos(32.4°)
Simplifying this equation gives us:
d ≈ 3933 miles
Therefore, the scientist is approximately 3933 miles away from the International Space Station.

Would the function describing the relationship between the denomination of U.s. currency and the weight of one million dollars be a discrete function or a continuous function
The relationship between the denomination of U.S. currency and the weight of one million dollars can be categorized as a discrete function. A discrete function is one where the input values are distinct and separate, with no intermediate values between them.
In the context of U.S. currency, the denominations are well-defined and specific, such as $1, $5, $10, $20, and so on. Each denomination corresponds to a specific weight when considering one million dollars.
For example, if we consider $1 bills, the weight of one million dollars would be significantly different from the weight of $5 bills or $10 bills. The weight is directly associated with the discrete values of the denominations.
On the other hand, a continuous function would involve a relationship where the input values vary continuously within a range. In this case, there is no continuous range of values for the denomination of U.S. currency. Each denomination has a specific weight, and there are no intermediate values between them.
Therefore, the relationship between the denomination of U.S. currency and the weight of one million dollars can be categorized as a discrete function, where the specific denominations correspond to distinct and separate weights.

Which function is correct for Adrianne's purposes? f(x) = 67(5)x f of x equals 467 times 5 to the 12 power to the x over 12 power f(x) = 467(5 to the one fourth power)4x f(x) = 4672(5)x.
The correct function for Adrianne's purpose, where the growth is calculated every 3 months instead of every year, is f(x) = 467(5^(x/4)).
To calculate the growth every 3 months instead of every year, we need to modify the original function by adjusting the exponent of 5.
Step 1: The original function is f(x) = 467(5)^x, where x represents the number of years.
Step 2: To calculate the growth every 3 months, we divide x by 4, as there are 12 three-month periods in a year.
Step 3: Adjust the exponent of 5 to (x/4), representing the growth over each three-month period.
Step 4: The modified function becomes f(x) = 467(5^(x/4)), which calculates the growth every 3 months.
Therefore, the correct function for Adrianne's purpose is f(x) = 467(5^(x/4)).

Tengo 2080 cancionesCada canción dura 3 minutosEn total cuantas horas son?
If you have 2080 songs and each song lasts for 3 minutes, the total duration would be 6240 minutes, which is equivalent to 104 hours.
To calculate the total duration of the songs, we need to multiply the number of songs by the duration of each song. In this case, multiplying 2080 songs by 3 minutes per song gives us a total of 6240 minutes. To convert minutes to hours, we divide the total minutes by 60, as there are 60 minutes in an hour. So, 6240 minutes divided by 60 equals 104 hours. Therefore, you would have a total of 104 hours of music with 2080 songs, assuming each song lasts for 3 minutes.

Tom’s house is 65 miles from the beach. A map uses a scale factor of ½ inch : 3 miles. Approximately how far is Tom’s house from the beach on the map?
Tom's house is approximately 1.08 inches away from the beach on the map. Tom's house is approximately 1.08 inches away from the beach on the map.
Let x represent the distance on the map. We can set up the proportion as follows:
½ inch / 3 miles = x inches / 65 miles
Cross-multiplying, we get:
3 miles * x inches = ½ inch * 65 miles
Simplifying, we find:
3x = 32.5
Dividing both sides by 3, we get:
x = 10.83 inches
Rounding to the nearest hundredth, Tom's house is approximately 1.08 inches away from the beach on the map. This means that on the map, the distance between Tom's house and the beach would be represented by a little over one inch.

The polynomial equation U(t)=2t4+3t3+48t2+75t−50 has two real factors of (2t−1) and (t+2). Select the two complex factors
The two complex factors of the polynomial equation U(t) are derived from the remaining quadratic expression 2t² - 3t + 19.
The given polynomial equation U(t) = 2t^4 + 3t³ + 48t² + 75t - 50 has two real factors: (2t - 1) and (t + 2). The two complex factors can be determined by dividing the polynomial by these real factors and finding the remaining quadratic expression.
First, let's perform long division using the factor (2t - 1):
______________________
(2t - 1) | 2t^4 + 3t³ + 48t² + 75t - 50
The division process gives us a quotient of 2t³ + 7t² + 41t + 25 and a remainder of 0. Now, we can factorize the quotient expression: 2t³ + 7t² + 41t + 25.
Next, let's perform long division using the factor (t + 2):
________________________
(t + 2) | 2t³ + 7t² + 41t + 25
The division process gives us a quotient of 2t² - 3t + 19 and a remainder of 0. Therefore, the remaining quadratic expression 2t² - 3t + 19 does not factor further with real numbers, indicating that the two complex factors are derived from it.

The required simplified expression for the sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.
To write the sum of two algebraic expressions, we need the specific expressions or equations. Since you mentioned using algebra tiles, assuming to simplify an expression using visual representation.
Let's consider an example expression: (x + 3) + (2x - 4).
To simplify this expression using algebra tiles, we can represent x using a green tile, a positive constant term using a yellow tile, and a negative constant term using a red tile. Each x represents one green tile, each positive constant term represents one yellow tile, and each negative constant term represents one red tile.
(x + 3) can be represented as one green tile (x) and three yellow tiles (+3).
(2x - 4) can be represented as two green tiles (2x) and four red tiles (-4).
To find the sum, we can combine like terms by putting the tiles together. We combine the green tiles and the yellow tiles separately:
Green tiles: x + 2x = 3x (Three green tiles)
Yellow tiles: +3 - 4 = -1 (One yellow tile and four red tiles)
Therefore, the simplified expression for the sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.
Using algebra tiles, we can visually represent and manipulate expressions, helping in understand the concepts of combining like terms and simplifying expressions.

The cheasebirger is three times the price of the fries and the drink and the fries were the same price. if the entire meal was $12.50 what was the price for each item?
Let's break down the information given to solve the problem. We'll denote the price of the fries as "f," the price of the drink as "d," and the price of the cheeseburger as "c."
From the given information, we can deduce two equations:
c = 3(f + d) (The cheeseburger is three times the combined price of the fries and the drink.)
f + d = x (The price of the fries and drink combined is denoted as "x".)
We also know that the entire meal costs $12.50, so we can form a third equation:
3. c + f + d = 12.50
Now, let's substitute the value of x from equation 2 into equation 1:
c = 3x
Substituting the value of c from equation 1 into equation 3, we have:
3x + x = 12.50
4x = 12.50
x = 3.125
So, the price of the fries and drink combined (x) is $3.125. Since the price of the fries and the drink are the same, each item costs $3.125/2 = $1.5625.
Therefore, the price for the cheeseburger (c) is 3 times the combined price of the fries and drink, which is 3 * $3.125 = $9.375.
In summary, the price for each item is as follows:
Fries and drink: $1.5625 each
Cheeseburger: $9.375

Albert measured a house and its lot and made a scale drawing.
The house's driveway is 3 inches wide in the drawing. The actual
driveway is 15 feet wide.
The width of the driveway in the drawing is 3 inches and the actual width of the driveway is 15 feet.
Scale factor is a term used in mathematics and geometry to describe the ratio of the lengths or measurements of corresponding sides or dimensions of similar figures or objects. It provides a proportional relationship between the sizes of two similar figures.
Understanding the scale factor is important for proportional resizing, creating accurate representations of objects or figures, and maintaining consistent relationships between corresponding measurements. It allows for precise scaling and comparison of similar figures.
Given that the width of the driveway in the drawing is 3 inches and the actual width of the driveway is 15 feet.
Therefore, we need to determine the scale factor that can help us find the actual length of the driveway from the drawing.
We know that,
scale factor = Actual length / Length in the drawing
Scale factor = 15 feet / (3/12) feet
Scale factor = 15 / (1/4)Scale factor = 60
Therefore, the scale factor is 60.
This means that one unit of length in the drawing represents 60 units of length in the actual object. So, if the width of the driveway is 3 inches in the drawing, the actual width can be found by multiplying it with the scale factor.
Actual width of the driveway = 3 inches × 60Actual width of the driveway = 180 inches or 15 feet
Therefore, the actual width of the driveway is 15 feet.

What are the x-intercepts for the function f(x) = x2 2x – 15?.
The x-intercepts for the function f(x) = x^2 + 2x - 15 are x = -5 and x = 3.
To find the x-intercepts, we set the function equal to zero and solve for x. In this case, we have the equation:
x^2 + 2x - 15 = 0
To factor this quadratic equation, we look for two numbers that multiply to -15 and add up to 2. The numbers that satisfy this condition are -5 and 3.
Therefore, the factored form of the equation is:
(x - 3)(x + 5) = 0
Setting each factor equal to zero, we find the x-intercepts:
x - 3 = 0 --> x = 3
x + 5 = 0 --> x = -5
Hence, the x-intercepts for the function f(x) = x^2 + 2x - 15 are x = -5 and x = 3.

The swimming pool is open when the high temperature is higher than 20 c. Lainey tried to swim on Monday and Thursday (which was 3 days later). The pool was open on Monday, but it was closed on Thursday. The high temperature was 30 c.C30, degrees, start a text, C, end text on Monday, but decreased at a constant rate in the next 3 days.
Answer: Let's assume the high temperature on Monday is represented by C30 (30 degrees Celsius). Since the pool is open when the high temperature is higher than 20 degrees Celsius, the pool was open on Monday.
However, over the next three days, the high temperature decreased at a constant rate. Let's denote the rate of decrease as "r" (in degrees Celsius per day).
Since the high temperature on Monday was C30, we can calculate the high temperature on Thursday by subtracting the decrease in temperature over three days:
High temperature on Thursday = C30 - 3r
We know that the pool was closed on Thursday, so the high temperature on Thursday must have been lower than or equal to 20 degrees Celsius.
Therefore, we can set up the inequality:
C30 - 3r ≤ 20
Now, we can solve this inequality to find the range of values for the rate of decrease (r) that would satisfy the condition:
C30 - 3r ≤ 20
Substituting C30 = 30, we have:
30 - 3r ≤ 20
Subtracting 30 from both sides:
-3r ≤ -10
Dividing by -3 (and reversing the inequality since we are dividing by a negative number):
r ≥ 10/3
Therefore, for the pool to be closed on Thursday, the rate of decrease in temperature (r) must be greater than or equal to 10/3 degrees Celsius per day.
