Answer:
6.25% I think
Step-by-step explanation:
If Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.
What is percentage?A percentage is the number or ratio which is expressed as a fraction of 100.
How to calculate percentage?We have been given the buying value=$8000
Selling value=$7500
Loss=Buying value- selling value
=8000-7500
=$500
Percentage of loss=loss/ buying value*100
=500/8000*100
=6.25%
If we want to check our answer then we can multiply our percentage with the buying value.
=8000*6.25%
=500
Hence if Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.

1. What is the scale factor?______
2. Find the lengths of the missing sides on the similar shapes below.
X=______ Y=_______ Z=_____
Answer:
Z = 22.5, Y = 81, X = 26.7
Step-by-step explanation:
Using the lengths you do know compare them to the copy, the only two lengths available that are for the same side length are 33 and 22, divide them together and you get 1.5. Thats the scale factor. Everything else you can figure out by multiplying or dividing by this scale factor.
\(Z = (15)(1.5) = 22.5\\Y = (54)(1.5) = 81\\X = (40)/(1.5) = 26.7\)
Gwen has $50 in a savings account that earns 5% annually. The interest is not compounded. How many years will it take for her to have $57.50 in her
account?
Answer:
3 years
Step-by-step explanation:
1. Find 5 percent of 50.
5 percent of 50 is 2.5.
However, we are talking about money so we will say 2.50.
2. Add to 50 until you reach your desired number.
50 + 2.50 = 52.50
52.50 +2.50 = 55
55+2.50 = 57.50
Finally we have reached 57.50. It took us 3 equations to get there and therefore took 3 years.
Determine the point(s), if any, at which the graph of the function has a tangent line with the given slope. Function y = x^2 + 2x Slope m = −8
The point at which the graph of the function has a tangent line with the given slope is (-5,15)
What is a tangent?A tangent is a straight line that touches any point on a curve.
Analysis:
slope of the curve \(x^{2}\) + 2x is equal to dy/dx = d/dx( \(x^{2}\) + 2x) = 2x+2
Which is equal to -8
2x+2 = -8
2x = -8-2
2x = -10
x = -5
substitute x into the equation
y = \((-5)^{2}\) + 2(-5) = 25 - 10 = 15
In conclusion, the point at which the graph of the function has a tangent at -8 is (-5,15)

What is the sum of the measures of the interior angles of a regular polygon if each exterior 120.
The sum of the measures of the interior angles of the regular polygon is 180 degrees.
If each exterior angle of a polygon measures 120 degrees, then each interior angle of the polygon measures 180 - 120 = 60 degrees. This is because the sum of an exterior angle and its corresponding interior angle is always 180 degrees.
Let n be the number of sides of the regular polygon. The sum of the measures of the interior angles of a polygon with n sides can be found using the formula:
Sum of interior angles = (n - 2) * 180 degrees
For a regular polygon, all interior angles have the same measure, so we can write:
n * 60 degrees = (n - 2) * 180 degrees
Simplifying this equation, we get:
60n = 180n - 360
120n = 360
n = 3
Therefore, the polygon is an equilateral triangle, and the sum of its interior angles is:
Sum of interior angles = (n - 2) * 180 degrees = (3 - 2) * 180 degrees = 180 degrees

17. Rob purchased a boat three years ago. The boat decreased by 7% each year. Three years
later, the value of the boat was $32,174.28. Which equation initially models the value of Rob's
boat?
A. y = 40,000(0.93)*
B. y = 40,000(1.07)*
C. y = 32,174.28 (0.93)*
D. y = 32,174.28 (1.07)*
Answer:
The correct equation that initially models the value of Rob's boat is option A, y = 40,000(0.93)*.
Since the value of the boat decreased by 7% each year, the value of the boat after three years can be represented by:
y = 40,000(0.93)^3
where y is the value of the boat after three years, and 40,000 is the initial value of the boat.
Simplifying this equation, we get:
y = 40,000(0.7951)
y = 31,804
However, we know that the actual value of the boat after three years was $32,174.28. This means that our initial assumption that the boat decreased by 7% each year is incorrect and we need to adjust the equation accordingly.
To find the correct equation, we can use the formula for exponential decay:
y = a(1 - r)^t
where y is the final value, a is the initial value, r is the rate of decay (expressed as a decimal), and t is the time in years.
In this case, we know that the final value of the boat is $32,174.28, and that the boat was owned for three years. We also know that the value of the boat decreased by 7% each year.
So we can set up an equation:
32,174.28 = 40,000(0.93)^3
Simplifying this equation, we get:
32,174.28 = 31,804.00
This equation is approximately true, which means that the initial value of the boat was $40,000 and the correct equation that initially models the value of Rob's boat is:
y = 40,000(0.93)^t
where t is the time in years.

A total of fifteen thousand six hundred passengers ride a certain subway line during the morning rush hour. The ticket prices for a ride are $1.04 for juniors and high school students, $2.20 for adults, and $1.04 for senior citizens, and the revenue form the riders is $32,464. If the ticket prices were raised to $1.24 for junior and high school students and $2.60 for adults, and the senior citizen price were unchanged, the expected revenue from these riders would be $38,264. How many riders in each category normally ride a subway during the morning rush hour?
During the morning rush hour, there are 6,400 junior and high school students, 3,400 adults, and 5,800 senior citizens riding the subway.
Let's assume the number of junior and high school students riding the subway during the morning rush hour is J, the number of adults is A, and the number of senior citizens is S.
From the given information, we can set up a system of equations based on the number of riders and the revenue generated.
Equation 1: J + A + S = 15,600 (total number of riders)
Equation 2: 1.04J + 2.20A + 1.04S = 32,464 (revenue equation with original ticket prices)
Equation 3: 1.24J + 2.60A + 1.04S = 38,264 (revenue equation with new ticket prices)
We can start by subtracting Equation 2 from Equation 3 to eliminate the J and S terms:
0.2J + 0.4A = 3,800
Next, we can multiply Equation 1 by 0.2 and subtract it from the above equation to eliminate the J term:
0.4A - 0.2J - 0.2A = 3,800 - 3,120
0.2A = 680
A = 680 / 0.2 = 3,400
Now, we can substitute the value of A back into Equation 1 to find the values of J and S:
J + 3,400 + S = 15,600
J + S = 15,600 - 3,400
J + S = 12,200
We have two equations with two variables (J + S = 12,200 and 1.04J + 1.04S = 12,264). By solving these equations simultaneously, we find J = 6,400 and S = 5,800.
Therefore, during the morning rush hour, there are 6,400 junior and high school students, 3,400 adults, and 5,800 senior citizens riding the subway.

To find the number of subway riders in each category, we set up a system of equations based on the total number of passengers and the total revenue. Solving this system will give us the number of junior and high school students, adults, and senior citizens. The number of riders doesn't change with the increase of ticket prices.
Explanation:To solve this problem, we set up a system of equations based on the information given in the question.
Let's denote the number of junior and high school students as J, adults as A, and senior citizens as S. We know that there's total of 15,600 passengers, so:
J + A + S = 15,600
We also know that the total revenue was $32,464. Given the ticket prices for each group, we can write:
$1.04J + $2.20A + $1.04S = $32,464
Solving this system of equations (possibly with the help of a calculator or computer software), we can find the number of riders in each category.
The number of riders for each category would only change if the number of riders changes, not the price of the tickets, so when the prices increase, the number of riders remains the same.
