The Drama Club held a car wash to raise money. The equation y = 15x represents the amount of money y club members made for washing x cars. Identify the constant of proportionality.
Answer:
15
Step-by-step explanation:
Given that:
y = 15x
y = amount of money made by club members made for washing cars
x = number of cars washed
From the equation given ;
Amount made is directly proportional the number of cars washed
Mathematically,
y α x
y = kx
Where k = constant of proportionality
Comparing the given equation with
y = kx
y = 15x
k = 15 = constant of proportionality

Suppose that 2000 is placed in an account that pays 13% interest compounded each year. Assume that no withdrawals are made from the account. Do not do any rounding.
A:Find the amount in the account at the end of 1 year.
B: Find the amount in the account at the end of 2 years.
The amount will be $2260 in the account at the end of 1 year. The amount will be $2553.8 in the account at the end of 2 years.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
A = P(1+r/100)ⁿ
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
As per the question, the given data will be:
p = $2000
r = 13%
t = 1 year
To calculate the amount in the account at the end of 1 year.
A = P(1+r/100)ⁿ
Substitute the values of p,r, and t in the formula,
A = 2000(1 + 13/100)¹
A = 2000(1 + 0.13)¹
A = 2000(1.13)
A = $2260
To calculate the amount in the account at the end of 2 years.
A = 2000(1 + 13/100)²
A = 2000(1 + 0.13)²
A = 2000(1.13)²
A = $2553.8
Thus, the amount will be $2260 in the account at the end of 1 year. The amount will be $2553.8 in the account at the end of 2 years.

Based on the graph, which inequality is correct for a number that is to the left of -4?
a
−7 > −4
b
−6 −4
d
−4 < −9
Answer:
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.
Step-by-step explanation:
Let us analyze all the given inequalities
Given the inequality
[tex]-7\:>-4[/tex]
As -7 can not be greater than -4, so [tex]-7\:>-4[/tex] is false.
Given the inequality
[tex]-8>-4[/tex]
As -8 can not be greater than -4, so [tex]-8>-4[/tex] is false.
Given the inequality
[tex]-4 < -9[/tex]
As -4 can not be lesser than -9, so [tex]-4 < -9[/tex] is false.
Given the inequality
[tex]-6 < -4[/tex]
As -4 is always greater than -6, so [tex]-6 < -4[/tex] will be true.
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.

A rain barrel can hold 72 gallons of water. As it rained last week, water entered the
barrel at a rate of 2 gallons every 6 hours. At this rate, how long will it take the rain
barrel to fill?
(show how you hit the answer if you can)
Answer: Correct me if I’m wrong but I think it’s 216 hours
Step-by-step explanation: every 24 hour you get 8 gallons so do 24 x 10 you get 240 hours and that gets you 80 gallons so you minus 8 gallons so take off 24 hours and you get your answer

D. Vertex at (-7, -9)
I need to get this right so I can bring my grades up so please help!
Answer:
The answer is D. Vertex at (-7,-9).
Step-by-step explanation:
The equation is in vertex form, so you take the opposite of x and the constant stays the same. So, the opposite of 7 is -7 and -9 stays the same.

Mrs. Wally cut a 21 foot long ribbon into four equal lengths. How many feet long was each length of ribbon
the answer is:
Each equal length of ribbon is 5.25 ft
Step-by-step explanation:
21 divided by 4 is 5.25
To find the number of distributed quantities division operator is used. Each length of ribbon was 5.25 foot long.
What is division ?Division is a mathematical operation used to divide a number into equal parts. When a number is divided by another number, a quotient and remainder is obtained.
Given length of ribbon = 21 foot
Number of parts it has to be divided = 4.
So, to get the length of each part divide the total length by 4.
Thus, the length of each part is 21/4 = 5.25 foot.
Hence, the length Mrs. Wally' s each ribbon is 5.25 foot.

subtract 12 from both sides
60-12=4x+12-12
60-12=4x
48=4x
divide both sides by 4

Pedro makes a base monthly salary of $1500. As a vendor, he must sell $20000 worth of items per month. He also makes a 4% commission on all sales beyond the monthly quota. If Pedro sold $26000 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?
Answer:
$2540
Step-by-step explanation:
Given parameters:
Base salary of Pedro = $1500
Amount of commission on sales = 4%
Sales = $26000
Unknown:
