Answer:
A certain shade of pink us created by adding 3 cups of red paint to 7 cups of white paint
Step-by-step explanation:
Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.
To make color pink,
for every 3 cups of red , we need 7 cups of white.
Let 'r' be the cups of red required
let 'w' be the cups of white required
so , as per the question
for 3 r we need = 7 w
r = 7/3 w
so, 7/3 is constant of proportionality

We are told that Carrie borrows $960 interest free to pay for a car repair. She will repay $120 monthly until the loan is paid off and we are asked to find how many months will it take Carrie to pay off the loan.
In order to find out the number of months to pay off the loan we will divide total amount borrowed by monthly loan installment.
Therefore, Carrie have to pay $120 for 8 months to payoff the loan.
Answer:
Step-by-step explanation:
To calculate the 99th percentile you must order scores from least to greatest, and the one that occupies the position that corresponds to 99% of n-scores is the 99th percentile.
The 99th percentile of a set of observations ( in this case, exam scores) is a value such that 99% of the observations are less than or equal to him and the remaining 1% is greater than or equal to him.
If he is now in the 84% is because there are some people that took the exam in February that are better than him, they had better scores and then, 84% of the observations are less than or equal to him and the remaining 16% is greater than or equal to him.
Before there were only 1% scores that were better than his or her score. Now, there are 16% scores that are better, then people got better scores in the February exam, compared to your friend's score.
We know that they are using 7500 gallons of fuel for 1500 miles
we can do 7500 / 1500 = 5
Meaning that for every 5 gallons of fuel they travel 1 mile
