Answer:
7/3 is constant of proportionality and, 3/7 of a cup of red paint should be added to 1 cup 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 and, 3/7 of a cup of red paint should be added to 1 cup of white paint.
You already have the answer! ;)
Answer: yes
Step-by-step explanation:
Since $12,000 would be her whole current salary, I would just divide $84,000 by $12,000 because i know 12 can go into 84 evenly.
84,000 ÷ 12,000 = 7
Since it goes in to 84,000 evenly by 7 times, the raise would be 700%.
