If R is inversely proportional to S and r=15 when S =12 what is the value of S when R =60

Step-by-step explanation:

The variation above is written as

Where k is the constant of variation

when R = 15

S = 12

k = R × S

k = 15 × 12

k = 180

So the formula for the variation is

When R = 60

We have

Cross multiply

That's

60S = 180

Divide both sides by 60

S = 3

Hope this helps you

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
