Question

R varies indirectly as h and r is equal to 5 find r when h equal to 12

Answer 1

If R varies inversely as h, this can be represented by the equation: R = k/h, where k is a constant.

Given that R = 5, we can plug in this value and the given value of h = 12 into the equation to solve for k:

5 = k/12

To solve for k, we can multiply both sides of the equation by 12:

12 * 5 = k

k = 60

Now that we know the value of k, we can substitute it back into the equation to find the value of r when h = 12:

R = k/h
R = 60/12
R = 5

Therefore, when h = 12, r = 5.
