Question

If R variably indirectly as H and R=5, when H=12
(a) find R when H=20
(b) find H, when R=45

Answer 1

To find R when H=20, we need to find the relationship between R and H first. From the given information, we can write the equation as:

R = 5H

(a) When H=12, we can substitute it into the equation to find R:

R = 5(12)
R = 60

So, when H=20, we can substitute it into the equation to find R:

R = 5(20)
R = 100

Therefore, when H=20, R=100.

(b) To find H when R=45, we can rearrange the equation:

R = 5H
H = R/5

Substituting R=45 into the equation:

H = 45/5
H = 9

So, when R=45, H=9.
