Question

The variable z is inversely proportional to x. When x is 12, z has the value 1.5833333333333. What is the value of z when x= 18?

Answer 1

Z=1.055

Explanation:

Z is inversely proportional to X:
`Z=(K)/(X)` Where K is a constant

X=18, Z=1.583333333333 we can find K value

K=Z*X =1.58333333333*12= 19

So, Using X=18 We have the following

`Z=(19)/(18)`= 1.055
