Question

For the inverse variation equation P=8/V, what is the value of V when P = 1/2?

A) 1/16
B) 1/4
C) 4
D) 16

Answer 1

(D) 16

Step-by-step explanation:

It is given that the inverse variation equation is
`P=8V`.

Now, substituting the value of P=
`(1)/(2)` in the above given equation, we get

⇒
`(1)/(2)=(8)/(V)`

Cross multiplying on both sides,

⇒
`V=\frac{8{*}2}{1}`

⇒
`V=16`

Hence, option D is correct.

Answer 2

Answer:
16

Step-by-step explanation:
We are given the equation:
P =
`(8)/(V)`

We want to find the value of V at P =
`(1)/(2)`

Therefore, all we have to do is substitute with P =
`(1)/(2)` in the above equation and solve for V as follows:
P =
`(8)/(V)`


`(1)/(2)` =
`(8)/(V)`

1 * V = 2 * 8
V = 16

Hope this helps :)
