150

Step-by-step explanation:

Answer 2

Answer:6/25

Step-by-step explanation:

Y varies inversely as x²

Y =k/x²

Y= 6, x = 30

Substitute the value of y and x

6 = k/30²

Make k the subject of the formula

k = 6/900

k =1/150

The equation connecting Y and x is

Y = x²/150

When x = 6

Y= 6²/150

Y= 36/150

Y= 6/25
