I went through and solved this problem plenty of times...and my answer always comes out to 5/6..however, that's not even one of the choices. One of the choices is 6/5 though...

maybe I'm doing somehting wrong

1. Find the missing value. Y is directly proportional to x and inversely proportional to the square of z. Y = 20 when x = 50 and z = 5. Find y when x = 3 and z = 6

5 answers

y = kx/z^2

20 = k(50)/(25)
k = 10

Now use k to find y:

y = (10)(3)/36 = 30/36 = 5/6

Gotta go with your answer, guy.

Thanks.
...and I'm a girl

sorry; too mysterious

It's cool, that's the point

I go with 5/6 also.
