Question

Not sure if I already posted this
If q = 1/2 when r = 1/3 and q varies inversely with r, then find q when r = 6.
A. 1/6
B. 6
C. 1/36
D. 36

Answer 1

(q)(r) = k -> (1/2)(1/3) = k -> k = 1/6

(q)(r) = 1/6 -> (q)(6) = 1/6 -> q = (1/6) / 6

q = 1/36

Answer 2

It's the "inverse proportionality" situation again. When q gets bigger, then r gets smaller.

Answer 3

alright thanks :D
