If y varies inversely as x, and y = 12 when x = 6, what is k, the variation constant? a. 2 b. 72 c. 144 d. 1/3

In this question, it is given that y varies inversely as x . So the equation is

And here k is the proportionality constant .

And when x=6, y=12

So the values of the proportionality constant k is 72 and the correct option is B.

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
