Directions: Read the following questions and write the letter of the correct answer on
your activity notebook. (Use k as the constant of variation)


1. If varies jointly as and , find if = 3, = 6 = 9.

A. = 162

B. = 163

C. = 164

D. = 165


2. A variable varies directly as the square root of a variable , and equals 6 when = 4.
Find when = 25.

A. = 9

B. = 11

C. = 13

D. = 15


3. If varies jointly as and . If = 2 when = 3 and = 11, then find .

A. = 66

B. = 77

C. = 88

D. = 99


4. If varies directly as and inversely as , and = 4 ℎ = 2 = 6, find when
= 4 = 8.

A. = 2

B. = 4

C. = 6

D. 8


5. The variable varies directly as , and = 80 when = 16. Find when = 100.

A. = 10

B. = 20

C. = 40

D. = 70
