1. a 20-acre field produces 300 bushels of wheat. let w represent the number of bushels produced by a 50-acre field at the same rate. select the correct statement of the given condition.
a. 20/300 = 50/w
b. 20/w = 50/300
c. 20/300 = w/50
d. 20/50 = w/300
2. w varies inversely as the square of t. if w = 12 when t = 2, find t when w = 27.
a. 27t = 24
b. 27t² = 48
c. 108 = 12t²
d. 12t = 54
3. the pressure p of a compressed gas is inversely proportional to the volume v. if there is 3 pressure of 25 pounds per square inch when the volume of gas 400 cubic inches, find the pressure when the gas is compressed to 200 cubic inches.
a. 200p = 1
b. 25p = 8
c. 400p = 5000
d. none of the above
4. an experimental drug is given to 100 people with a certain ailment. fifty-three of these people were cu
Answers: 3
1. Using Acre/Bushels:
20/300 = 50/W
A
2. Using W/t²
W/t² = 12/2² = 12/4
12/4 = 27/t²
12t² = 108
C
3. Using pressure/volume
P/V = 25/400
25/400 = P/200
400P = 5000
C
