Question 1 of 5
Four friends are sharing a pizza. One friend eats half of the pizza. The other three friends equally divide the rest among themselves. What portion of the pizza did each of the other three friends receive?
Correct Answer: D
Rationale: After one friend eats half of the pizza, half of the pizza remains to be divided among the other three friends. Dividing this remaining half equally among three friends means each friend receives 1/6 of the pizza (1/2 � 3 = 1/6). Therefore, each of the other three friends receives 1/6 of the pizza.

Question 2 of 5
If X represents the width of a rectangle and the length is four less than three times the width, which of the following expressions represents the length of the rectangle in terms of X?
Correct Answer: A
Rationale: To determine the expression for the length of the rectangle in terms of X, we need to consider that the length is four less than three times the width. This can be mathematically represented as 3 times X minus 4, which simplifies to 3x - 4 (choice A). Therefore, choice A correctly represents the length of the rectangle in terms of X, making it the correct answer.
Question 3 of 5
When a person increases cycling speed, the rate of calories burned, distance traveled, and energy expended also increase. Which of the following is the independent variable?
Correct Answer: A
Rationale: In the context of this scenario, the independent variable is the factor that is deliberately altered or controlled to observe its impact on other variables. When a person adjusts their cycling speed, it directly influences the rate of calories burned, distance traveled, and energy expended. Speed is the independent variable because it is manipulated to study its effects on the dependent variables - calories burned, distance traveled, and energy expended. Therefore, the correct answer is 'Speed.'
Question 4 of 5
What is the equivalent weight of 50 kg in pounds (1 kg = 2.2 lb)?
Correct Answer: A
Rationale: To convert 50 kg to pounds, we need to multiply by the conversion factor 2.2 lb/kg. Therefore, 50 kg * 2.2 lb/kg = 110 lb. The correct answer is A, which is 110 lb. The provided conversion factor (1 kg = 2.2 lb) is used to convert kilograms to pounds. By multiplying 50 kg by the conversion factor, we get the equivalent weight in pounds, which is 110 lb.
Question 5 of 5
One gallon of cleaning solution requires 6 oz of ammonia. If the maintenance department needs 120 gallons of solution to clean all the floors, how much ammonia is needed?
Correct Answer: C
Rationale: To calculate the total amount of ammonia needed, you must multiply the amount of ammonia required for one gallon of solution by the total number of gallons needed. With 6 oz of ammonia per gallon, multiplying 6 oz by 120 gallons gives you a total of 720 oz of ammonia needed. Therefore, 720 oz of ammonia are required to clean all the floors.
