Question 1 of 5
How many milliliters are in 0.5 liters?
Correct Answer: C
Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1,000 milliliters. Therefore, to find out how many milliliters are in 0.5 liters, you multiply 0.5 by 1,000, which gives you 500 milliliters. Hence, the correct answer is 500 milliliters. Remember, when converting between units, you must use the correct conversion factor to ensure the accuracy of your calculations.

Question 2 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.
Question 3 of 5
After spending 80% of her $60, Lana is left with how much money when she invests the remaining amount and earns an 80% profit?
Correct Answer: A
Rationale: After spending 80% of $60, Lana spends $48, leaving her with $12. When she invests this remaining amount and earns an 80% profit on $12, it amounts to $21.60 ($12 + 80% of $12 = $12 + $9.60 = $21.60). Therefore, Lana now has $21.60 in total.
Question 4 of 5
What is the equivalent weight in pounds of 50 kg? (1 kg = 2.2 lb)
Correct Answer: A
Rationale: To convert kilograms to pounds, you multiply by the conversion factor 2.2 (1 kg = 2.2 lb). Therefore, 50 kg * 2.2 lb/kg = 110 lb. The correct answer is A because 50 kg is equivalent to 110 lb when using the conversion factor.
Question 5 of 5
What is the area of a circle with a diameter of 16 inches in terms of pi (π)?
Correct Answer: B
Rationale: To calculate the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is given as 16 inches, the radius (r) is half of that, which is 8 inches. By substituting r = 8 into the formula, you calculate the area as A = π(8)� = 64π square inches. Therefore, the correct answer is 64π in squared (Choice B). This calculation is derived from the concept of the radius being half of the diameter in a circle formula.
