Question 1 of 5
What is the result of adding 4.934, 7.1, and 9.08?
Correct Answer: A
Rationale: To find the sum of 4.934, 7.1, and 9.08, we add them together: 4.934 + 7.1 + 9.08 = 21.114. Therefore, the correct answer is A, 21.114. Choice B, 21.042, is incorrect as it does not represent the accurate sum of the numbers provided. Choice C, 20.214, is incorrect as it does not account for the correct addition of the given numbers. Choice D, 59.13, is incorrect as it is not the sum of the numbers 4.934, 7.1, and 9.08.
Question 2 of 5
Roger's car gets an average of 25 miles per gallon. If his gas tank holds 16 gallons, how far can he drive on a full tank?
Correct Answer: C
Rationale: To calculate the distance Roger can drive on a full tank, multiply the number of gallons in his tank by the average miles per gallon his car gets. 16 gallons x 25 miles per gallon = 400 miles. Therefore, Roger can drive 400 miles on a full tank. Choice A (41 miles) is incorrect as it does not consider the tank's full capacity. Choice B (100 miles) is incorrect as it does not account for the full tank's capacity and the average miles per gallon. Choice D (320 miles) is incorrect as it miscalculates the total distance based on the given information.
Question 3 of 5
Solve for x: 3:2 :: 24:x
Correct Answer: A
Rationale: To solve the proportion 3:2 :: 24:x, we set up the equation 3/2 = 24/x. Cross multiply to get 3x = 48, then divide by 3 to find x = 16. Therefore, the correct answer is 16. Choice B (12) is incorrect as it does not satisfy the proportion. Choice C (2) is incorrect as it does not match the relationship between the numbers given. Choice D (22) is incorrect as it is not the solution to the proportion equation.

Question 5 of 5
Change the decimal to a percent: 0.64 =
Correct Answer: C
Rationale: To convert a decimal to a percent, multiply by 100. In this case, 0.64 100 = 64%. Therefore, the correct answer is C. Choice A (0.64%) is incorrect as it represents the original decimal value in percentage form. Choice B (6.4%) is incorrect as it incorrectly multiplies the decimal value by 10 instead of 100. Choice D (0.064%) is incorrect as it represents the decimal value as a fraction of 1000 instead of 100.
