HESI A2 Math Practice Test 2023

Correct Answer: B

Rationale: To find the perimeter of the table, we add the lengths of all four sides. Since opposite sides are equal, we have two pairs of sides with lengths 75cm and 50cm each. Therefore, the perimeter is 2(75cm) + 2(50cm) = 150cm. Choice A is incorrect because it only considers one pair of sides. Choice C is incorrect as it adds all sides together without considering the pairs. Choice D is incorrect as it only considers one side length.

Correct Answer: C

Rationale: To subtract 20.7 from 13.4, we need to borrow since we cannot subtract a larger number from a smaller one. So, borrowing from the tens place, we get 13.4 as 12.14. Then, subtracting 12.14 from 20.7 gives us 8.56. Rounding off to one decimal place, we get 8.6, which is closest to choice C: 7.3. Hence, the correct answer is C. Choice A, 7.1, is incorrect as it is not close to the calculated result. Choices B and D are also incorrect as they are not close to the rounded off result.

Correct Answer: B

Rationale: To find 80% of 55, you multiply 55 by 0.8 (which is the decimal equivalent of 80%). So, 55 * 0.8 = 44. Therefore, the correct answer is B (44). Choice A (40) is incorrect as it represents 80% of 50, not 55. Choices C (39) and D (45) are also incorrect calculations.

Correct Answer: A

Rationale: The correct answer is A: 5.3 hours. To calculate the total time taken, add the time taken for each set of 6 miles: 1 hour + 1.2 hours + 1.5 hours + 1.6 hours = 5.3 hours. This is the total time taken by the female to complete the 24-mile course. Choice B (4.5 hours) is incorrect because it does not account for the increasing time taken for each set of 6 miles. Choice C (6 hours) is incorrect as it assumes each set of 6 miles took the same amount of time, which is not the case. Choice D (7 hours) is incorrect as it overestimates the total time taken.

Correct Answer: C

Rationale: To convert quarts to ounces, we know that 1 quart is equal to 32 ounces. Therefore, to find out how many ounces are in 4.5 quarts, we multiply 4.5 by 32, which equals 144 ounces. So, the correct answer is C (144 ounces). Incorrect Choices: A: 120 ounces - This is incorrect because it does not account for the correct conversion factor of 1 quart to 32 ounces. B: 120 ounces - Same as choice A, incorrect conversion factor used. D: 128 ounces - This is incorrect as it is not the correct result of multiplying 4.5 quarts by 32 ounces per quart.
