HESI A2 Math Practice Test 2023 Questions
Question 1 of 5
How many ounces are in 2.5 gallons?
Correct Answer: C
Rationale: To convert gallons to ounces, we know that 1 gallon equals 128 ounces. Therefore, to find out how many ounces are in 2.5 gallons, we multiply 2.5 by 128. 2.5 * 128 = 320 ounces. Therefore, the correct answer is C: 320 ounces. Other choices are incorrect because they do not correctly calculate the conversion from gallons to ounces. A, B, and D do not consider the correct conversion factor of 128 ounces per gallon.
Question 2 of 5
The metric system of measurement was developed in France during Napoleon's reign. It is based on what multiplication factor?
Correct Answer: C
Rationale: The correct answer is C: 10. The metric system is based on multiples of 10, making conversions between units easy and logical. This factor allows for a systematic and uniform system of measurement, which is essential for scientific accuracy and global standardization. Choices A, B, and D are incorrect because the metric system is not based on the length of Napoleon's forearm, the number 2, or the atomic weight of helium. These options do not align with the foundational principles of the metric system, which is built on the decimal system for simplicity and consistency.
Question 3 of 5
A female ran a 24-mile course. Her first 6 miles took 1 hour, the second set of 6 miles took 1.2 hours, the third set of 6 miles took 1.5 hours, and the fourth set of 6 miles took 1.6 hours. How long did it take her to complete the course?
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.
Question 4 of 5
Subtract 32 divided by 8\9.
Correct Answer: A
Rationale: To subtract 32 divided by 8\9, first divide 32 by 8 to get 4. Then divide 4 by 9, which equals 4\9. Subtracting 4\9 from 32 gives 36, which is the correct answer (A). Choice B (32) is incorrect as it only divides 32 by 8, not considering the second division by 9. Choices C (40) and D (44) are incorrect as they do not follow the correct division and subtraction steps.
Question 5 of 5
How many milligrams are in 3.4 grams?
Correct Answer: B
Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in 1 gram. Therefore, 3.4 grams x 1000 = 3400 mg. Choice B is correct because it correctly converts grams to milligrams. Choices A, C, and D are incorrect as they do not correctly apply the conversion factor from grams to milligrams. Option A is off by a factor of 10, option C is off by a factor of 100, and option D is off by a factor of 10.
