HESI A2 Math Practice Test 2023 Questions
Question 1 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 2 of 5
How many ounces are in 4.5 quarts?
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.
Question 3 of 5
What is 80% of 55?
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.
Question 4 of 5
How many grams are in 5 kilograms?
Correct Answer: C
Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, to convert 5 kilograms to grams, you would do: 5 kg x 1000 = 5000 grams. Choice C (5,000 grams) is the correct answer. Choice A (50,000 grams) and choice D (50,000 grams) are incorrect because they do not correctly convert the kilograms to grams. Choice B (500 grams) is incorrect because it represents the grams equivalent of 0.5 kilograms, not 5 kilograms.
Question 5 of 5
Imaginary unit multiples are used to represent numbers that cannot be obtained on the number line. Which of the following is equivalent to 5i?
Correct Answer: C
Rationale: Rationale: To find an equivalent expression for 5i, we can rewrite it as 5√-1. This is because i represents √-1. Therefore, 5i is equivalent to 5 times the imaginary unit, which simplifies to 5√-1. Choice A is incorrect as it represents the negative of 5 and not an imaginary unit. Choice B, i^5, is incorrect as it represents i raised to the power of 5 and not the equivalent of 5i. Choice D, 1/5i, is incorrect as it represents the reciprocal of 5i and not the equivalent value itself.
