HESI A2 Math Practice Test 2023 Questions
Question 1 of 5
How many milliliters are in 5 pints of water?
Correct Answer: A
Rationale: To convert pints to milliliters, we need to know that 1 pint = 473.176 milliliters. Therefore, 5 pints would be 5 x 473.176 = 2365.88 milliliters. Rounding up, we get approximately 2400 milliliters. This is why choice A (2400 milliliters) is correct. Choices B, C, and D are incorrect because they do not accurately convert pints to milliliters based on the conversion factor provided.
Question 2 of 5
Change 0.004 to a ratio.
Correct Answer: A
Rationale: To change 0.004 to a ratio, we need to express it as a fraction. 0.004 as a fraction is 4/1000, which simplifies to 1/250. Therefore, the correct ratio is 1:250. Choice A is correct because it accurately represents the ratio of 0.004. Choices B, C, and D are incorrect because they do not accurately reflect the equivalent ratio for 0.004.
Question 3 of 5
What is 25% of 200?
Correct Answer: A
Rationale: To find 25% of 200, you multiply 200 by 0.25 (25% is equivalent to 0.25). So, 200 x 0.25 = 50. Therefore, the correct answer is A: 50. Choices B, C, and D are incorrect because: B: 60 - This is not correct as 25% of 200 is 50, not 60. C: 25 - This is incorrect as 25% of 200 is 50, not 25. D: 30 - This is also incorrect as 25% of 200 is 50, not 30.
Question 4 of 5
A car travels 240 miles in 4 hours. What is its speed in miles per hour?
Correct Answer: B
Rationale: To calculate speed, use the formula: speed = distance/time. In this case, the car traveled 240 miles in 4 hours. Therefore, speed = 240 miles / 4 hours = 60 mph. Choice B is correct as it represents the calculated speed accurately. Choice A (50 mph) is too low, Choice C (55 mph) is close but not accurate, and Choice D (75 mph) is too high based on the calculation.
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.
