HESI A2 Math Practice Exam

Correct Answer: A

Rationale: To find the number that 44 is 25% of, we divide 44 by 0.25 (which is 25% expressed as a decimal). 44 / 0.25 = 176. Therefore, 44 is equal to 25% of 176. Option A (176) is the correct answer. Option B (150), C (180), and D (120) are incorrect as they do not result in 44 when multiplied by 0.25.

Correct Answer: C

Rationale: The correct answer is C: $17. Rationale: 1. Mr. Brown bought 5 cheeseburgers, 3 drinks, and 4 fries, totaling 12 items. 2. Each item costs $30, so the total cost before tax is $30 x 12 = $360. 3. A 5% tax is added to the total cost: $360 x 0.05 = $18. 4. Adding the tax to the total cost gives us $360 + $18 = $378. 5. Therefore, the total cost of dinner for Mr. Brown is $378. 6. Among the choices, $17 is the closest amount to the calculated total cost of $378, making it the correct answer. Summary: A: $16 - Incorrect, as it is lower than the calculated total cost. B: $16.90 - Incorrect, as it is lower than the calculated total cost. C: $17 - Correct, as it is

Correct Answer: C

Rationale: To convert 5 gallons to quarts, we know that 1 gallon = 4 quarts. So, 5 gallons = 5 x 4 = 20 quarts. Since she needs quart jars, Jan will need to buy 20 quart jars to can her 5 gallons of homemade tomatoes. Choices A, B, and D are incorrect because they do not correctly convert gallons to quarts. Choice A (10) is half of the correct answer, choice B (15) is three-quarters, and choice D (25) is more than the actual amount needed.

Correct Answer: C

Rationale: To convert 2 teaspoons to milliliters, we need to know that 1 teaspoon is approximately 4.93 milliliters. Therefore, 2 teaspoons would be 2 * 4.93 = 9.86 milliliters. The correct answer is C (9.86 milliliters). Choice A (4.3 milliliters) is incorrect because it is too low based on the conversion factor. Choice B (9 milliliters) is close but not accurate, as the exact conversion gives 9.86 milliliters. Choice D (4 milliliters) is also incorrect as it is lower than the actual conversion.
