HESI A2 Math Practice Exam

Correct Answer: A

Rationale: To find the total days off work, we add Bill's remaining vacation days (5.5) and sick days (3.25). 5.5 + 3.25 = 8.75 Therefore, Bill will have 8.75 days off work if he uses all of his remaining vacation and sick days. Choice A (8.75) is correct because it accurately represents the total days off. Choices B, C, and D are incorrect as they do not correctly calculate the total days off based on the given information.

Correct Answer: B

Rationale: To calculate the percentage increase, subtract the initial price ($9.00) from the final price ($10.00) to get the increase ($1.00). Then, divide the increase by the initial price ($1.00 / $9.00 = 0.1111). Convert the result to a percentage by multiplying by 100, giving 11.11%. Choice B (11.11%) is correct. Choice A (5%) is incorrect because the increase is $1.00, not $0.45. Choice C (20%) and Choice D (25%) are also incorrect as they do not accurately reflect the calculated percentage increase of 11.11%.

Correct Answer: C

Rationale: To calculate the total area to paint, we need to find the surface area of the walls and the floor separately. The surface area of the walls is 2*(8+5)*2 = 36 sq m. The floor area is 8*5 = 40 sq m. Adding these together gives 36 + 40 = 76 sq m. Since one can of paint covers 10 sq m, we need 76/10 = 7.6 cans of paint. Rounding up to the nearest whole number, we need 8 cans of paint, which is equivalent to 88 sq m. Therefore, the correct answer is C (88 sq m). Choice A (56 sq m) is incorrect as it does not consider the surface area of the floor. Choice B (72 sq m) is incorrect as it miscalculates the total area to paint. Choice D (104 sq m) is incorrect as it overestimates the amount of paint needed.

Correct Answer: C

Rationale: The correct answer is C (Early afternoon to bedtime) because working from 1300 to 2000 corresponds to the time frame of early afternoon to bedtime. 1300 is 1:00 PM in the afternoon, and 2000 is 8:00 PM in the evening. This aligns with the early afternoon to evening shift. Incorrect choices: A: Early morning to early afternoon - This is incorrect as the healthcare professional's shift starts in the afternoon, not the early morning. B: Lunchtime to midnight - This is incorrect as the shift ends at 8:00 PM, not midnight. D: Midnight to sunrise - This is incorrect as the shift starts in the afternoon, not at midnight.

Correct Answer: B

Rationale: The correct answer is B: MCMVI. Here's the rationale: 1. M represents 1000, CM represents 900, and VI represents 6. 2. Combining these symbols, MCMVI represents 1000 (M) + 900 (CM) + 6 (VI) = 1906. 3. Option A (MCMIV) is incorrect as IV represents 4, not 6. 4. Option C (MDCCCCVI) is incorrect as it uses the subtractive notation excessively (900 + 100 + 100 + 100 + 100 + 5 + 1). 5. Option D (MCMVII) is incorrect as VII represents 7, not 6.
