HESI A2 Quizlet Math

Correct Answer: C

Rationale: The correct answer is C: 6 minutes. When the rat's speed is reduced by 50% due to the backpack, it will take twice as long to finish the maze. Therefore, if the rat initially finished the maze in 3 minutes, it will take 6 minutes with the reduced speed. Summary of other choices: A) 3 minutes - Incorrect because the rat's speed is reduced by 50%, so it will take longer than the initial 3 minutes. B) 4 minutes - Incorrect because the reduction in speed by 50% will result in a doubling of the time taken from the initial 3 minutes, making it 6 minutes. D) 1.5 minutes - Incorrect as the reduction in speed will cause the rat to take longer than the initial 3 minutes, not less time.

Correct Answer: B

Rationale: To calculate the ideal body weight for a man who is 180cm tall: IBW = 50 + 2.3 * (180 - 150) = 50 + 2.3 * 30 = 50 + 69 = 119kg Therefore, the correct answer is B: 71kg. This is because the calculation results in an ideal body weight of 119kg, which corresponds to option B. The other choices (A, C, D) are incorrect as they do not match the calculated value.

Correct Answer: C

Rationale: To convert quarts to gallons, we know that 1 gallon equals 4 quarts. Therefore, to find out how many gallons are in 16 quarts, we divide 16 by 4 which equals 4 gallons. So, the correct answer is C. Explanation of other choices: A: 1 gallon is not the correct answer because 16 quarts is more than 1 gallon. B: 8 gallons is incorrect as it does not align with the conversion factor of 1 gallon per 4 quarts. D: 4.5 gallons is incorrect as it is not the result of dividing 16 quarts by the conversion factor of 4 quarts per gallon.

Correct Answer: A

Rationale: To determine the money left after shopping, subtract the total expenses ($101.85 + $21.90 + $42.66 = $166.41) from the initial cash amount ($200.00). Thus, $200.00 - $166.41 = $33.59 left. Choice A is correct. Choices B, C, and D are incorrect as they do not reflect the accurate remaining amount after subtracting the total expenses from the initial cash.
