HESI A2 Quizlet Math

Correct Answer: A

Rationale: To convert kilometers to meters, we need to multiply by 1000 since there are 1000 meters in 1 kilometer. Therefore, 3 kilometers x 1000 = 3000 meters. This is why choice A (3000 meters) is correct. Choices B, C, and D are incorrect because they do not follow the conversion factor of 1000 meters in 1 kilometer. Choice B (2000 meters) is too low, choice C (3500 meters) is too high, and choice D (2500 meters) is also too low.

Correct Answer: B

Rationale: To solve the equation 4y - 6 = 14 for y: 1. Add 6 to both sides: 4y = 20 2. Divide by 4 to isolate y: y = 5 Therefore, the correct answer is B. Choice A is incorrect as 4 is not the solution. Choices C and D are also incorrect as they do not satisfy the equation when substituted back in.

Correct Answer: A

Rationale: To convert milliliters to liters, you divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 5000 milliliters divided by 1000 equals 5 liters. Choice A is correct as it accurately converts 5000 milliliters into liters. Choices B, C, and D are incorrect as they do not correctly convert the given milliliters to liters.

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.
