HESI A2 Quizlet Math Questions
Question 1 of 5
How many kilometers is equivalent to 200 meters?
Correct Answer: D
Rationale: To convert meters to kilometers, we need to divide by 1000 since 1 kilometer is equal to 1000 meters. Therefore, 200 meters is equal to 200/1000 = 0.2 kilometers. So, the correct answer is D: 0.2 kilometers. Other choices are incorrect because they do not follow the correct conversion factor. A: 50 km, B: 20 km, and C: 12 km are all much larger values than the correct answer of 0.2 km.
Question 2 of 5
If y = 4 and x = 3, solve y x�
Correct Answer: B
Rationale: Failed to generate a rationale after 5 retries.
Question 3 of 5
What is the least common multiple (LCM) of 4 and 6?
Correct Answer: A
Rationale: To find the LCM of 4 and 6, identify the prime factors of each number: 4 = 2^2 and 6 = 2 * 3. The LCM includes all prime factors with the highest powers, so LCM(4, 6) = 2^2 * 3 = 12. Therefore, the correct answer is A (24), as it is the product of the prime factors 2^2 and 3, which is the least common multiple of 4 and 6. Choices B, C, and D are incorrect because they do not represent the correct combination of prime factors for the LCM of 4 and 6.
Question 4 of 5
When a die is rolled, what is the probability of rolling an odd number?
Correct Answer: D
Rationale: The correct answer is D (50%). A die has 6 sides with numbers 1 to 6. There are 3 odd numbers (1, 3, 5) out of the total 6 numbers. Therefore, the probability of rolling an odd number is 3/6, which simplifies to 1/2 or 50%. Choice A (16.67%) is incorrect because it represents the probability of rolling a specific odd number (1 out of 6 options) rather than any odd number. Choice B (33.33%) is incorrect as it assumes the die has only 3 sides, each representing an odd number. Choice C (75%) is incorrect as it represents the probability of rolling an odd number as if there are only odd numbers on the die.
Question 5 of 5
What is the result of multiplying 10 by 5?
Correct Answer: B
Rationale: To find the result of multiplying 10 by 5, we simply perform the operation 10 x 5, which equals 50. This is because multiplication is a repeated addition, so 10 multiplied by 5 is the same as adding 10 together 5 times. Therefore, the correct answer is B. Choice A (65) is incorrect as it is the result of adding 10 and 5, not multiplying. Choice C (45) and D (55) are incorrect as they are not the result of multiplying 10 by 5.
