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
How many meters are in 3 kilometers?
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.
Question 3 of 5
What is 28% of 100?
Correct Answer: A
Rationale: To find 28% of 100, you multiply 100 by 0.28 (28% as a decimal). So, 100 x 0.28 = 28. Therefore, the correct answer is A: 28. Option B (20) is incorrect because it represents 20%, not 28%. Option C (25) is incorrect as it is not the result of calculating 28% of 100. Option D (30) is also incorrect as it represents 30%, not 28% of 100.
Question 4 of 5
In a local baseball team, 4 players, which represent 5% of the team, have long hair, and the rest have short hair. How many short-haired players are there on the team?
Correct Answer: C
Rationale: To solve this problem, we first find the total number of players on the team by setting up a proportion: 4 players represent 5%, so 1% is equal to 0.8 players. Thus, the total number of players is 4 divided by 0.05, which equals 80 players. Since 4 players have long hair, there are 80 - 4 = 76 players with short hair. The correct answer is C. Option A, B, and D are incorrect because they do not align with the calculated total number of players on the team.
Question 5 of 5
What percentage of 40 is 8?
Correct Answer: C
Rationale: To find the percentage of 8 in 40, divide 8 by 40 and multiply by 100. (8/40) * 100 = 20%. Therefore, the correct answer is C (10%). Choice A (20%) is incorrect as it represents the opposite relationship. Choices B (15%) and D (25%) are also incorrect as they do not reflect the accurate calculation based on the given values.
