HESI A2 Quizlet Math Questions
Question 1 of 5
Last night at the hospital, 76 babies were born. Of the births, 45% were girls. How many boys were born last night? (Round your numbers to the nearest whole number).
Correct Answer: A
Rationale: When 45% of the babies were girls, it means the remaining 55% were boys. To determine the number of boys, calculate 55% of 76, which equals approximately 41.8, rounding up to 42. Therefore, 42 boys were born last night at the hospital. Choice B, C, and D are incorrect as they do not reflect the accurate calculation of the number of boys born.
Question 2 of 5
In a survey, 120 people were asked if they could swim. If 85% said they could, how many people could swim?
Correct Answer: B
Rationale: To find the number of people who could swim, multiply the total number surveyed by the percentage who said they could swim. In this case, 85% of 120 people is calculated as 0.85 * 120, resulting in 102 people who could swim. Choice A (100) is incorrect because this does not account for the percentage that said they could swim. Choice C (110) is incorrect as it is above the total number surveyed. Choice D (90) is incorrect as it does not consider the percentage who said they could swim.
Question 3 of 5
After the young mother goes shopping and spends $101.85 on groceries, $21.90 at the dry cleaners, and $42.66 at the pet store, she has $200.00 in cash. How much money would she have left after her day of shopping?
Correct Answer: A
Rationale: The correct answer is A, $33.59. To find out how much money she would have left, we need to calculate the total spending by adding the amounts spent at the groceries, dry cleaners, and pet store: $101.85 + $21.90 + $42.66 = $166.41. Subtract the total spending from the initial cash amount to determine the remaining cash: $200.00 - $166.41 = $33.59. Choice B, $29.59, is incorrect as it does not accurately reflect the correct calculation. Choices C and D, $25.59 and $21.59 respectively, are also incorrect as they do not consider the correct total spending amount and subtraction from the initial cash.
Question 4 of 5
How many meters are in 5 kilometers?
Correct Answer: B
Rationale: To convert kilometers to meters, you need to multiply the number of kilometers by 1000 since there are 1000 meters in 1 kilometer. Therefore, 5 kilometers is equal to 5 1000 = 5000 meters. Choice A (1000) is incorrect because it represents the number of meters in 1 kilometer, not 5 kilometers. Choice C (10000) is incorrect as it is the result of multiplying 10 (not 5) by 1000. Choice D (500) is incorrect as it represents half the correct conversion value.
Question 5 of 5
Sarah had 1 quart of milk. How many ounces of milk is that?
Correct Answer: C
Rationale: In this question, the correct answer is C) 32 ounces. To understand this, we need to know the conversion between quarts and ounces. 1 quart is equal to 32 ounces. This conversion is based on the fact that there are 32 fluid ounces in a quart. So, if Sarah had 1 quart of milk, she would have 32 ounces of milk. Now, let's analyze why the other options are incorrect: A) 16 ounces: This is incorrect because 1 quart is equivalent to 32 ounces, not 16 ounces. B) 24 ounces: This is incorrect because, as mentioned earlier, 1 quart is equal to 32 ounces, not 24 ounces. D) 48 ounces: This is incorrect because 1 quart is actually 32 ounces, not 48 ounces. In an educational context, understanding basic unit conversions like quarts to ounces is essential for everyday tasks like cooking and measurements. This question assesses the student's ability to apply this conversion factor accurately. It also reinforces the importance of knowing common measurement conversions in real-life situations.
