HESI A2 Quizlet Math - Nurselytic

Correct Answer: B

Rationale: In this question, the correct answer is
B) 128 oz. This can be explained by the fact that there are 128 ounces in a gallon in the US customary system of measurement. It is important for students to understand this conversion because it is a common unit of measurement used in everyday life, especially when dealing with cooking or understanding fluid volumes.

Option
A) 120 oz is incorrect because it is not the equivalent conversion for ounces in a gallon in the US customary system. Option
C) 100 oz and Option
D) 105 oz are also incorrect as they do not represent the standard conversion for ounces in a gallon.

Educationally, understanding unit conversions like this is crucial for practical applications in various fields such as healthcare, culinary arts, and even everyday tasks like measuring liquids for recipes. It reinforces the importance of knowing basic conversions and units of measurement to ensure accurate and precise calculations in different contexts. Students should practice and master these conversions to build a strong foundation in math and real-world problem-solving.

Correct Answer: C

Rationale:
To determine the pounds of cake that can be made with 40 eggs, divide the total number of eggs by the eggs needed per pound of cake: 40 eggs · 3 eggs/pound = 13 pounds of cake.
Therefore, the correct answer is 13 pounds.
Choice A, 12 pounds, is incorrect because it does not consider the ratio of eggs to cake.
Choice B, 14 pounds, and
Choice D, 15 pounds, are incorrect as they do not reflect the correct calculation based on the given ratio in the question.

Correct Answer: B

Rationale: In this math problem, the correct answer is
B) 12,541.8.
To calculate the result of multiplying 226 by 55.3, you need to use the multiplication operation.

The correct answer is obtained by multiplying 226 by 55.3, which equals 12,541.8. This is the accurate mathematical result of the given multiplication operation.

Now, let's analyze why the other options are incorrect:


A) 12,500: This is incorrect because it is a rounded down value and does not accurately represent the result of the multiplication.


C) 12,600: This is incorrect as it is a rounded up value and does not match the precise calculation of 226 multiplied by 55.3.


D) 12,450: This is also incorrect as it does not reflect the accurate multiplication result obtained by multiplying 226 by 55.3.

Educational context: Understanding multiplication is crucial in various real-life scenarios, including calculations, measurements, and problem-solving. By practicing multiplication problems like this, students can enhance their numeracy skills and develop a deeper understanding of mathematical operations. It also reinforces the importance of precision and attention to detail in mathematical calculations.

Correct Answer: A

Rationale: The correct answer is A: 0.09%.
To convert 0.0009 to a percentage, move the decimal point four places to the right and add a percentage sign.
Therefore, 0.0009 is equal to 0.09%.
Choice B (9%) is incorrect as it represents 0.09 without the decimal point adjustment.
Choice C (0.01%) is incorrect as it represents 0.0009 with one less zero.
Choice D (0.90%) is incorrect as it represents 0.9 not 0.0009.

Correct Answer: B

Rationale:
To earn the same amount that Tim makes in 4 hours, Tim earns $30 per hour, totaling $120 in 4 hours. Joe earns $20 per hour, so to match Tim's earnings in 4 hours, Joe must work 2 hours more than Tim.
Therefore, Joe needs to work 2 hours more than Tim to earn the same amount that Tim makes in 4 hours.

Choices A, C, and D are incorrect as they do not accurately reflect the additional hours Joe needs to work compared to Tim to earn the same amount in 4 hours.
