Question 1 of 5
A seamstress is measuring a model for a new dress. The tape measure is marked in centimeters. The seamstress needs to convert that measurement into inches. If the model's waist measurement is 65.4 centimeters, what is that in inches?
Correct Answer: A
Rationale: To convert centimeters to inches, we use the conversion factor 1 inch = 2.54 centimeters. Therefore, to convert 65.4 centimeters to inches, we divide 65.4 by 2.54. The calculation is 65.4 / 2.54 = 25.74 inches. This is why choice A (25.74) is correct. Choices B, C, and D are incorrect as they do not correctly convert centimeters to inches.
Question 2 of 5
12 is a/an:
Correct Answer: A
Rationale: Step-by-step rationale: 1. An even number is divisible by 2. 2. 12 is divisible by 2 (12 ÷ 2 = 6). 3. Therefore, 12 is an even number (Choice A). Summary: B: Incorrect - Odd numbers are not divisible by 2. C: Incorrect - Prime numbers have only 2 factors. D: Incorrect - Composite numbers have more than two factors.
Question 3 of 5
A hospital day staff consists of 25 registered nurses, 75 unlicensed assistants, five phlebotomists, six receptionists and office staff, and 45 physicians. One summer day the staff was at only 68% strength. How many people were working that day?
Correct Answer: A
Rationale: To calculate the total number of people working that day, we need to find 68% of the total staff. First, calculate 68% of each category: - Registered nurses: 25 * 0.68 = 17 - Unlicensed assistants: 75 * 0.68 = 51 - Phlebotomists: 5 * 0.68 = 3 - Receptionists and office staff: 6 * 0.68 = 4 - Physicians: 45 * 0.68 = 31 Add these numbers together: 17 + 51 + 3 + 4 + 31 = 106 people (Option A). This is the correct answer as it represents 68% of the total staff. Other options are incorrect as they do not accurately represent 68% of the total staff.
Question 4 of 5
Bill has 2.5 vacation days left for the rest of the year and 1.25 sick days left. If Bill uses all of his sick days and his vacation days, how many days will he have off work?
Correct Answer: D
Rationale: To calculate the total days off, add Bill's remaining vacation days (2.5) and sick days (1.25): 2.5 + 1.25 = 3.75 days. Since Bill is using all his sick days and vacation days, he will have 3 full days off work. Therefore, the correct answer is D (4 days). Choices A, B, and C are incorrect as they do not consider the combination of remaining days and assume a different outcome.
Question 5 of 5
Change the following decimal to a percent: 0.09
Correct Answer: A
Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.09 * 100 = 9%. Therefore, the correct answer is A: 9%. Choice B (90%) is incorrect as it would be the result of multiplying by 1000, not 100. Choice C (1%) is incorrect as it would be the result of moving the decimal point two places to the right without multiplying by 100. Choice D (0%) is incorrect as the number is not zero, it's 0.09.
