An architect is designing a rectangular room. The room has an area of 225 square feet and a width of 15 feet. What is the length of the room?
- A. 30 feet
- B. 15 feet
- C. 25 feet
- D. 45 feet
Correct Answer: B
Rationale: The formula for the area of a rectangle is: Area = Length Width. To find the length, divide the area by the width: 225 · 15 = 15 feet. Therefore, the correct answer is 15 feet. Choice A (30 feet) is incorrect because it is the product of the area and the width, not the length. Choice C (25 feet) is incorrect as it does not match the result of dividing the area by the width. Choice D (45 feet) is incorrect as it is not the result of the calculation needed to find the length.
Richard wants to make 2.5 batches of sugar cookies. One batch calls for 1.75 cups of sugar. How many cups of sugar will Richard need for 2.5 batches?
- A. 4
- B. 3
- C. 5 cups
- D. 3
Correct Answer: A
Rationale: To calculate how much sugar Richard needs for 2.5 batches, multiply the amount of sugar needed for one batch (1.75 cups) by 2.5:
1.75
2.5
=
4.375
cups
1.752.5=4.375 cups
Since the question is asking for the nearest whole number, 4.375 rounds to 4.
A nurse is reviewing the daily intake and output (I&O) of a patient consuming a clear diet. The drainage bag denotes a total of 1,000 mL for the past 24 hours. The total intake is: 2 8oz cups of coffee, 1 16-oz serving of clear soup, and 1 pint of water consumed throughout the day. How much is the deficit in milliliters?
- A. 440 mL
- B. 500 mL
- C. 480 mL
- D. 300 mL
Correct Answer: A
Rationale: First, convert all fluid intake to milliliters:
2 8-oz cups of coffee = 8 2 30 = 480 mL
1 16-oz serving of clear soup = 16 30 = 480 mL
1 pint of water = 16 30 = 480 mL
Total intake = 480 + 480 + 480 = 1440 mL.
The patient produced 1,000 mL, so the deficit is:
1440 mL - 1000 mL = 440 mL.
Therefore, the deficit in milliliters is 440 mL. Choice A is correct. Choices B, C, and D are incorrect as they do not reflect the accurate deficit calculated based on the total intake and output provided in the question.
A kite has a top base of 20cm, a bottom base of 30cm, and two equal side lengths of 15cm. What is its perimeter?
- A. 55cm
- B. 65cm
- C. 70cm
- D. 80cm
Correct Answer: C
Rationale: To find the perimeter of a kite, you need to add the lengths of all its sides. In this case, the perimeter is calculated as the sum of the top base, bottom base, and twice the side length. Therefore, perimeter = top base + bottom base + 2 * side length = 20cm + 30cm + 2 * 15cm = 70cm. Choice A, B, and D are incorrect as they do not consider all sides of the kite in the calculation.
A man is reading. He reads two chapters a day. How long will it take if there are 6 pages per chapter and 798 pages total?
- A. 66 & 1/2
- B. 399
- C. 75 & 1/2
- D. 133
Correct Answer: A
Rationale: First, calculate how many pages the man reads per day. Since he reads two chapters a day and each chapter has 6 pages:
2 chapters/day 6 pages/chapter = 12 pages/day
Now, divide the total number of pages by the number of pages he reads per day:
798 pages · 12 pages/day = 66 1/2 days
Thus, it will take him 66 & 1/2 days to finish the book. Therefore, the correct answer is A. 66 & 1/2. Choices B, C, and D are incorrect as they do not correspond to the correct calculation based on the given information.
