Question 1 of 5
On a floor plan drawn at a scale of 1:100, the area of a rectangular room is 30 cm². What is the actual area of the room?
Correct Answer: D
Rationale: On a 1:100 scale drawing, each centimeter represents one meter. The area of the room in the scale drawing is 30 cm², which means the actual area is 30 m².
Choice A (30,000 cm²) is incorrect as it doesn't account for the scale conversion.
Choice B (300 m²) is incorrect because it multiplies the scale area directly by 10,000, which is not the correct conversion.
Choice C (3,000 m²) is also incorrect as it applies the scale factor incorrectly.
Extract:
Pernell's scores on her last five chemistry exams were 81, 92, 87, 89, and 94.
Question 2 of 5
What is the median of Pernell's scores (81, 92, 87, 89, and 94)?
Correct Answer: B
Rationale:
To find the median, we first need to arrange the scores in ascending order: 81, 87, 89, 92, 94. Since there are five scores, the middle score would be the third one, which is 89. Hence, the median of Pernell's scores is 89.
Choice A (87) is incorrect because it is the second score in the ordered list, not the middle one.
Choice C (92) and
Choice D (94) are also incorrect as they are not positioned in the middle of the ordered series.

Question 3 of 5
Simplify the following expression: 0.0178 2.401
Correct Answer: B
Rationale: In this question, the correct answer is
B) 0.0427378.
To simplify the expression 0.0178 * 2.401, you multiply the two numbers together. When you multiply 0.0178 by 2.401, you get 0.0427378.
Option
A) 2.0358414 is incorrect because multiplying 0.0178 by 2.401 does not result in this value. Option
C) 0.2341695 and Option
D) 0.348324 are also incorrect for the same reason.
Educationally, this question tests the student's ability to perform basic multiplication of decimal numbers. It is important for students to understand how to multiply decimals accurately to solve math problems correctly. By practicing questions like these, students can improve their arithmetic skills and build a strong foundation for more complex mathematical concepts.
Question 4 of 5
Erma has her eye on two sweaters at her favorite clothing store, but she has been waiting for the store to offer a sale. This week, the store advertises 25% off a second item of equal or lesser value. One sweater is $50, and the other is $44. What will Erma spend?
Correct Answer: C
Rationale: Erma receives a 25% discount on the $44 sweater, which amounts to a $11 discount.
Therefore, she pays $44 - $11 = $33 for this sweater. Adding this discounted price to the $50 sweater, Erma will spend a total of $50 + $33 = $83.
Choice A, $79, is incorrect because it does not include the correct calculation for the discounted sweater.
Choice B, $81, is incorrect as it does not consider the discounts on both sweaters.
Choice D, $85, is incorrect since it overestimates the total amount Erma will spend.
Question 5 of 5
Jerry needs to load four pieces of equipment onto a factory elevator that has a weight limit of 800 pounds. Jerry weighs 200 pounds. What would be the average weight of each item so that the elevator's weight limit is not exceeded?
Correct Answer: B
Rationale:
To find the average weight per item, subtract Jerry's weight from the elevator's weight limit: 800 - 200 = 600 pounds. Since there are 4 items, divide 600 by 4 to determine that each item should weigh 150 pounds.
Choice A (128 pounds), C (175 pounds), and D (180 pounds) are incorrect as they do not correctly calculate the average weight per item to ensure the elevator's weight limit is not exceeded.
