The metric system of measurement was developed in France during Napoleon's reign. It is based on what multiplication factor?

  • A. The length of Napoleon's forearm
  • B. 2
  • C. 10
  • D. Atomic weight of helium
Correct Answer: C

Rationale: The metric system is based on powers of 10, making calculations and conversions easier because each unit increases or decreases by a factor of 10. This factor allows for a simple and consistent way to move between different units within the system. Choice A, 'The length of Napoleon's forearm' is incorrect as the metric system is not based on a physical attribute but on a standardized mathematical factor. Choice B, '2,' and Choice D, 'Atomic weight of helium,' are also incorrect as they do not align with the foundational principle of the metric system being based on powers of 10.

Subtract 12 1/8 - 9 1/2.

  • A. 2 5/8
  • B. 3 1/8
  • C. 4 1/2
  • D. 4 2/3
Correct Answer: A

Rationale: To subtract mixed numbers, first subtract the fractions: 1/8 - 1/2 = -3/8. Then, subtract the whole numbers: 12 - 9 = 3. Combine the whole number and fraction: 3 - 3/8 = 2 5/8. Therefore, the correct answer is A. Choice B is incorrect because it does not reflect the correct subtraction of the fractions. Choices C and D are incorrect as they do not result from the correct subtraction process outlined above.

How many inches are in 1.5 yards?

  • A. 54 inches
  • B. 60 inches
  • C. 72 inches
  • D. 84 inches
Correct Answer: A

Rationale: To convert yards to inches, multiply the number of yards by 36 (since there are 36 inches in a yard). 1.5 yards 36 inches/yard = 54 inches. Therefore, the correct answer is 54 inches. Choice B, 60 inches, is incorrect as it incorrectly assumes that there are 40 inches in a yard. Choice C, 72 inches, is incorrect as it multiplies 1.5 by 48, which is not the correct conversion factor. Choice D, 84 inches, is incorrect as it multiplies 1.5 by 56, which is not the correct conversion factor.

What is 70% of 200?

  • A. 100
  • B. 100
  • C. 200
  • D. 140
Correct Answer: D

Rationale: To find 70% of a number, you multiply the number by 0.70. Therefore, 70% of 200 is calculated as 0.7 200 = 140. Choices A, B, and C are incorrect as they do not represent the correct calculation for finding 70% of 200.

Solve for x: 4x - 8 = 16.

  • A. x = 7
  • B. x = 7
  • C. x = 4
  • D. x = 6
Correct Answer: D

Rationale: To solve the equation 4x - 8 = 16, first, add 8 to both sides to isolate 4x: 4x = 24. Then, divide by 4 to solve for x: x = 6. Therefore, the correct answer is D. Choice A, x = 7, is incorrect as the correct solution is x = 6. Choices B and C are duplicates of choice A and are also incorrect.

How many grams are in 6 kilograms?

  • A. 600 grams
  • B. 6000 grams
  • C. 600 grams
  • D. 60,000 grams
Correct Answer: B

Rationale: There are 1,000 grams in a kilogram. Therefore, to convert kilograms to grams, you need to multiply the number of kilograms by 1,000. In this case, 6 kilograms would be equal to 6 1,000 = 6,000 grams. Choices A, C, and D are incorrect because they do not apply the correct conversion factor from kilograms to grams.
