PAX PAX Mathematics 2 — Questions and Answers
Question 1: What is the area of a rectangle with length 12 cm and width 7 cm?
- 38 cm²
- 84 cm² (Correct answer)
- 96 cm²
- 76 cm²
Correct answer: 84 cm²
Area of a rectangle = length × width = 12 × 7 = 84 cm².
Question 2: A medication is available as 500 mg per 5 mL. How many mL are needed for a 750 mg dose?
- 5 mL
- 6 mL
- 7.5 mL (Correct answer)
- 10 mL
Correct answer: 7.5 mL
Dose ratio: 750 mg ÷ 500 mg × 5 mL = 7.5 mL.
Question 3: Order from least to greatest: 2/3, 0.6, 5/8
- 0.6, 5/8, 2/3 (Correct answer)
- 5/8, 0.6, 2/3
- 2/3, 0.6, 5/8
- 0.6, 2/3, 5/8
Correct answer: 0.6, 5/8, 2/3
Converting: 0.6 = 0.600, 5/8 = 0.625, 2/3 ≈ 0.667; so the order is 0.6, 5/8, 2/3.
Question 4: If a patient's temperature is 100.4°F, what is it in Celsius? (C = (F − 32) × 5/9)
- 36.5°C
- 37.0°C
- 38.0°C (Correct answer)
- 39.0°C
Correct answer: 38.0°C
(100.4 − 32) × 5/9 = 68.4 × 5/9 = 38.0°C.
Question 5: What is the square root of 144?
- 11
- 12 (Correct answer)
- 13
- 14
Correct answer: 12
√144 = 12, because 12 × 12 = 144.
