West B Test Mathematics 2 — Questions and Answers
Question 1: A student earns $12.50 per hour and works 34 hours in a week. Which expression correctly calculates total earnings?
- 12.50 + 34
- 12.50 × 34 (Correct answer)
- 34 ÷ 12.50
- 12.50 − 34
Correct answer: 12.50 × 34
Total earnings = rate × hours = 12.50 × 34 = $425.00.
Question 2: What is the value of 3² + 4²?
- 14
- 25 (Correct answer)
- 49
- 7
Correct answer: 25
3² = 9 and 4² = 16, so 9 + 16 = 25.
Question 3: A rectangle has a length of 15 cm and a width of 8 cm. What is its perimeter?
- 23 cm
- 120 cm
- 46 cm (Correct answer)
- 30 cm
Correct answer: 46 cm
Perimeter = 2(l + w) = 2(15 + 8) = 2(23) = 46 cm.
Question 4: Which of the following is equivalent to 0.75?
- 3/5
- 7/10
- 3/4 (Correct answer)
- 1/4
Correct answer: 3/4
0.75 = 75/100 = 3/4 when reduced to lowest terms.
Question 5: If 5x − 3 = 22, what is x?
- 3.8
- 5 (Correct answer)
- 4
- 25
Correct answer: 5
5x = 22 + 3 = 25, so x = 25 ÷ 5 = 5.
Question 6: A triangle has angles measuring 55° and 80°. What is the measure of the third angle?
- 45° (Correct answer)
- 135°
- 25°
- 75°
Correct answer: 45°
The three angles of a triangle sum to 180°, so the third angle = 180 − 55 − 80 = 45°.
Question 7: Which number is NOT a prime number?
- 17
- 23
- 51 (Correct answer)
- 29
Correct answer: 51
51 = 3 × 17, so it has factors other than 1 and itself and is not prime.
