NM-MSSA Mathematics 2 — Questions and Answers
Question 1: A rectangle has a length of 12 cm and a width of 7 cm. What is its perimeter?
- 38 cm (Correct answer)
- 84 cm
- 19 cm
- 76 cm
Correct answer: 38 cm
Perimeter = 2(length + width) = 2(12 + 7) = 2(19) = 38 cm.
Question 2: Which of the following is equivalent to 3/4?
- 0.34
- 0.75 (Correct answer)
- 0.43
- 0.67
Correct answer: 0.75
3 ÷ 4 = 0.75, so 3/4 is equivalent to 0.75.
Question 3: A store sells apples for $0.50 each. If Maria buys 14 apples, how much does she spend?
- $6.00
- $7.00 (Correct answer)
- $7.50
- $8.00
Correct answer: $7.00
14 × $0.50 = $7.00.
Question 4: What is the value of 5² + 3²?
- 64
- 34 (Correct answer)
- 16
- 58
Correct answer: 34
5² = 25 and 3² = 9, so 25 + 9 = 34.
Question 5: On a number line, which point is closest to zero?
- -5
- 3
- -2 (Correct answer)
- 4
Correct answer: -2
The absolute value of -2 is 2, which is the smallest distance from zero among the choices.
Question 6: A triangle has angles measuring 45°, 90°, and x°. What is x?
- 45° (Correct answer)
- 55°
- 35°
- 60°
Correct answer: 45°
The sum of angles in a triangle is 180°, so x = 180 − 45 − 90 = 45°.
Question 7: If y = 3x − 2 and x = 4, what is y?
- 10 (Correct answer)
- 14
- 12
- 9
Correct answer: 10
y = 3(4) − 2 = 12 − 2 = 10.
