NeSA Mathematics 1 — Questions and Answers
Question 1: A student scores 84, 91, 76, 88, and 95 on five NeSA math practice tests. What is the mean score?
- 86.8 (Correct answer)
- 88
- 85.4
- 87.2
Correct answer: 86.8
The mean is calculated by adding all scores (84+91+76+88+95=434) and dividing by 5, giving 86.8.
Question 2: Which property is illustrated by the equation 3 × (4 + 5) = 3 × 4 + 3 × 5?
- Commutative property
- Associative property
- Distributive property (Correct answer)
- Identity property
Correct answer: Distributive property
The distributive property states that multiplying a number by a sum is the same as multiplying by each addend and adding the products.
Question 3: A rectangle has a length of 14 cm and a width of 9 cm. What is its area?
- 126 cm² (Correct answer)
- 46 cm²
- 116 cm²
- 92 cm²
Correct answer: 126 cm²
The area of a rectangle is length × width, so 14 × 9 = 126 cm².
Question 4: Which of the following is equivalent to 3/4?
- 0.34
- 0.75 (Correct answer)
- 0.43
- 0.63
Correct answer: 0.75
To convert 3/4 to a decimal, divide 3 by 4, which equals 0.75.
Question 5: If x + 7 = 15, what is the value of x?
- 22
- 7
- 8 (Correct answer)
- 6
Correct answer: 8
Subtract 7 from both sides: x = 15 − 7 = 8.
Question 6: A triangle has angles measuring 45° and 65°. What is the measure of the third angle?
- 60°
- 70° (Correct answer)
- 80°
- 90°
Correct answer: 70°
The sum of angles in a triangle is 180°, so the third angle = 180 − 45 − 65 = 70°.
