CAASPP Mathematics 4 — Questions and Answers
Question 1: What is the slope of a line that passes through the points (2, 3) and (6, 11)?
- 1
- 2 (Correct answer)
- 4
- 8
Correct answer: 2
Slope = (11 − 3) ÷ (6 − 2) = 8 ÷ 4 = 2.
Question 2: Which fraction is equivalent to 0.6̄ (0.666...)?
- 3/5
- 2/3 (Correct answer)
- 6/9
- 5/8
Correct answer: 2/3
0.666... = 2/3; note that 6/9 simplifies to 2/3 as well, but 2/3 is the simplest form.
Question 3: A recipe calls for 2½ cups of flour to make 24 cookies. How many cups of flour are needed to make 60 cookies?
- 5 cups
- 6 cups
- 6¼ cups (Correct answer)
- 6½ cups
Correct answer: 6¼ cups
Ratio: 2.5 ÷ 24 = x ÷ 60, so x = 2.5 × 60 ÷ 24 = 150 ÷ 24 = 6.25 = 6¼ cups.
Question 4: Simplify: √144
- 11
- 12 (Correct answer)
- 13
- 14
Correct answer: 12
12 × 12 = 144, so √144 = 12.
Question 5: The mean of five test scores is 82. If four of the scores are 75, 85, 90, and 78, what is the fifth score?
- 80
- 82 (Correct answer)
- 84
- 86
Correct answer: 82
Total = 82 × 5 = 410; sum of four scores = 328; fifth score = 410 − 328 = 82.
Question 6: A square garden has a perimeter of 52 feet. What is the area of the garden?
- 104 ft²
- 144 ft²
- 169 ft² (Correct answer)
- 196 ft²
Correct answer: 169 ft²
Side = 52 ÷ 4 = 13 feet; area = 13² = 169 ft².
Question 7: Which inequality represents 'x is at most 7'?
- x > 7
- x < 7
- x ≥ 7
- x ≤ 7 (Correct answer)
Correct answer: x ≤ 7
'At most 7' means x cannot exceed 7, so x ≤ 7.
