CAHSEE Math 2 — Questions and Answers
Question 1: A store sells notebooks for $2.75 each. If Maria buys 4 notebooks and pays with a $20 bill, how much change does she receive?
- $8.00
- $9.00 (Correct answer)
- $11.00
- $12.25
Correct answer: $9.00
4 × $2.75 = $11.00, and $20.00 − $11.00 = $9.00 change.
Question 2: What is the slope of the line that passes through the points (2, 5) and (6, 13)?
- 1
- 2 (Correct answer)
- 3
- 4
Correct answer: 2
Slope = (13 − 5) / (6 − 2) = 8 / 4 = 2.
Question 3: Which of the following is equivalent to 3(x + 4) − 2x?
- x + 4
- x + 12 (Correct answer)
- 5x + 12
- x + 7
Correct answer: x + 12
3(x + 4) − 2x = 3x + 12 − 2x = x + 12.
Question 4: A triangle has angles measuring 45° and 75°. What is the measure of the third angle?
- 50°
- 55°
- 60° (Correct answer)
- 65°
Correct answer: 60°
The angles of a triangle sum to 180°, so 180° − 45° − 75° = 60°.
Question 5: Simplify: (4x²)(3x³)
- 7x⁵
- 12x⁵ (Correct answer)
- 12x⁶
- 7x⁶
Correct answer: 12x⁵
Multiply coefficients (4 × 3 = 12) and add exponents (2 + 3 = 5) to get 12x⁵.
Question 6: A bag contains 3 red, 5 blue, and 2 green marbles. If one marble is drawn at random, what is the probability it is blue?
- 1/2 (Correct answer)
- 1/5
- 3/10
- 5/10
Correct answer: 1/2
There are 5 blue out of 10 total marbles: 5/10 = 1/2.
Question 7: What is 15% of 240?
- 30
- 36 (Correct answer)
- 40
- 42
Correct answer: 36
15% × 240 = 0.15 × 240 = 36.
