TCAP Mathematics 1 — Questions and Answers
Question 1: What is the value of x in the equation 3x + 7 = 22?
- 5 (Correct answer)
- 7
- 3
- 15
Correct answer: 5
Subtract 7 from both sides: 3x = 15. Then divide both sides by 3: x = 5. Verification: 3(5) + 7 = 15 + 7 = 22.
Question 2: What is the area of a triangle with a base of 10 cm and a height of 6 cm?
- 30 sq cm (Correct answer)
- 60 sq cm
- 16 sq cm
- 20 sq cm
Correct answer: 30 sq cm
The area of a triangle is calculated using A = ½ × base × height = ½ × 10 × 6 = 30 square centimeters.
Question 3: Which property states that a + b = b + a?
- Commutative property of addition (Correct answer)
- Associative property of addition
- Distributive property
- Identity property of addition
Correct answer: Commutative property of addition
The commutative property of addition states that changing the order of addends does not change the sum. Similarly, it applies to multiplication.
Question 4: What is the mean (average) of the data set: 4, 8, 12, 16, 20?
- 12 (Correct answer)
- 8
- 16
- 10
Correct answer: 12
The mean is found by adding all values (4 + 8 + 12 + 16 + 20 = 60) and dividing by the count (60 ÷ 5 = 12).
Question 5: What is the slope of the line passing through points (2, 3) and (6, 11)?
- 2 (Correct answer)
- 4
- 1/2
- 8
Correct answer: 2
Slope = (y₂ - y₁)/(x₂ - x₁) = (11 - 3)/(6 - 2) = 8/4 = 2. The line rises 2 units for every 1 unit of horizontal movement.
Question 6: What is the volume of a rectangular prism with length 5 cm, width 3 cm, and height 4 cm?
- 60 cubic cm (Correct answer)
- 12 cubic cm
- 24 cubic cm
- 45 cubic cm
Correct answer: 60 cubic cm
Volume of a rectangular prism = length × width × height = 5 × 3 × 4 = 60 cubic centimeters.
