GED Math Test #6 2 — Questions and Answers
Question 1: Simplify: (4x²)(3x³)
- 12x⁵ (Correct answer)
- 7x⁵
- 12x⁶
- 7x⁶
Correct answer: 12x⁵
Multiply coefficients: 4 × 3 = 12. Add exponents for the same base: x² × x³ = x⁵. Result: 12x⁵.
Question 2: What is the median of: 14, 22, 9, 31, 17, 8, 25?
- 17 (Correct answer)
- 14
- 22
- 18
Correct answer: 17
First sort the data: 8, 9, 14, 17, 22, 25, 31. With 7 values, the median is the 4th value = 17.
Question 3: A triangle has angles measuring 55° and 72°. What is the measure of the third angle?
- 53° (Correct answer)
- 63°
- 48°
- 57°
Correct answer: 53°
The sum of angles in a triangle = 180°. Third angle = 180° − 55° − 72° = 53°.
Question 4: Evaluate: 5² − 3(4 + 2)
- 7 (Correct answer)
- 13
- 1
- 19
Correct answer: 7
Following order of operations (PEMDAS): 5² = 25; (4 + 2) = 6; 3 × 6 = 18; 25 − 18 = 7.
Question 5: Maria earns $14.50 per hour and works 32 hours per week. How much does she earn in a week?
- $464.00 (Correct answer)
- $450.00
- $448.00
- $480.00
Correct answer: $464.00
$14.50 × 32 = $464.00. Multiply the hourly rate by the number of hours worked.
Question 6: A cylindrical can has a radius of 5 cm and a height of 12 cm. What is its volume? (Use π ≈ 3.14)
- 942 cm³ (Correct answer)
- 376.8 cm³
- 1884 cm³
- 471 cm³
Correct answer: 942 cm³
Volume of a cylinder = πr²h = 3.14 × 5² × 12 = 3.14 × 25 × 12 = 942 cm³.
Simplify: (4x²)(3x³)
