GED Math Test #9 2

Question 1

What is the value of 4³ − √64?

Accepted Answer

56

Answer

4³ = 4 × 4 × 4 = 64. √64 = 8. 64 − 8 = 56.

Question 2

Line m is parallel to line n. A transversal crosses both lines forming angles. If one angle is 65°, what is its alternate interior angle?

Accepted Answer

65°

Answer

Alternate interior angles formed by a transversal cutting parallel lines are equal. Therefore the alternate interior angle is also 65°.

Question 3

A spinner has 8 equal sections numbered 1–8. What is the probability of landing on a number greater than 5?

Accepted Answer

3/8

Answer

Numbers greater than 5 are: 6, 7, 8 — that is 3 numbers. P = 3/8.

Question 4

Combine like terms: 4a² − 3b + 2a² + 7b

Accepted Answer

6a² + 4b

Answer

Group like terms: (4a² + 2a²) + (−3b + 7b) = 6a² + 4b. Only terms with the same variable and exponent can be combined.

Question 5

A store sells apples at $1.20 each and oranges at $0.90 each. Jake buys 5 apples and 4 oranges. How much does he spend?

Accepted Answer

$9.60

Answer

Apples: 5 × $1.20 = $6.00. Oranges: 4 × $0.90 = $3.60. Total = $6.00 + $3.60 = $9.60.
