  1. Which of the following is the prime factorization of 60?

    Answer: 2² × 3 × 5

    60 = 4 × 15 = 2² × 3 × 5, which are all prime factors.

  2. A triangle has angles measuring 45° and 75°. What is the measure of the third angle?

    Answer: 60°

    The sum of angles in a triangle is 180°, so 180 − 45 − 75 = 60°.

  3. If y = 2x − 3 and x = 5, what is the value of y?

    Answer: 7

    Substitute x = 5: y = 2(5) − 3 = 10 − 3 = 7.

  4. A car travels 240 miles in 4 hours. What is its average speed in miles per hour?

    Answer: 60 mph

    Speed = distance ÷ time = 240 ÷ 4 = 60 mph.

  5. What is 15% of 80?

    Answer: 12

    15% of 80 = 0.15 × 80 = 12.

  6. Which of the following sets of numbers is ordered from least to greatest?

    Answer: −5, −2, 0, 3

    On a number line, −5 < −2 < 0 < 3, so −5, −2, 0, 3 is correct.

  7. A cylinder has a radius of 3 inches and a height of 10 inches. Using π ≈ 3.14, what is the approximate volume?

    Answer: 282.6 in³

    V = πr²h = 3.14 × 9 × 10 = 282.6 in³.
