  1. What is 15% of 240?

    Answer: 36

    15% of 240 = 0.15 × 240 = 36.

  2. The area of a circle is 49π cm². What is the circumference?

    Answer: 14π cm

    Area = πr² = 49π, so r = 7 cm; circumference = 2πr = 14π cm.

  3. Solve for y: 2y/3 = 8

    Answer: 12

    Multiply both sides by 3/2: y = 8 × (3/2) = 12.

  4. In a group of 50 students, 30 study French and 20 study Spanish. If 10 study both, how many study neither?

    Answer: 10

    Using inclusion-exclusion: French ∪ Spanish = 30 + 20 − 10 = 40; neither = 50 − 40 = 10.

  5. What is the value of √(144/169)?

    Answer: 12/13

    √(144/169) = √144 / √169 = 12/13.

  6. A right triangle has legs of 5 and 12. What is the hypotenuse?

    Answer: 13

    Using the Pythagorean theorem: hypotenuse = √(5² + 12²) = √(25 + 144) = √169 = 13.

  7. If f(x) = 2x² − 3x + 1, what is f(−2)?

    Answer: 15

    f(−2) = 2(−2)² − 3(−2) + 1 = 2(4) + 6 + 1 = 8 + 6 + 1 = 15.
