Answer Key — Math 7 (Grade 7) Midterm — Semester 2, Form A
- B — 60 18 ÷ 0.30 = 60.
- B — 25% Decrease of 20 divided by original 80 is 0.25, or 25%.
- D — $27.00 Tax: 0.08 × 25 = $2.00. Total: $27.00.
- C — $70.80 Tip: 0.18 × 60 = $10.80. Total: $60 + $10.80 = $70.80.
- C — 12 0.15 × 80 = 12.
- B — 56° Complementary angles sum to 90°: 90 - 34 = 56.
- A — 54 square inches Six faces of 3 × 3 = 9 each: 6 × 9 = 54.
- D — 47° Vertical angles are congruent, so it also measures 47°.
- D — 42 square cm A = (1/2)bh = (1/2)(12)(7) = 42.
- D — 10π cm C = 2πr = 2π(5) = 10π cm.
- A — 7 Sum 35 ÷ 5 values = 7.
- C — 60 Experimental probability 18/60 = 0.3; 0.3 × 200 = 60.
- B — 1/2 5 blue out of 10 marbles is 5/10 = 1/2.
- B — Very likely to happen Probabilities close to 1 describe events that are very likely.
- D — 240 20/50 = 40%; 0.40 × 600 = 240.
