- A6 m
- B7 m
- C8 m
- D10 m
Show answer & explanation
Correct answer: B
For a right triangle, tan(θ) = opposite/adjacent. tan 30° = height/12 m. tan 30° = √3/3 ≈ 0.577. Height = 12 * 0.577 ≈ 6.93 m, which rounds to 7 m. The closest answer is 7 m (option B). 💡 Strategy tip: Use the tangent function: tan θ = opposite/adjacent.
- AAs advertising dollars increase, the number of loaves sold tends to increase.
- BAs advertising dollars increase, the number of loaves sold tends to decrease.
- CThere is no clear association between advertising dollars and loaves sold.
- DThe association is curvilinear.
Show answer & explanation
Correct answer: A
All the data points show larger advertising amounts paired with larger loaf sales, indicating a positive (direct) association. 💡 Strategy tip: Look for a consistent increase or decrease in the paired values.
- A2^5
- B5^2
- C2^4
- D10^5
Show answer & explanation
Correct answer: A
From the table, when n = 5 the value is 32, and 2^5 = 32. The other choices give different numbers. 💡 Strategy tip: Match the exponent to the base shown in the table.
- AAccount A
- BAccount B
- CAccount C
- DAll earn the same amount
Show answer & explanation
Correct answer: B
Interest for each account: A = 500×0.03 = $15; B = 450×0.04 = $18; C = 600×0.025 = $15. Account B earns the most. 💡 Strategy tip: Multiply principal by rate to find simple interest for one year.
- A5
- B3
- C4
- D7
Show answer & explanation
Correct answer: A
Add 7 to both sides: \(5x = 25\). Divide by 5: \(x = 5\). 💡 Strategy tip: Undo operations in the reverse order they were applied to the variable.

Show answer & explanation
Correct answer: A
The slope is the change in miles divided by the change in days. From Day 1 to Day 2, the miles increase from 12 to 20, a change of 8 miles for 1 day. Thus the slope is 8 miles per day. 💡 Strategy tip: Use two points from the table and apply slope = (y₂‑y₁)/(x₂‑x₁).
- A\sqrt{4^{2}+10^{2}}
- B4+10
- C4^{2}+10^{2}
- D4\times10
Show answer & explanation
Correct answer: A
The ladder, wall, and ground form a right triangle. By the Pythagorean theorem, length = \sqrt{(4)^2+(10)^2}. 💡 Strategy tip: Identify the right‑triangle and write \(c=\sqrt{a^2+b^2}\).
- A\sqrt{2}
- B\frac{5}{8}
- C3.75
- D-2
Show answer & explanation
Correct answer: A
\sqrt{2} cannot be expressed as a fraction of two integers and its decimal expansion goes on forever without repeating, so it is irrational. 💡 Strategy tip: An irrational number cannot be written as a ratio of two integers.
- A5 kg
- B8 kg
- C10 kg
- D12 kg
Show answer & explanation
Correct answer: C
Let a = kg of Type A, b = kg of Type B. a + b = 20 and 2a + 3.5b = 55. Solve: from first, b = 20‑a. Substitute: 2a + 3.5(20‑a) = 55 → 2a + 70 – 3.5a = 55 → -1.5a = -15 → a = 10. Therefore 10 kg of Type A flour (option C). 💡 Strategy tip: Set up two equations: one for total weight, one for total cost, then solve the system.
- A(1,4)
- B(7,4)
- C(1,-6)
- D(7,-6)
Show answer & explanation
Correct answer: A
Apply the translation: x‑coordinate minus 3, y‑coordinate plus 5. (4‑3, ‑1+5) = (1,4). The other points do not match the rule. 💡 Strategy tip: A translation (a,b) changes (x,y) to (x+a, y+b).
