Correct Answer: C

Rationale: To find the perimeter of a rectangle, we add up all four sides. Given length = 12 cm, width = 5 cm. Perimeter = 2(length) + 2(width) = 2(12) + 2(5) = 24 + 10 = 34 cm. Therefore, the correct answer is C (34 cm). Choice A (17 cm) is incorrect, as it only considers the length and width separately. Choice B (24 cm) is incorrect, as it only adds the length and width once each. Choice D (40 cm) is incorrect, as it incorrectly doubles both the length and width.

Correct Answer: C

Rationale: To calculate Annie's total bill: 1. Cost of shirts: 5 shirts x $3 = $15 2. Cost of pants: 4 pants x $6 = $24 3. Cost of mending: 2 items x $5 = $10 4. Subtotal = $15 + $24 + $10 = $49 5. Add 8% sales tax: $49 x 0.08 = $3.92 6. Total bill = $49 + $3.92 = $52.92 Therefore, the correct answer is C ($52.92). The other choices are incorrect because they do not accurately factor in the cost of mending and sales tax. Option A, B, and D do not consider the additional charges for mending and tax, leading to incorrect totals.

Correct Answer: B

Rationale: The correct answer is B: c = p/m. To calculate the cost of gas per mile, we need to divide the price of gas (p) by the car's average mileage (m) in miles per gallon. This gives us the cost of gas per mile. Rationale: 1. The formula for cost per mile is calculated by dividing the price of gas by the car's average mileage. 2. Choice A (c = dp/m) is incorrect because it multiplies the price of gas by distance before dividing by mileage, which is not the correct calculation for cost per mile. 3. Choice C (c = mp/d) is incorrect as it multiplies average mileage by price before dividing by distance, which is not the correct calculation for cost per mile. 4. Choice D (c = m/p) is incorrect as it divides mileage by price, which does not give the cost of gas per mile.

Correct Answer: D

Rationale: To determine the order from least to greatest, we need to evaluate each expression. First, calculate each expression: 2^-1 = 1/2 -(4/3) = -4/3 (-1)^3 = -1 (2/5) = 2/5 Now, compare the values: -4/3 is the smallest, followed by -1, then 2/5, and finally 1/2. Therefore, the correct order is -(4/3), (-1)^3, (2/5), 2^-1. Option D correctly lists the expressions in this order. Option A is incorrect because it has the wrong order of the expressions. Option B is incorrect as it has a different order compared to the correct one. Option C is incorrect as it also has a different order than the correct one.
