Question 1 of 5
Multiply: 35 25 =
Correct Answer: D
Rationale: To multiply 35 25, break it down into (30 + 5) 25. Now distribute: (30 25) + (5 25) = 750 + 125 = 875. Therefore, 35 25 = 875. Choices A, B, and C are incorrect because they do not represent the correct result of multiplying 35 by 25. Choice A is 1000 times smaller than the correct answer, Choice B is 100 times smaller, and Choice C is 10 times smaller, making them all incorrect. The correct answer is Choice D, 8.75.
Question 2 of 5
You need to repaint a cylindrical water tank with a diameter of 2 meters and a height of 3 meters. Assuming one can of paint covers 10 sq m, how many cans do you need to cover only the exterior surface?
Correct Answer: C
Rationale: To find the surface area of the cylinder, calculate the lateral surface area using the formula 2?rh, where r is the radius (half of the diameter) and h is the height. Substituting the values, we get 2 * ? * 1 * 3 = 6? square meters. Since each can covers 10 sq m, divide the total surface area by the coverage area per can: 6? / 10 ≈ 1.9 cans. Since you can't buy a fraction of a can, you would need to round up, so you would need 2 cans to cover the entire exterior surface. Therefore, you would need 2 * 6 = 12 cans in total. Choices A, B, and D are incorrect as they do not consider the correct surface area calculation or the rounding up to the nearest whole number of cans required.
Question 3 of 5
In a scale drawing for a toy rocket, 1 inch = 6 inches. If the rocket is 6 inches tall on the drawing, how tall will it be in reality?
Correct Answer: B
Rationale: In the scale drawing, 1 inch represents 6 inches in reality. If the rocket is 6 inches tall on the drawing, the actual height of the rocket would be 6 inches x 6 = 36 inches, which is equal to 3 feet or 1 yard. Therefore, the correct answer is 6 feet. Choice A is incorrect because the actual height is more than 1 foot. Choice C is incorrect as 36 inches is equivalent to 1 yard. Choice D is incorrect because 36 inches is not equal to 2 yards.
Question 4 of 5
A landscaping plan is drawn on a 1:50 scale. If a deck in the plan measures 12 cm by 10 cm, how large is the deck in real life?
Correct Answer: B
Rationale: Since the landscaping plan is drawn on a 1:50 scale, the real-life dimensions of the deck can be calculated by multiplying the dimensions on the plan by the scale factor. The dimensions given are 12 cm by 10 cm. Multiplying these dimensions by the scale factor of 50 gives us 600 cm by 500 cm, which is equivalent to 6 m by 5 m in real life. Choice A is incorrect as it doesn't consider the scale factor. Choice C and Choice D are incorrect as they are not the result of multiplying the dimensions by the scale factor.
Question 5 of 5
Tamison bought 20 stamps for 29� each and 40 stamps for 42� each. If she gave the postal worker $25, how much change did she receive?
Correct Answer: A
Rationale: First, calculate the total cost of the 20 stamps bought at 29� each: 20 stamps * 29� = $5.80. Next, calculate the total cost of the 40 stamps bought at 42� each: 40 stamps * 42� = $16.80. The total cost of all stamps is $5.80 + $16.80 = $22.60. If Tamison gave $25 to the postal worker, her change is $25 - $22.60 = $2.40. Therefore, the correct answer is A. Option B, C, and D are incorrect as they do not reflect the correct change Tamison received after buying the stamps.
