Correct Answer: C

Rationale: To find the width, we first calculate the total length of the rectangle by multiplying the length by 2 (since there are 2 lengths in a rectangle). 12 cm x 2 = 24 cm. Subtracting this from the total perimeter of 36 cm gives us 36 cm - 24 cm = 12 cm. Since the width is divided into 2 sides, we divide 12 cm by 2 to get the width of 6 cm. Therefore, the correct answer is C: 6 cm. Choice A (3 cm) is incorrect because it does not account for the total perimeter. Choice B (12 cm) is incorrect as it represents the length, not the width. Choice D (8 cm) is incorrect as it does not align with the calculations based on the given information.

Correct Answer: B

Rationale: The correct answer is B (1.07548) because it has the largest value among the given numbers. To determine this, we compare the numbers using their place values. The number with the largest value is the one with the highest digit in the leftmost place. In this case, 1.07548 has the largest value as it has 1 in the ones place, which is greater than 1 in the tenths place in A and C, and the highest value in the thousandths place compared to D. Choices A, C, and D have smaller values because their leftmost digit is smaller than the corresponding digit in B.

Correct Answer: A

Rationale: To solve this question, we first need to find the ratio of girls to boys, which is 3:2. Then, we can set up a proportion to determine the number of girls. Since there are 3 girls for every 2 boys, the total ratio is 3+2=5 parts. To find the number of girls, we divide the total number of students by the total parts (650/5=130). Finally, we multiply the number of parts allocated to girls by the ratio of girls in the total parts (130*3=390). Therefore, there are 390 girls in Jim's school. Choice A (260) is incorrect as it does not consider the correct ratio. Choice B (130) is incorrect as it calculates the total parts instead of the number of girls directly. Choice C (65) is incorrect as it only considers one part of the ratio. Choice D (390) is incorrect as it miscalculates the number of boys, not

Correct Answer: C

Rationale: Step 1: Identify the integer closest to 4.6, which is 5. Step 2: Determine the distance between 4.6 and both neighboring integers: 4 (0.6 away) and 5 (0.4 away). Step 3: Since 4.6 is closer to 5, rounding to the nearest integer gives us 5, making choice C the correct answer. Summary: Choice A is incorrect as it is the integer below 4.6. Choice B is incorrect as it is not the closest integer to 4.6. Choice D is incorrect as it is greater than 4.6.

Correct Answer: A

Rationale: To solve the equation 2x + 8 = 0, we first isolate x by subtracting 8 from both sides. This gives us 2x = -8. Then, divide by 2 on both sides to get x = -4 (Choice A). This is the correct answer because -4 satisfies the equation. Choices B, C, and D are incorrect as they do not yield a solution that makes the equation true when substituted back into it.
