Correct Answer: B

Rationale: To convert 3 1/2 pints to cups, we know that 1 pint equals 2 cups. Therefore, 3 1/2 pints would be 7 cups (3 pints = 6 cups, 1/2 pint = 1 cup). So, the correct answer is B. Choice A (5 cups) is incorrect because it doesn't account for the additional 1/2 pint. Choice C (6 cups) is incorrect as it only considers 3 pints. Choice D (4 cups) is incorrect because it doesn't account for the additional 1/2 pint.

Correct Answer: A

Rationale: To find the cost of 6 books, we can use the proportion method. Since 3 books cost $4, 1 book costs $4/3. To find the cost of 6 books, we multiply the cost of 1 book by 6, which gives $8. Therefore, the correct answer is A: $8. The other choices are incorrect because they do not follow the logical calculation based on the initial cost of 3 books and the concept of proportionality.

Correct Answer: A

Rationale: To find the number of boys born last night, we first calculate the number of girls born, which is 45% of 76 (0.45 * 76 = 34.2). Since we can't have a fraction of a baby, we round this to the nearest whole number, which is 34. Therefore, the remaining babies (76 - 34) are boys, giving us a total of 42 boys born last night. Choice A (42) is correct. Choices B, C, and D are incorrect as they do not correctly calculate the number of boys born based on the information provided.

Correct Answer: B

Rationale: To find the result of multiplying 10 by 5, we simply perform the operation 10 x 5, which equals 50. This is because multiplication is a repeated addition, so 10 multiplied by 5 is the same as adding 10 together 5 times. Therefore, the correct answer is B. Choice A (65) is incorrect as it is the result of adding 10 and 5, not multiplying. Choice C (45) and D (55) are incorrect as they are not the result of multiplying 10 by 5.

Correct Answer: C

Rationale: To solve this problem, we first find the total number of players on the team by setting up a proportion: 4 players represent 5%, so 1% is equal to 0.8 players. Thus, the total number of players is 4 divided by 0.05, which equals 80 players. Since 4 players have long hair, there are 80 - 4 = 76 players with short hair. The correct answer is C. Option A, B, and D are incorrect because they do not align with the calculated total number of players on the team.
