Correct Answer: C

Rationale: To find the perimeter of the honeycomb cell, we add the lengths of all six sides, which are 8mm each. Perimeter = 6 * 8mm = 48mm. Choice C (48mm) is correct. Other choices are incorrect because they do not account for the total length of all sides. Option A (32mm) would be the perimeter of a square with sides of 8mm. Option B (40mm) and Option D (56mm) are not the correct total length of all six sides.

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.

Correct Answer: C

Rationale: To add 7 2/3 and 5 5/12, first convert both mixed numbers to improper fractions: 7 2/3 = 23/3 and 5 5/12 = 65/12. Then, add the fractions: 23/3 + 65/12 = 92/12 + 65/12 = 157/12. Finally, convert 157/12 back to a mixed number: 157 ÷ 12 = 13 with a remainder of 1, resulting in 13 1/12. Therefore, the correct answer is C (13 1/12). Choices A, B, and D are incorrect as they do not match the calculated sum of the two mixed numbers.

Correct Answer: A

Rationale: The correct answer is A: 0.09%. To convert 0.0009 to a percentage, you move the decimal point two places to the right. This results in 0.09%, which is equal to 0.0009. Choice B: 9% is incorrect because it represents a value that is 100 times greater than 0.0009. Choice C: 0.01% is incorrect because it represents a value that is 10 times smaller than 0.0009. Choice D: 0.90% is incorrect because it is 10 times greater than 0.0009.

Correct Answer: C

Rationale: To find three tenths of 90, we multiply 90 by 3/10. 90 * 3/10 = 270/10 = 27. Therefore, the correct answer is C: 27. Choice A (18) is incorrect as it is 2 tenths of 90. Choice B (45) is incorrect as it is half of 90. Choice D (36) is also incorrect as it is 4 tenths of 90.
