TEAS Practice Math Test

Correct Answer: C

Rationale: The mean time for the women who ran the 200m event at the 2008 Olympic Games can be calculated by summing all the times and dividing by the total number of times. Sum of times = 22.33 + 22.50 + 22.50 + 22.61 + 22.71 + 22.72 + 22.83 + 23.22 = 182.42 Total number of times = 8 Mean time = 182.42 / 8 = 22.8025 ≈ 22.68 sec (Choice C) Therefore, the correct answer is C (22.68 sec) as it is the closest to the calculated mean time. Incorrect choices: A: 22.50 sec - This is not the mean of the given times. B: 22.66 sec - Not the mean. D: 22.77 sec - Not the mean.

Correct Answer: B

Rationale: To find the average weight of each item, we first subtract Jerry's weight from the elevator's weight limit: 800 - 200 = 600 pounds. Then, we divide this by the number of items (4): 600 / 4 = 150 pounds. This means each item should weigh 150 pounds on average to not exceed the weight limit. Choice B (150 pounds) is correct. Choice A (128 pounds) is too light, which would allow the elevator's weight limit to be exceeded. Choice C (175 pounds) and choice D (180 pounds) are too heavy, which would also exceed the weight limit.

Correct Answer: C

Rationale: To convert meters to centimeters, we know that 1 meter is equal to 100 centimeters. So, to find how many centimeters are in 7 meters, we multiply 7 by 100, which equals 700 centimeters. Therefore, the correct answer is C. Choice A is incorrect because it doesn't account for the conversion factor between meters and centimeters. Choice B is incorrect as it only considers 1 meter as 10 centimeters instead of 100. Choice D is incorrect as it overestimates the conversion, as 7 meters is not equal to 7000 centimeters.

Correct Answer: A

Rationale: To calculate Jonathan's monthly bill for x roaming minutes, we need to add the flat rate of $65 to the charge per minute of $0.12 multiplied by the number of roaming minutes x. Therefore, the correct expression is 65 + 0.12x. Choice A (65 + 0.12x) is correct because it accurately represents the total bill by adding the flat rate and the variable charge for roaming minutes. Choices B (65x + 0.12), C (65.12x), and D (65 + 0.12x) are incorrect because they do not correctly combine the flat rate and the charge per minute for roaming. Choice B incorrectly multiplies the flat rate by the variable x, Choice C combines the flat rate and the charge incorrectly, and Choice D does not account for the flat rate in the correct way.

Correct Answer: D

Rationale: The correct answer is D: $144.65. To find the total cost of Susan's outfit, you need to add up the costs of the dress, shoes, and accessories. $69.99 (dress) + $39.99 (shoes) + $34.67 (accessories) = $144.65. This is the total cost of Susan's outfit. Explanation for incorrect choices: A: $69.99 - This is only the cost of the dress and does not include the shoes and accessories. B: $75.31 - This amount is not the total cost as it only includes the dress and shoes, excluding the accessories. C: $109.98 - This sum is the total of the dress and shoes but does not include the accessories. Therefore, the correct answer is D as it includes the combined cost of all items purchased.
