TEAS 7 Math Practice Test

Correct Answer: A

Rationale: To simplify the expression, you first add the numbers together: 1.034 + 0.275 = 1.309. Then, subtract 1.294 from the result: 1.309 - 1.294 = 0.015. Therefore, the correct answer is A (0.015). Choices B, C, and D are incorrect as they do not match the calculated result of 0.015.

Correct Answer: A

Rationale: To find the number of respondents who use smartphones for email, we multiply the percentage (60%) by the total number of respondents (5,000). 60% of 5,000 = 0.60 * 5,000 = 3,000 respondents. Therefore, choice A (3,000 respondents) is the correct answer. Choices B, C, and D are incorrect because they do not reflect the correct calculation based on the given percentage and total number of respondents.

Correct Answer: A

Rationale: To find the combinations Tom can purchase, you need to determine the total cost of ink cartridges and paper. Let c be the number of cartridges and p be the number of reams. The total cost is 30c + 5p. Since Tom has $100, the inequality is 30c + 5p ≤ 100. This is because the total cost should not exceed $100. Therefore, choice A is correct. Choice B is incorrect because it implies Tom can only spend exactly $100, which restricts his options. Choice C is incorrect as it states the total cost must be more than $100, which goes against the budget constraint. Choice D is incorrect as it allows for the total cost to be less than $100, which is not a valid option given Tom's budget.

Correct Answer: D

Rationale: The correct answer is D: 0.16%. To find the percentage equivalent of a decimal, we multiply the decimal by 100. So, 0.0016 x 100 = 0.16%. Choice A (16%) is incorrect because it represents the decimal as a whole number, not a percentage. Choice B (160%) is incorrect as it incorrectly multiplies the decimal by 1000 instead of 100. Choice C (1.60%) is incorrect as it incorrectly places the decimal point in the wrong position, resulting in an incorrect percentage value.

Correct Answer: C

Rationale: To determine the correct dosage, multiply the patient's weight (60 kg) by the prescribed dosage (5 mg/kg): 60 kg x 5 mg/kg = 300 mg. Choice C is correct. Choices A, B, and D are incorrect as they do not result from the correct calculation. Choice A (100 mg) is too low, Choice B (150 mg) is also too low, and Choice D (400 mg) is too high based on the calculation.
