TEAS 7 Math Practice Test

Correct Answer: B

Rationale: The correct answer is B: 1 centimeter. The average length of a human eyelash is around 1 centimeter. This length is suitable for protecting the eyes from debris and dust particles while allowing them to function properly. Choice A, 1 nanometer, is far too small for an eyelash. Choice C, 1 meter, and choice D, 1 kilometer, are both significantly longer than the actual length of a human eyelash, making them unrealistic and incorrect options.

Correct Answer: C

Rationale: To find the cost of one box of crackers, we set up a system of equations. Let x be the cost of one container of yogurt and y be the cost of one box of crackers. From the given information, we have: 4x + 3y = 9.55 2x + 2y = 5.90 Solving the system of equations, we find x = 1.45 and y = 2.25. Therefore, one box of crackers costs $2.25, making choice C the correct answer. Incorrect choices: A: $1.75 - Incorrect because it doesn't match the calculated cost. B: $2.00 - Incorrect, as it does not align with the calculated cost. D: $2.50 - Wrong, as it does not correspond to the calculated value.

Correct Answer: B

Rationale: The correct answer is B because it accurately describes the rate of change as the snow melting by 5 centimeters every day. This statement represents a consistent decrease in the snow level over time. Choice A is incorrect as it implies a higher rate of melting than what is described. Choice C is incorrect as it describes an increase rather than a decrease. Choice D is also incorrect as it describes an increase instead of the intended decrease in snow level. Therefore, choice B is the most accurate representation of the rate of change in this scenario.

Correct Answer: B

Rationale: To find the approximate number of people who voted for the proposition, we multiply the town's population by the percentage that voted: 51,623 * 9.5% = 51,623 * 0.095 = 4,904. Therefore, approximately 5,000 people voted for the proposition. Choice A (3,000) is too low because 9.5% of the population would result in more voters. Choice C (7,000) is too high because it exceeds the calculation based on the given percentage. Choice D (10,000) is also too high as it overestimates the number of voters based on the percentage provided.

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.
