TEAS Practice Test Math

Correct Answer: B

Rationale: To calculate the total cost (T), we sum up the initial charge with the additional charges for circular and rectangular tablecloths. The correct expression is B: 5c + 3.5r + 40 = T. This is because we add the charges for circular and rectangular tablecloths to the initial charge of $40 to get the total cost. Choice A subtracts the initial charge instead of adding it. Choice C subtracts the initial charge and swaps the coefficients for circular and rectangular tablecloths. Choice D incorrectly adds the initial charge after the coefficients for circular and rectangular tablecloths.

Correct Answer: A

Rationale: The correct answer is A because an integer is defined as a whole number that can be positive, negative, or zero. Integers do not include fractions or decimals (eliminating choices B and C) or percentages (eliminating choice D). Integers are the set of numbers {..., -3, -2, -1, 0, 1, 2, 3, ...} and do not include numbers with decimal points or fractions. Therefore, choice A is the only option that accurately describes what defines an integer.

Correct Answer: B

Rationale: To find the number of students in the respiratory care program, we need to calculate the percentage of students in that program based on the pie chart. The respiratory care program occupies 19% of the pie chart. 19% of 800 students is 0.19 * 800 = 152. Therefore, the correct answer is B: 152. Choice A (336) is incorrect as it represents the percentage of students in a different program, not respiratory care. Choice C (144) and Choice D (168) are also incorrect as they do not correspond to the percentage allocated for the respiratory care program in the pie chart.

Correct Answer: A

Rationale: To simplify 3.45 * 0.53, multiply the numbers together: 3.45 * 0.53 = 1.8285 (Answer A). This is correct because when multiplying decimals, you multiply as if they were whole numbers and then place the decimal point in the answer based on the total number of decimal places in the factors. Summary of other choices: B: 18.285 - Incorrect as it is the result of adding the two numbers. C: 0.18285 - Incorrect as it is the result of placing the decimal point incorrectly. D: 182.85 - Incorrect as it is the result of ignoring the decimal places in the factors.

Correct Answer: B

Rationale: To find the average time per mile, we calculate the total time taken for both segments (25 minutes for 5 miles + 15 minutes for 3 miles = 40 minutes for 8 miles). Then, we divide the total time by the total distance (40 minutes ÷ 8 miles = 5 minutes per mile). Therefore, the correct answer is B. Choice A (7 minutes) is incorrect because it does not align with the calculated average time per mile of 5 minutes. Choice C (6.5 minutes) is incorrect as it is not the accurate average based on the given data. Choice D (8.5 minutes) is incorrect as it also does not match the calculated average time per mile of 5 minutes.
