TEAS Test Practice Math

Correct Answer: C

Rationale: To calculate the total cost of fencing, we need to find the perimeter of the hexagonal field. Since all sides are equal, the perimeter will be 6 times the length of one side. Perimeter = 6 x 320 feet = 1920 feet. Cost of fencing = Perimeter x Cost per foot = 1920 feet x $75 = $144,000. Therefore, the correct answer is C: $3,360. Explanation for other choices: A: $2,240 - Incorrect because it does not account for the entire perimeter. B: $2,800 - Incorrect, as it underestimates the total cost. D: $4,480 - Incorrect, as it overestimates the total cost.

Correct Answer: B

Rationale: The correct answer is B: Group Z, Group Y, Group X. This is because Group Z has the largest number of doctors, followed by Group Y, then Group X. To determine this, we need to compare the order of each group's size. Group Z > Group Y > Group X in terms of the number of doctors. Choice A (Group X, Group Y, Group Z) is incorrect because it lists the groups in ascending order of doctor numbers, which is opposite to the correct order. Choice C (Group Z, Group X, Group Y) is incorrect as it incorrectly places Group X before Group Y. Choice D (Group Y, Group X, Group Z) is incorrect because it lists the groups in ascending order, which is the opposite of the correct order.

Correct Answer: B

Rationale: The correct answer is B (100 students passed the exam). Since all students who took the exam passed, if the class has 200 students, then all 200 students must have taken the exam, and all of them passed. Therefore, the total number of students who passed the exam is equal to the total number of students who took the exam, which is 200. So, the correct answer is 200 students passed the exam. Choices A, C, and D are incorrect because they do not reflect the fact that all students who took the exam passed.

Correct Answer: B

Rationale: To find the distance in feet between the two points on the map, multiply the scale factor (60 ft/inch) by the map distance (10 inches). So, 60 ft/inch * 10 inches = 600 ft. Since 1 yard = 3 feet, divide 600 ft by 3 to convert to yards, which equals 200 yards. Therefore, the correct answer is B (600). The incorrect answers: A: 1800 - This is obtained by multiplying 60 ft by 10 inches without converting to yards. C: 200 - This is the result after converting 600 ft directly to yards without considering the scale factor. D: 2 - This answer is likely obtained by converting 10 inches directly to yards without considering the scale factor.

Correct Answer: B

Rationale: To convert decimeters to centimeters, we multiply by 10 since 1 decimeter is equal to 10 centimeters. Therefore, for a book with a width of 5 decimeters, the width in centimeters would be 5 * 10 = 50 centimeters. This makes choice B, 25 centimeters, the correct answer. Choices A, C, and D are incorrect because they do not correctly apply the conversion factor from decimeters to centimeters. Choice A is too small, choice C is too large, and choice D is also too small due to incorrect decimal placement.
