TEAS Practice Math Test

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: B

Rationale: To calculate the new dosage after a 30% decrease, we multiply the current dosage (340 mg) by (100% - 30%) = 70%. 340 mg * 70% = 340 mg * 0.70 = 238 mg. Therefore, the correct answer is B. Choice A (70 mg): This is incorrect because it represents a 30% decrease from 100 mg, not the initial dosage of 340 mg. Choice C (270 mg): This is incorrect because it does not account for the 30% decrease from the initial dosage of 340 mg. Choice D (340 mg): This is incorrect because the question asks for the dosage after a 30% decrease, not the current dosage.

Correct Answer: A

Rationale: The correct answer is A (35). To find the number of students who chose blue, multiply the total number of students by the percentage that chose blue: 100 x 0.35 = 35. This calculation gives us the number of students who said blue is their favorite color. The other choices are incorrect because they do not correctly calculate the number of students who chose blue based on the given percentage. Choice B (25), C (20), and D (10) do not accurately represent 35% of the total number of students. Therefore, choice A is the correct answer based on the calculation method provided.
