Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A: Mile is bigger; 1 mile is 1.609 km. This is because a mile is a longer unit of measurement compared to a kilometer. The conversion factor is 1 mile equals 1.609 kilometers. To convert miles to kilometers, you multiply the number of miles by 1.609. The other choices are incorrect because: B: Kilometer is bigger; 1 km is 1.609 miles - This is incorrect as a kilometer is shorter than a mile. C: Mile is bigger; 1 mile is 1.5 km - This is incorrect as 1 mile is actually equal to about 1.609 kilometers. D: Kilometer is bigger; 1 km is 2 miles - This is incorrect as a kilometer is shorter than 2 miles.

Correct Answer: A

Rationale: The correct answer is A: Equals. In math, "is" signifies equality between two expressions or values. It indicates that the quantities on both sides of the "=" sign are the same. For example, in the equation 2 + 3 = 5, the "is" represents that the sum of 2 and 3 equals 5. Explanation for other choices: B: Multiply - The symbol for multiplication is "*", not "is." C: Subtract - The symbol for subtraction is "-", not "is." D: Add - The symbol for addition is "+", not "is." Therefore, the correct interpretation of "is" in math is to denote equality, making choice A the correct answer.

Correct Answer: A

Rationale: The correct answer is A: y = 3x. To find the relationship between x and y, we can observe that y is always 3 times the value of x in each row. For example, when x = 2, y = 6 (6 = 3 * 2). This pattern holds true for all data points provided. Therefore, the correct equation is y = 3x. Choice B (x = 3y) is incorrect because it suggests that x is 3 times the value of y, which is not the case based on the given data. Choice C (y = x/3) is incorrect as it implies that y is one-third of x, which does not match the relationship shown in the table. Choice D (y = x + 3) is incorrect as it simply adds 3 to x to get y, which is not consistent with the provided data points.

Correct Answer: B

Rationale: To calculate a 30% decrease, you multiply the current dosage (340 mg) by 0.30 to find the decrease amount: 340 mg x 0.30 = 102 mg. Subtract the decrease from the current dosage to get the new dosage: 340 mg - 102 mg = 238 mg (Option B). Option A (70 mg) is incorrect as it represents a 79% decrease. Option C (270 mg) is incorrect as it does not account for the 30% decrease. Option D (340 mg) is incorrect as it does not reflect the required decrease.

Correct Answer: A

Rationale: The correct answer is A: 1328.35. To calculate the total cost, we first add up the costs of airfare, hotel (5 nights), sightseeing, and meals. Next, we calculate the cost of additional hotel nights after the 10% discount. Finally, we sum up all the costs to get the total amount Margery will spend. The other choices are incorrect because they do not follow the correct calculation process or include the discount on additional hotel nights.
