Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct answer is A: 9.0 inches. To calculate the total rainfall for May, June, and July, we add up the rainfall values for these months on the graph. May has 3 inches, June has 2.5 inches, and July has 3.5 inches. Adding these values together gives us 3 + 2.5 + 3.5 = 9.0 inches. Therefore, the correct total rainfall for these months is 9.0 inches. Choice B (8.4 inches) is incorrect because it does not match the sum of the rainfall values for May, June, and July. Choice C (7.5 inches) is also incorrect as it is lower than the actual total. Choice D (10.5 inches) is incorrect as it is higher than the actual total calculated from the graph.

Correct Answer: A

Rationale: Correct Answer: A Rationale: To convert Fahrenheit to Celsius, you first subtract 32 from the Fahrenheit temperature and then divide by 1.8. This is because the conversion formula is (F - 32) / 1.8. To convert Celsius to Fahrenheit, you multiply the Celsius temperature by 1.8 and then add 32. The formula for this conversion is (C * 1.8) + 32. Therefore, choice A is correct as it follows the correct conversion formulas for both Fahrenheit to Celsius and Celsius to Fahrenheit. Summary of other choices: B: Incorrect because dividing by 2 in Fahrenheit to Celsius conversion is incorrect. C: Incorrect because multiplying by 2 in Fahrenheit to Celsius conversion is incorrect. D: Incorrect because subtracting 30 in Fahrenheit to Celsius conversion is incorrect.

Correct Answer: B

Rationale: The correct answer is B: Find all pairs of numbers that multiply to give the number. To find factors, we need to identify pairs of numbers that, when multiplied together, result in the original number. This method ensures that we consider all possible combinations of factors. Dividing the number by all possible numbers (A) is not efficient and may lead to overlooking certain factors. Listing all the multiples of the number (C) is incorrect as it focuses on multiples rather than factors. Adding the digits of the number together (D) is unrelated to finding factors.

Correct Answer: A

Rationale: The correct answer is A because a factor is a number that can be multiplied by another number to give the original number. For example, in the case of 6, factors would be 1, 2, 3, and 6. These numbers can be multiplied to get 6. Choice B is incorrect because it describes a divisor. Choice C is incorrect as it does not specifically define a factor but rather a relationship between two numbers. Choice D is incorrect as factors can be numbers less than, equal to, or greater than 1.

Correct Answer: D

Rationale: To find the cost of 1 syringe, divide $660 by 55 (55 syringes in a box) = $12 per syringe. To find the cost of 4 syringes, multiply $12 by 4 = $48. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not correctly calculate the cost based on the given information.
