Practice Math TEAS TEST

Correct Answer: A

Rationale: Step-by-step rationale: 1. Friend 1 eats half, leaving half for the other 3 friends. 2. The remaining half is divided equally among the 3 friends. 3. So, each friend gets 1/3 of the remaining half. 4. 1/3 represents the portion each of the other 3 friends receives, making choice A the correct answer. Summary: - Incorrect choices B, C, and D are not correct as they do not accurately represent the portion each of the other three friends would receive after one friend eats half of the pizza.

Correct Answer: C

Rationale: The correct answer is C (12.325 mL). To calculate this, first, convert 2.5 teaspoons to mL by multiplying by 4.93: 2.5 * 4.93 = 12.325 mL. Choice A (5.33 mL) is incorrect because it is less than the correct amount. Choice B (7.43 mL) is also incorrect as it is lower than the correct value. Choice D (0.507 mL) is incorrect because it is significantly lower than the correct amount. Therefore, the correct answer is C as it accurately reflects the conversion of teaspoons to milliliters based on the given conversion rate.

Correct Answer: A

Rationale: The correct answer is A: One. Any number raised to the power of zero equals one. This is because the rule for exponents states that any number raised to the power of zero is equal to one, regardless of the base number. This rule is derived from the properties of exponents and is a fundamental concept in mathematics. Choices B, C, and D are incorrect because raising a number to the power of zero does not result in the number itself, zero, or two. The key to remember is that any number raised to the power of zero is always equal to one, making choice A the correct answer.

Correct Answer: C

Rationale: The independent variable is the variable that is manipulated or changed in an equation. In the equation f(t)=4t+9, 't' is the independent variable because it represents the input value that we can freely choose or vary. We can substitute different values for 't' to see how it affects the output 'f(t)'. On the other hand, 'f' is the dependent variable as it depends on the value of 't'. The constant term '9' and the coefficient '4' are not variables, so they cannot be independent variables. Therefore, choice C (t) is the correct answer. Choices A, B, and D are incorrect because they do not represent the independent variable in the given equation.

Correct Answer: B

Rationale: The correct answer is B: Stocks. In this scenario, stocks are the independent variable because they are being manipulated or controlled to observe the effect on other variables like production, sales, and investments. Increasing stocks is the action taken, which then leads to the changes in production, sales, and investments. On the other hand, choices A, C, and D are dependent variables as they are influenced by the changes in stocks. Sales, production, and investments are all outcomes or results of the changes in stocks. Therefore, stocks are the independent variable in this situation.
