Math Practice TEAS Test

Correct Answer: B

Rationale: The correct answer is B: 16 ounces. There are 16 ounces in a pound because this is the standard conversion rate between ounces and pounds. To arrive at this conversion, we can use the fact that 1 pound is equal to 16 ounces. Therefore, if you have 1 pound and you want to convert it to ounces, you would multiply 1 pound by 16 ounces/pound, which gives you 16 ounces. Summary of other choices: A: 8 ounces - This is incorrect because 8 ounces is half of a pound, not the full conversion rate. C: 32 ounces - This is incorrect because 32 ounces is actually equivalent to 2 pounds, not 1 pound. D: 12 ounces - This is incorrect as it is not the standard conversion rate between ounces and pounds.

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: C

Rationale: To find the percentage of the time Cora did not fall, we subtract the number of times she fell (20) from the total times she skated (27). So, 27 - 20 = 7 times she did not fall. Then, we divide the number of times she did not fall (7) by the total times she skated (27), which is 7/27 ≈ 0.26 or 26%. Therefore, the correct answer is C. Choice A, B, and D are incorrect because they do not accurately represent the percentage of the time Cora did not fall based on the given information.

Correct Answer: B

Rationale: To solve the equation, we follow the order of operations: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Step 1: 5 + 3 = 8 Step 2: 4 - 6 = -2 Step 3: -2 / 2 = -1 Step 4: 8 - 1 = 7 Therefore, the correct answer is 7 (Option D). Option A is incorrect as it does not consider all operations. Option C is incorrect as it does not correctly follow the order of operations. Option D is incorrect as it does not correctly calculate the result.

Correct Answer: B

Rationale: To calculate the probability of consecutively pulling two more orange blocks, we first find the probability of pulling one orange block (3/12) and then the probability of pulling another orange block out of the remaining orange blocks (2/11). Multiplying these probabilities gives (3/12) * (2/11) = 6/132 = 3/55. Therefore, the correct answer is B. Choice A (3/12) is the probability of pulling one orange block, but it doesn't account for the second draw. Choice C (2/10) is incorrect as it doesn't consider the changing probabilities after the first draw. Choice D (1/3) is the probability of pulling one orange block only.
