Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A. To distinguish between the three types of graphs in scatterplots, look at the patterns. Linear graphs show a straight line, quadratic graphs show a U-shape, and exponential graphs rise or fall quickly in one direction. This is because linear relationships have a constant rate of change, quadratic relationships have a squared relationship, and exponential relationships have a constant ratio of change. Choice B is incorrect as it does not accurately describe the characteristics of each graph type. Choice C is incorrect as it mentions zigzag lines for linear graphs, which is not a typical characteristic. Choice D is incorrect as it describes a W-shape for quadratic graphs, which is not accurate. Overall, choice A provides a clear and accurate description of how to distinguish between linear, quadratic, and exponential graphs in scatterplots.

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS/BODMAS). First, we calculate the multiplication and division from left to right: 6 + 7 = 13, 13 - 4 = 9, 9 * 2 = 18. So, the correct answer is 18. Choice A is incorrect because it is the result of multiplying all the numbers together. Choice C is incorrect as it is the result of adding all the numbers together. Choice D is incorrect as it is the result of adding the first two numbers and then multiplying by the last two numbers.

Correct Answer: B

Rationale: The correct answer is B (0.23). To find the percentage donated to support construction, we need to subtract the percentage that went towards construction costs from 100% (total). Therefore, 100% - 23% = 77%. This means that 77% of the funds were donated to support construction. Choice A (0.49), C (0.18), and D (0.1) are incorrect because they do not represent the correct percentage of funds donated to support construction after deducting the construction costs.

Correct Answer: A

Rationale: The correct answer is A: Feet are larger; 1 foot is 0.3048 meters. To determine which is larger, we need to compare the conversion factor. 1 foot is equal to 0.3048 meters, indicating that a foot is smaller than a meter. Therefore, meters are larger than feet. Choice B is incorrect because 1 meter is equivalent to 3.28 feet, showing that a meter is larger. Choice C is incorrect as 1 foot is not 0.5 meters, and Choice D is incorrect as 1 meter is not 2 feet.

Correct Answer: C

Rationale: The correct answer is C: 8 pints. There are 8 pints in a gallon because 1 gallon is equivalent to 8 pints. This conversion is based on the fact that a gallon is defined as 128 fluid ounces and a pint is 16 fluid ounces, so 128/16 = 8 pints in a gallon. Choice A (2 pints) is incorrect because it does not correspond to the correct conversion. Choice B (4 pints) is incorrect as it is half of the correct answer. Choice D (16 pints) is incorrect as it represents the total number of fluid ounces in a gallon, not the number of pints.
