TEAS Practice Test Math

Correct Answer: B

Rationale: To find the number of students in the respiratory care program, we need to calculate the percentage of students in that program based on the pie chart. The respiratory care program occupies 19% of the pie chart. 19% of 800 students is 0.19 * 800 = 152. Therefore, the correct answer is B: 152. Choice A (336) is incorrect as it represents the percentage of students in a different program, not respiratory care. Choice C (144) and Choice D (168) are also incorrect as they do not correspond to the percentage allocated for the respiratory care program in the pie chart.

Correct Answer: B

Correct Answer: C

Rationale: To convert a percentage to a decimal, you divide by 100. In this case, 87.5% divided by 100 is 0.875. Therefore, choice C, 0.875, is the correct decimal form of 87.5%. Choices A and B are incorrect as they do not represent the correct decimal value. Choice D, 8.75, is also incorrect as it is the decimal form of 875%.

Correct Answer: C

Rationale: The correct answer is C: Dependent. In this study, the weight of the babies is the variable being measured and studied in relation to different time intervals after birth. The weight of the babies depends on the time intervals, making it the dependent variable. Other choices are incorrect because: A: Independent variable is the variable that is manipulated or controlled by the researcher, in this case, time intervals are the independent variable. B: Control variable is a variable that is kept constant to prevent it from influencing the results, weight is not a control variable. D: Constant is not applicable in this context as weight is not a constant value in the study, it varies with time intervals.

Correct Answer: C

Rationale: To find out how much ammonia is needed, we first calculate the total amount of ammonia needed for 230 gallons of solution. Since 1 gallon requires 6 oz of ammonia, for 230 gallons, we multiply: 230 (gallons) x 6 (oz) = 1380 oz of ammonia. Therefore, the correct answer is C: 1380 oz. Other choices are incorrect because: A: 1380 gallons - This does not make sense as we are calculating the amount of ammonia, not the total volume of cleaning solution. B: 6900 gallons - This is not a logical calculation based on the given information. D: 1400 oz - This is close to the correct answer but miscalculates the total amount of ammonia required.
