TEAS Math Questions Questions
Question 1 of 5
If you have a rectangle with a width of 5 inches and a length of 10 inches and scale it by a factor of 2, what will the new perimeter be?
Correct Answer: C
Rationale: When a rectangle is scaled by a factor of 2, both the length and width are multiplied by 2. The new dimensions become width = 5 * 2 = 10 inches and length = 10 * 2 = 20 inches.
Therefore, the new perimeter is calculated as 2 * (10 + 20) = 60 inches.
Choice A, B, and D are incorrect as they do not reflect the correct calculation based on scaling the dimensions of the rectangle.
Question 2 of 5
Veronica is making a holiday schedule. 35% of staff members will be on vacation, and 20% of the remainder are certified to work. What percentage of the staff is certified and available?
Correct Answer: A
Rationale:
To find the percentage of staff certified and available, we first calculate the percentage of staff members not on vacation, which is 100% - 35% = 65%.
Then, 20% of this group is certified to work, which is 20% of 65% = 0.20 * 65% = 13%.
Therefore, Veronica has 13% of the staff certified and available to work. The correct answer is 0.13 (or 13%).
Choice C (0.65) is incorrect because it represents the percentage of staff members not on vacation, not the percentage that is certified and available.
Choice D (0.8) is incorrect as it is not the correct percentage of staff members certified and available.
Choice B (0.13) is the correct answer, not choice A (0.07), as 0.07 represents 7%, not 13%.
Question 3 of 5
A store offers a 15% discount on all items. If an item costs $100, what is the price after the discount?
Correct Answer: B
Rationale:
To calculate the price after the 15% discount on a $100 item, you first find 15% of $100, which is $15.
Then, subtract $15 from the original price: $100 - $15 = $85.
Therefore, the correct answer is $85.
Choice A ($90),
Choice C ($80), and
Choice D ($75) are incorrect as they do not reflect the correct calculation of applying a 15% discount to the original $100 price.
Question 4 of 5
What percentage of the staff is certified and available to work in the neonatal unit during the holiday if 35% are on vacation and 20% of the remainder are certified?
Correct Answer: A
Rationale: After 35% of the staff are on vacation, 65% remain. Since 20% of the remaining staff are certified, you multiply 0.20 by 65% (0.20 * 65% = 0.13 or 13%).
Therefore, the correct answer is 0.13 or 13%.
Choices C and D are incorrect as they do not represent the correct calculation for the percentage of certified staff available.
Choice B is incorrect because it incorrectly states the calculated percentage as 0.13 instead of 0.07.
Question 5 of 5
In a study about anorexia conducted on 100 patients, where 70% were women, and 10% of the men were overweight as children, how many male patients in the study were NOT overweight as children?
Correct Answer: C
Rationale: Out of the 100 patients, 30% were men (100 - 70% women), hence 30 men. Since 10% of the men were overweight as children (10% of 30 is 3), the remaining men (30 - 3) were NOT overweight as children, which equals 27.
Therefore, the correct answer is 27.
Choices A, B, and D are incorrect because they do not reflect the accurate calculation of the number of male patients who were NOT overweight as children.
