TEAS 7 Math Practice Test

Correct Answer: D

Rationale: The product of two even integers and one odd integer will always be an even integer. This is because multiplying any number of even integers together results in an even number, and multiplying any number of odd integers together also results in an odd number. Therefore, the product could not be 3.75 (odd), 9 (odd), or 16.2 (even non-integer). The only possible option is 24, as it is an even integer and can be obtained by multiplying two even integers and one odd integer together.

Correct Answer: B

Rationale: To calculate the number of tanks Robert needs, we divide the total distance by the car's mileage per tank: 1800 miles / 30 miles per gallon = 60 gallons needed. Since his tank holds 12 gallons, we divide the total gallons needed by the gallons per tank: 60 gallons / 12 gallons per tank = 5 tanks. Therefore, the correct answer is B: 5 tanks. Choice A (3 tanks) is incorrect because it doesn't consider the total distance. Choices C (30 tanks) and D (60 tanks) are incorrect as they grossly overestimate the number of tanks needed.

Correct Answer: D

Rationale: The correct answer is D: 0.16%. To find the percentage equivalent of a decimal, we multiply the decimal by 100. So, 0.0016 x 100 = 0.16%. Choice A (16%) is incorrect because it represents the decimal as a whole number, not a percentage. Choice B (160%) is incorrect as it incorrectly multiplies the decimal by 1000 instead of 100. Choice C (1.60%) is incorrect as it incorrectly places the decimal point in the wrong position, resulting in an incorrect percentage value.

Correct Answer: C

Rationale: To determine the correct dosage, multiply the patient's weight (60 kg) by the prescribed dosage (5 mg/kg): 60 kg x 5 mg/kg = 300 mg. Choice C is correct. Choices A, B, and D are incorrect as they do not result from the correct calculation. Choice A (100 mg) is too low, Choice B (150 mg) is also too low, and Choice D (400 mg) is too high based on the calculation.

Correct Answer: B

Rationale: Correct Answer: B ($48,443) Rationale: To find the total price of Veronica's new car, add the base price ($40,210) to the cost of the surround sound system ($3,015) and the maintenance package ($5,218). Therefore, $40,210 + $3,015 + $5,218 = $48,443. Summary of other choices: A: $50,210 - Incorrect as it only includes the base price of the car. C: $43,225 - Incorrect as it only includes the base price and the maintenance package. D: $40,210 - Incorrect as it only includes the base price of the car.
