Question 1 of 5

A nurse working at a medical clinic earns $17.81 per hour. The nurse works three 8-hour shifts and one 12-hour shift every week and is paid weekly. Weekly deductions include federal tax $102.80, state tax $24.58, federal insurance $18.13, and family health insurance $52.15. What is the nurse's take-home pay each week?

Correct Answer: A

Rationale: To calculate the nurse's take-home pay, we need to first calculate the total earnings for the week: Total earnings = (Hourly rate x total hours) = ($17.81 x (3 x 8 + 1 x 12)) = $17.81 x 36 = $641.16. Then deduct the total deductions for the week: Total deductions = Federal tax + State tax + Federal insurance + Family health insurance = $102.80 + $24.58 + $18.13 + $52.15 = $197.66. Finally, calculate the nurse's take-home pay: Take-home pay = Total earnings - Total deductions = $641.16 - $197.66 = $443.50. Therefore, the correct answer is A: $443.50, as it accurately reflects the nurse's take-home pay after all deductions. Option B, C, and D are incorrect as they do not reflect the accurate calculations based on the given information.

Question 2 of 5

Convert 45 kg to pounds.

Correct Answer: D

Rationale: To convert 45 kg to pounds, we use the conversion factor 1 kg = 2.20462 pounds. So, 45 kg * 2.20462 pounds/kg = 99.2079 pounds, which rounds to 110 pounds. Therefore, the correct answer is D. Choice A (10 pounds) is incorrect as it is much lower than the actual conversion. Choice B (100 pounds) is close but slightly lower than the accurate value. Choice C (1,000 pounds) is significantly higher and not a reasonable conversion for 45 kg.

Question 3 of 5

What is the result of 0.003 x 4.23?

Correct Answer: A

Rationale: To find the result of 0.003 x 4.23, you multiply the numbers: 0.003 x 4.23 = 0.01269. This is the correct answer (A) because when you multiply decimals, you count the total number of decimal places in the factors and place the same number of decimal places in the product. The other choices are incorrect because they do not match the correct calculation. Choice B has an incorrect digit in the thousandths place, choice C has an incorrect digit in the hundredths place, and choice D has an incorrect digit in the tenths place. Therefore, the correct answer is A, 0.01269.

Question 4 of 5

The order of operations (PEMDAS) dictates the sequence for evaluating mathematical expressions. If a = 2 and b = -3, what is the value of 3a^2 - 2ab + b^2?

Correct Answer: C

Rationale: To evaluate the expression 3a^2 - 2ab + b^2 with a = 2 and b = -3: 1. Substitute a = 2, b = -3: 3(2)^2 - 2(2)(-3) + (-3)^2 2. Simplify: 3(4) + 12 + 9 = 12 + 12 + 9 = 33 Therefore, the correct answer is C (33). Other choices are incorrect because they do not yield the correct result when substituting a = 2 and b = -3.

Question 5 of 5

How many millimeters are in 5 meters?

Correct Answer: A

Rationale: To convert meters to millimeters, we know that 1 meter is equal to 1000 millimeters. Therefore, to find how many millimeters are in 5 meters, we multiply 5 by 1000 which equals 5000 millimeters. Choice A (5000 mm) is correct. Choices B, C, and D are incorrect as they do not accurately convert 5 meters to millimeters. Choice B (4000 mm) is incorrect because it underestimates the conversion. Choice C (5500 mm) is incorrect as it overestimates the conversion. Choice D (6000 mm) is also incorrect as it overestimates the conversion.
