A worker earns $8000.00 per week before any tax deductions. The following taxes are deducted each week: $83.00 federal income tax, $38.00 state income tax, and $79.00 social security tax. How much will the worker make in 4 weeks after taxes are deducted?

  • A. $31,200.00
  • B. $29,200.00
  • C. $26,000.00
  • D. $24,000.00
Correct Answer: A

Rationale: To determine the worker's earnings in 4 weeks after taxes are deducted, start by calculating the total weekly tax deductions: $83.00 + $38.00 + $79.00 = $200.00. Subtract the total weekly tax deductions from the weekly earnings: $8000.00 - $200.00 = $7800.00. Now, to find the total earnings after 4 weeks, multiply the weekly earnings after deductions by 4: $7800.00 x 4 = $31,200.00. Therefore, the worker will make $31,200.00 in 4 weeks after taxes are deducted.

What is the metric equivalent of 7 inches in measurements used for appointments?

  • A. 3.2 cm
  • B. 17.8 cm
  • C. 15.4 cm
  • D. 2.8 cm
Correct Answer: B

Rationale: To convert inches to centimeters, you can use the conversion factor that 1 inch is equal to 2.54 centimeters. Therefore, 7 inches is equivalent to 7 * 2.54 = 17.78 cm, which is closest to 17.8 cm (Choice B). This conversion is commonly used in various fields to provide accurate measurements across different systems. In this case, for appointments, knowing the metric equivalent of inches is important for precise measurements and communication, ensuring accurate scheduling and planning.

Of the numbers listed above, which number is the greatest? The numbers are 2/3, -0.7, -1.3, and -4/3.

  • A. 2/3 (0.67)
  • B. -0.7 (-0.7)
  • C. -1.3 (-1.3)
  • D. -4/3 (-1.33)
Correct Answer: A

Rationale: To compare these numbers, convert them to a common form. 2/3 is equivalent to approximately 0.67. -0.7, -1.3, and -4/3 are negative numbers. Among these choices, 2/3 (0.67) is the only positive number, making it greater than all the negative numbers (-0.7, -1.3, -4/3). Therefore, 2/3 is the greatest number among the options provided.

What is an appropriate unit of measure to express the length of a dollar bill?

  • A. Meters
  • B. Decimeters
  • C. Kilometers
  • D. Centimeters
Correct Answer: D

Rationale: Dollar bills are relatively small items, so their length is commonly measured in centimeters. Meters, decimeters, and kilometers are much larger units of length, making centimeters the most suitable unit to accurately express the length of a dollar bill. Centimeters provide a more precise and practical measurement for the size of a dollar bill compared to the other options, which are more suitable for larger distances or objects.

There are 80 calories in one serving of salad dressing, and 87.5% of those calories are from fat. One serving of salad dressing is 2 tablespoons. Which of the following amounts is the number of calories from fat per tablespoon of salad dressing?

  • A. 40
  • B. 70
  • C. 35
  • D. 45
Correct Answer: A

Rationale: To find the calories from fat per tablespoon, first, calculate the total calories from fat: 80 calories * 0.875 = 70 calories from fat. Then, divide by the number of tablespoons in a serving (2): 70 / 2 = 35 calories per tablespoon. Therefore, the correct answer is 35 calories, which is closest to 40.

What is the best decimal approximation of 10 times the positive square root of 20?

  • A. 89.4
  • B. 200
  • C. 44.7
  • D. 100
Correct Answer: C

Rationale: To find 10 times the positive square root of 20, first calculate the square root of 20, which is approximately 4.472. Then, multiply this by 10: 10 * 4.472 ≈ 44.7. The best decimal approximation of 10 times the positive square root of 20 is 44.7, which corresponds to Option C.
