How many shipping labels are needed each day if 9 boxes are shipped, with each box requiring 3 shipping labels?
- A. 7
- B. 3
- C. 27
- D. 24
Correct Answer: C
Rationale: To find the total number of shipping labels required, multiply the number of boxes by the number of shipping labels per box. With 9 boxes shipped and 3 shipping labels needed per box, the calculation is: 9 boxes x 3 labels per box = 27 shipping labels needed each day. Therefore, the correct answer is C, as a total of 27 shipping labels are required daily.
A dairy farmer wants to measure the milk production of his cows. He determines that the herd has produced a total of 250 gallons of milk this morning. How many quarts is this? (Enter numeric value only.)
- A. 500
- B. 750
- C. 1000
- D. 1250
Correct Answer: C
Rationale: The correct answer is C: 1000 quarts. To convert gallons to quarts, you need to know that 1 gallon is equal to 4 quarts. Therefore, to convert 250 gallons to quarts, you would multiply 250 by 4, which equals 1000 quarts. Choice A (500 quarts), B (750 quarts), and D (1250 quarts) are incorrect because they do not correctly convert the given amount of gallons to quarts. Be sure to always remember the conversion factor of 1 gallon to 4 quarts when solving such conversion problems.
Ratio and proportion: 0.1:10::x:400
- A. 5
- B. 4
- C. 25
- D. 50
Correct Answer: B
Rationale: In a ratio, the two parts are related by a proportion. To find the missing value, x, in the given ratio, you need to set up a proportion. Given: 0.1:10::x:400. Cross multiply to solve for x: 0.1 * 400 = 10 * x, which simplifies to x = (0.1 * 400) / 10 = 4. Therefore, the correct answer is 4.
Change the fraction to the simplest possible ratio: 8/14
- A. 2:4
- B. 4:7
- C. 4:6
- D. 3:5
Correct Answer: B
Rationale: To simplify the fraction 8/14, you need to divide both the numerator and denominator by their greatest common factor, which in this case is 2. Dividing both 8 and 14 by 2 results in 4/7, which is the simplest ratio for 8/14. Therefore, the correct answer is 4:7. Remember, when simplifying fractions, always divide both the numerator and denominator by their greatest common factor to represent the fraction in its simplest form.
Convert 11:32 A.M. to Military time. (Enter the numerical value only.)
- A. 1132
- B. 1232
- C. 1032
- D. 1112
Correct Answer: A
Rationale: To convert 11:32 A.M. to Military time, A.M. hours from 1:00 to 11:59 are represented with a leading zero if required. In the 24-hour clock system, 11:32 A.M. is correctly converted to 1132. The correct answer is option A, as it represents 11:32 A.M. in the correct 24-hour time format. Remember that in military time, the hours are always represented with two digits, so a leading zero is added if the hour is a single digit to maintain consistency.
