Let's go through each question and verify the answers:
1. Are these answers correct:
Answer: 4.171
Explanation: The answer 4.0171 is incorrect. It should be written as a mixed number fraction, which is 4 171/10,000.
2. Arrange in order from smallest to largest:
Answer: 2.05, 2.051, 2.0513, 2.0515, 2.052, 2.059, 251/100, 25/10
Explanation: The numbers should be arranged in ascending order. Start with the decimals (2.05, 2.051, 2.0513, 2.0515, 2.052, 2.059), then the fractions (251/100, 25/10).
3. 45.6 – 8.75:
Answer: 36.85
Explanation: Subtract 8.75 from 45.6 to get the answer 36.85.
4. Add thirty-eight and nine tenths, five and fifty-eight hundredths, seven, and fifteen and eight tenths:
Answer: 59.86
Explanation: Add the numbers together: 38.9 + 5.58 + 7 + 15.8 = 59.86.
5. Claudia earns $6.40 per hour (h). For overtime (each hour over 40 h) she earns $9.60. If she works 48.5 h in a week, what pay should she receive?
Answer: $465.60
Explanation: To calculate the pay, multiply the regular hours by the regular rate and the overtime hours by the overtime rate, then add them together. (40 hours x $6.40) + (8.5 hours x $9.60) = $256 + $209 = $465.60.
6. To find the simple interest on a loan for 1 year at 12.5%, multiply the amount of the loan by 0.125. What simple interest will you pay on a loan of $1,458 at 12.5% for a year?
Answer: $182.25
Explanation: Multiply the loan amount ($1,458) by the interest rate (12.5% or 0.125) to get the simple interest: $1,458 x 0.125 = $182.25.
7. In a bottling company, a machine can fill a 2 liter (l) bottle in 0.5 second (s) and move the next bottle into place in 0.1 s. How many 2-l bottles can be filled by the machine in 2 hours?
Answer: 1.00 or 0.20
Explanation: First, convert 2 hours to seconds: 2 hours x 60 minutes x 60 seconds = 7,200 seconds. Now, calculate how many bottles can be filled in that time: (7,200 seconds / (0.5 seconds + 0.1 seconds)) = 7,200 seconds / 0.6 seconds = 12,000 bottles. However, it seems there was a typo in the answer choices, as the correct answer should be 12,000 bottles, not 1.00 or 0.20.
