Answer: 29 Hours of Work
Step-by-step explanation: Let's start by working backwards.. We know that Ken makes 5 dollars an hour, and he worked 40 hours. 5 * 40 = 200, and 400-200 = 200. This means that Kim has to work 200/7 hours, or (approximately) 29 hours of work.
Answer:
25%
Step-by-step explanation:
The temperature starts at 85 degrees.
t = 85
After 1 minute, it loses 3.5 degrees.
t = 85 - 3.5
After 2 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 2
After 3 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 3
etc.
After 12 minutes, it loses another 3.5 times 12 degrees.
t = 85 - 3.5 * 12
