About 115°
Step-by-step explanation:
- By 2 pi r, total circumference is about 942
- Length of an arc = 2 pi r (theta/360)
- We needed to find theta(angle) here
- Easily putting all the values gives us 115°
Answer:
23d + 45 = 137
Explanation:
Since it is $23 per day, that dollar amount must be associated with a variable that multiples it per day that it is rented. Finally, you need to add the one time $45. This equation can then be used to find how many days it was rented for.
23d + 45 = 137
23d = 92 (Subtract 45 from both sides)
d = 4 (Divide by 23 on both sides)
The rug-cleaning machine was rented for 4 days. You found this using the equation: 23d + 45 = 137
