Answer:
D. -14
Step-by-step explanation:
We need to solve for the radius
circumference = radius * 2 * PI
radius = circumference / (2*PI)
radius = 4.5 / (

Answer:
4
Step-by-step explanation:
2+2 is 4
Answer:
The nearest 100,000 of 89,678 would be 100,000.
Step-by-step explanation:
For me to simply put this, ignore the digits behind the commas.
You'll have 89, and imagine you have to get it to the nearest 100.
So when rounding / estimating, if the digit you're talking about is above 5, you round up. If it is below 5, you round down.
Since you have 89, you'd round up to a 100 because 89 is over 50.
Therefore you'd have 100,000 if you're rounding 89,678 to the nearest hundred thousand.
Answer:
work will be explained in the explanation portion
1. x = 3
2. y = 5
3. x = 13
4. y = 2
5. c = 7
6. a = 34
7. unsure but -5/12
8. 16
Step-by-step explanation:
1. 11 - 8 = 3
2. 16 + 9 = 25 5 x 5 = 25
3. 9 + 4 = 13
4. 10 - 4 = 6 3 x 2 = 6
5. 45 - 3 = 42 6 x 7 = 42
6. 23 + 11 = 34
7. 2/3 = 8/12 1/4 = 3/12 8/12 - 3/12 = 5/12
8. 14 divided by 7/8 = 16 (use keep change flip)
HOPE THIS HELPS!! <33
