Answer:
85
Step-by-step explanation:
12 in = 1 ft
first you need to convert 60ft to in:
60 * 12 = 720in
then divide 720(the amount of space you are covering by 8.5
720/8.5 = 84.7
then i guess you can round it to a full revolution so it would be 85
Answer:
1a: 6.283
b: 51.313
c: 285.1
Step-by-step explanation:
Area of a sector = (angle/360)πr²
1a
Area=(45/360)π(4²)=6.283
b
Area=(120/360)π(7²)=51.313
c
Area=(270/360)π(11²)=285.1
Answer:

Step-by-step explanation:
<h3>
I will use the elimination method.</h3>
We want to make the X's the same:
Because the signs of the X's are the same we subtract the 2 equations to make:
(I put the second one on top of the 1st)
So:
Substitute y into either equation 1 or 2:
(I chose equation 1)
So:
Answer:
B multiplying by
Step-by-step explanation:
Multiple is opposite from divide.
Plus is opposite from subtract.
