A full circle has a circumference of 2πr and an angle of 2π radians.
Set up a proportion:
2πr - 2π rad
2r - x rad
The answer is D. 2 radians.
Hello there!
Here is the answer worked out for you!
12x[-1+sqrt(5)]
-12x+12xsqrt(5)
Remember that you can only add like terms so you can't add -12x to 12xsqrt(5). The radical makes it an unlike term.
I hope this helped and best wishes!
The average daily balance for the month was $84.21, and the finance charge for the month was $30.13.
<h3><u>Averages</u></h3>
Given that Sally's balance on her credit card is $75.00 on the first day of August, and she makes a payment of $18.00 on August 17 and a new purchase of $41.00 on August 29, and the annual interest rate is 21.25%, to determine what is Sally's average daily balance and finance charge for the month of August, the following calculation must be made:
- 75 x ((21.15/12 x 16) / 100) + 75 = A = 86.89
- 57 x ((21.15/12 x 13) / 100) + 57 = B = 70.06
- 98 x ((21.15/12 x 3) / 100) + 98 = C = 103.18
- (86.89 x 16 + 70.06 x 13 + 103.18 x 3) / 31 = X
- 84.21 = X
- 86.89 + 70.06 + 103.18 - 75 - 57 - 98 = Y
- 30.13 = Y
Therefore, the average daily balance for the month was $84.21, and the finance charge for the month was $30.13.

Answer: 286 minutes
Step-by-step explanation:
x : # of months that has gone by
0.24x : cost of the 24 cent plan after "x" minutes
39.95 + 0.10x : cost of the 10 cent plan after "x" minutes
1. 39.95 + 0.10x > 0.24x
2. 39.95 > 0.24x - 0.10x
3. 39.95 > 0.14x
4. 285.36 > x
x must be AT LEAST 286 minutes for plan #2 (39.95 + 0.10x) to be a better deal
You know that a straight line has an angle of 180 degrees;
48+x+x=180 <-- since they are all on the same time
48+2x=180
2x=180-48
2x=132
x=132/2
x=66
Therefore, the x value is 66 degree.
Hope I helped :)
