Answer:
C: 12.5
Step-by-step explanation:
The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.
First we can set up our equation
Next we can solve for x by multiplying by x and dividing by 
There are 360 degrees in a circle, and we have 18 pieces, so we need to see how many times 18 goes into 360. We can find this out by dividing.
360/18=20
You can check this by multiplying 20 and 18 (it equals 360)!
So, each fraction of the circle will be 20 degrees.
If you take 5 of these 20 degree pieces, you'll need to multiply them by 20 to see how many degrees they'd be.
You need to multiply by 20 because each piece is 20 degrees, and we need to find how many degrees 5 pieces is. It's the same as doing
20+20+20+20+20! :)
20*5=100. 5 parts will be 100 degrees.
Hope I helped! :)
Just divide 100% by 80% and multiply that answer by 5. I'm pretty sure that's how you do it.
Answer:
26 1/4 miles
Step-by-step explanation:
9+4+12=25
1/2+3/4=1 1/4
25+1 1/4= 26 1/4
6x=2x+48
-2 -2
4x + 48
divide bot numbers by 4. X is by itself and then you will have x=24
