B. 7 because 24 + 24 = 48 meaning 6 cars have been washed within 48 mins. 1 car can be washed in 8 mins. 48 + 8 = 56
Ok so to answer this, we first need to figure out the area of both circles
we will use the formula A=πr²
so our two areas end up being 121π and 81π
now all we do is subtract the smaller from the larger
121π - 81π = 40π
shaded region = 40π
The answer to the question ought to be 10
Answer:
x=17/11
Step-by-step explanation:
1. 7−3(x−4)=2(4x+1)
2. −3x+19=8x+2
3. −3x+19−8x=8x+2−8x
4.−11x+19=2
5. −11x+19−19=2−19
6.x=(17/11)
Hope this helps :)
