Answer:
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the sector minus the area of the triangle
step 1
Find the area of the circle
the area of the circle is equal to
we have
substitute
step 2
Find the area of the sector
we know that
The area of the circle subtends a central angle of 360 degrees
so
by proportion find out the area of a sector by a central angle of 72 degrees
step 3
Find the area of triangle
The area of the triangle is equal to
step 4
Find the area of the shaded region
Subtract the area of the triangle from the area of the sector
Answer:
in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do

Answer:
3w+7
Step-by-step explanation:
Let's simplify step-by-step.
8v+w+7−8v+2w
=8v+w+7+−8v+2w
Combine Like Terms:
=8v+w+7+−8v+2w
=(8v+−8v)+(w+2w)+(7)
=3w+7
Answer:
See below
Step-by-step explanation:
I'm guessing you want to fill in the blanks of the sequence?
We can represent this as an equation:
31-3x=18
-3x=13
x=-13/3
Second term: 31 - (13/3) = 26 2/3
Third term: 26 2/3 - (13/3) = 22 1/3
Answer: 3.75 ft
Step-by-step explanation:
Here we are given the measure of the length of a window. Generally the length is given in the International System of units format (meters); however, in this case we are given the length in feet and inches:
Now, before converting this whole measure to feet, we have to know that 
, then we can perform the conversion:
This means 
Hence:
This is the measure of the length of the window in feet.
