50% of 28 is 14 so 28+14= 42
The sales tax is 2$ Hope this is the answer you're looking for.
First, find the fraction of the circumference represented by central angle 7pi/8:
7pi/8
--------
2pi
Then find the circumference; it is C = 2 pi r, or 2pi(6), or 12 pi units
Then the arc length is 7pi/8 7
-------- * 12 pi = -------- units, or 21/4 units, or 5 1/4 units.
2pi 16 pi
m = change in y over change in x
m = (14-5)/(4-1)
m = 9/3 = 3
m = 3
Answer:
4 × 5 = 20
Step-by-step explanation:
Imagine this: the X is 4 and the Y is 5.
You want to find the area of it, so the equation would be
4 × 5 = 20
HOPE THIS WAS HELPFUL!!!!
