Answer:
$40
Step-by-step explanation:
Find the original price by dividing 28 by 0.7
28/0.7
= 40
So, the original price was $40
we need to identify the angle GFE
We will connect the yellow dots beside the point F which are on the line segments FG and FE
See the following picture:
A perpendicular slope is a slope that is the negative reciprocal of the current slope. Therefore, 3.
C = 2πr
r = radius
c = circumference = 18
Plug in the corresponding numbers with variables.
18 = 2πr
Isolate the r. Divide 2 and π from both sides
(18)/2π = (2πr)/2π
9/π = r
C/π = r is your formula to finding r.
