Divide 68 by 85 = is .8 which is 80%
3(r-6)+2=4(r+2)-21
3r-18+2=4r+8-21
3r-16=4r-13
-3=r
r=-3
Infinite intervals are closed if they contain a finite endpoint, and open otherwise. The entire real line is an infinite interval that is both open and closed
The figure is made up of two semi-circles and one triangle
--------------------------------
Find Radius
--------------------------------
Radius = Diameter ÷ 2
Radius = 5 ÷ 2
Radius = 2.5 ft
Area of the semi-circle = 1/2 πr²
Area of the semi-circle = 1/2 x π x (2.5)²
Area of the semi-circle = 9.82 ft²
Area of the triangle= 1/2 x base x height
Area of the triangle = 1/2 x 6 x 4
Area of the triangle = 12 ft²
Total area = 9.82 + 9.82 + 12
Total area = 31.63 ft²
--------------------------------------------
Total Area = 31.63 ft²
--------------------------------------------
Answer:
-3
Step-by-step explanation:
2^2 = 4
4 + (-3) = 1
4*2 = 8
8 * -1 = -8
-8 / 2 = -4
1 + -4 = -3
