Answer:
3/8
Step-by-step explanation:
75% or 0.75 is equivalent to 3/4
3/4 times 1/2 equals 3/8
0.05(0.85y)=5%(of the onsale dvd)
and a is just the on sale dvd (85%)
Ok so the first one is
1.x=135
2.x=-23
3.x=3
4.x=70
Answer:
Correct answer: Fourth answer As = 73.06 m²
Step-by-step explanation:
Given:
Radius of circle R = 16 m
Angle of circular section θ = π/2
The area of a segment is obtained by subtracting from the area of the circular section the area of an right-angled right triangle.
We calculate the circular section area using the formula:
Acs = R²· θ / 2
We calculate the area of an right-angled right triangle using the formula:
Art = R² / 2
The area of a segment is:
As = Acs - Art = R²· θ / 2 - R² / 2 = R² / 2 ( θ - 1)
As = 16² / 2 · ( π/2 - 1) = 256 / 2 · ( 1.570796 - 1) = 128 · 0.570796 = 73.06 m²
As = 73.06 m²
