Answer:
7.5 < x≤10.5
Step-by-step explanation:
14<2x−1≤20
Add 1 to all sides
14+1<2x−1+1≤20+1
15<2x≤21
Divide each side by 2
15/2 <2x/2 ≤21/2
7.5 < x≤10.5

Step-by-step explanation:
Area of the shaded region is 540 – 65.25π.
Solution:
Length of the rectangle = 12 + 9 + 6 + 3 = 30 in
Width of the rectangle = 18 in
Radius of the larger circle (
) = 12 ÷ 2 = 6 in
Radius of the medium circle (
) = 9 ÷ 2 = 4.5 in
Radius of the smaller circle (
) = 6 ÷ 2 = 3 in
Area of the shaded region = Area of the rectangle – Area of the larger circle – Area of the medium circle – Area of the smaller circle




Area of the shaded region is 540 – 65.25π.
Complementary angles equal 90 degrees. The ratio is 2:3.
2+3=5
90/5=18
2(18):3(18)
36 degrees, 54 degrees
