Hope this helps!
in 1980 it was about 20%
in 1990 it was about 30%
about a 10% increase
in 2000 it was just under 40% so almost a 10% increase
so for estimating you can say it is increasing by about 10% every 10 years
so in 2010 you can estimate about 50% are unmarried
Answer:
Solution given:
Area of parking space [parallelogram]=290ft²
base*height=290
base=290/29
base:10ft
Area of rectangular dimensions=11*7.4=81.4ft²

Answer:
The ratio of the length of DE and the length of BC = 1/4
Step-by-step explanation:
From the figure we can see two sectors
<u>To find the length of BC</u>
The sector ABC with radius r and central angle 2β
BC = (2πr)( 2β/360)
= 4πrβ/360
<u>To find the length of DE</u>
The sector ADE with radius r/2 and central angle β
DE = (2πr/2)( β/360)
= πrβ/360
<u>To find the ratio of DE to BC</u>
DE/BC =πrβ/360 ÷ 4πrβ/360
= πrβ/360 * 360/ 4πrβ
=1/4
