Step-by-step explanation:
11. shape 1 => A = ½×17×10=85m²
shape 2=> A = 17×9 =153 m²
total area = 238 m²
12. shape 1 => A = 7×3= 21 m²
shape 2=> A = 3×2 = 6 m²
total area = 27 m²
1. D - Since it's random, everyone has an equal chance of being picked
2. B - Since the people are already registered voters it would be easier to get a response from them. Plus, picking ever 10th person makes it random.
3. false - a fair question wouldn't make assumptions about the population
4. B - "Don't you think" causes the answerer to be pushed towards saying yes
hope this helps :)
Step-by-step explanation:
- -7.2(x-15.6)= -9
- -7.2x+112.32= -9
- -7.2x= -9-112.32
- -7.2x= -121.32
- x= -121.32/ -7.2
- x=16.85

The formula for volume of a cone is V=(1/3)*h*π*(r^2)
our height is 7.5 feet, and since the length of the base of the cone (diameter) is 22 feet long, the radius is 11 feet long.
(1/3)*7.5*π*(11^2)=302.5*π=950.3
so the volume of the house is about 950 feet cubed.
