Answer: Well i think its 18
Step-by-step explanation:
Answer:
1. 9x = 63
Step-by-step explanation:
9x = 63
if x=7, then 9(7) = 63
9*7=63
63 = 63
Answer:
Domain > 0, Range C(x) > 2
Step-by-step explanation:
x is the distance, distance is always large than 0 => x > 0
=> Domain x > 0
Multiply both sides by 0.75
=> 0.75x > 0
Add both sides by 2
=> 0.75x + 2 > 0 + 2
=> 0.75x + 2 > 2
=> Range C(x) = 0.75x + 2 > 2
D, because there might be values higher than 120, because the data points range from 0 - 200.
We know that
Area of a regular polygon = (1/2)*apothem<span>*perimeter
</span>perimeter <span>of the regular decagon=10*a
where
a is the length side of the decagon
in this problem
a=1.8 ft
so
</span>perimeter of the regular decagon=10*1.8----> 18 ft
Area of a regular decagon = (1/2)*2.8*18----> 25.2 ft²
<span>Round to the nearest whole number------> 25 ft</span>²
the answer is
25 ft²
