Answer:
The answer would be D.
Step-by-step explanation:
We know that
area of a circle=pi*r²-------> r=√[area/pi]
for area=5000 ft²
r=√[5000/pi]----> r=39.90 ft
39.90*2-----> 79.8 ft of diameter
79.8 ft is > 40 ft
therefore
the answer is
<span>No, he forgot to multiply the radius by 2.</span>
Answer:
A. 135 mi
Step-by-step explanation:
The distance on the map is 3 3/4 times the 1-inch scale reference, so the distance on the ground will be 3 3/4 times the corresponding 36-mile ground distance.
(3 3/4)(36 mi) = 135 mi
The distance between the cities is 135 mi in real life.
Answer:
- 4x^2-15x
Step-by-step explanation:
(f-g)(x) = f(x) - g(x) = - 3x^2-8x-x^2-7x = - 4x^2-15x
