Answer:
The answer is D, 47.1.
Step-by-step explanation:
Circumference is the diameter multiplied by pi, 15 * 3.14 is 47.1, so your current choice is correct.
0.47460844803037 this is the answer
It would take 5 yrs. for both trees to be the same height.
Step-by-step explanation:
In the first part, he was travelling with twice the speed, or Vs, for distance
48 - d, for 2 hours.
speed = distance/time
distance = speed * time
First part :
48 - d = 2V * 2
⇒d + 4V = 48
Second part:
d = V * 2
⇒d = 2V
Substitute 2s for d in equation 1.
2s + 4s = 48
6s = 48
s = 8
The speed in the second part is 8 mph.
<u>The speed in the first part is 2s = 2(8) = 16</u>

Answer:
(x, y) = (-1, 1)
Step-by-step explanation:
8x + y = −7
for y = 1
8x + 1 = -7
subtract 1 from boh sides
8x = -8
divide bot sides by 8
x = -1
(x, y) = (-1, 1)
