Answer:
59.5 feet
Step-by-step explanation:
Set up a proportion
Tree 1
17 feet tall
10 feet shadow
Tree 2
35 feet tall
x feet shadow
17/10= 35/x
(17)(35)= (10)(x)
595= 10x
/10 /10
59.5= x
The cast shadow of the second tree is 59.5 feet
Hey i took this and i got a hundred so :) 1) 3.2 and
2) 10.9
3) 15
4)27
hope this helped you :)
Just plug in 3 for n and then 5 for n to see if an turns out to be 10 and 26.
n=3:
A) an = 8*3+10 = 34
B) an = 8*3 - 14 = 10 OK
C) an = 16*3+10 = 58
D) an = 16*3 - 38 = 10 OK
n=5:
B) an = 8*5-14 = 26 OK
D) an = 16*5 - 38 = 42
So the answer is B
Answer:
Volume: 864
Surface Area: 684
Step-by-step explanation:
Volume:

Surface-Area: (Pretty Self-explanatory)
1. Triangles - 12 * 9 = 108 (You don't need to divide it by two, just leave it as is because there are two of these triangles.)
2. Base - 16 * 9 = 144
3. Height/Base - 12 * 16 = 192
4. 15 * 16 = 240
192 + 144 + 108 + 240 = 444
The Surface Area is 684.
