7 - (16 - 10) + n = 10
7 - (6) + n = 10
1 + n = 10
n = 9
Answer:
16.28
Step-by-step explanation:
a^2 + b^2 = c^2
11^2 + 12^2 = c^2
121 + 144 = 265
sq root 265
is about 16.28
H=36in
d=30in
V=?
________
V=πR²h=π(
)²h=π*15²30=π225*30=6750π (~20250in³)
Answer: V of fish tank is 6750π in³ (~20250 in³)
Answer:
Step-by-step explanation:
So initially you have a square piece of metal, 15" x 15". You cut out squares from the corners of each side with side length x.
So you'll have a sheet that looks something like this now (assuming the formatting works):
_____
__| |__
| |
|__ __|
|____|
Your original side length was 15, but it has now been reduced by x on each side, so you're now going to have a new side length of 15 - 2x
When you fold the box up, the box will have a height of just x.
So you have a base with lengths (15 - 2x) and (15 - 2x), and a height which is just x.
V = l*w*h
So
V = (15 - 2x)(15 - 2x)(x)
= 225x - 60x^2 + 4x^3
Hope this helps
Well 12 divided by 6 is 2 so what do you think would be the easiest model to make
