Answer:
i just need points srry for wasting your time
Step-by-step explanation:
Both cylinder are similar
Volume of a cylinder is πr^2h
if we consider both has same radius as they are similar
Lets say V1 is volume of small cylinder and V2 is volume of big cylinder.
V1/V2=πr^2x5/πr^2xh
125/343=5/h
0.36=5/h
h=5/0.36
h=13.72 ft
Answer:
9 ft
Step-by-step explanation:
Let x represent the shortest piece. Then the sum of lengths is ...
x + (x +25) +3x = 40
5x = 15
x = 3
3x = 9
The third piece is 9 feet long.
_____
<em>Check</em>
The pieces are 3 ft, 28 ft, 9 ft, so total 40 ft, as required.
Step-by-step explanation:
(x+4)(2x−5)(x−1)
----------------------c
(x+1)(x+4)(2x−5)
(x+4)^(1-1)(2x-5)^(1-1)(2x-5)^(1-1)
(x+4)°(2x−5)°(x−1)°
1×1×1
1
law of indices says that x²/x=x^(2-1)=x
