I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7

II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)

What is the volume of a cylinder with a radius of 10 meters and a height of 4 meters?
Licemer1 [7]

Answer:

The volume of the cylinder is about 1256.6 cubic meters.

Step-by-step explanation:

The volume of a cylinder is given by the formula:

\displaystyle V=\pi r^2h

Where <em>r</em> is the radius and <em>h</em> is the height.

Our radius is 10 meters and our height is four meters. Substitute:

\displaystyle V=\pi(10)^2(4)

Evaluate:

V=400\pi \text{ m}^3\approx 1256.6\text{ m}^3

Thus, the volume of the cylinder is about 1256.6 cubic meters.
