1. We assume, that the number 128 is 100% - because it's the output value of the task. 
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 128 is 100%, so we can write it down as 128=100%. </span>
<span>4. We know, that x is 51% of the output value, so we can write it down as x=51%. </span>
5. Now we have two simple equations:
1) 128=100%
2) x=51%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
128/x=100%/51%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 51% of 128

128/x=100/51
<span>(128/x)*x=(100/51)*x       - </span>we multiply both sides of the equation by x
<span>128=1.96078431373*x       - </span>we divide both sides of the equation by (1.96078431373) to get x
<span>128/1.96078431373=x </span>
<span>65.28=x </span>
x=65.28

<span>now we have: </span>
<span>51% of 128=65.28</span>

A cylinder has diameter 34 m and height 27 m. A label at bottom states drawing not to scale.
Blababa [14]

Answer:

Therefore,

Volume of the cylinder is 24501.42 m³.

Step-by-step explanation:

Given:

Height of Cylinder = 27 m

Diameter, d = 34 m

Radius = \dfrac{d}{2}=\dfrac{34}{2}=17\ m

Volume of a Cylinder = ?

Solution:

We know that

\textrm{Volume of a Cylinder}=\pi (Radius)^{2}\times Height

Substituting the given values in formula we get

\textrm{Volume of a Cylinder}=3.14 (17)^{2}\times 27=24501.42\ m^{3}

Therefore,

Volume of the cylinder is 24501.42 m³.

2.4z + 1.2z -6.5 = 0.7<br> Solve for z
eduard
2.4z + 1.2z = (2.4 + 1.2)z = 3.6z;
We have 3.6z - 6.5 =0.7   / +6.5;
3.6z = 7.2   / ×10;
36z = 72   / ÷36;
z = 2.
