Step-by-step explanation:
X + 9= 7
 get x by itself you -9 on both sides
X + 9 = 7
 - 9. -9
X = -2

Answer:
x=104
Step-by-step explanation:
Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)
10.5 = 1/2( x-83)
Multiply each side by 2
2* 10.5 = 2*1/2( x-83)
21 = x-83
Add 83 to each side
21+83 = x-83+83
104 =x
 
        
                    
             
        
        
        
Answer:
3.5%
Step-by-step explanation:
The volume of a cylinder = 
<em>r</em> = radius of cylinder,
<em>h</em> = height of cylinder
For the non-optimal can,
<em>r</em> = 2.75/2 = 1.375
<em>h</em> = 5.0

<em />
For the optimal can,
<em>d</em>/<em>h</em> = 1,
<em>d</em> = <em>h</em>
2<em>r </em>=<em> h</em>
<em>r</em> = h/2

They have the same volume.
<em /> <em />
<em />

 (This is the height of the optimal can)
 (This is the height of the optimal can)
 (This is the radius of the optimal can)
 (This is the radius of the optimal can)
The area of a cylinder is
<em /> <em />
<em />
For the non-optimal can,

For the optimal can,

Amount of aluminum saved, as a percentage of the amount used to make the optimal cans =
