A = LW
A = 2/3 * 3/4
A = 6/12 = 1/2 miles^2
Answer:
d = √5 ≈ 2.24
Step-by-step explanation:
B is located at (1, 3) and B' is located at (3, 4)
Distance formula:
[tex] d = \sqrt{(xB' - xB)^2 + (yB' - yB)^2}[\tex]
replacing with the coordinates of the points:
[tex] d = \sqrt{(3 - 1)^2 + (4 - 3)^2}[\tex]
[tex] d = \sqrt{4 + 1}[\tex]
d = √5 ≈ 2.24

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 />

(This is the height of the optimal can)
(This is the radius of the optimal can)
The area of a cylinder is
<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 =
