Answer:
Step-by-step explanation:
8 filters = $39.92
1 filter = 39.92 : 8 = $4.99
6 filters = 6 × 4.99 = $29.94
Let x =lenght, y = width, and z =height
<span>The volume of the box is equal to V = xyz </span>
<span>Subject to the surface area </span>
<span>S = 2xy + 2xz + 2yz = 64 </span>
<span>= 2(xy + xz + yz) </span>
<span>= 2[xy + x(64/xy) + y(64/xy)] </span>
<span>S(x,y)= 2(xy + 64/y + 64/x) </span>
<span>Then </span>
<span>Mx(x, y) = y = 64/x^2 </span>
<span>My(x, y) = x = 64/y^2 </span>
<span>y^2 = 64/x </span>
<span>(64/x^2)^2 = 64 </span>
<span>4096/x^4 = 64/x </span>
<span>x^3 = 4096/64 </span>
<span>x^3 = 64 </span>
<span>x = 4 </span>
<span>y = 64/x^2 </span>
<span>y = 4 </span>
<span>z= 64/yx </span>
<span>z= 64/16 </span>
<span>z = 4 </span>
<span>Therefor the dimensions are cube 4.</span>
First do 8-3 and get 5
(5)!....
This means 5 x 4 x 3 x 2 x 1
= 120
Answer:
1/2 = 4/8
Step-by-step explanation:
An equivalent expression is when two fractions, decimals, or percents both match up because they are the same quantity as the other number.
The fractions above are an example of 1/2 and 4/8, which are equal to each others. The equation above is an example of an equivalent expression.
