A cardboard box without a lid is to have a volume of 8,788 cm3. Find the dimensions that minimize the amount of cardboard used.

Montano1993 [528]

Answer:

x = y = 26 cm; z = 13 cm

Step-by-step explanation:

The generic solution for the minimum material in an open-top box is that the box is square and half as high as it is wide. It is half a cube of twice the volume.

The dimensions of the square base are ...

∛(2·8788 cm³) = 26 cm

Then the height is half that, or 13 cm.

x = y = 26 cm; z = 13 cm

_____

If you need to see the development, you can use the method of Lagrange multipliers to find the minimum area for the given volume;

area = xy +2(xz +yz)

volume = xyz = 8788

We require each of the partial derivatives of L with respect to x, y, z, and λ to be zero.

L = xy +2(xz +yz) +λ(xyz -8788)

partial with respect to x: 0 = y+2z +λyz

partial with respect to y: 0 = x +2z +λxz

partial with respect to z: 0 = 2x+2y +λxy

partial with respect to λ: 0 = xyz -8788

From the first two equations, we have ...

λ = (y +2z)/(yz) = 1/z +2/y

λ = (x +2z)/(xz) = 1/z +2/x

Equating these expressions for λ, we find ...

1/z +2/y = 1/z +2/x ⇒ x = y

The third equation then tells us ...

λ = (2x +2y)/(xy) = 2/y +2/x

Comparing this to either of the first two expressions for λ, we see ...

1/z +2y = 2/x +2/y ⇒ z = x/2

This is the result we started the answer with:

x = y = 2z = ∛(2·8788 cm³)

Major league baseball team plays 162 game schedule so far graces favorite team won 11 games and lost 7 games if graces team wins

Vinil7 [7]

Answer:

Graces expect her Favorite team can win 99 games.

Step-by-step explanation:

Total games needs to be played = 162

So far graces favorite team won 11 games and lost 7 games

Games Won = 11

Games lost = 7

Total games played till now = Games Won + Games Lost = 11 +7 =18

Now we will find the winning percentage of the team.

Winning percentage can be calculated by dividing Games won with total games played till now and the multiplied with 100

Winning Percentage = $\frac{11}{18}\times100=61.11\%$

We need to find Total games team can win at same rate.

Games team can win can be calculated by multiplying Total games needs to be played this season with Winning Percentage.

Games team can win = $\frac{61.11}{100}\times 162 = 98.99 \approx 99$

Hence Graces can expect her favorite can win approximately 99 games.
