Contact [7]

Answer:

<em>We</em><em> </em><em>can</em><em> </em><em>say</em><em> </em><em>that</em>

<em> </em>3x + x + 8 = 32

<em>So</em><em>:</em><em> </em>

3x + x + 8 = 32

4x = 32 - 8

4x = 24

x = 24/4

A park has 22 elm trees. Elm leaf beetles have been attacking the trees. After removing several of the diseased trees, there are
serg [7]

Answer: 9 elm trees were removed.

Step-by-step explanation:

Let x represent the number of elm trees removed.

The total number of elm trees in the park is 22. Elm leaf beetles have been attacking the trees. After removing several of the diseased trees, there are 13 healthy elm trees left. The equation to find the number of elm trees that were removed would be

x + 13 = 22

Subtracting 13 from the left hand side and the right hand side of the equation, it becomes

x + 13 - 13 = 22 - 13

x = 9

A rectangular tank that is 2048 ft cubed with a square base and open top is to be constructed of sheet steel of a given thicknes
ira [324]

Answer:

The box should have base 16ft by 16ft and height 8ft Therefore,dimensions are 16 ft by 16 ft by 8 ft

Step-by-step explanation:

We were given the volume of the tank as, 2048 cubic feet.

Form minimum weight, the surface area must be minimum.

Let the height be h and the lengths be x

the volume will be: V=x²h then substitute the value of volume, we have

2048=hx²

hence

h=2048/x²

Since the amount of material used is directly proportional to the surface area, then the material needs to be minimized by minimizing the surface area.

The surface area of the box described is

A=x²+4xh

Then substitute h into the Area equation we have

A= x² + 4x(2048/x²)

A= x² + 8192/x

We want to minimize

A

dA/dx = -8192/x² + 2 x= 0 for max or min

when dA/dx=0

dA/dx= 2x-8192/x²=0

2x=8192/x²

Hence

2x³=8192

x³=4096

x=₃√(4096)

X=16ft

Then h=2048/x²

h=2048/16²

h=8ft

The box should have base 16ft by 16ft and height 8ft

Hence the dimensions are 16 ft by 16 ft by 8 ft
