Metal Fabrication If an open box is made from a tin sheet 10 in. square by cutting out identical squares from each corner and be
MrRa [10]

Answer:

  • ength (l) : (10-2*5/3) = 20/3
  • width(w): (10 - 2*5/3) = 20/3
  • height(h): 5/3

Step-by-step explanation:

Let x is the side of identical squares

By cutting out identical squares from each corner and bending up the resulting flaps, the dimension are:

  • length (l) : (10-2x)
  • width(w): (10-2x)
  • height(h): x

The volume will be:

V = (10-2x) (10-2x) x

<=> V = (10x-2x^{2}) (10-2x)

<=> V = 100x -20x^{2} - 20x^{2} + 4x^{3}

<=> V = 4x^{3}  - 40x^{2} + 100x

To determine the dimensions of the largest box that can be made, we need to use the derivative and and set it to zero for the maximum volume

dV/dx = 12x^{2} -80x + 100

<=>  12x^{2} -80x + 100 =0

<=> x = 5 or x= 5/3  

You know 'x' cannot be 5 , because if  we cut 5 inch squares out of the original square, the length and the width will be 0. So we take x = 5/3

=>

  • length (l) : (10-2*5/3) = 20/3
  • width(w): (10 - 2*5/3) = 20/3
  • height(h): 5/3

Please answer the question in the picture below. Thanks!
Arada [10]

Answer:

Yes

Step-by-step explanation:

\frac{DH}{HE}=\frac{18}{36}=\frac{1}{2}

\text{This means that } DH=\frac{1}{2}HE

and thus the given segments are parallel by the converse of the triangle proportionality theorem.

Solve the equation for me<br> 9y=8(y+11)
IrinaVladis [17]
To start, first distribute 8 to (y+11) which would look something like this:
9y=8y+88
Now, subtract 8y from both sides in order to solve for and isolate the y value. This would result in your answer, y=88.

What is the probability that you will select someone from the survey that does not watch NBC? Explain.
maria [59]

Answer:

It is the last choice, 53.33%.

Step-by-step explanation:

The number who don't watch NBC is 20+4 = 24.

So the fraction who do not watch NBC  = 24/45

= 53.33%
