Answer: The maximum volume of the package is obtained with a cross section of side 18 inches and a length of 36 inches.

Step-by-step explanation: This is a optimization with restrictions problem.

The restriction is that the perimeter of the square cross section plus the length is equal to 108 inches (as we will maximize the volume, we wil use the maximum of length and cross section perimeter).

This restriction can be expressed as:

being x: the side of the square of the cross section and L: length of the package.

The volume, that we want to maximize, is:

If we express L in function of x using the restriction equation, we get:

We replace L in the volume formula and we get

To maximize the volume we derive and equal to 0

We can replace x to calculate L:

The maximum volume of the package is obtained with a cross section of side 18 inches and a length of 36 inches.

Answer: d=rt

Step-by-step explanation: the distance formula is speed times time. I’m guessing r=rate, and since speed and rate are similar I would say that’s the answer.

Step-by-step explanation:

I don't see the question

Answer: 50 miles

Step-by-step explanation:

600 / 15

= 40

It takes 40 minutes for the plane to go 600 miles

40 minutes is 40 / 60 hours which is 2 / 3

75 * (2 / 3)

= 50

The car travels 50 miles

2πr=circumference

Step-by-step explanation:

small circle has 12 inc length so it's circumference is 2*π*12 =24π

big circle has 14 İnc Length so it has 2*π*14=28

Answer:

Step-by-step explanation:

First find the airithmatic mean

(-3-5+8+11+13)/5= 4.8

[tex]\frac{(-3-4.8)^2+(-5-4.8)^2+(8-4.8)^2+(11-4.8)^2+(13-4.8)^2}{5}= 54.56[/tex]

The variance of this population data set is 69.45.

To find the variance of the set of data we first need to calculate the mean of the set.

mean = sum of each element / number of elements

mean = (-3 -5 + 8 + 11 + 13)/5 = 3.8

Now, using the formula for variance

s² = (X - mean)²/ (n- 1)

s² = (-3 - 3.8)² + (-5 - 3.8)² + (8 - 3.8)² + (11 - 3.8)² + (13 - 3.8)²   / (5- 1)

s² = 46.24 + 77.44 + 17.64 + 51.84 + 84.64 / 4

s² = 277.8/4

s² = 69.45

Hence, the variance of the data is 69.45.

The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities.

#3 is 1920 cubic inches

#4 i cant see the shape

Explanation:

the height is 1 inch so we can disregard that.

58 squared minus 38 squared is 1920 because if it was a square it would be side length 58 but we have to subtract 20 to find what is missing.

Step-by-step explanation:

Answer:

x = 27

Step-by-step explanation:

similar triangles

26/18 = 39/x

      x = 39(18/26)

      x = 27

could also use

39/x = (39 + 26) / (x + 18)

to get to the same result

39(x + 18) = x(39 + 26)

39x + 702 = 39x + 26x

         702 = 26x

              x = 27

or

18/x = 26/39

    x = 18(39/26)

    x = 27
