You are an engineer for a company that produces shipping boxes. The boxes that are made on one machine are all in the shape of a
Sidana [21]

Answer:

Step-by-step explanation:

Draw a picture of a cube and label the cube's side length, s. Prior to placing your order for more cardboard, tape, packing material, etc. your boss asked you to determine each of the following: a. Write an expression to determine the surface area of a cube-shaped box, SA, in terms of its side length, s (in inches).

The surface area of a cube of side length s is A = 6s^2; there are 6 sides each of area s^2.

If s is measured in inches, then A = 6x^2 inches^2.

b. Define a formula to determine the volume of a cube-shaped box, V, in terms of its side length, s, (in inches). Preview What are the units for the cube's volume?

The formula for the volume of a cube is V = s^3.  In this case, V is measured in inches^3.

c.  Given the formula for determining the volume of a 4 sphere is V = ar atrs, 3 (This is incorrect; the formula in question, for the volume of a sphere of radius r is V = (4/3)(pi)r^3.           (1) We can solve this formula for r^3, and then for r:

                                                  3V

3V = 4(pi)r^3 becomes r^3 = ------------

                                                 4(pi)

and so the formula for the radius of a sphere whose volume is 87 inches^3

is

     ∛(3V)        ∛3*87 in^3

r = ------------ = ------------------

      ∛(4pi)        ∛(4pi)

(2) The volume of the sphere when r = 5.9 in is:

                                                     4(3.14)      205.38 in³

(4/3)(pi)r^3 = (4/3)(pi)(5.9 in)³  =   --------- = --------------------- = 67.46 in³

                                                         3                 3

         

(3) V = (4/3)(pi)r³    

     Please share the possible answer choices.  Basically, you must find the volume twice:  once for a radius of 4 in and once for a radius of 2 in.  Then subtract the smaller from the larger.  The numerical result is the desired answer.

Determine the slope and y-intercept of the graph:<br> 7x + 4y = 28
barxatty [35]

Answer:

slope is  (-7/4) and y-intercept is 7

Step-by-step explanation:

If we convert the equation 7x + 4y = 28  into Slope-intercept form, we can find the slope and the y-intercept.

7x + 4y - 7x  =  28  - 7x

4y =  28 - 7x

divide both sides by 4

y = (28 - 7x)/4

y = 7 - 7x/4

slope is  (-7/4) and y-intercept is 7

6(3X +5 ) = 7(2x +2)
boyakko [2]

Answer:

X=-4 last answer i got i hope it is helpful have a nice day

Step-by-step explanation:

Let's solve your equation step-by-step.

6(3x+5)=7(2x+2)

Step 1: Simplify both sides of the equation.

6(3x+5)=7(2x+2)

(6)(3x)+(6)(5)=(7)(2x)+(7)(2)(Distribute)

18x+30=14x+14

Step 2: Subtract 14x from both sides.

18x+30−14x=14x+14−14x

4x+30=14

Step 3: Subtract 30 from both sides.

4x+30−30=14−30

4x=−16

Step 4: Divide both sides by 4.

4x

4

=

−16

4

x=−4

Answer:

x=−4
