An open rectangular box with square base has a volume of 256 cubic inches. determine the equation for the volume and surface are
Serjik [45]
Let
b-----------> the length side of the square box
h------------> the height of the box
SA---------> surface area of the box

we know that
[volume of the box]=b²*h
volume=256 in³
b²*h=256-------> h=256/b²-----> equation 1

surface area of the box=area of the base+perimeter of base*height

area of the base=b²
perimeter of the base=4*b

surface area=b²+(4*b)*h------> SA=b²+4*b*h-----> equation 2

substitute equation 1 in equation 2
SA=b²+4*b*[256/b²]-----> SA=b²+1024/b-----> SA=(b³+1024)/b

the answer is

the formula of the volume of the box is  V=b²*h-----> 256=b²*h

the formula of the surface area of the box are
SA=b²+4*b*h
SA=(b³+1024)/b

A line has a rise of 6 and a slope of 1/20 . What is the run?
Lerok [7]

Answer:

120

Step-by-step explanation:

\text{ Slope }=\frac{\text{ Rise }}{\text{ Run }}.

Plug in the information given:

\frac{1}{20}=\frac{6}{\text{ Run }}.

Now we want to solve this equation for Run.

If you don't like Run as a variable, let's just use x in it's place:

\frac{1}{20}=\frac{6}{x}

Cross multiply:

1(x)=20(6)

Simplify both sides:

x=120

The run is 120.

Let's check our work.

\text{ Slope }=\frac{\text{ Rise }}{\text{ Run }}.

So if our rise is 6 and our run is 120.

Does 6/120 reduce to 1/20?

6 and 120 do have a common factor of 6.

So if you divide top and bottom of 6/120 by 6 you do get 1/20.

Please help me and plz explain thoroughly i need help asap!
guajiro [1.7K]

f(x) = 2(x+8)

replace f(x) with 12 and then solve for x:

12 = 2(x +8)

Use the distributive Property on the right side:

12 = 2x +16

Subtract 16 from each side:

-4 - 2x

Divide both sides by 2:

x = -4 / 2

x = -2
