How many solutions 4(x-5)=3x+7

ohaa [14]

$4(x-5)=3x+7 \\ \\ 4x - 20 = 3x + 7 \\ \\ 4x = 3x + 7 + 20 \\ \\ 4x = 3x + 27 \\ \\ 4x - 3x = 27 \\ \\ x = 27 \\ \\$

The final result is: x = 27

A pyramid has a square base that is 160m on each side. What is the perimeter of the base in kilometers?

Nikolay [14]

The perimeter is the sum of all sides' lengths

So the perimeter = 4*160 m =640 m = 0.64 km

How can you find all of <br> the dimensions of a rectangle prism with the given volume

katen-ka-za [31]

You can't. Knowing the volume doesn't tell you the dimensions.
There are an infinite number of different rectangular prisms, all
with different dimensions, that all have the same volume.

Here's an example. Let's say I have a rectangular prism and its
volume is 64.

The dimensions could be . . .

1 x 1 x 64
1 x 2 x 32
1 x 4 x 16
1 x 8 x 8
2 x 2 x 16
2 x 4 x 8
4 x 4 x 4 .

If I only tell you the volume, there is no way to figure out the dimensions.

Trey had a cylindrical can with a radius of 4 inches and a height of 12 inches that was completely full of beet juice. He poured

Slav-nsk [51]

Answer:

$8\ glasses\ of\ juice$

Step-by-step explanation:

step 1

Find the volume of the cylindrical can

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=4\ in$

$h=12\ in$

substitute the values

$V=\pi (4)^{2}(12)=192\pi\ in^{3}$

step 2

Find the volume of the cylindrical glasses

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=2\ in$

$h=8\ in$

substitute the values

$V=\pi (2)^{2}(8)=32\pi\ in^{3}$

<em>Find the volume of 3/4 of the glass</em>

$32\pi (\frac{3}{4})=24\pi\ in^{3}$

step 3

Divide the total volume of cylindrical can by the 3/4 volume of the glass

$192\pi\ in^{3}/24\pi\ in^{3}=8\ glasses\ of\ juice$
