The following cube has a volume of 8000 cm3. Find the length of one side of the cube.

1 answer:

6 0

<span>Vcube = Ledge^3
8000cm^3 = Ledge^3

use the cube root of each side and you have the measure of an edge in cm.

8000^(1/3) = 20
every edge is 20 cm

20^2 = 400
The area of each face is 400 cm^2. </span>

A mole of 1 gallon cans of paint could cover every square inch of the surface of how many planets the size of the earth?

Nady [450]

Answer:

The answer is $4.4*10^1^0 planets$

Step-by-step explanation:

We ll have to find more information first to solve this question.

1. One mole = 6.022 x 10^23

Assuming one gallon of paint covers the 400 sq ft of area.

Thus total area which can be covered by 1 mole of gallon is

$=6.022*10^2^3 * 400\\=2.40*10^2^6$

2. Now we will find the surface area of earth

$Area = 4\pi R^2$

The radius of earth is 2.1 x 10^7 Feet

substituting values

$Area = 4*3.14*(2.1*10^7)^2\\Area = 5.5*10^1^5ft^2$

3. Now we will find out the number of planets of earth size which can be covered by mole of gallon of paint

= Total area one mole of gallon can cover / area of earth

$= 2.40 * 10^2^6/5.5*10^1^5\\=4.4*10^1^0 planets$

Which is larger 2/3" x 3-7/16" or 0.6"L x 3.43"W?

Darina [25.2K]

2/3 x (3 - 7/16) = (2/3) * (3+7/16)
= (2/3)*(55/16)
= 55/24
= 2.2917

0.6 x 3.43
= 2.058

The first answer is greater than the second.

Answer: 2/3 x 3-7/16 is larger.

What is the answer <br> y=2x+3<br> y=3x+5

Marizza181 [45]

We can use substitution.

We can substitute 2x + 3 for 'y' in the 2nd equation.

y = 3x + 5

2x + 3 = 3x + 5

Subtract 3 to both sides:

2x = 3x + 2

Subtract 3x to both sides:

-x = 2

Multiply -1 to both sides:

x = -2

Now we can plug this into any of the two equations to get our y-value:

y = 2x + 3

y = 2(-2) + 3

y = -4 + 3

y = -1

So our solution is (-2, -1)
