Answer:

<h2><u><em>9</em></u></h2>

Step-by-step explanation:

the mean is 6 (write on the picture)

so

(7 + 3 + 5 + x) : 4 = 6

(15 + x) : 4 = 6

15 + x = 24

x = 24 - 15

<u><em>x = 9</em></u>

<u><em>--------------------------------</em></u>

check

(7 + 3 + 5 + 9) : 4 = 6

24 : 4 = 6

6 = 6

the answer is good

Find the volume of the cube.
inna [77]

We will find the volume by multiplying length * width * height, like this:

10 cm * 3 cm * 2 cm = 60 cm^3

For ml, when we talk about volume, we know that the 1 ml = 1 cm^2, so the answer for ml is 60ml.

La suma de 5 números consecutivos es 122 cuáles son esos números ?​
ra1l [238]

Answer:

1) 22.4

2) 23.4

3) 24.4

4) 25.4

5) 26.4

Step-by-step explanation:

La suma de 5 números consecutivos es 122 ¿cuáles son esos números?

5 números consecutivos se pueden representar como

1) = x

2) x + 1

3) x + 2

4) x + 3

5) x + 4

Por eso:

x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 122

x + x + 1 + x + 2 + x + 3 + x + 4 = 122

5x +10 = 122

5x = 122 - 10

5 veces = 112

x = 112/5

x = 22.4

5 números consecutivos se pueden representar como

1) x = 22.4

2) x + 1 = 22.4 + 1 = 23.4

3) x + 2 = 22.4 + 2 = 24.4

4) x + 3 = 22.4 + 3 = 25.4

5) x + 4 = 22.4 + 4 = 26.4

If the cube above has a surface area of 54cm^3, what is the volume of the cube?
Colt1911 [192]

9514 1404 393

Answer:

  27 cm³

Step-by-step explanation:

The surface area of a cube is ...

  SA = 6s²

Then the edge length is ...

  54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area

  9 cm² = s² . . . . . .divide by 6

  3 cm = s . . . . . . . take the square root

The volume of a cube is ...

  V = s³

  V = (3 cm)³ = 27 cm³

The volume of the cube is 27 cm³.
