Answer:

21

Step-by-step explanation:

n, n + 2, n+3, n+5, n+7, n+8, n+11, n+14, n+16, n+19

The median is the middle number

There are 10 numbers so the middle is between the 5th and 6th number

n, n + 2, n+3, n+5, n+7,       n+8, n+11, n+14, n+16, n+19

We average those two numbers

(n+7  + n+8)/2 = 20

(2n+15)  / 2 = 20

Multiply by 2

2n+15 = 40

Subtract 15

2n = 25

Divide by 2

n = 25/2

n = 12.5

We want to find the mean, which is add up all the numbers and divide by the number of numbers

(n+ n + 2+ n+3+ n+5+ n+7+ n+8+ n+11+ n+14+ n+16+ n+19)/10

(10n+85)/ 10

n+ 8.5

12.5 + 8.5 = 21

The formula for volume always involves three dimensions.  

In this case, the volume of a cube is V=s^3, where s is the side length of the cube.

To solve for that side length, you'd need to use a cube root.

Can I get help on this please
Alekssandra [29.7K]
Hello!

I've attached the diagram.

For this problem, since you have a right triangle, you can use the Pythagorean Theorem to fine the length of the ladder (the hypotenuse of the triangle).

Pythagorean Theorem (where c is the hypotenuse):
a² + b² = c²

The triangle's leg lengths are 8 and 6; substitute into the theorem:
8² + 6² = c²

Simplify:
64 + 36 = c²
100 = c²
10 = c

Answer:
The length of the ladder is 10 m.

Answer:

see below

Step-by-step explanation:

m/3 + 4 = 7

Subtract 4 from each side

m/3+4-4 = 7-4

m/3 = 3

Multiply each side by 3

m/3*3 = 3*3

m =9

sammy [17]
Average of 5 games = 13
Total of 5 games = 13 x 5 = 65

Average of 6 games = 17
Total of 6 games = 102

6th game = 102 - 65 = 37
