So first step is to simplify everything outside of the radicals.
6*2=12
:. The expression is
__ __
12*\| 8 * \| 2
Now we know that
__ __ __
\| 8 = \| 4 * \| 2

And
__ __
\| 2 * \| 2 = 2

And
__
\| 4 = 2

So if we incorporate what we know into the equation, we can figure it out.
So let's first expand the radical 8.
__ __ __
12*\| 4 * \| 2 * \| 2

Now by simplifying the radical four and combining the radical twos, we can get all whole numbers.
12*2*2
Which equals 48.

Find the mean and range.<br><br> 26 19 23 39 31 34 23 25
sveticcg [70]
Range: largest number minus the smallest number
39 - 19 = 20
your range is 20

Mean: add all of the numbers and divide by the amount of numbers there are.

26+19+23+39+31+34+23+25= 220
220/8 = 27.5

your mean is 27.5

hope this helps

What is the surface area of a cone that has a radius of 8 feet and a slant height of 12 feet? (Use 3.14 for π.)
kodGreya [7K]

Answer:

Surface area of cone is 502.4\ ft^2

Step-by-step explanation:

Given:

radius of a cone (r) = 8 feet

slant height of cone (l) = 12 feet

We need to find the surface area of cone.

Total surface area of cone = Area of circle + Area of curved surface

Now we know that,

Area of circle = \pi r^2

Area of curved surface = \pi rl

Hence Total surface area of cone = \pi r^2+\pi rl=\pi r(r+l) = 3.14 \times 8 (8+12)=3.14\times8\times20= 502.4 \ ft^2

Surface area of cone is 502.4\ ft^2.

What is the sum of 1 2/5 and 5 3/4​
Art [367]

Answer:

7\frac{3}{20}

Step-by-step explanation:

<em>Hey there!</em>

Well to add this we need to pu it in improper form.

7/5 + 23/4

Now we need to find the LCM.

5 - 5, 10, 15, 20, 25, 30

4 - 4, 8, 12, 16, 20, 24, 28

So the LCD is 20.

Now we need to change the 5 and 4 to 20.

5*4 = 20

7*4 = 28

<u>28/20</u>

4*5=20

23*5=115

<u>115/20</u>

Now we can add 28 and 115,

= 143/20

Simplified

7 3/20

<em>Hope this helps :)</em>
