Solution : Given points to be fill are : 5 external points + 5 internal points

Total positions to be fill are 5+5 = 10

given number of sea shell to be placed are = 10

Here all sea shell are different so each sea shell is different from any other sea shell

if we interchange the position of any two sea shell we would be getting totally different

arrangement .

We can think this problem like 10 sea shell are to be placed at 10 different places

We start with placing first sea shell .

In the beginning we have 10 positions

once it is placed we pick second sea shell and now we have only 9 vacant places

once it is placed we pick next ses shell and we have 8 vacant places for it

we continue with it till we place the last sea shell for which we would be having

only 1 vacant place.

This way the total number of arrangements we get : 10x9x8x7x6x5x4x3x2x1 = 3628800

ANSWER = 3628800

yulyashka [42]
Surface area of a square pyramid is the area of the base + 4 times the area of one of the slanted sides.
Area of base = side length * side length
Area of side = (1/2) * side length * slant height
Don't forget that you have to multiply the area of the side by 4!

Step 1: 12 x 12 = 144
Step 2: 12 x 20 = 240 divided by 2 = 120
Step 3: 144 + 120 x 4

A car with a cost price of $5200 is<br> sold at a profit of 15%. Calculate the<br> selling price
andriy [413]

Answer:

We are given the initial price of a car and we are also told that the car sold for a 15% profit which means that the price that the car was sold for is 15% more than it's initial price.  This is just a simple multiplication problem which we multiply the initial price by the total percentage plus 0.15

Sold\ Price = Initial\ Price *(Total\ Percentage+Profit\ Percentage)

Sold\ Price = \$5200*(1+0.15)

Sold\ Price = \$5200*(1.15)

Sold\ Price = \$5980

Therefore, our final answer is that the selling price was $5980
