The league championship 800 meter race has 6 runners.
s2008m [1.1K]

Answer: 120

Step-by-step explanation:

Given : The league championship 800 meter race has 6 runners.

The number of positions = 3

Since order matters here , so we use Permutation.

The permutation of n things taking r at a time is given by :-

^nP_r=\dfrac{n!}{(n-r)!}

Then, the number of different ways they place first, second, and third :_

^6P_3=\dfrac{6!}{(6-3)!}=\dfrac{6\times5\times4\times3!}{3!}=120

Hence, they can place first, second, and third in 120 different ways .

What is the area, in square units, of the polygon shown here?
WITCHER [35]
You just need to break it into parts. The first rectangle is the tall one. To find the area of this one, just multiply the tall side by the short side on top.

8 x 2 = 16

The second rectangle is the long one on the bottom. If the whole bottom side is 5 units, then you need to subtract 2 from that. 

3 x 1 = 3

16 + 3 = 19 units, so the area of the entire shape would be 19 units^2. Hope this helps! :)
