Answer:
120 ways
Step-by-step explanation:
Since no girl wil sit either first or last
Hence, in all irrespective whether boy or girl = (6 - 1)! = 5! = 5 X 4 X 3 X 2 = 120

Answer:
n = 18
Step-by-step explanation:
The formula for angle sum of a polygon is S = 180 (n - 2), where S is the sum and n is the sides.
We are given that the sum is 2880, and are trying to find n.
Simply sub in S = 2880,
2880 = 180 (n - 2)
Divide by 180 to get (n - 2) by themselves on the right side,
16 = n - 2
Now add 2 to the other side to get n by itself
18 = n
n = 18
Hope this helped!! Please feel free to ask me if there's anything you don't understand from this working
It depends on how fast it was thrown/kicked but the average is around 9/10
