We have that 
Step-by-step explanation:
We have just to replace n=10 on the general equation
Therefore:
Answer:
960 ways
Step-by-step explanation:
Multiplication Principle: if there are n ways to do one thing and m ways to do another, then there are m x n ways to do both.
That can expand to include three things (or more).
8 x 10 x 12 = 960
In 2 hours they rest for 16 minutes.
So first we should work out how long they rested for in 1 hour.
We do this by simply doing 16 (minutes of rest) divided by 2 (hours of dancing):
16 / 2 = 8
In one hour of dancing they rest for 8 minutes.
Now to work out how long they rested in 3 hours, we simply do 3 (hours of dancing) x 8 (minutes of rest per hour):
3 x 8 = 24
The couple spent 24 minutes resting in 3 hours of dancing.
