8•20=q. Multiply the number of piles by the number of quarters in each pile: 8•20=160, there were 160 quarters. Now to find how much they made multiply the number of quarters by how much 1 quarter is: 160•.25=40 they made $40 :)
Answer:
The answer is...
Step-by-step explanation:
Each interior angle measures 108 degrees. All of the angles are congruent. The sum of the measures of the interior angles is 108(5-2) degrees.
Formula for combinations:
(n!)/(r!(n-r)!)
For you, this is:
10!/(5!(10-5)!) = 10!/5!5! = (10•9•8•7•6•5•4•3•2)/(5•4•3•2)(5•4•3•2) = (10•9•8•7•6)/(5•4•3•2) = 30240/120=252 different ways.
