we know that
A <u>geometric sequence</u> is a sequence of numbers in which the ratio between consecutive terms is constant
so
Let







therefore
The common ratio is equal to 
<u>the answer is</u>
The common ratio is 1.02
If he gives ALL of the cookies away..
3 5/6 = 6/6 + 6/6 + 6/6 + 5/6
6+6+6+5 = 23
Paul has 23 friends. (if he takes 1/6, then he has 22)
hope this helps
The area formula for a parallelogram is base*height=area. Make an equation. You know the area and the height, so plug that into the equation, and you get x*18=396. Solve for x by dividing 396 by 18 and you get 22. So, the base is 22cm.
