How did you find how many gallons in a circular pool?
Several ways:# If the pool is full, you could empty it with a measuring container, preferably marked in gallons, and make a note of how many gallons you take out # If the pool is empty you could fill it with water, taking a note of how many gallons of water you put in. # You could use a 'pool capacity calculator' (Try a pool manufacturer's website). # You could calculate its capacity (Area of a circle times depth) This will give you its cubic capacity. Then find out the cubic size of a gallon. Then divide the pool's capacity by the cubic size of a gallon. The answer will be how many gallons.
Which of the following equations could you use to find the nth term of a compound interest sequence?

What multiplication fact could you use to find a number that can be divided evenly by 8 and 9?
The fact that 8 x 9 = 72
If you know that 7 times 8 equals 56how can you use communicative property of multiplication to find the product of 8 times 7?
You could use it because it shows that its just 7 times 8 flipped!
What could you use to find the nth term of a simple interest sequence?
All the terms are the same. If Y is the amount and r the percentage then the nth term is Y*r/100 for all n.
