Last week John made/has $50.00 from playing the lottery. This week he lost $25.00 playing the same lottery game. What is his per
cent of change between last week 20. and this week? First find the difference, the amount of change in John's money, then find the percent of change for how much money John now has.
Okay, so we already have the volume equation for a cylinder here. Since we need to find the height(h), we need to basically isolate it in the equation. To do that we just have to divide both sides by (pi * r^2), where we end up with: then
"Anything equals itself: this is the "reflexive" (reflecting onto itself) property. Also, it doesn't matter which order the equality is in; if x = y, then y = x: this is the "symmetric" (they match) property."
