The volume of a cylinder is 88 cubic inches. A smaller container, similar in shape, has a scale factor of 1/2. What is the volume of the smaller container? If someone could not only give me the answer, but also explain to me HOW they did the problem, that would be great!

I have many ugly formulas that I have to add 2 to 8 times with a different value of x.
example (x^2)/4 + 456x^3 + (523/17)x^2 + 3x =932.1

I tried entering this:
(x^2)/4 + 456x^3 + (523/17)x^2 + 3x =932.1, x=4
(x^2)/4 + 456x^3 + (523/17)x^2 + 3x =932.1 x=7
(x^2)/4 + 456x^3 + (523/17)x^2 + 3x =932.1 x=9
etc.
etc.
but I get syntax errors

How do I do this with the ti-89 please?

I heard this riddle from my teacher but i couldnt figure it out can any of you.


March 14 is Pi DAy(3/14) if we live in a base ten world and March 14 is pi day what would pi day be if we lived in a base eight world.

I know very hard keep in mind that the numbers go from 0-7 in a base eight world not 1-8. And in a base ten world it is 0-9 not 1-10. If u figure it out plse explain

I know that if the class has two outer limits, e.g. !-3 then you just add the two limits and divide by 2, but if you have one without and upper limit, e.g. 60+ how would you work out the mid point?
