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

The Stonyfield Smoothies have 150 mg of Sodium. When I tried one yesterday it kindda tasted salty and I was wondering is that a lot for this type of drink? By the way, it was Blueberry flavor, if that makes a difference.

Interestingly enough soda has like 30-50 mg of sodium.

QUESTION: Is 150 mg of sodium a lot for a smoothie?

I'm watching this movie one the Sci-fi Channel, Tidal Wave-No Escape, and each tidal wave comes in with no warning at all. It doesn't seem realistic. Can they do that, come in without warning?
