Some other dumb problems

2010 A:

#64: In how many ways can Larry, Mo, and Curly sit in a row of five chairs?

Why is this permutations instead of combinations?

#65 The greatest integer function [unparseable or potentially dangerous latex formula] has a value of ______________________ for [unparseable or potentially dangerous latex formula]

I know what this wants but what do you do for greatest integer functions for negative values? I put [unparseable or potentially dangerous latex formula] for this one...

Also from 2010 A:

#72 [unparseable or potentially dangerous latex formula]

Also is the area of an ellipse [unparseable or potentially dangerous latex formula] [unparseable or potentially dangerous latex formula] for ellipse equation [unparseable or potentially dangerous latex formula] like [unparseable or potentially dangerous latex formula] being a value...

Conversions:

mph to ft/s vice versa

sam 4 ft/min...

I got this approx once like the ft/min. and i didn't want to waste my time...

I know how to figure this stuff out but u know - getting info is better than using the time to find it (showing laziness :P)

Miles per hour to feet per second: Multiply by 22/15, and vice versa, multiply by 15/22.

You guys know - i hope - that i am not those 80s guys in NS...
Therefore, I wante to find out why i am not one among those...
Well the natural ans would be - well i am not that smart.
But apart from that, there are a few other dumb questions that block my way!

For example, the remainder question.
I mean i know the trick, i know how to do it, and i can do it if you give me a minute - not just 10 seconds!

Well I mean the remainder problems that look something like this:

[unparseable or potentially dangerous latex formula] has a remainder of _______________________

or

[unparseable or potentially dangerous latex formula] has a remainder of ______________________

When I had come across this fact, naturally, I had begun to skip these kind of questions...
This is when I got to the high 60s (after skipping a few more of the time consuming ones...)

How do you do this in less than 10 seconds (with being as smart as I am - not too too smart you know)?

I mean this can get me like 9 more pts which could help me with higher scores!

Also another question:

2012A:

The polar coordinates of the rectangular coordinates [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula]. The smallest positive value of [unparseable or potentially dangerous latex formula] is ___________________ .

I ment 8, sheesh... I'm having a bad day okay...


Edit: Fixed it. I apperently was thinking 3 plus 3 instead of 3 times 3. But whatever, you get the point. Heh, sorry about that.
