i think…

and, just so you know…I did these while procrastinating from studying for my calc test tomorrow…

#3 is right, but #1 and #2 are not. guess you have some more procrastination ahead of you… (=

hmmmm….well, procrastination is no longer needed…but fun is!

1) 2.414 I am not sure WHAT I was thinking the first time…I did some very dumb things….oh, silly me!

2) 1.333…

OK, you got #1 now. sorry to hear about the dumb things. (= #2 is still not right. How are you trying to solve it?

Is #2 1.264?

yes, that’s right. Now, to a real mathematician, none of these answers would be technically correct since they are all

approximations(the answer to #2 is notexactly1.264, and so on). Does anyone know the exact answers (in terms of square roots and so on)?Ohh…this is fun. I guess it would be (3+√(21))/6?

you got it. Glad it is fun!

brentos… hallo! i must confess i didnt try any of the math problems, but i just want to say hi to you and to mrs. joyia yorgey as well… hehe that still feels weird to say!
