What is 4^{3 ?}

Well if you know that 4²  is 16

(4x4)

So to get the 3rd power, you take 16 and multiply by 4

4³ IS THE SAME AS 4x4x4 !

4x4=16 x 4 = 64

I did NOT include the negative signs

Also others may have a better way but i would just start from a number like 4, and multiply it 3 times, and see how close to 64 i am.

It sounds like they both at one time had books, but had is past-tense...meaning they dont have any books anymore.

Answer= 0

tan 28.2 = 1640x 
=> 0.5361 = 1640x 
=> 0.5361x = 1640
=> x = 1640 \  .5361
=> x = 3059 m

Did i completley fail or something? But thats what I got.

Tan28.2(the degrees) is = or aka .5361 when calculated(for me anyway)

So just dividing the height of the blimp which is 1640, by the tan28.2(in decimal)(.5361)

should be the answer? no?

I guess I wasn't clear enough :P  Let me rephrase!

"   85.6 + 78.5 + 92.5 + 67 + 83.7  =ANSWER  then DIVIDE by 5  :)   "

85.6 + 78.5 + 92.5 + 67 + 83.7 = 407.3

407.3 DIVIDED BY 5 = 81.46

To EASILLY get the average of ANYTHING EVER!!!

You simply do this...

You have there 5 numbers, yes?

Add those 5 numbers all up, and then divide by 5, since that is how many numbers there are in total.

85.6 + 78.5 + 92.5 + 67 + 83.7  =ANSWER  then DIVIDE by 5  :)

EXAMPLE QUESTION:

What is the average of 11.4, 55.5, 34.2, 18.2, and 42 ?

Well add all those up and you get..  161.3

ALWAYS add up the numbers, then divide by how many numbers there were.

So now i do 161.3 DIVIDED BY 5 = 32.26
