thanks XSquared :)

Yes you are right 

I assume he means our web2 calc :)

You have to do it the old fashion way.

\(4\frac{1}{4}-2\frac{7}{9}\)

(4+1/4)-(2+7/8)=

(4+1/4)-(2+7/8) = 1.375  The calc actually did show the improper fraction answer as well.

But if you need a fraction calculator I suggest you do not use this one.

Thanks asinus :)

Guest:

Are you supposed to use physics formulas or calculus ?

Do you understand asinus's answer and is that what you were after ?

rating of 42/9 

5,5,5,5,5,5,5,5,2  would be one possibility

or

5,5,5,5,5,5,5,4,3

or

lots of other combinations :)

The 9 numbers must add to 42

If it is EXACTLY 4.44 then that is     4 and 11/25

So it would be a minimum of 25 responses.

In a 5 star rating, how can i achieve a rating of 4.44 in the least amount of responses? The responses can only be 1, 2, 3, 4, or 5.

4.44 .... I thought it was repeater :(

If it was repeater, and yes I know it is not,  then the rating wouldbe 42/9  so you would need a multiple of 9 responses. 

The minimum would be 9

what is -2 to the 5th power

\((-2)^5=-32\\ and\\ -2^5=-1*2^5=-32\)

What would be the answer to 6 over the square root of 5 minus the square root of 2?

I think you mean the simplification rather than the answer:)

\(\frac{6}{\sqrt5}-\sqrt 2\\ =\frac{6}{\sqrt5}*\frac{\sqrt5}{\sqrt5}-\sqrt 2\\ =\frac{6\sqrt5}{5}-\frac{5\sqrt 2}{5}\\ =\frac{6\sqrt5-5\sqrt 2}{5}\\\)

OR maybe you meant:

\(\frac{6}{\sqrt5-\sqrt2}\\ =\frac{6}{\sqrt5-\sqrt2}\times \frac{\sqrt5+\sqrt2}{\sqrt5+\sqrt2}\\ =\frac{6(\sqrt5+\sqrt2)}{(\sqrt5-\sqrt2)(\sqrt5+\sqrt2)}\\ =\frac{6(\sqrt5+\sqrt2)}{5-2}\\ =2(\sqrt5+\sqrt2)\\\)

I repeat:

Do you mean that the volume is   0.5cm^3 or do you mean that the side length of the cube is 0.5cm?

THEY ARE DIFFERENT!

BUT GUEST ANSWER  #3   IS CORRECT.

Thanks #3  :)
