√3/2tan30-√3sin60-√2cos45 =

[√3 / 2] [1  / √3] - √3] [√3 / 2 ] - √2 [ 1 / √2]  =

1/2  -  3/2  - 1  =

-1  - 1  =

-2

If the first farmer only sells his eggs....he makes $1.50   = .5 cent = 1/2  cent for each egg

If the second farmer sells only his eggs.....he makes $1.00 =  1/3 cent for each egg

So the total made is  300 * (1/2) cents + 300 * (1/3)cents  =  [150 + 100 ]  cents = 250 cents = $2.50

However....if they combine their products......they sell  600 eggs at  2/5 cents each  = 600 * (2/5) cents  = 240 cents = $2.40

To make the same profit by combining eggs........each egg should have been sold   at  [ 1/2 + 1/3 ] / 2  =  5/12 cents

Proof :   600 * 5/12 =  50 * 5   = 250 cents  = $2.50

41/8 or 5 1/8

just use the division bar that's what works best.

Yah.....it is a pain.    Hope they ' fix ' it ...you have my vote!

Thanks EP: I think it would make much more sense, since in the course of 1 day, about 100 questions are asked on this site. Besides, when click on the bottom of the page, your cursor shoots automatically to the top of the page. And then you have to scroll down to where you were only seconds earlier.

OK...you should ask that the DEFAULT value of 25 be changed to a default of 100 for ALL users.....Good luck....sounds like a good idea to me!

I know that, but lots of young people don't seem to know that!.

People are trying to be funny because I know they know the answer...

YOU can select how many questions to be displayed at the bottom of the list....look at the lower right at the bottom.

ok i found my mistake .. thank you!!

This question has been posted and answered on here about a 'buh-jillion' times.   Not sure why...it is kind of stupid.....Maybe YOU think it is funny, I guess....

Anyway: What do YOU think the answer is????

19..

i want to factorize this : (a-3b)(x+y)-(x-y)(3b-a) so my solution is (a-3b)(x+y)(x-y)

but the book gives this solution : 2x(a-3b)

is it a misprint or i am wrong?

LOTS and lots of choices here

how about     3 x 4 x5 

Maximum's the largest

Minimum's the smallest

Mode is the one you see the most

Median's the number you see in the middle

Range is the maximum subtract the minimum

And mean is all the numbers added up, then divided by the amount of numbers there are.

Pick one

APR = 12%

compounded quarterly (every three months)    Periodic interest =  12/4 = 3% = .03 = i

APY = (1+i)^n       where n=periods in a year (4)

APY = 1- (1.03)^4 = .1255    =  12.55 Percent

Which shows that compounding will effectively raise the APR     MORE frequent compounding will raise it even more!  

then i'd suppose you would be nameless??

OK, kiddo!.

Will use 10%.

APR          PERIODS OF COMPOUNDING            APY

10%                              1 per year                             10%

                                      2 ,,,,,,,,,,,,                             10.25%

                                      4,,,,,,,,,,,,,                              10.38%

                                      6,,,,,,,,,,,,,                               10.43%

                                     12,,,,,,,,,,,,                                10.47%

                                      26,,,,,,,,,,,                                10.50%

                                      52,,,,,,,,,,,                                 10.51%

                                      365,,,,,,,,,                                  10.52%

                                      Continuously                            10.52%

I HOPE YOU ARE HAPPY!!                           

It doesn't:

(x-y)(x+y)       Use distributive property

x^2 + xy  - xy - y^2

=x^2 - y^2

3 / 4  = 0.75   ....so.....

0.75 * 37.5   = 

28.125

-3 / -4   =      [ -1 * 3 ] / [ -1 * 4 ]  =   3 / 4

40,000 mph =64,373.76 km/h

Distance to Pluto =~7.5 x 10^9 km.

[7.5 x 10^9] / 64,373.76 =~116,507 hours /24 hours =~4,854 days/365.25 days =~13 years.

But only if the two planets were stationary. However, NASA's spacecraft "New Horizons", took it about 10 years and 10 months due to the orbit of Pluto being the closest to us at that time.
