Welcome, quilly!  

  This site has been around for about 5 years. It is a MATH forum where you can get any MATH questions you may have answered by real people. Anyone who happens to be signed on can answer (or attempt to answer), your Q's.  The answers may have an explanation (usually...but not always).......and there are no guarantees they are correct....but they usually are.

  Please try to keep your posts related to MATH if possible....if you have a follow up question about an answer you have seen posted, please post in to the original thread to avoid confusion and clutter on the forum site.  Please ....DON'T post the same question multiple times.   Sometimes looking at others Q's will find the answer for which you are looking.  We are not here to do all of your homework, but rather here to assist you with understanding your homework so YOU can do it.

  This is not a dating site, so please message someone from the Messaging Center if you need a slightly more private venue.

  It is also not a forum for posting poems, jokes, songs, tirades or religious musings....try to keep it 'Math-y' 

I have never used Yahoo Answers, so I do not know how it compares !

Have fun ! 

Quartile is often a 25% portion of 100%  (1/4.....quartile) ...often spoken of when dealing with statistics and bell curves...

Here is Wikipedia description:

(4, infinity)

Scien not for numerator  256  x 10^-5

Scien Not.for denom         16 x 10^1                16 goes in to 256  16 times

Result =  16 x 10^(-5-1)  = 16 x 10^-6    = .000016

I looked this up:

The properties of the trapezoid are as follows:

The bases are parallel by definition.

Each lower base angle is supplementary to the upper base angle on the same side.

SO angle a + angle d = 180

         angle a = 2d    substitute

              2d +d = 180       d= 60

    a= 2d = 120 degrees                                    This assumes your trapezoid is labeled    A            B

                                                                                                                                          D                      C

I will answer this tenatively , as no one has yet.....

To get from circle one to circle two, you will need to

Translate 10 to the left  (8-(-2))    AND

Translate DOWN 4   (5-1)    AND

introduce a dilation factor of 1/3     (1/3 x 6 =2)    

(x+6) /(sqrt(x^2-3x-4) )

Has a domain for ALL x such that the denominator does NOT equal Zero..AND we do not have a NEGATIVE sqrt

let's find what those values are

sqrt(x^2-3x-4)  = sqrt(x-4)(x+1)       This WILL equal zero when x = 4 or -1 <------ NOT allowed !

ALSO from    - infinity to +4 is invalid as a negative sqrt will result

to NET it all out , the domain is         4< x  thru  + infinity

If you're buying a pie that is 20% OFF...you wind up paying 80% of the ORIGINAL price

$18 x 80% = 18 x .8  = $ 14.40     

You would SAVE 20% of the original price

$ 18  x  20%  = 18 x 0.2 = $ 3.60

Just COUNT them...as written this is an EXPRESSION with TWO terms.    'u'    and   '5s'

A ONE MOLAR solution has ONE MOLE dissolved in 1 liter of solution.

Silver nitrate wieighs   107.868 + 14.007 + (3)15.999 = 169.872 gm/mole

169.872 gm/mole x .25 mole/liter x 500/1000 l  =  21.234 gm
