1,000,000,000 miles/hour  x 140.000,000 years x 365.2422 days/year x 24 hours/day   miles in every direction

140 x 10^15 X 8,765.81281

1.22721 X 10^21 Miles in evey direction

Not really hard

3.1 x 10^17  / 6.3 x 10^11  = .492 x 10^6 = 4.92 x 10^5 years

On web2.0 calc   enter '3'  then mouse ove the 'log' button and scroll down to 'ln'   then '='

Let's re-write this as (pull the ' -1 ' out of the parentheses )

-a (c-b) + d(c-b)  then re-arrange

(d-a)(c-b)        Is THAT what you are looking for?

Not sure what you are asking....is this written correctly?  There is no variable.

Are you dealing in RADIANS?

Here is what I come up with

A 4 planes of symmetry

B  1/3 (6)(5)(3)   

C.......waiting for printout

D Using Pythagorean theorem  BD^2 = 6^2 + 5^2     BD=7.81   1/2 of BD =BF=3.905 cm

      TAN(FBP) = 3/3.905    FBP = 37.53 degrees

E  Pythag Theorem again  PB^2 = 3.905^2 + 3^2      PB= 4.924 cm

C  FM = 1/2 (6cm) = 3cm    so TAN (PMF) = 3/3 = 1   so angle (PMF) = ARCTAN(1) = 45 degrees

$h = price of the hat

$c = price of the coat, but the question tells us THIS equals 3 x $h

So.....

the total of these two prices must be 'less than or equal to' $120

$h + 3$h <= 120    We can simplify this a bit more by combining ' like ' terms

4$h <= 120         

'less than or equal to'    IS the inequality.......RIght?

b = #bananas    1.25b = price to pay for bananas

a = #apples         .75a = price to pay for apples

added together these prices must be less than or equal to $ 25

   Got it now?  Need more help????      

n= 1st odd integer

then n+2  would be the NEXT consecutive odd integer and

        n+4  would be the NEXT one after that

so  n   +    n+2   +    n+4   would be the sum of three consecutive integers (even or odd)  if three ODD numbers add to a certain sum(which is odd)  there will not be 3 consecutive even numbers that add to that sum (they would only add to a EVEN number)

So the answer would be.........?????     Got it?
