There is a divide in there Afrikagurl   :(

Nor to worry - I'll give you some points anyway :)

Thanks Alan,  I have not quite got my head around your answer yet, I will try some more:/

Einstein, does 'exacly' mean 'thank you' to you?

OR  did you already know the answer and thought Alan, or someone else, needed some brain food?

I will certainly admit that it was a excellent question. :)

Universe = Universe + 1 - 1 

I don't understand the question.  Maybe I should but I don't.

Do you mean that the mark out of 40 and the mark out of 100 are just added together and the total out of 130 is turned into a percentage?

$$\\\frac{20.4+x}{130}=0.40\\\\
20.4+x=52\\\\
x=52-20.4\\\\
x=31.6$$

$${\mathtt{7}}{\mathtt{\,\times\,}}{\mathtt{4\,562\,189\,555\,554}} = {\mathtt{31\,935\,326\,888\,878}}$$

 266/1000 is 0.266 reoccurring as a fraction?

Its frustrating, rude and selfish!

Its GNO, she's the one who has acess to take that many point away...

Oh, and look who's giving 5 points to them selves!

Yeah, the way to a lot of point without effort and letting other's lose points.

Its just her habit guys.

(This comment will get -5)  -__-

It doesn't matter MG,

Who would lant to count all those cm anyway!   Plus you got it our eventually  

Thanks Alan 

Thank you Mistress Feather :)

We have

x^3 + (x + 1)^3 + (x + 2)^3  = (x + 3)^3  ...  and expanding, we have

x^3 + x^3 + 3 x^2 + 3x + 1 + x^3 + 6x^2 + 12x + 8  = x^3 + 9x^2 + 27x + 27  ....  simplify

3x^3 + 9x^2 + 15x + 9  = x^3 + 9x^2 + 27x + 27

2x^3 - 12x - 18 = 0

x^3 - 6x - 9 = 0   Using the Rational Zeroes Theorem, the possible roots of this are ±1,  ±3  and  ±9 

And  x = 3 is one solution

Using synthetic division. we have

3        1    0   - 6    -9

                3     9     9

          1    3    3      0

And the remaining polynomial  is   x^2 + 3x + 3   which has no "real" roots

So the integers are   3,4, 5    and 6

Check.....    3^3 + 4^3 + 5^3   =  27 + 64 + 125 = 216  = 6^3

20% of something is the same as mulitiplying something by 0.2  (20% = 20/100 = 1/5 = 0.2)

So 20% of 36000 is 36000 times 0.2 or divided by 5. Can you figure that out?

One hour...... To see why......Let's suppose that you either awoke at 12:30AM  or at 1AM......At each of these times you would have heard a "one."

If you awoke at 12:30AM.....the next "one" you would hear would be at 1AM......But you couldn't be sure if this "one" was to signal 1AM or 1:30AM......But, upon hearing the third "one"- 30 minutes later -  you would know that this sequence could only happen at 12:30 AM, 1AM and at 1:30AM

Similarly...if you awoke at 1AM......the next "one" you would hear would occur 30 minutes later - at 1:30AM. But, as before.......you couldn't be sure if this "one" was to signal 1AM or 1:30AM.......so you would have to wait until 2AM - when the clock struck "two" - to ensure the correct time.

In either case, you would have to stay awake one whole hour.......

2015-1995= your age

9*4=36 

if you put down your fourth finger it will show you your answer for fators of 9

left pinky = 9 fingers

left ring = 1 finger 8 fingers =18

left pointer = 36

right middle finger= 72

etc.

one half = ( 1 / 2 ) just use parentheses around the fraction and the division sign between the numbers 

This polygon is comprised of 30 congruent triangles, each with a central angle of 12°  

And using trig, each has an area of......

(1/2)(20)^2 sin(12°) = 41.5823381636 sq ft

So, 30 times this = 1247.470144908 sq ft  = 1247.5 sq ft  (rounded to the nearest tenth)

Scary......!!!!

also, Titanium Rome conquers the west part of the Atlantic, so yeah, you're under his rule

delaware punch, interesting

of course Titanium Rome would be clashing with Queen Izze of Spain, he's currently being wanted for drinking pepsi and root beer when by law of Spain, he should be drinking izzes

however, as you know, catching Titanium Rome is impossible, cuz he's bulletproof, and the Spanish only carry guns, and swords won't work on metal, and with the new titanium crystal armor, cannons won't stop him

Note....

5 log 2  =   log 2^5   = log 32  .... so  ...... n = 5

This is called a "factorial"......it is the procuct of all the positive integers up to, and including, "n"

For example.....  n!   ....  where n = 3....we have     1 x 2  x 3   = 6

Or  .....   n!  ....    where n = 4 =    1 x 2 x 3 x 4 = 24

This concept is very useful in statistics and probabilty in "counting" operations

BTW  ....   0!   is defined to be =  1
