Yes it is always good when we get feed back of the question asker.  

Here's a proof that only the three digits 1, 2 and 3 are involved:

I haven't answered this question Denzel because it doesn't make sense to me.     

I could just simplify the ratio I guess

4.1:1.7  =     41:17

but that is probably not what you were after :/

Thanks Chris,

Mmm I can't think of any others either but I would like to see a proof or a concrete demonstration that there are no others.   

Thanks Geno.

I like questions like these.  

Many people are capable of trying them , if they are patient enough then they can probably get an answer by themselves, but if they look at your answer as well then they could learn a lot.    

These questions are great for gaining understanding of how numbers 'work'.

4x-8(y-2z)=4x-8y+16z

just remember that the - belongs to the 8

so this is really like        

4x+   -8(y-2z)

4x+     -8y  -8*-2z

4x+     -8y  +16z

4x - 8y +16z

It would also depend on whether it was U.S. doallars or Australian dollars or some other currency.  

If a recording of rap and hip-hop music is played in the desert and no one is there to here it, is it still obnoxious noise?

The ans is 94. 2x = 22 multiply by 2. 22 multiply by 2 is 44, thus the answer should be 44+50=94

The answer is 1/3.

hi anon,

This is an inverse function question                   (Factorials are something completely different)

Hi Anon,

It says sine theta of 1.03,  this is poorly written but I interprete it to mean sin of theta given that theta is 1.03

If it means     $$sin\theta=1.03$$    , as you have interpreted then there would be no answer because 

the range or sine theta is -1 to 1 inclusive.

Laoze,

The little hat means "to the power of"   it is standard notation.

It is often called a  'hat' but its real name of the character is caret

Hi MathsGod1,

Let me know how you get on with those videos :)

This is more engineering than physics, and I'm not sure I've made the simplifying assumptions the questioner was looking for!  Perhaps he/she will tell us.

Thanks Alan. :)

These physics ones always fascinate me.   

Does this help:

I've mistakenly used 200m for L instead of 1200m above.  With 1200m the flowrate becomes F ≈ 3050 kg/s.

Good morning Dbg4thebest and Alan !

x = 2.01333...         10 x =  20.13333...

10x - x = 9 x             20.13333... - 2.01333 = 18.12

9x = 18.12       =>   900x = 1812    =>      x = 1812 : 900 = 1812 / 900

  x= $${\frac{{\mathtt{1\,812}}}{{\mathtt{900}}}} = {\frac{{\mathtt{151}}}{{\mathtt{75}}}} = {\mathtt{2.013\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

 $${\frac{{\mathtt{1\,812}}}{{\mathtt{900}}}} = {\frac{{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{151}}}{\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{75}}\right)}} = {\frac{{\mathtt{151}}}{{\mathtt{75}}}}$$

Gruß radix !

It's alright. :D

Do you mean the 3's to go on forever?  If so, then try 604/300

$${\frac{{\mathtt{604}}}{{\mathtt{300}}}} = {\frac{{\mathtt{151}}}{{\mathtt{75}}}} = {\mathtt{2.013\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

.

$${\mathtt{29}}{\mathtt{\,\small\textbf+\,}}{\mathtt{24}}{\mathtt{\,\small\textbf+\,}}{\mathtt{24}} = {\mathtt{77}}$$

Yeah...

Its true. For understand the music of EMINEM you must understand or know some about his life. Some lyrics are explicit, 'cause he just find an out-stress on hip-hop and rap, especially hh. Slim Shady, his ALTER EGO is just another EMINEM that use the music for reprend the faults of his mother, father and with the wife. But its just sing.

yeah!! I had searched a lot for understand the difference between rap and hip-hop!!

cool!

good music!!!!

Thanks Alan.   

I don't remember seeing that formula before.    

Thanks Denzel  

Hardly anyone is around at the moment Dbg, all the U.S. children are on their summer break.  

$${\frac{{\mathtt{3.5}}}{{\mathtt{100}}}}{\mathtt{\,\times\,}}{\mathtt{19.4}} = {\frac{{\mathtt{679}}}{{\mathtt{1\,000}}}} = {\mathtt{0.679}}$$
