Thanks.                            

No.

Don't even try. Don't even try.

3(x-4) ≥ 5x+2

3x - 12 >= 5x + 2

3x - 12 - 3x - 2 >= 5x + 2 - 3x - 2

- 14 >= 2x

- 14 / 2 >= 2x / 2

-7 >= x

5^2 = 25

or u can calculate 5 x 5 = 5^2 = 25

its simple...

10 + 9 = 19

practice  multiplication tables!!!

You could just type this on the web2.0calc...

Would've helped a little if anon put some kind of unit after the 100,000...

$$\left({\mathtt{66}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{66}}$$

$${\mathtt{x}} = {\frac{{\mathtt{66}}}{\left({\mathtt{66}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}}$$          =>   $${\mathtt{x}} = {\frac{{\mathtt{66}}}{\left({\mathtt{66}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}} \Rightarrow {\mathtt{x}} = {\mathtt{0.99}}$$

Cone:  d=36  =>  r=18    ; h =12

$${\mathtt{V}} = {\frac{{{\mathtt{r}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{h}}}{{\mathtt{3}}}}$$       =>    $${\mathtt{V}} = {\frac{{{\mathtt{18}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{12}}}{{\mathtt{3}}}} \Rightarrow {\mathtt{V}} = {\mathtt{4\,071.504\: \!079\: \!052\: \!372\: \!037}}$$

$${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3.14}}{\mathtt{\,\times\,}}{\mathtt{4}}{\mathtt{\,\times\,}}\left({\mathtt{4}}{\mathtt{\,\small\textbf+\,}}{\mathtt{6}}\right) = {\frac{{\mathtt{1\,256}}}{{\mathtt{5}}}} = {\mathtt{251.2}}$$

the answer is 24

Zegreos is right that's why there is an APP link on the Calc home page.  

See that's why you got a 48% on the networking test.

I know, I know, you said 84%, but you have little dyslexia, so I corrected it for you. 

oh no! What are you thinking math god! Now melodies ego is even worse than before!

good luck...And dont worry about math man because you are a MATH GOD!

no sorry no app. Wouldnt be too good anyway because you would need a wifi connection to get the full potential of this site

thanks math. btw guys. Just got done with my networking test and i got an 84%....My 90's streak is broken
