Yep! THX hectictar! and why is your username hectic-tar..... tar isn't very hectic in my experience...

Thank you! but you found the volume, and you added.... so thx for trying! The question asks for the surface area and subtraction tho...

1) one is kinda easy..... just start dividing and find a pattern. I found the pattern 0.370 repeating, and so your answer for 1 would be 0.3703703703

2)So I started manually dividing and after 6 digits, I stopped... I want to show it here but have no idea how... :( but your answer is 923076

3)to convert 0.045 repeating 5 to fraction form, just do this:

       1000x=45.55555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555

             - x=0.045555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555

              _____________________________________________________________________________________________________

subtract and get 999x=45.1

                                 x=451/9990

                                 x=41/90

4) $6032_8$ to decimal?! argh! ok, so start by doing (6*6^3)+(0*6^2)+(3*6^1)+(2*6^0)=1407.... and 1407 is 6032_8 in base 10.... in other words, decimal.

5)$999__16$ok I cant get the base thing to work in latex... so deal with this.

(9*16^2)+(9*16)+9=2457 in decimal..

6)35/2=17r1

  17/2=8r1

   8/2=4r0

   4/2=2r0

   2/2=1r0

   1/2=0r1

so i think 35 in base 2 is 100011

7)10101101...

OK, IM guessing this is from AoPS from the dollar signs...... I don't really mind the asking and I would solve it but can you edit it so the latex is in latex???????? ok so this is my version of it...:

1.) Find the first ten digits after the decimal point in the decimal expansion of $\frac{10}{27}=0.abcdefghij\ldots$

 without a calculator.

(Express your answer as a ten-digit number.)

2.) The number $\frac{12}{13}$ can be expressed as a repeating decimal $0.\overline{abcdef}$. Find the repeating part $abcdef$ without a calculator.

3.) Convert $0.04\overline{55}$ to a fraction in simplest form.

4.) Convert $6032_8$ to decimal.

5.) Convert $999_{16}$ to decimal.

6.) Convert 35 from base 10 to base 2.

(You do not need to include the subscript 2 in this answer.)

7.) Convert $2231_4$ to base 2 without first converting to decimal.

OHHHH I RESPONDED IN hours IM A IDIOT!!!!! The question asked for minutes! that's why I got such a small answer!!!!!! ohhhhhhhhhhhhhhhhhhhh.... :P

 ok so we have 0.025 of an hour which is 1.5 minetues.... much more reasonable!~ THANK YOU MELODY
