## hannahbabiexoxo Group Title Algebra help please!!<333 last question and ill be done. I dont get it! :/ The volume of gas varies directly with temperature and inversely with pressure. Volume is 100 m^3 when temperature is 1508 degrees. and pressure is 15 lb/cm^2 what is the volume when the temperature is 2508 degrees and the pressure is 20 lb/cm^2 ? one year ago one year ago

You have to convert the sentences to a formula:$V=c \frac{ T }{ p }$ Put in the numbers of the first situation to calculate the constant c. Then put in the numbers of the second situation. You can calculate V now.

:D thanks

3. ZeHanz Group Title

Hope you understand now...

4. hannahbabiexoxo Group Title

kinda. Well, i do have a question. the constant C part. im kinda stuck o.o

5. hannahbabiexoxo Group Title

im kinda just stuck at how to plug in this first situation. from there ill be ok.

6. ZeHanz Group Title

First situation:$100=c \frac{ 1508 }{ 15 }$You can get c by multiplying both sides with 15 and divide by 1508.

thanks. alright, let me try this.

8. hannahbabiexoxo Group Title

by both sides you mean the 100 too right? Sorry. I ask so many questions lol D:

9. ZeHanz Group Title

Yes!

10. hannahbabiexoxo Group Title

ok well, i did that. Now...i dont divide that part by the 1508 right? :/ like i multiplied the 100 by 15 and got 1500

11. ZeHanz Group Title

12. hannahbabiexoxo Group Title

yes, i did that. so thats not wrong? I get nervous about math and i thought i did it wrong o.o ah good, so then, from there...

13. ZeHanz Group Title

So now try putting the new numbers in!

14. hannahbabiexoxo Group Title

ok!

15. hannahbabiexoxo Group Title

i put the new numbers in the formula right?

16. ZeHanz Group Title

Uhuh

17. hannahbabiexoxo Group Title

do i do anything with the number i just got. and the new number i got was the constant c right? would i just plug it in like, v=2508/20 or do i put the c in too.
