  1. i dunno what you are even asking for #1-28, but this is quite a lot to ask for anyone here


  2. That's quite a of of help you're looking for!  Why don't you ask it in the math and science section?

  3. Do your own homework.  This is ridiculous that you would ask, and expect, someone to plod their way through 28 math questions.  When I was in school, we had to answer questions like this on our own, and you should too.

  4. you answer for number 6 is the answer for number 8. the answer for 6 is 0.117. the answer for number 9 is 23.72 not '123.72'. number 10 is 28.9 not 289, becareful with your decimal points.

    idk the answers for number 15, 17 ans downward cuz my math class really didn't require us to know those things. sorry but he other answers are right. if you want more help post this question under "homeowrk Help" or "Math"

    i hope at least i helped you with something! good luck
