you should LEARN to do them. If we just give you the answers then you learn nothing. If we TEACH you the answers, then you dont have to post your HW every night...

in my opinion he needs to do his own HW. He can ask for help, but not the answers, thats just cheating yourself...

(3/5)Sam = Joe

5 + Sam = 1.5(Joe + 5)

5 + Sam = 1.5( (3/5)Sam + 5 )

Sam = 25

Joe = 15

umm yea, that might be it, I just did it quickly mayb ill do the others later

heres the math i did.

19.12 * 1.05 = 20.16

20.88 * .95 = 18.836

18.836 + 20.16 = 39.996 which would round up to $40 at a register

Pentagon has 540 degrees

each angle has 540 divided by 5 = 108

square has 360 degrees divided by 4 = 90

360 - (108 + 90) = 162

So angle CAB is 162

but we know its isocelese (sp?)

so the other two angles equal eachother and plus 162 equal 180 (triangles have 180 degrees)

2A + 162 = 180

ABC = 9 degrees

or 1.05x + 0.95x = 40, so 2x = 40, x=20. The cheaper book is therefore 0.95(20) = 19

your math problem is wrong anyways. if the cheaper book is 19, then

19 * 1.05 = 19.95

then 21 would be left, so 21 * .95 = 19.95

19.95 + 19.95 does not equal 40 bro

my mistake. take that back. the orignal have to be equal, the 5% don't have to add up to 40 i guess

I'm wrong, he's right. My method allows the numbers to add up to $40 after applying the 5% increments, which isn't really what the problem was asking. should have actually read it more carefully

19 and 21 are the values, so $19 is correct..

Not at all..at least not at the school I'm from. i had algebra 2 my freshman year, along with probably about 1/4 of my grade, everyone else had it in 10th grade. Junior/Senior math is usually precalc/Calc AB/Calc BC.

6.

sin(90)/100 = sin(45)/x

1/2x * 1/2x = area of square.

If you want an easy way out of #4 and want to look smart, tell your teacher that you cant' do it since you don't know if it is in a single plain or if the two shapes were in independent planes at an angle to each other.

no its not junior level. i'm in advanced 10th grade (junior) and that is math 3, so math 2 has to be sophomore level.
