4th grade math
oops, not 1.0492 * 104, but 1.0492 * 10^4

4th grade math
it's another word for scientific notation. It's "A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10. The scientific notation of 10,492, for example, is 1.0492 ¡Á 104."

English
yeah, basically

9th grade - Algebra???
standard form is ax+by=c. so just plug them all into that form. for example, the first one would be -14x-18y=24. you have to change the sign of 18 because you move it to the other side of the equation.

thanks

but is there any difference between them?

is disconformity and unconformity the same thing?

i got this from wikipedia: The stratosphere is a region of intense interactions among radiative, dynamical, and chemical processes, in which horizontal mixing of gaseous components proceeds much more rapidly than vertical mixing.

here's what i found on the interent: In Aruba the newspapers almost never publish a weather report. They don't need to. Around here, "sunny and warm" is not news. With an average rainfall of less than 20 inches a year, an average daytime temperature of 82&iex...

I just know that "The lactic acid system is capable of releasing energy to resynthesise ATP without the involvement of oxygen and is called anaerobic glycolysis."

you mean what is aruba's latitude and longitude? it's 12¡ã30' North and 69¡ã58' West.

usually, which is younger, the pebbles in sand, or the sand surrounding the pebbles? I think it's the pebbles in sand.

since y=mx+b..

isn't it y=5x+6?

I'm posting things cuz i suck at math. I did: 2-0.12b-1.2b=-3 2-1.32b=-3 -1.32b=-3-2 -1.32b=-5 b= -5/1 divided by 1 32/100 b=-5/1 divided by -132/1 b=5/1 * 1/132 b=5/132

math
no, i got 5/132.

math
yes.

math
no, I mean what do you get when you do this: 2 - 0.12b - 1.2b = -3.

math
when you plug in a=2-3/25b in the equation a-1.2b=-3, what are you supposed to get?

math
no, that is not what I do. You don't know anything about me, why do you care?

math
how do you combine the like terms?

l=68/l+5 what do you get if you want to combine the ls?

thank you, i get it now

but forming one for the perimeter would be 2L+2w=34.

aren't you supposed to form it for the width?

ok then thanks

math
what if for one equation it's 3=5, and for another it's also 3=5?

math
oh,ok.. let's say for one equation you get 2=2, and for another, you get 4=4.is the ordered pair a solution of both equations?

math
what does it mean for an ordered pair to be a soltuin of both equations? for example,for this system, is the ordered pair a solution of both equations? (2,2.4) 4x+5y=20 2x+6y=10

8/5b=15 if you want to isolate b, then b=75/8?

Please Help!!
it's barnes and nobles.

math
ok, i just don't get the whole problem: Solve this system using substitution. Check your substitution. C(n)=-3n-6 C(n)=n-4

math
if n=-2, then in C(n)=n-4, you just have to do C(n)=-2-4, right?

Social Studies
what are Ponhatons?? I googled it and there were no results at all..

science
well, to find an epicenter, first you have to measure the distance between the first P wave and the first S wave. So, that's how you have to use seismic waves to determine an earthquake's epicenter.

science
well, buildings on soft sediment is not good in earthquakes. when a building has a steel-frame it's safer..andbeing made of wood is also good.

stare=state agian=again sorry

science
then it gets stretched out..and the rcoks will never return to it's original stare agian. like a rubberband. if you stretch it too hard, when you stop stretching it, it still won't look the same.

science
primary waves arrive first. then secondary. then seismic. seismic also does the most damage.

science
1.primary 2.secondary 3.seismic
