sorry the answer to the original question is 21,100,000. the example i used would be 22,000,000 because this has been rounded to the nearest 100,000 but in doing so we have reached another million, make sense?

math 5th grade
if we have a number that is 21,079,000 and we need to round to the nearest 100,000 then we are looking at this part of the number 21,(079),000. the 21 million has no effect on the rounding, so treat it as rounding 79,000 to the nearest 100,000. if the question was to round 21,...

lets start by multiplying out the brackets 8g+416-96=504+6g-84 then combine the like terms 8g+320=420+6g we then group the g's on one side and our numbers on the other 8g-6g=420-320 which leaves us with 2g=100 meaning g=50 hope this helped post back if u got any questions :)

well if F=ma and a=v-u/t (final velocity-initial velocity/time) so combining these two equations we get F=m(v-u/t) which gives us F=mv-mu/t if the car is to stop then obviously the final velocity is zero (now this will give us a negative answer but that is OK because it is a ...

if something dissociates then that means that it completely dissolves in a solution. so DrBob222 is completely correct as NaCl, MgCl2 and CaCl2 all dissolve. unlike table sugar. check a solubility table if you are ever unsure.
