I went to job corps and they taught me a trick to a math problem but I dont remember?

Think "percent over 100 = is over of."\n\nSample problems:\n\nWhat number is 30% of 40?\n"%" / 100 = "is" / "of"\n30 / 100 = n / 40\nn = 30(40) / 100 = 12.\n\n30 is what percent of 40?\n"%" / 100 = "is" / "of"\np / 100 = 30 / 40\np = 30(100) / 40 = 75.\n\n30 is 40% of what number?\n"%" / 100 = "is" / "of"\n40 / 100 = 30 / n\nn = 30(100) / 40 = 75.

First I wouls say that is not way you really left your first job.  Did not understand its product ?\nDepending on your job, you don't even have to know what its product is to do a specific job.\n\nBut if you don't understand you ask and research and find out.

Try looking it up in your math book if you need more clarity

that math formula that proves it is SO WRONG! i just talked about this with someone, if you look at the formula it gets messed up like halfway through.\n\ndo we need to break this down?\none fish + one fish = 2 fish

I left school a while ago, but isn't it (0,2).  2 on the y axis.

yes, I can.\n\nAnd so can you.\n\nWhat this problem says to me is that when she left store two, she had 1/4 of the money she had left after leaving store one which was $20.\nThat would mean that she had 4 times that much after she left store one.\nThat means she had $80 after leaving store one.\nThat means that 5/8 of her whole amount of money was $80 (because that was what she had left after spending 3/8 of it).\nSo that means that 1/8th of her whole amount of money was $16 (found by dividing 80/5).\n\nThat means 8/8 of her whole amount of money is $128 (found by multiplying $16 by 8).\n\nThat means she started out with $128...\n\nNow, show your work when you turn it in. \n\nOh, you still have to turn my answer into math terms. Good Luck.\n\nTo prove your answer work it backwards.\n\nAssume she started with $128.\nSpend 3/8 of it at store one. That means she has 5/8 left, so she has $128/8 then X 5 = $80 left.\nThen Spend 3/4 of the $80. That means she has 1/4 left. So 1/4 of $80 equals $80/4 which of course is....    $20\n\nOnce again the integrity of mathematics has been preserved.

The facts in this riddle are clear: There is an initial $30 charge. It should have been $25, so $5 must be returned and accounted for. $3 is given to the 3 friends, $2 is kept by the bellhop - there you have the $5. The trick to this riddle is that the addition and subtraction are done at the wrong times to misdirect your thinking - and quite successfully for most. Each of the 3 friends did indeed pay $9, not $10, and as far as the friends are concerned, they paid $27 for the night. But we know that the clerk will tell us that they were charged only $25 and when you add the $3 returned with the $2 kept by the bellhop, you come up with $30.

go into 'program' and make a new one.  you can save from there for formulas and programs you make.  get the manual and it will explain more

May be u r weak in mathematics!! or may b u took leave whn ur maths teacher taught u addition at school!!!

just work backwards to find out the logic in it. That way you'll get why it works that way it did

It didn't go anywhere.  \n\nThey each paid $10 to begin with- that's $30\n\n$25 to the hotel\n\n$2 to the bellhop\n\nthat's $27- which leaves $3 left over as a refund to the original three.\n\nThe questions is misleading becuase you add the $2 instead of substracting it.

me i alwas sucked at math

Took it last quarter, looked at it like a puzzle.  A puzzle is fun, math is not.  You start with the matrix given in the problem, and have to finish with ending matrix given.  Do what you need to do to get to the last matrix.  The best part, if you mess-up, just do another set.  There are no wrong answers, try doing it like a puzzle, more fun than Soduko.  Good Luck

you might have learning differents. You could be tested to see if you are then you could find help.  You could get a tutor or ask a teacher for help with math.

The answer should be 64350/184756 or 34.8%\nIs that what you have?\n\nTo solve this problem you will need a function called "choose", often written as C.\n\n20C10 means "given 20 items, how many possible combinations of 10 are there?".  If there are 20 questions and the teacher chooses 10 of them, then there are 20C10 possible combinations of questions on the test.\n\n20C10 is solved by 20!/[(10!)(20-10)!]\n\nThe solution to the problem is (15C8)*(5C2)/(20C10).\n\nThere are (15C8)*(5C2) possible combinations of 8 (out of the 15) questions that you do know and 2 (out of the 5) questions that you don't know.\n\n"Choose" functions are very long calculations so you should not be expected to do them by hand.  On a TI graphing calculator, use the nCr option under the MATH/PRB menu.

OK, let T be the time (in days) that the job takes.  You know that x can do one fourth of the job in a day, y can do a sixth, and z can do a half.  You have one job to do.  so the equation is set up:\n\n1/4T+1/2T+1/6T=1\n\n24 is a common denominator, so:\n6/24T+12/24T+4/24T=1\n\nNow add the fractions, you get:\n\n22/24T=1\n22T=24\nT=24/22, or 12/11 days (little better than 1 day)
