Let's see.\n\nTwo dimes and one nickel\nOne dime and three nickels\nFive nickels.\n\nYou can have five pennies in place of one nickel in any of the above sitiuations.\n\nSo you could have:\n\nTwo dimes and five pennies\nOne dime and two nickels and five pennies\nFour nickels and five pennies.\n\nBut once again, you can have five pennies in place of one nickel in any of the above sitiuations. (Now, D = dime, N = nickel, P = penny)\n\n1D, 1N, 10 P\n3N, 10P\n\nOne more time\n\n1D, 15P\n2N, 15P\n\nAnd again:\n\n1N, 20P\n\nOne last time\n\n25P\n\nI count 12 ways.

1275 may be the correct answer but not for that reason. i don't agree with the logic in finding the pattern. i have been trying to find the answer for the last 20 mins and will keep trying to find the answer but i want to know two things:\n\ndoes ab represent just the unknown number or is it a two digit number\n\nand are the numbers correct? \n\none more thing, how was this question written i.e. horizontally, vertically?\n\ncheers\n\nthe differences between each number starting from the bottom is \n4, 8, 200, 330 and the differences between those numbers are 4, 192, 132. so i can't get a guesstimate for you other than it should be around 1000 and probably ends in five.

You do like this.\n\nEasy example:\n4 / 2 = 2 (Remainder 0)\n2 / 2 = 1 (Remainder 0)\n1 / 2 = 0 (Remainder 1)\n\nTherefore, 4 (Decimal) is 1 0 0 (Binary)\n\nSlightly longer example:\n61 / 2 = 30 (Remainder 1)\n30 / 2 = 15 (Remainder 0)\n15 / 2 = 7 (Remainder 1)\n7 / 2 = 3 (Remainder 1)\n3 / 2 = 1 (Remainder 1)\n1 / 2 = 0 (Remainder 1)\n\nAnswer: 1 1 1 1 0 1

If this is for a statistics course, chances are you are allowed to run out 22.8 times.  If you must round, 23 would be more correct, but as answers never come out to integers in statistics, my guess is that you are to put the decimals.

2.7 repeating (this means that the 7's go on forever)\n\nFor all fractions that have a one digit number over 9, it is that number that will repeat on and on. For example:\n1/9=.111111111111111111111111111111111111111....\n2/9=.222222222222222222222222222222222222222...\n3/9=1/3=.33333333333333333333333333333333333....\n\nYou get it now? \n\nThe reason this might be hard is because the number repeats. To demonstrate that the number repeats, you put a line over the digits that repeat\n\nExample: \n3.3 repeating would have a line over the last three. \n\nIf it was 3.34343434, then the line would be over 34 because the repeats. This goes on. \n\nI hoped this helped. If it didn't email me and ask me another question I might be able to help on.

Before answering the question, consider another example of a rational number: \n11/7 = 1.571428571428571428....\nhere we see that we have a repeating pattern of 571428\nWhen we are dealing with rational numbers we must necessarily end up with a repeating pattern because there are only a finite number of possible remainders upon dividing any integer by 7. (i.e 0,1,2,3,4,5,6). But as we see, not all possible remainders must appear in the repetition pattern. That will depend on both the numerator and denominator of the rational number as we saw in your example 1/6 \nHowever, when we are dealing with irrational numbers (or irrational and transcendental like pi) it's a different story. Consider the sqrt(11), which is irrational:\nsqrt(11)= 3.31662479....\nNow consider sqrt(11)/3 = 1.105541597... \nwe see that first two digits are 1, and we also see that the 5 repeats itself. This is because, as with pi there is no fixed set of integer remainders when we divide the sqrt(11) by 3. When we divide an irrational number by a given integer (or an irrational number) we get a maximum integer + an irrational remainder which when carried over and divided by again by the given integer (or the irrational number) may give the same maximum integer(resulting in a repeating digit) but the new irrational remainder will not be the same as the last one, and we will eventually get a different maximum integer, so we never get repeating patterns as we do when dividing one integer by another.

If the difference is the same as one of the decimals in the problem, then a - b = b. So a = 2b. Your task is to find a way to write two decimals in a way so that one decimal is double the other.\n\nWith your teacher's hint, you only have to work with 0, 1, 3, and 5. Some trial and error later, you get 30 is twice 15. So the solution is\n\n4.30-2.15=2.15

4.4.........the zeros cancel themselves otherwise the answer would be 8 but because of decimal point locations, its just 4.4.....\n\n\nhow did u come up with the answer?

1. Bob's favorite ice cream used to cost $1.50.... Then the price was raised to $1.75. Find the percent increase.\n(175/150)-1)*100%=16 2/3% increase\n\n2. Jenny paid $12,000 for her car. Five yrs later she sold it for $8500. What percent decrease was this?\n(8500/12000-1)*100%= -29 1/6% 29 1/6% decrease\n\n3. The Music Box marked up their CD's 75%. If the music box charges $20 for a special cd, how much did it cost before the mark-up? (hint: the answer is not $15)\n$20=1.75x\nx=20/1.75=$11.43\n\n4. Quinn deposits $2000 in a savings account that pays 4% compounded semi-annuallly. HOw much money will Quinn have in her account after two years? Give the expression. (you do not have to simplify) \n\n$2000(1.02)^4=$2164.86

If there is no remainder, then this is a *whole number without a* decimal.  Or you could say that the decimal portion was zero.\n\ne.g. 27/3 = 9.0\n4/1 = 4.0\n-28/7 = -4.0\n-2/-2 = 1.0\n18/-3 = -6.0\n\netc.

There is no flaw as long as you recognize that .99999 repeats forever.  If you were to end it at some point and subtract, then as a previous poster said, you'd actually get 8.99....1.  But since it repeats, there is always another 9 and so it works.\n\nAnd consider this - if .9999999repeating did NOT equal 1, then there would be another number between them.  What would that number be?\n\n~~~~~~~~~~~~~~~~~~~~\nNo, the number in question is not infinitessimal, it doesn't exist.  You can never get to the end of the string of nines to try and squeeze another number in there :)

1,500,000 as a decimal is: 1,500,000∙0\n\nIf 3,000,000 = 0∙03% then;\n 3,000,000 = 0∙03%     (÷ 3,000,000)\n 1 = 0∙000, 000, 01%    (x 1,500,000)\n 1,500,000 = 0∙015%

Mutiply $28 by 0.30, then subrtact 28 again, and that should tell you how much it is. ($19.60. It will come up as -19.60 though, just ignore the negative)
