First things first - you need to know the diameter of the rat. Remember C=PiD? Well, the rat's C (or girth) is 7.85 inches.\n\nNow you know the diameter of the cylinder of Spam the rat ate. Area of a cylinder is A=Pi(R^2)*L (Area equal Pi times Radius squared times Length) The length would be the thickness of each can, 3-1/4", minus 2 times 1/16 (the thickness of the can on each side) \n\nThat is the volume of Spam the rat ate in the first can, and he ate thru 11-1/2 cans, so multiply. This will give the total volume of Spam the rat ate in cubic inches. \n\nThen multiply the volume of Spam eaten in cubic inches by 1/5 pound per cubic inch, and you'll have the number of pounds eaten by the rat!\n\nGood luck!

The dimesnions of the rectangle are 14 feet by 34 feet.\n\nYou know that the perimeter is 96 feet and that each long side is 20 feet more than the short sides.\n\nAs there are 2 long sides the total length of both these sides must be 40 feet more than the total length of the 2 short sides (20 x 2 = 40).\n\nIf all the sides were the same length as the short sides then the rectangle would have a perimeter of 56 feet (we know it's 96 feet to start with and that the additional length on the two long sides is 40 feet and 96 - 40 = 56).\n\nEach side would therefore be 14 feet long since 56 divided by 4 = 14.\n\nNow that we know the length of the short sides all we need to do is add 20 to get the length of the long sides, 14 + 20 = 34.\n\nTo check it you can add 14 + 14 (the two short sides) + 34 + 34 (the two long sides) = 96.\n\nI hope that makes sense, it's 1:25AM here and I'm getting tired.

the truth about this is find the right formula for this equasion, then set it with ur need of what space you put it in to example : =sum(a1:a28)

N.O is wrong. The right answer is below:\n\n1st-you have to find the area of the plywood:\n   4.5*8.25=37.125 feet squared\n2nd-find the area of the circle he cut out:\n   A=pi*r^2\n   A=3.14*(1.5)^2\n   A=7.069\n3rd-subtract the area of the circle from the plywood's area:\n   A=30.056\n4th-mutiply this leftover area by 1.75 to get the answer:\n   1.75*30.056=$52.60\n\nSo his friend payed $52.60 for the leftover plywood!

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.

199\nIt's a simple algebraic sequence. \nLet x equal the number of bags, and let y equal the number of doubts\ny=2x-1\nso when x=100, y=100*2-1 =199

OH NOES THIS IS LIKE A MATH PROBLEM!!!! i can't handle any more variables :( sry.\n\n\nhahahaha.

1)  Notice that 6^2=6*6=36; 6^3=36*6=216; everytime you multiple a power of 6 by 6, the units digit remains 6.  Now what about powers of 5?\n\n2)  If r is total minutes and the first 3 minutes is $1.00, and the rest of r costs $0.20 per minute, then the total cost would be $1.00 + $0.20(r-3) = \n1 +0.2r + 0.6 =\n1.6 + 0.2r\n\n3)  3*10^4 = 3*10,000 = 30,000, and 4*103 = 412.\nNow divide 30,000 by 412 to get their ratio, and then multply that number by 100 to convert to percent difference.\n\n4)  Not enough info - you need the height too.  If the same height, obviously the can with the larger radius\n\n5.1)  65*20% =65*0.2 = 13\n\n5.2)  Again, not enough info. From the info given, all you can say about one-half the number of people who preferred green was that it was between 0 and (65-13)/2, aka 26

You SHOULD be able to do this for yourself.  Don't feel blown away simply because the result is large!\n\nWith your corrected list: 12,11,7,5,3,9,10, the lcm will be:\n\n12 x 11 x 7 x 5 x (1)* x (3)** x (1)***.\n\nThe REASONS?:\n\n* This is 1, not 3, because 12 already contains a 3.\n** This is 3, not 9, because 12 already contains a 3; so, to get a 9 in the final product, you only need one more 3.\n*** This is 1 because a 2 already exists in the 12, and the 5 needed to give you 10 in the end result has already appeared, as (plain) 5 itself.\n\nSo, to recap, the lcm is 12 x 11 x 7 x 5 x (1)* x (3)** x (1)*** i.e. 12 x 11 x 7 x 5 x 3 = 13860.\n\nIn future, use similar methods, don't just ask others to do it for you.\n\nLive long and prosper.

The long way to do this is much simpler:\n\n1) convert everything into inches and re-write the problem.\n2) do the easy math\n3) see how many times 12 goes into your new answer (that'll be the number of feet in your answer)\n4) then add on the remainder (that'll be the number of feet in your answer)

OK.\n\nThe problem specifies that x is the amount John gets a week, so we need to express everything in terms of how much John gets.\n\n"Peter gets twice as much pocket money as John"\n\nP = 2x\n\n"George gets $3 less than Peter"\n\nG = P - 3 = 2x - 3\n\n"Altogether the three boys get $17"\n\nx + P + G = 17\nx + 2x + 2x - 3 = 17\n\nYou can solve from there.

With this given data, it is not possible\n\nalthough the area is totalling to be 70 for both cases (7*10 and two pieces of 8*8 + 1*6) but with one division only, this is not possible\n\nPLEASE DO LET ME KNOW IF THERE IS SOME SOLUTION (i found it very interesting)

i assume you want a demonstration of the use of numbers and math in daily life... try these\n\n1. suppose brand a of candy sells for 2.37 for an 8 oz bag and brand b sells for 3.05 for a 11 oz bag ask audience which is a better deal ?, why ?, how can we compare the 2 brands to get a definite answer ? Now you introduce the idea of unit price which is $amount/weight do this for each brand. The smaller value for the two brands is the better unit price or the better deal.\n\nfind three different size circles. measure for each one the distance around the circle and the distance across the center of it write these values down for each circle.  Now for each pair of measurements divide the around value by the across value. ask the audience to compare the three quotients and note anything unusual.  what will happen is that no matter the size of the circle distance around/distance across is the same value about 3.14159. now state that pi is the ratio of dist. around / dist. across for a circle and is the same regardless of size of circle

I'd like to tell you a couple of tricks for getting ABOUT the right answer, which is often all you need, for instance when you're buying something and want to guard against a major cashier's error.\nMultiplying two numbers: Try to simplify the problem. Say it's 15 cans of something at 39 cents a can. Well 39 is pretty close to 40, so you get 15*40=$6.00. Or if you want it exactly, 15*40=$6.00 but subtract 15 cents because you added it when you simplified. $6.00 - $0.15 = $5.85. That's a lot easier than mentally multiplying 15 by 39.\nOften there seems to be no way to simplify the problem. Like 34 * $0.57. Well see what happens if you decrease one a little and increase the other by the same percentage. Say we take 34 down to 30, that's a little more than 10% less. Then what's a little more than 10% of 57? About 7. So we add 7 to 57, and we have 30 * $.64 = $19.20. The actual answer is $19.38. Again, not too bad. Or a 3-digit number: Try $3.79 * 18. OK, lets put $3.79 up to $4.00, about a 5% increase. Then take about 5% off 18 and it's 17. $4.00 * 17 = $68.00, compared to the exact answer of $68.22. \nHow about when you have a bunch of different items in the supermarket cart and you want the approximate total? Just keep track of the dollars and remember the cents as simple fractions of a dollar. So if you have these items: $1.39, $3.75, $2.19, $7.63, you say 1 & 1/3 plus 3 & 3/4 is 5 & a little; plus 2 & a little is 7 & 1/2; plus 7 & 1/2 is 15. The actual total is $14.96. Again, not too bad, although it won't always be this close. I hope you can use these. It gets easier with practice.

set up 2 equations with 2 unknowns and solve\n\none equation will involve the total poundage\nx + y = 9\n\nthe other equation will  involve your  costs with oh say the Right Hand Side having 9 * .96 as its value\n\n.... i want you to think on your own so this is as far as i go :)

I can't draw a diagram, but that would help.  So, picture the box and the corners.  Label the amount cut off (like the size) from each side x.  The new length on each side is going to be 11-2x or 14-2x (as there are two squares on each side).  These multiplied together (like a rectangle) form the area of 80.  Let's solve.\n\n(11-2x)(14-2x)=80\n\nExpand.\n\n154-50x+4x^2=80\n\nBring the 80 over\n\n4x^2-50x+74=0\n\nBring out the two\n\n2(x^2-25x+37)=0\n\nx is about 1.715 solving this equation.\n\nThere is actually another solution, somewhere around 10.8.  However, this is an unnecessary solution:  10.8*2 is obviously larger than both 11 and 14.  We can throw it out.  \n\nCheck that:\n\n(11-2(1.715))(14-2(1.715))=80\n\nThat's your answer.\n\nHope this helps.

Actually I had something to help you but x=0 which makes it pretty difficult.\n\nI guess you could try to talk about tomatoes or something.  Say Tom (X) has 1/2 the amount of tomatoes that Jill has, plus four.  Or in other words, if you take Jill's amount of tomatoes, multiply it by two, and take Tom's amount and multiply it by three, there total amount of tomatoes will equal 12.  How many tomatoes does Jill have?  How many does Tom have?
