one more proportional math problem help?

if you use the common denominator method , \nyou get\n\n3x/21 = 35/21\n\ntherefore 3x = 35 \n\nx = 35/3\n\n if you cross multiply you will get the exact same thing, but in other cases its not feasible to find the LCD and solve that way. Its not a good approach since you will end up with large fractions.\nlets say for example\n\nx/2773 = 1893/3926 \n \nThe least common denominator for this thing would just be a waste of ink

Add them together and divide by 5.\n\nWow. I could seriously have you people do my homework for me. Every night. I'll type out the problems and see how you all do. :P JP

You mean "one less."\n\nCall the base x.\nThen each leg is 2x-1.\nAnd the perimeter is x + (2x-1) + (2x-1), which equals 18.\n\nJust solve for x and you can calculate the lengths of the sides.

SOrry, I can't help you. If I had the formulas I could do it, but there is no way I remember that off the top of my head! Good luck

I posted these sources earlier to someone else who was looking for math help.\n\nGood Luck!!

proportions.\nFirst cross multiply \nyou have 3*1= 3  and 2*x= 2x  \ndivide by 2.  =1 1/2

The first part of the question is telling you that you have a circle that has a circumference of 56cm, but it could be off by 1.2cm, give or take. The want you to find what percent it is.\n\nFor the math: (1.2/56)*100 \n\nor, using proportions  1.2/56  =  x/100\n(Setting the fracions upright, cross multiiply, solve for x)\n\nFor the next one, they are saying that the circumference can be off by 3%. In this case: (3/100)*56\n\nor, using proportions: x/56 = 3/100\n\n**For setting up basic proportion, you measurments have to be on one side and your percents have to be on the other.\nmeas./total meas. = percent/total percent

Since they r similar,\n\nDivide the Area of the larger cylinder by the smaller one,\n49(3.142)/25(3.142) to receive proportionality\n\n= 1.96\n\nTherefore 1.96 * volume smaller cylinder,\n\n1.96*50(3.142) = 307.8 = 98(3.142) [The Volume of the larger cylinder]

by any chance is this a question from your maths homework? lol :D\n\nI cant work it out myself because to put it simple, im crap at maths.

9100/.28 = 32,500\n\n9.50/1.25 = 7.60\n\nUsing proportions:\n1) 28/100 = 9100/x\n2) 125/100 = 9.50/x

Let me give you a hint.\nDivide 2.49 by 12.\nThen multiply by 5.\n\nOf course you could use fractions?

Tackling the problem bit-by-bit:\n\nFirst, let x = the larger number\nlet y = the smaller number\n\nYou can write out an equation to show their relationship of "difference" by:\nx - y = 68\n\nNext, you write out the equation to show their quotient relationship by:\nx/y = 5\nwhich gives:\nx = 5y\n\nNow plug x = 5y into the "difference" equation:\n(5y) - y = 68\nwhich gives\n4y = 68\nwhich gives \ny = 17\n\nNow plug y = 17 into the "difference" equation:\nx - 17 = 68\nx = 85

Use a calculator - numerator divided by denominator will give you the answer.

A = P + Prt\n\n==> P(1 + rt)\n\n==> P = A/(1 + rt)\n\n<done>
