does anyone know how to make 50 out of four nines. i need it for my homework but i can figure it out?

With just ! (Factorial), +, -, * and /, it is impossible to get 150 using only 3 5s without the x^2 (Squared) operation (Which means x*x, in case you are in Fifth Grade), or using a '^2' as you say. If you say there is an alternate way, and there really is, then I give up and admit defeat. (I'm sure most others do.) If you are so sure, why don't you post the answer yourself?

40-3=37 the number of correct answers\nset in to a proportion let x = the % correct\n37/40=x/100\nCross multiply\n3700=40x\nDivide both sides by 40\n3700/40=92.5\n40x/40=x\nthere for x=92.5\nso the student got 92.5% of the questions correct\nNote\n the # of points each question is worth does not matter

Multiply the top and bottom by the same number.\n50% = 1/2\n1/2  = 2/4 = 3/6 = 4/8 = 50/100

okay first convert mixed numbers to improper fractions so you have 9 2/7 and that equals 7*9+2=65\n\nso you have 65/7*7/8\n\nmultiply 65 by 7 and get 455\nthen 7*8 and get 56\n\nso you have 455/56\nconvert the improper fraction to a mixed number take 445/56 and you have 8 with a remainder 7\nso 8 and 7/56= 8 1/8  check ya later ♥

Several ways:\n\n(9 / 9) + 99 = 100\n99 / .99 = 100\n(9 / .9) * (9 / .9) = 100 \n\nhttp://www.iit.edu/~smart/acadyear/puzzles.htm

4/52*4/51*4/50 = 482.65 times in one million trys or 0.048% chance.\n\nhope that helps.\n\nm

(50p9q5)/(10pq2)\n\n= (50p/10p)*(9q/q)*(5/2)\n= 5*9*(5/2)\n= 225/2\n= 112.5

That's an easy one.....lets see... 36 times 3.14 gives about 100....divided by 3 gives about 30 times 3 is 90 divide by 10 gives 9cm ! Peace of cake !

I'd set it up like this...\n36      80\n--   =  --\n n      100\n\ncross multiply and solve for n

To solve this problem, you have to do ratios. Now, according to the image, do the ratio: small/long for one diagonal = small/long for the other diagonal. In this case, 6/10 = 5/x. Cross multiply to get 6x = 50. x = 50/6 or 25/3. I can't see the answer choices provided because they're so small but I can gurantee that the answer is 25/3, which i believe is c

3/5(10x-4)+1/5=49\n        -1/5    -1/5\n\n\n3/5(10x-4)=48+4/5\n  Foil\n\n30x/5-12/5=48+4/5\n     +12/5    +12/5\n\n30x/5=51+1/5\n  *5      *5\n\n30x=256\n/30   /30\n\nx=8+8/15\n\n\nsomebody wanna double check?  Pay attention in class more kid. Dont forget to double check it, I've always been too lazy too.

How do u change...\n4% into a faction- 4/100=2/50=1/25 If you reduce to lowest term\n\n9/10 into a percentage= 90%\n65% into a fraction 65/100 and reduce it\n1/5 into a percentage 30%\n1/8 into a percentage 12.5%\n78% into a fraction 78/100 and reduce\n35% into a fraction 35/100\n\n\n& how do you find an equivalent value of...\n44%\n3/5\n13/40\n11 1/9%\n&\n3/8\nCan u PLEASE! answer all of my math questions -A.S.A.P!

Ok, take it back.\n\nFlip the 6, turn it into a 9.  Move it over to the right hand side, move the 2 to an exponent over the 7.\n\n7^2 = 49.\n\nThat's it.

100 - 40 = 60\n\nTake $999 times 60, and place the decimal two digits to the left.\n\n\nI♥♫→mia☼☺†

Using proportions you can do the math later to find out how to get to the numbers, but basically it goes something like this;\n\nA = 4.00 - 3.50 = 100% - 90%\nB = 3.49 - 3.00 = 89% - 80%\nC = 2.99 - 2.50 = 79% - 70%\nD = 2.49 - 2.00 = 69% - 60%\nF = 1.99  -  0    = 59%  -  0%

You have to find a common denominator before you can add them together by hand. In this case it is 180. Use this to convert the terms:\n1/4 = 45/180\n1/9 = 20/180\n1/2 = 90/180\n4/5 = 144/180\nNow that they have the same denominator, you can add them together:\n45/180 + 20/180 + 90/180 + 144/180 \n=299/180 or in decimal form: 1.66111\n\nPlease give me 10 points!
