1,000,000 millimoles= 1 mole \ntherefore u'd need 50/1,000,000 * 147kg of calcium chloride \nie. 0.00735kg and since 1000g=1kg u multiply this by 1000 and that gives u 7.35 grams.\nhope this helps... cheers

v=vo + at\nv=0 + (9.8)(8)\nv=78.4\n\ny=1/2(vo + v)t\ny=1/2(78.4)(8)\ny=1/2(627.2)\ny=313.6m\n\nB

There are various means of determining this, and without any specific data on what elements are involved in the answer you are looking for, the link below is the best reference I can find that can answer this question in a mostly generalized way.

I figured it out... the answer is 1/(13*(2-3x))\nIf you need an explanation tell me

bring the a's to one side... u then get 9a = 27 ... divide and answer is a = 3

start with the O... they are always -2\nsince there are 2, and the compound must balance...\nPb must be +4\n\nso you get +4 -2

a = 0.5bc^2\n\n2a = bc^2\n\n2a/c^2 = b

1) Let x:the length , y:the width of the picture.Note:x,y>0\nThe first equation we have is : x=y+4 (1)\nThe combined area has the length is x+4,the width is y+4       \nso the second equation we have is: (x+4)*(y+4)=140 (2)\nReplace (1) in (2)-->(x+4)x=140--> x^2+4x-140=0 -->x=10 or x=-14 .since x>0 then x=10(cm)-->y=6(cm).\n2)  Let x: the length,y:the width.Note:x,y>0\n    The first equation we have is x=y+3 (1)\n    The second is: the area=x*y=550 (2)\n    Replace (1) in (2)--> (y+3)y=550--> y^2+3Y-550=0 --> y=22 or y=-25.Since y>0 then y=22(cm)-->x=25(cm)\n3)  Let x,y:two positive integers.Supposed that x>y>0 \n    we have two equation:x*y=240(1) and x=y+8(2)\n    Replace (2) in (1)-->y(y+8)=240--> y^2+8y-240=0 -->y=12 or y=-20.Since y>0 then y=12-->x=20.

This is not a higher education question.  if you are in higher education you should be able to figure out this question on your own.  Do your own work.

how does this fit into mathematics?

What exactly are you supposed to do with this equation?  Are you suppose to graph it, find solutions, factor or what?  You need to be more specific.

ok re arranged the second question so that the 6 is factored out so its x= such and such then sub the x equals such and such into the first equation and solve then do the same thing to Y in the second equation

It is similar to calculating the area. \n\nIt is a product of Length and Width (L x W).

lol  There is no answer.  I racked my brains at it for soo long.   Here are some sites to help you....

Take the 4x and introduce it to 7. Then ask y if it is equal to the sum of 4x and 7 if they like each other. If 7 is in agreement, then 4x can ask y to lunch and the intercept will all work out at the gym. 7 can go home with the question mark. Simple!

Start by multiplying both sides by D this gives you\n(D*P) = (2*s*t)\n\nthe divide both sides by 2t which gives you\n(D*P)/(2*t) = s\n\nor\n\ns = (D*P)/(2*t)

Problem: 17x=51\n\nsolution:  17x=51 (divide 17x  by 17 which will cancel out and will leave x by itself, then do the same for 51. so 51 divided by 17 is equal to 3.) you are left with x on one side and 3 on the other, therefore x=3
