50 ways to leave your lover.

For e.g we draw a rectangle with length and width of 4cm and 3cm respectively. So the diagonal would be of 5cm(using Pythagoras theorem) and area 12cm^2. Now using algebra we can find the dimensions of the rectangle,Look below: let length=x let width=y so: x*y=12----(1) x^2+y^2=5^2----(2) x^2+y^2=25 Now simplifying the above equations: x^2=25-y^2 ---->x^2*y^2=144 ---->(25-y^2)*y^2=144 25y^2-y^4=144 y^4-25y^2+144=0 let y^4=z^2 so: z^2-25z+144=0 by simplifying the above quadratic equation: z=(25+(25^2-4(1)(144))^(1/2))/2(1) , z= (25-(25^2-4(144))^(1/2))/2 z=16, z=9 when z=16, when z=9 so y=4 ,so y=3 Now verifying which magnitude is correct for y: 12/4=x ,12/3=x x=3 not correct, because y>x x=4 is correct, because x>y
Draw a picture of this you will see that you can form a triangle with the radius of the circle being 1. This is the hypotenus of the triangle Using trig, x = cos 50 y = sin 50 P is (x,y) = P is (cos 50,sin 50) = (0.643, 0.766)
A triangle will always have a total of 180 degrees when adding all inside angles.corner x = 50corner y =75corner z = unknownx+y+z=180180-x-y=z180-50-75=zz=55 degrees
50 years is a golden wedding, 25 is a silver wedding? I know it says "gd" but I wonder...
25 years of marriage is a silver wedding.
Answer : 50 and -25 Let the two numbers be x and y with x > y. x + y = 25 x - y = 75.........adding these two equations together eliminates y 2x....= 100 : x = 50 Substituting for x in either of the original equations gives :- 50 + y = 25 : y = 25 - 50 = -25
Let the two numbers be x and y.Then;x + y = 100 -----(1)xy=25 -----(2)or x=25/yputting x=25/y in the first equation we get:25/y + y =10025 + y2 =100yy2 - 100y + 25 = 0x = 50 - 15sqrt(11) ; y = 50+15sqrt(11)orx = 50 + 15sqrt(11); y = 50 - 15sqrt(11)

50 Y is a G W means "50 yards is a good walk" and 25 is a S W means "25 is a short walk."
No, 50 is double of 25 so....if X = 50 Y = 25 X - Y = 25 25 / Y = 1 1 * 100 = 100% 100% is double. -------------------------------------------------------------------------------------------------------------------------------------------------- X = 50 Y = 25 X/Y = 2 X = 2 x Y <------- statement 1 X/Y = 2 X/Y = 2 x 100% = 200% X = 200% of Y <------ statement 2 By statement 1 & 2, 200% is equivalent to double.
25
50 years is a gold wedding, 25 is a silver wedding
25% of 50 you can go like this25 x 50 = xx / 100=y50 - y = answerAnother contributor's answer:25% of 50 is equal to 25/100*50 = 12.5
x + y = 39 x - y = 11 _________ 2x = 50 x = 25 y = 14
W x Y/60 miles Example: 30 mins at 50 mph W = 50 Y = 30 W x Y/60 = 50 x 30/60 = 50 x 1/2 = 25 miles
