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.
You set up a proportion problem... 30/ Y = 60/100 You are solving for Y and the 60/100 represents 60% You just cross multiply (i.e. 30 x 100 = 3000) And divide (i.e. 3000 / 60 = 50) This is your answer! 30 is 60% of 50
10 Units.
It is simply: 50/y meaning 50 over y
-50
probably 100 yards
At first glance, this would appear to be a multivariable problem. But in actuality, with the two equations we have to work with: f(x,y) = xy x - y = 100 We can rearrange the second one to find what y is equal to in terms of x: y = 100 - x (We can also solve x in terms of y, but solving y in terms of x is conventional). then we can plug this in for y into f(x,y) to make it simply a function of x: f(x) = x(100 - x) = 100x - x2 We then take the derivative of this, setting f'(x) equal to 0: f'(x) = 0 = 100 - 2x 2x = 100 x = 100/2 = 50 This is the value of x that minimizes the product of x and y when x - y = 100. We then solve for y by plugging in the x-value into this equation: 50 - y = 100 -y = 100 - 50 y = -50 By plugging in values for which x > 50 and x < 50 into the equation f(x) = 100x - x2, we find that f(x) is indeed greater on both the intervals where x < 50 and where x > 50, proving that x = 50 is indeed an absolute minimum.

This is more complicated than it first appears. You cannot simply add percentages together - you need to know what they are percentages out of. So if you have x% being a out of b so that x = 100*a/b and y% being c out of d so that y = 100*c/d Then the sum of the percentages is 100*(a+c)/(b+d). The clearest way to see that you cannot simply add up the percentages is, if you get a 50% score in one exam and a 50% score in another, you do NOT get 100% in the two exams combined!
Dcclii d=500 c=100 l=50 i=1 d + c + c + l + i + i = 500 + 100 + 100 + 50 + 1 + 1 =752!
% of x in y = (x/y) * 100....Here, we wish to find the percent 46 is of 92, so, x= 46 and y=92=> required % = (46/92) * 100 = 50
L=50 C=100 D=500 M=1000. Memorize the sentence "Liquid Crystal Display Monitor or LCD Monitor-where L=50, C=100, D=500 & M=1000.
50 = L 100 = C 500 = D Remember the sentence Liquid Crystal Display Monitor OR LCD Monitor wherein L=50, C=100, D=500, & M=1000
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)
if you get 50/100 then you FAILED sorry to tell you.
x/y*100=% For example: 45/90*100=% 1/2*100=% .5*100=% 50=% Check: 50% of 90 = x 50/100 * 90 = x .5 * 90 = x 45 = x
