I think it is 1200 people. Because if 40% are female and there are 480 females, then do 480 x 2 and that equals 960 then half of 480 is 240 so add 960 to 240 and you get 1200 as the total amount of people there. I'm not sure if it's right, but it should be.
Proportional because there is no + x at the end<span />
What terms govern the length of this side?The basic rule of the triangle.First side length must be less than the sum of the other two sides.So to find X we must take the largest side of the triangles and compare them with amounts from other sides.
5+x>12
8+x>20 and it's system
x>7
x>12
general solution is x>12
<span>The least possible integral is 13.
PS: It's may be </span>yet 12, but in this case, triangle BCD become segment.
We analyze the linear function to find that it has equation

. Drawing the line, we find that it
will intersect the circle at negative and positive x-coordinates.We can prove this by
substituting 
into the given equation:




Hence,

or

, so there are both positive and negative values for

.
