We know that
if <span>points a and b lie on the circle  and O is the center
so
OA is the radius
OA=OB
5x-11=4(x-1)-----> 5x-11=4x-4----> 5x-4x=11-4-----> x=7
OA=5x-11-------> OA=5*7-11-----> OA=24  units

the diameter is (OA+OB)
2*OA------> 2*24------> 48 units</span>

the population of a town is 1,03.500 if 56%of the population is male find the number of females in the town
bija089 [108]
The population you gave isn't formatted correctly so I'll solve the problem assuming you mean 103,500.

First we find the number of males from the percentage given:

0.56 * 103500 = 57960 males

Subtract the number of males from the total population to get the number of females:

103500 - 57960 = 45540 females

You could solve the problem by finding the percentage of females first. Since there are 56% males, that means there are 100-56 = 44% females.

0.44 * 103500 = 45540

The answer is 45540.
