By Pythagoras  AB^2 = 12^2 - 6^2 =  108

AB = sqrt 108 = 10.39 to nearest hundredth

The perpendicular from M to DC will be parallel and equal to AB so  it = 10.39.

Also  AB^2 = CB * DB

108  =  6 * DB
DB = 108/6  = 18
so DC = 18-6 = 12

MD^2 = (1/2*12)^2 + 108  =   144

so MD = 12

What percent of increase for a population that changed from 25,000 to 30,000
tiny-mole [99]

percent of increase for a population that changed from 25,000 to 30,000

Increase in population = 30,000 - 25,000 = 5000

So, the increase in population is 5000

To find percent of increase , we divide the increase in population by initial population.

So percent of increase = \frac{5000}{25000} * 100

= 0.2 * 100

= 20 %

20% of increase for a population that changed from 25,000 to 30,000.
