Answer:

x = 53

Step-by-step explanation:

Assuming that the river is of constant width throughout.

x + (2x + 21) = 180

x + 2x + 21 = 180

3x + 21 = 180

3x = 159

x = 53

The population of a small town in Alabama is 382 people. If the growth rate is 0.7%, what will its population be in 30 years?
goldenfox [79]
Formula for growth:

y = initial • (percent growth + 1)^time/frequency of growth

So, since initial population is 382

Percent growth is 0.007

The time is 30 years

And it goes it by .07% every 1 year,

y = 382 • (1.007)^30/1

y= 470.9203732 people

Since we can’t have 0.9 of a person, the population after 30 years will be 470 people.
