Answer:
The answer is below
Explanation:
1. A) The percentage increase in population in Hildago between 1997 to 2007 is:
Given that Hildago population in 1997 = 511, 324
Hildago population in 2007 = 726,604
Hence, the percentage increase is 726,604 - 511,324 = 215280
Then 215280 ÷ 726604 = 0.2962 ≈ 29.62%
1. B) For Willacy
Willacy population in 1997 = 19,332
Hildago population in 2007 = 20,600
Hence, the percentage increase is 20,600 - 19,332 = 1268
Then 1268 ÷ 20600 = 0.0615 ≈ 6.15%
2. The problem a rapidly growing population posed to a watershed are:
A. impaired water bodies
