Answer:
Explanation:
Given that:
Area = 475 acres
The length of the channel (L) = 6870 feet
The average water shield slope (S) = 100 feet/mile
Since; 1 mile = 5280 feet
Burst duration D = 15 min
∴
100 feet/mile = 100/5280
The average water shield slope (S) = 5/264
Using hydrograph method:
The time of concentration 
where;
L = 6870
S = 5/264
min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time 
The time to peak i.e
Since D = 15 min is not equal to 
, then we hydrograph apart from duration lag time.
Then;
Now, we need to determine the peak discharge 
by using the formula:
where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²
∴

The FTA stands for Free Trade Agreement. Canada and the United States established this trade agreement in 1988.

In 1998, Canada and the United States extended FTA to form NAFTA, hich established a free-trade zone with Mexico.
Answer:
- Divergent plate boundary, which causes volcanic activity and shallow earthquakes.
- Convergent plate boundary, which has one plate that “dives (‘subducts’) beneath the other, resulting in a variety of earthquakes and a line of volcanos on the overriding plate”
- Transform plate boundary, where plates slide laterally past one another, producing shallow earthquakes but little to no volcanic activity.
- Hotspot, “where a plate rides over a rising plume of hot mantle, creating a line of volcanoes on top of the plate.”
