Answer:
The correct option is B) 0.0059 earthquakes per square mile.
Step-by-step explanation:
Consider the provided information.
It is given that seismic activity density of a region is the ratio of the number of earthquakes during a given time span to the land area affected.
If the there 424 earthquakes and the land area is 71,300 sq miles then find the seismic activity density for this state
This can be calculated by dividing the number of earthquakes with the land area.
Seismic activity density =
Here we need to round it to the nearest ten thousandth.
Thus the nearest ten thousandth is 0.0059
Hence, the correct option is B) 0.0059 earthquakes per square mile.

Answer:
Smaller angle = 53.2
Larger angle = 126.8
Step-by-step explanation:
Lets say x is the measure of the supplement. Since we know they're supplementary, we know their angle measure sum will equal 180. We can set up our equation like this . Note: (x - 73.6) is the measure of the smaller angle. By solving, we get 126.8 degrees for the measure of the supplement. If we plug in the value of x into (x-73.6), we get 53.2 degrees as the angle measure of the smaller angle.
