Over 11.2 hours, the temperature changed -2.9 degrees each hour. What was the total temperature change? Enter your answer in the
Doss [256]

Answer:

Total temperature change = -32.48 degrees

Step-by-step explanation:

Over 11.2 hours, the temperature changed -2.9 degrees each hour.

Total time elapsed = 11.2 hour.

Temperature change per hour = -2.9 degrees

Total temperature change = Total time elapsed x Temperature change per hour

Total temperature change = 11.2 x -2.9 = -32.48 degrees

So temperature is reduced by 32.48 degrees in 11.2 hours.

Total temperature change = -32.48 degrees

vlada-n [284]
It is given that seismic activity d<span>ensity of a region is the ratio of the number of earthquakes during a given time span to the land area affected. so if the there 424 earthquakes and the land area is 71,300 sq miles.


seismic activity density = 424 / 71,300
</span>
<span>seismic activity density = 0.0059
the closest answer in the choices is 0.0056</span>
