The Los Angeles area experiences many earthquakes. In 1994, the Northridge earthquake measured 6.7 on the Richter scale. In 2014, Los Angeles experienced an earthquake that measured 5.1 on the Richter scale. Compare the intensities of the two earthquakes. Use a logarithmic model to solve. Round to the nearest whole number.

Step-by-step explanation:

= Magnitude of 1994 earthquake = 6.7

= Magnitude of 2014 earthquake = 5.1

= Intensity of 1994 earthquake

= Intensity of 2014 earthquake

= Zero-level earthquake the same distance from the epicenter = 0.001 mm

Magnitude is given by

Dividing the above intensities with each other we get

The intensity of the earthquake in 1994 was 40 times stronger than the earthquake in 2014.

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours

its kinda hard to answer this when we dont have all the information that we need.
