Early in the 1990s, there was an earthquake in Los Angeles that measured 6.7 on the Richter Scale. The following year, Japan experienced an earthquake that was 5 times stronger. What was the magnitude of the earthquake in Japan? Use the example below to help you solve this problem.
Early in the century the earthquake in San Francisco registered 8.3 on the Richter scale. In the same year, another earthquake was recorded in South America that was four time stronger. What was the magnitude of the earthquake in South American?

I= Intensity of a certain Earthquake

S= the Intensity of a standard earthquake

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

answer:

125 yards

explanation:

75+50=125. that is my answer
