This problem uses the Richter scale for the strength of an earthquake. The strength, W, of the seismic waves of an earthquake are compared to the strength, W0, of the seismic waves of a standard earthquake. The Richter scale rating, M is given by the following equation: M=log(W/W0)

Now, consider the Caracas earthquake, which occurred in Venezuela in the year 1967 and had a Richter scale rating of 6.5. How many times more powerful were the seismic waves of the Caracas earthquake than standard seismic waves?

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
