## Question:

In an average year, worldwide, there are 134 earthquakes of magnitude 6 on the Richter scale. If next year is predicted to be an exceptional year, and the number of earthquakes of magnitude 6 is expected to increase by 36%, about how many earthquakes of magnitude 6 can be expected? (Round your answer to the nearest whole number.)

## Earthquake:

Earthquake is a natural phenomenon characterized by the sudden shaking of the Earth's surface. Earthquakes take place when seismic waves pass through Earth's rocks. One way of measuring the strength of an Earthquake is with the use of the Richter Scale named after Charles F. Richter. In the Richter scale, the Earthquake's strength is gauged in terms of its magnitude.

## Answer and Explanation:

Given:

{eq}n_0 = 134 {/eq} Number of earthquakes of magnitude 6 in an average year

To determine the number of expected Earthquakes of magnitude 6 by next year given its percent increase, we will the formula as,

{eq}n_1 = 134 + 134 (0.36) = 182.24 = \boxed {182 \ earthquakes} {/eq}
