On april 11, 2012, two earthquakes were measured off the northwest coast of sumatra. the first had a magnitude of 8.6. the second had a magnitude of 8.2. by what approximate factor was the intensity of the first earthquake greater than the intensity of the second earthquake?

0.40
1.02
1.05
2.51

Option D. 2.51 is correct.

Step-by-step explanation:

Magnitude of first earthquake = 8.6

Let intensity of first earthquake be x

Magnitude of second earthquake = 8.2

Let intensity of second earthquake be y

Now, to find the factor by which intensity of first earthquake is greater than intensity of second : we divide equation (1) by equation (2)

Hence the required factor is 2.51

Therefore, Option D. 2.51 is correct.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
