In 2010, haiti was hit by a devastating earthquake which registered at 7.0 on the richter scale. the largest recorded earthquake since 1990 occurred in 1960 in valdivia chile and registered at 9.5 on the richter scale. about how many times greater was the intensity of the chilean earthquake?

Approx 316.228 times

Step-by-step explanation:

Let be the intensity of the earthquake in Chile

And, be the intensity of the earthquake in Haiti,

Since, Haiti was hit by a earthquake which registered at 7.0 on the Richter scale and Chile was hit by a earthquake which registered at 9.5 on the Richter scale,

Thus, for Chile,

--------(1) [ by the formula,   ]

And, For Haiti,

----------(2),

Equation (1) - Equation (1),

⇒

⇒

⇒

⇒

That is, the Intensity of Chile is approx 316.228 times of intensity of Haiti.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
