In 2010, Haiti was hit by a devastating earthquake, which registered at
7.0 on the Richter scale. The largest recorded earthquake since 1900
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?

316 welcome

Step-by-step explanation:

The answer is D. 316

Step-by-step explanation:

I got it right on ed.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
