How might geologist in china and australia geologist in japan determine where an earth quake has occurred a)by using seismic data from several locations scientist can determine the epicenter of an earth quake b)chinese and australian scientist can go to japan to them analyze their sesmic data c)chinese and australian scientist can study the damage caused in their own countries. d) these scientist can determine the earthquakes location by the shking they feel at their locations.

Option: A is correct.

( by using seismic data from several locations scientist can determine the epicenter of an earth quake).

Step-by-step explanation:

" The size or magnitude of earthquakes is determined by measuring the amplitude of the seismic waves recorded on a seismograph and the distance of the seismograph from the earthquake "

Hence option A is correct. ( by using seismic data from several locations scientist can determine the epicenter of an earth quake).

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
