Question

** PLEASE HELP ME ** WILL FAN & MEDAL!!
An earthquake with the rating of 3.4 can cause destruction in areas up to 100 Kilometers that are populated. *R=log x*
R = rating of the earthquakes size on the Richter scale
x = ratio of earthquake intensity to a minimum level of intensity.
What is the value of x when the Richter scale rating is 3.4? PLEASE help me through this

Answer 1

what have you tried so far?

Answer 2

I'm trying to set it up, I've put 3.4=log(x) but I don't know what to put for x?? It says x = ratio of earthquake intensity to a minimum level of intensity. what does that mean?

Answer 3

well the lowest level of intensity in a earthquake is obviously 0 and the highest to date was a 9.5 on the richter scale in shile in 1960, but im not sure if that would help much

Answer 4

chile* sorry typo

Answer 5

An earthquake with the rating of 3.4 can cause destruction in areas up to 100 kilometers that are populated. Does that have any clues in that?

Answer 6

I tried to put 100 as x..but that was wrong

Answer 7

depending on how populated but that isnt in the question so let me think for a second

Answer 8

well 100 kilometers equal up to 62.1371 miles which if you round up would equal 63 miles or 62 in a half

Answer 9

so should I make a ratio out of that to find x?

Answer 10

give me a sec

Answer 11

yea try that then tell me what you get

Answer 12

I don't know how to make a ratio in a calculator though

Answer 13

do you have a fraction bar on your calculator

Answer 14

and are you by chance able to help me with a question im dealing with

Answer 15

I can try, what is it?

Answer 16

i have to graph the linear equation (x-4y=-18) on a graph
