Answer:
B) The earthquake measuring 4.5 on the Richter scale is about 32 times more intense than an earthquake measuring 3.
Step-by-step explanation:
Let Ra = log(Ia/Io), and Rb = log(Ib/Io). Then for ...
Ra - Rb = 4.5 -3.0 = 1.5
log(Ia/Io) -log(Ib/Io) = 1.5 . . . . . . . . . . . substitute the given expressions
(log(Ia) -log(Io)) -(log(Ib) -log(Io)) = 1.5 . . . expand the logs
log(Ia) -log(Ib) = 1.5 . . . . simplify
log(Ia/Ib) = 1.5 . . . . . . . . write as a single log
Ia/Ib = 10^1.5 ≈ 32 . . . . take the antilog
The ratio of intensities is about 32, corresponding to choice B.
Answer:
x=1
Step-by-step explanation:
2(5x + 8) = 6x + 20
Divide each side by 2
2/2(5x + 8) = 6x/2 + 20/2
5x+8 = 3x+10
Subtract 3x from each side
5x-3x +8 = 3x-3x+10
2x+8 = 10
Subtract 8 from each side
2x+8-8=10-8
2x=2
Divide by 2
2x/2 = 2/2
x=1
