Answer:
The intensity of the 2012 earthquake was about 126 times the intensity of the 1952 earthquake.
Step-by-step explanation:
To compare the intensities, we first need to convert the magnitudes to intensities using the log formula. Then we will set up a ratio to compare the intensities.
Convert the magnitudes to intensities and convert to exponential form.
R=logI
2012 earthquake:
8.6I=logI=108.6
1952 earthquake:
6.5I=logI=106.5
Form a ratio of the intensities.
intensity for 2012intensity for 1952
Substitute in the values and divide by subtracting the exponents to find
108.6106.5102.1≈126.
The intensity of the 2012 earthquake was about 126 times the intensity of the 1952 earthquake.
Your answer:
The intensity of the 1952 earthquake was about 110 times the intensity of the 2012 earthquake.
Answer:
4. 61
5. approximately 43
6. 120
Step-by-step explanation:
4. 80 + 39 = 119
180 - 119 = 61
5. 7x - 10 = 90
+10 +10
7x = 100
divide by 7
x = 14.3
3 times 14.3 = 42.9
6. 70 + 50 = 120
180 - 120 = 60
180 - 60 = 120
