The Richter Scale gives a mathematical model for the magnitude of an earthquake in terms of the ratio of the amplitude of an ear

Alexeev081 [22]

Answer:

The magnitude of the claimed earthquake would be 13.67.

Step-by-step explanation:

The 1906 earthquake had a intensity of A and a magnitude of 7.8.

S is going to have the same value, so i am going to write as 1. So:

$\log{A} = 7.8$

$A = 10^{7.8}$

$A = 63095734.448$

Many pundits claim that the worst is yet to come, with an earthquake 748,180 times as intense as the 1906 earthquake ready to hit San Francisco.

So $A = 748180*63095734.448$

$R = \log{A} = \log{748180*63095734.448} = 13.67$

The magnitude of the claimed earthquake would be 13.67.

Find the value of x in the given figure.

garri49 [273]

Sum measure of interior angles of traingle is 180° according to this rule ; sum measure of interior angles = (n-2)180 where n is the no. of sides

(3-2)180

=180°

$72 + 65 + y= 180 \\ 137 + y= 180 \\ y= 180 - 137 \\ y = 43$

The sum of an interior and exterior angle equals to 180°

According to this

$y + x = 180 \\ 43 + x = 180 \\ x = 180 - 43 \\ x = 137$

Hope it helps
