Answer:

x = 27

Step-by-step explanation:

$30 \degree = \frac{1}{2} \{(5x + 10) \degree - (3x + 4) \degree \} \\ 30 \degree \times 2= \{(2x + 6) \degree \} \\ 60 \degree = (2x + 6) \degree \\ 60 = 2x + 6 \\ 2x = 60 - 6 \\ 2x = 54 \\ x = \frac{54}{2} \\ \huge \red { \boxed{x = 27}} \\$

The magnitude, M, of an earthquake is defined to be M=log I/S, where I is the intensity of the earthquake (measured by the ampli

Answer:

Step-by-step explanation:

Magnitude $M$ of an earthquake is defined as $M=log\text{ }\frac{I}{S}$ . Here $I$ is the Intensity of the earthquake and $S$ is the intensity of standard earthquake.

We have an earthquake that is 10 times more intense than a standard earthquake. Let us denote the intensity of the earthquake as $I$ .

10 times more intense than standard earthquake ⇒ $I=10S$

Magnitude of the earthquake = $M\text{ = }log\text{ }\dfrac{I}{S}\text{ = }log\text{ }\dfrac{10S}{S}\text{ = }log\text{ }10\text{ = }log_{10}\text{ }10\text{ = }1$
