Given:

Intensity of earthquake is 5011 times more than

To find:

The magnitude of an earthquake that is 5011 times more than a standard earthquake.

Solution:

The magnitude of an earthquake:

$M=\log \left(\frac{I_{1}}{I_{0}}\right)

where I_1 is the measured intensity of earthquake and

I_0 is the standard intensity of earthquake

Given 5011 times more than a standard earthquake.

I_{1}=5011 I_{0}

Substitute this into the magnitude.

$M=\log \left(\frac{5011 I_{0}}{I_{0}}\right)

Cancel both I_0 in the numerator and denominator.

M=\log (5011)

M=3.6999

M = 3.7

The magnitude of the earthquake is 3.7.

Dima020 [189]

Answer:

Step-by-step explanation:

so the steps to doing this are as follows :

Subtract the accepted value from the experimental value.

Take the absolute value of step 1.

Divide that answer by the accepted value.

Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%

For the given statement, write the converse, inverse, and contrapositive. If a figure is a cube, then it had eight vertices.
Nastasia [14]
First, we recall what the terms converse, inverse, and contrapositive mean.
Conditional statement: If p then q.
Converse: If q then p.
Inverse: If not p then not q.
Contrapositive; If not q then not p.

Conditional statement:
If p then q.
If a figure is a cube, then it has eight vertices.

p = a figure is a cube
q = it has eight vertices

Converse:
If q then p.
If a figure has eight vertices, then it is a cube.

Inverse:
If not p then not q.
If a figure is not a cube, then it does not have eight vertices.

Contrapostive:
If not q then not p.
If a figure does not have eight vertices, then it is not a cube.
