On the Richter scale, the magnitude, M, of an earthquake is given by M= 2/3logE/Eo, where E is the energy released by the earthq
Ivahew [28]

Answer:

See below

Step-by-step explanation:

Part A

<em><u>Formula</u></em>

M = 2/3 * log(E/Eo)

<em><u>Givens</u></em>

M = ??

E = 2 * 10^15 joules

Eo = 10^4.4

<em><u>Solution</u></em>

M = (2/3) * log(2 * 10^15 / 10^4.4)

M = (2/3 ) log (7.96 * 10 ^ 11)

M = (2/3) * 11.901

M = 7.934

Part B

What the question is saying is that E/Eo = 10000

You don't have to figure out exact values.

M = 2/3 * log(10000)

M = 2/3 * 4

M = 8/3 or 2 2/3 or 2.66667

If you have choices, please list them.

Solve each inequality below. Represent the solutions on number lines. 7x − 2 &lt; 3 + 2x
LekaFEV [45]
Hi, I would be glad to help you here. 

<span>7x − 2 < 3 + 2x 

Move terms 

7x - 2x - 2 < 3 

Collect the like terms

(7x - 2x) = 5x (<3 + 2 stays the same) 

Calculate 

5x (<3 + 2 = 5) 

5x <5 

Divide both sides of the inequality by (5) giving you, 

x < 1 

So, finally in a total the correct answer here is (x < 1)
