Answer:
10¹⁸ ergs
Step-by-step explanation:
From the question,
Using the expression
M = 
log(E/10¹³)................. Equation 1
Where M = Richter magnitude of earth quake, E = Energy released in ergs.
Given: M = 4.0
Substitute into equation 1 amd solve for E
4 = log(E/10¹³)
Log(E/10¹³) = (4×5)/4
Log(E/10¹³) = 5
E/10¹³ = 10⁵
E = 10⁵×10¹³
E = 10⁵⁺¹³
E = 10¹⁸ ergs
Answer:
$110
Step-by-step explanation:
The <u>Midpoint</u> of a segment divides the segment into two segments of equal length.
In order to solve it you have to get x by itself.
1. Simplify. 1/4 + 1/2 + x is also the same as 3/4 + x. So you have 3/4 + x = -3/4.
2. Then you subtract 3/4 on both sides to get x by itself. x = -3/4 - 3/4
3. Simplify. x = -1 1/2 or -1.5 depending on whether you need the answer in a fraction or a decimal.
