duval county landscaping uses two different sized trucks to deliver mulch.
The first truck can transport x cubic yards of mulch, and the second can transport y cubic yards of mulch.
The first truck makes 12 tripes to a job site.
⇒Number of cubic yards first truck makes = 12x
It is also given that:
The second makes 14 trips.

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
