Answer:
6.5
Step-by-step explanation:
calculating for magnitude of quake in richer scale R
I = the quake's intensity = 106.5*I0
I0 = minimum intensity of earthquake
R = log(106.5*I0/I0)
R = log(106.5)
R = 6.5

Answer:
y = 2x or x = 1/2y or if you would like numerical values then x = 3, y = 6 and z=4
Step-by-step explanation:
x : y = 1 : 2
y : z = 3 : 2
If x : y = 1 : 2 then we know that 1y = 2x ∴ y = 2x or x = 1/2y
If y : z = 3 : 2 then we know that 3z = 2y ∴ z = 2/3y
The first one is undefined and the second one is 1/2
