Answer:
<h2>1</h2>
Step-by-step explanation:
Magnitude 
of an earthquake is defined as 
. Here 
is the Intensity of the earthquake and 
is the intensity of standard earthquake.
We have an earthquake that is 10 times more intense than a standard earthquake. Let us denote the intensity of the earthquake as .
10 times more intense than standard earthquake ⇒ 
Magnitude of the earthquake = 
∴ Magnitude of the earthquake is 1.
Answer:
Let's say that x is sam's age and y is Amy's age
x=y-4
and five years ago:
x-5=(y-5)/2
y-4-5=(y-5)/2
2y-18=y-5
y=13
x=9
then:
sam's age is 9 and Amy's age is 13

Step-by-step explanation:
next time you answer someone's question with a bunch of random letters just to get the points don't. It rude especially sense you have questions you want answered. Now I could be nice and help you because I know how to solve this and you obviously don't, but I'm giving you the same curtesy as you did me and writing a bunch of gibberish.
-2x + xy = 30.....when y = 8
-2x + 8x = 30
6x = 30
x = 30/6
x = 5 <==
Evaluate the power 3600-6.3 x 100, then your gonna want to multiply the numbers 3600-630 , once you subtract the numbers your answer will be 2970
