Answer:
1.5
Step-by-step explanation:
The magnitude, M, of an earthquake is defined to be
M = log l/s
where <em>I</em> is the intensity of the earthquake and <em>s</em> is the intensity of a “standard” earthquake.
If an earthquake that is 35 times more intense than a standard earthquake, then l/s = 35. Replacing it in the equation:
M = log 35 = 1.5
I'm not sure if this is a trick question but, if I was to assume my answer would be 1136. If it is a trick question, if the odometer only registers 6 miles then it'd either be 189.5m or 6 miles because it only registers 6 miles so it wouldn't change.
Answer:
a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).
Step-by-step explanation:
The second equation needs to be ...
5x +5y = 50
because the wording "short of $18" means that the actual cost of that purchase would be $18 more than the $32 that Harry had. 18+32 = 50.
The only answer choice that shows this as the second equation is choice A.

In fact, the solution to the system of equations is (8, 2), as can be seen in the graph below.
It is a tool as it represents the language of patterns.
It is also a means of working with abstract notions and then applying them, which frequently leads to the formation of generalisations and insights outside of the original context.
