B. is your answer
Step-by-step explanation:
V=whl=7·6.5·7=318.5
Answer:
see the explanation
Step-by-step explanation:
we now that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
In this problem we have

This is the equation of the line in slope intercept form
where

The given equation not represent a proportional relationship, because the line not pass through the origin
In a proportional relationship the value of b (y-intercept) is equal to zero
Answer:
(1 point)
No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.

Answer:</h2>
<em>The course costs, approximately, </em><u><em>$0.16 per hour</em></u><em>.</em>
<h2>
Step-by-step explanation:</h2>
<h3>1. Convert the 10 weeks to hours.</h3>
10 weeks * 7= 70 days
70 days * 24= 1680 hours
<h3>2. Calculate cost/hour.</h3>
<em>Establish a rule of 3.</em>
<em>1680 hours -----> $275</em>
<em>1 hour -----> x</em>
<em>x= (1 hour * $275) / 1680 hours</em>
<em>x= 0.1636904762 ---> Round to the nearest cent.</em>
<em>x= 0.16 ---> Final result.</em>

As the question says when there's no overtime, you only care about normal working hours.
