Answer: 9V</h3>
=============================================================
Reason:
The volume expression of a cone with radius r and height h is
Let's plug in the given height h = 12 and we'd get
This is the volume of the first cone. We're told the first cone has a volume of V, so we can say 
We can't find the actual numeric volume because we don't know what value replaces r. So we leave it as is.
The second cone has the same height (h = 12) but the radius is now 3 times in size. Instead of r, we use 3r
Replace every copy of r with 3r. Then simplify
The radius tripled which results in a volume that's 9 times bigger.
Answer:
The parallel line has slope 
The perpendicular line has slope 
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope.
Parallel lines:
Parallel lines have the same slope.
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
In this question:
We have the following line:
Placing it in the general format
So this line has slope
Parallel line:
Same slope, so the parallel line has slope
Perpendicular line:
Multiplication of the slopes is -1. So
The perpendicular line has slope
Okay, here we have this:
Considering the provided information, we are going to find the x- and y- intercepts and explain its meaning. So we obtain the following:
Since the x-intercept is the point where the Graph intersects the x-axis (y=0) and the y-intercept is the point where the Graph intersects the y-axis (x=0), we have that:
x-intercept=(300, 0)
y-intercept=(0, 16)
Since the y-axis represents the number of gallons, and the x-axis time, then the y-intercept indicates that when filling the tank it was left with 16 gallons, and the x-intercept indicates that when emptying the tank had traveled 300 miles.
Jack would be 13 and jimmy would be 5 from what i found
He starts out with 150.
150+ 50+200
200-20=180
180+75= 255
255-100= 155
After all the transactions, he had $155.
