Volume=length*height*width
528=12*5.5*w
divide both sides by 12
44=5.5w
divide both sides by 5.5
8=w
width is 8 inches
For this case we have that by definition, the slope of a line is given by:

Where:
and
are two points through which the line passes
According to the statement we have:

Substituting we have:

Thus, the slope of the line is:

Answer:

Answers:
1A. You see, every amount of T shirts costs 5.5 times more than it's amount. So if "n" is the number of shirts and "C" is what it costs, then the equation must be C=5.5n.
1B. Idon't know how to graph it here sorry.
1C. You have to look back to the equation. It has our coefficient (5.5n) on one side and C on the other,so the answer is just 5.5n. Now the questions says 120 shirts so (120)5.5 equals 660.
1D. I just did
Step-by-step explanation:

0.2m^3 = 0.0000002 cm^3
Fern's estimate is not correct because he rounded 548 wrong, it would be rounded to 550 instead since the number 8 is closer to 10. So the correct answer would be 420.
