If one dimension of a 3-dimensional shape is doubled, the volume increases by 21 = 2. If two dimensions of a 3-dimensional shape are doubled, the volume increases by 22 = 4. If all three dimensions of a 3-D shape are doubled, the volume increases by 23 = 8.
The answer is 5 minutes. Simply divide 60 by 12.
The similarity ratio, I believe, is 2:3.
Because the lengths are 6 and 9 (2:3), the widths are 8 and 12 (2:3), and the heights are 6 and 4 (2:3).
Answer:
The answers are in the question.
Step-by-step explanation:
The wording can be off-putting but the answers are mostly there for you. It says that when the wind was at the tail of the plane, the travel was hastened to 5 hours instead of six. Is the rate of speed with the wind in favor of the plane is r+21, then it stands to reason that traveling AGAINST the wind will cause the rate to drop to r-21. Taking the average of the two travel times (5 and 6 hours each), we get 5.5 hours. Since speed is distance divided by time, the speed of the plane in still air will be <em>d</em> / 5.5
Be sure to label the speed as mph.
Answer:
0
Step-by-step explanation:
it doesn't slope, it goes in a straight line, moving on the x-axis
