Answer:
The first graph shows a slope of 3.
Step-by-step explanation:
If the slope is 3, it's actually 3/1 because of rise/run. So you find any point on the graph that's directly between two lines, like (-1,-5). Since the line is positive, you would go right one and up three. Then you see if that point is directly between two lines. The next point is (0, -2). If you did the same on the second graph, it wouldn't match up.
About 47 inches you have to multiply 15 by pi
There is a formula for this:
Total Time = (worker1 * worker2) / (worker1 + worker2)
(3 * 8) / (3 + 8)
24 / 11 =
2.1818181818 hours
