Answer:
The length of the porch is 18ft
Explanation:
When we do a scale drawing, each unit in the scale drawing represents some other unit in the actual thing that is being drawn, defined by a factor of scale k.
In this case, we know that in the scale drawing the porch is 8 inches wide, and we know that the actual width of the porch is 12 ft.
Then for a factor of scale k we have:
8 in = k*12 ft
(8in/12 ft) = k.
And this scale factor is the same for every measure of the drawing.
Then if the length of the actual porch is L, the length in the scale drawing will be k*L
And we know that the length in the scale drawing is 12 inches, then:
12 in = k*L
12 in = (8in/12 ft)*L
12 in*(12ft/8in) = L = 18ft
The length of the porch is 18ft
Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls
Alfred Wegener developed the idea of continental drift that was corroborated by the later theory of plate tectonics. It was important that he had solid evidence for his theory because of the critics who disagreed. So not only did he use the jig-saw fit of continents like South America and Africa but also their geology which matched between these two and having similar fossils.
