Answer:
It's elevation at the surface is 0, and the elevation twenty feet below is -20.
Step-by-step explanation:
The surface level is 0, and diving 20 feet under means 0 - 20, which is negative 20, or -20.
10+10=20 = length
20 + 18 = 38 width = 18 or 9 on each side
10 x 9 = 90
Answer 90
Answer:
-9/11
Step-by-step explanation:
The slope of the line is given by
m = (y2-y1)/(x2-x1)
= (9-0)/(-3-8)
= 9/-11
= -9/11
Answer:
6 : 11
Step-by-step explanation:
the ratio 6 : 11 applies to all linear measure in the similar polygons
Both side lengths and perimeter are linear, hence
ratio of both is 6 : 11
