Answer:
15
Step-by-step explanation:
-225/-15 = 15
A negative divided by a negative is a positive
225/15 = 15
Assuming that ' i ' is the old familiar square root of -1 ...
The square of 6i is -36 .
Of course, if ' i ' is something else, then (6i)² = 36 i² .
Answer:
The slope of the ramp is 1.
Step-by-step explanation:
See the diagram attached.
Here, AC = 15 ft. and ED = 5 ft. while AE = 10 ft.
Then, EC = (15 - 10) = 5 ft.
Now, considering the right triangle Δ EDC, if
is the inclination of the ramp, then ![\tan \theta = \frac{ED}{EC} = \frac{5}{5} = 1](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D%20%5Cfrac%7BED%7D%7BEC%7D%20%3D%20%5Cfrac%7B5%7D%7B5%7D%20%3D%201)
Hence,
Therefore, the slope of the ramp is 1. (Answer)
