Answer:
(d)
Step-by-step explanation:
Multiple your numbers out first. This always makes it less hectic to look at. Multiply both sides by x to move the x to the right side. Then divide both sides by ((0.4365)(87.9)). You should get 10.
Answer:81/4
Step-by-step explanation:
Answer:
R=10,244 Lb
Step-by-step explanation:
In order to solve this problem, we can start by drawing the situation. (See attached picture).
We can look at the forces applied by the trucks as vectors, so in this case, in order to find the resultant force, we can add the two vectors. You can do so by drawing one force after the other and join the start of the first force with the end of the second force to form a triangle. The missing side will be the resultant force. In that triangle I drew there, the inner angle will be found by subtracting 180°-110°=70°
In this case we can find the resultant force by using the law of cosines:

so we can use the data given by the problem:

so we can solve this for R, so we get:

now we can substitute:

which yields:
R=10,244Lb
Answer:
june 21 or 22
Step-by-step explanation:
When the axis is tilted toward the sun, the corresponding hemisphere experiences summer. The maximum tilt occurs on the summer solstice. In the northern hemisphere, that is June 21 or 22.
