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
Okay. So, to find the percent change, we have to do change/original. In this case, it would be 12/15, because 15 and 27 are apart by 12. 12/15 is 0.8. Multiply that by 100 and you get 80. There was an 80% markup of the chair sold to the antique dealer.
Answer:
The number of words per page.
Step-by-step explanation:
We're given the time per page. The book could have 10 words or it could have 1,000 words. We wouldn't know until given that information.
Answer:
slope = -2
Step-by-step explanation:
You can solve this several different ways, but I’ll show you using rise over run. As you can see, you need to rise 4 to get to the point (0,4) from the point (2,0). Then, you go two units to the left getting 4 as the rise and -2 as the run. Now you divide 4 by -2 to get -2 as the slope.
Hope that helps and please let me know if you need more help!
Have an amazing day!!
I don’t see a point so how am I supposed to answer
