Answer:
3200 ft-lb
Step-by-step explanation:
To answer this question, we need to find the force applied by the rope on the bucket at time 
At 
After seconds, the weight of the bucket is 
Since the acceleration of the bucket is the force on the bucket by the rope is equal to the weight of the bucket.
If the upward direction is positive, the displacement after seconds is 
Since the well is 80 ft deep, the time to pull out the bucket is 
We are now ready to calculate the work done by the rope on the bucket.
Since the displacement and the force are in the same direction, we can write
Use and 
![=\left[63 t-0.2 t^{2}\right]_{0}^{36}](https://tex.z-dn.net/?f=%3D%5Cleft%5B63%20t-0.2%20t%5E%7B2%7D%5Cright%5D_%7B0%7D%5E%7B36%7D)
1/6+3/7 least common denominator is 42 so...
7/42+18/42= 25/42
Answer:
The second one is (3 x 3 x 3 x 3) x (3 x 3)
Step-by-step explanation:
Answer:
41 people
Step-by-step explanation:
Clinton hosted an end-of-year party. He expected 5 guests, but 8 times as many showed up. How many people attended?
The amount of guest that showed up can be calculated as:
5 guest × 8 times the number of guests
= 40 guests
The number rod people that attended the end of the year party = 40 guest + Clinton
= 41 people
3 more than x
this means that whatever x is, 3 more than that
3 more means 3+ so
3+x is the answer
