Answer:
W = 15900 ft.lb
Step-by-step explanation:
From the given information.
Consider y to be the distance from the ground towards the bucket of the cement.
At height y, suppose the bucket is lifted by Δy.
Then, the workdone can be = 500Δy + 0.5(75 - y) Δy
where;
The bucket of the cement = 500Δy
The remaining of the rope = 0.5(75 - y) Δy
However; the workdone (W) can be calculated as:
W = 15000 + 0.5 ( 2250 - 450)
W = 15000 + 900
W = 15900 ft.lb

Answer:
1. C -> Marty's with a slope of 1/3
2.C -> 2x + 5y = -15
3. C -> y = 1/4x + 2
4. A -> x - 4y = 8
5. D -> 5
Yes for all integers and no for operations which include
subtraction and division.
It is widely used in many equations, either to group or to
simplify equations. Associative Property of basic operations is a property of
means to cluster or set some numbers into simpler equations. It is only applicable
for operations that include adding and multiplying. Take note of the arrangement
for these set of equations. For example, 1a + 3xy + 4xy = 1a + (3 + 4)xy.
