Just divide 1372.75 by 47.5 which is 28.9
Answer:
Work done
lb-ft
Step-by-step explanation:
The density of the chain in lb/ft is equal to
lb/ft
Total Work done is equal to the summation of work done up to the top of building.
We will use integration for this evaluation.
The mathematical relation is as follows

where "p" is the density
Substituting the given values, we get

Work done
lb-ft
X+y = 6
x-y = 2
Add both equations,
2x = 8
x = 4
Substitute it in equation 1,
4+y = 6
y = 6-4 = 2
In short, x = 4 & y = 2
Hope this helps!
<span>The question is requiring that you write the given word problem expression as a mathematical expression. Let the required number be x, then the difference of the number and 8 is x - 8. Then, five times the difference of a number and 8 is 5(x - 8) = 45</span>
