Answer:
2480 new movies
Step-by-step explanation:
1) First you need to find out how much money the 400 older movies made.
2) Next subtract that amount from the amount of revenue that the wants.
3) Divide the amount of leftover money by the amount that a new movie costs to rent

Answer:
Safe Load is 127 lb.
Step-by-step explanation:
Given:
Load (L) = 1090 lb.
width(w) = 6 in.
depth (d) = 9 in.
length (l) = 12 ft.
Since all other units are in inches and unit of length is in feet, So we will convert foot into inches we get;
1 feet = 12 inches
12 feet =
Hence length(l)= 144 in.
Now also Given
Load varies directly with width and square of depth and inversely with length.
Hence we can say that;
L∝
Hence where k is constant.
Now Substituting the given values we will find the value of k we get;
Also Given:
width(w) = 5 in.
depth(d) = 4 in.
length(l) = 17 ft.
1 ft. = 12 in.
17 ft =
Hence length(l) = 204 in.
k = 322.96
We need to find the load beam(L);
Substituting new values we get;
Rounding the load in nearest pound we get;
Load beam(L) = 127 lb
Hence Safe Load is 127 lb.
