Answer:
120 lbs
Step-by-step explanation:
Work = force * distance
1800 ft-lb = force * 15 ft
force = 1800 ft-lb / 15 ft
=1800/15 ft-lb/ft
=120lbs

Answer:
Total weight is 150 kg
Step-by-step explanation:
Firstly, we need the weight of the diagonal
To get this, we shall use the Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides
The diagonals stand for the hypotenuse
Thus, we have that;
d^2 = 5^2 + 12^2
d^2 = 25 + 144
d^2 = 169
d^2 = 13^2
d = 13
The 6 sides technically includes the whole rectangle sides, then the two diagonals
The total length here is;
2(5 + 12 + 13) = 60 meters
Steel weight is 2.5 kg per meter
Weight of 60 m will be ;
60 * 2.5 = 150 kg
511 divided by 7 is the unit rate. So a is how you get it but d is the answer
