Answer:
3750 J
Step-by-step explanation:
We are given that
Total number of cartons=10
Height of loading dock from the side walk=1.5 m
Length of ramp=10 m
Mass of each carton=25 kg
We have to find the work done by the delivery man on the cartons to move them to the loading dock.
Work done=
Where M=Total mass of object
h=Height of object above the ground
g=Acceleration due to gravity=
Total mass of cartons=M=
h=1.5 m
Substitute the values then, we get
Work done=
J
Hence, the total work done by the deliverman on the cartons to move them to the loading dock=3750J
X=one type that cost 9
y=one type that cost 8
total books=type1+type2
total books=13
x+y=13
the total cost=cost of each added together
cost of each=number of books times cost per book
total cost=108
9x+8y=108
we have
x+y=13
9x+8y=108
solve for x and y
multiply first equation by -8 and add to first equation
-8x-8y=-104
<u>9x+8y=108 +</u>
x+0y=4
x=4
subsitute
x+y=13
4+y=13
minus 4
y=9
4 of the $9
9 of the $8
thats how to solve
