Answer:
627200LJ
Step-by-step explanation:
Height of box=5 m
Side of square base=4 m
Volume of rectangular box=
Using the formula
Volume of rectangular box=
Density of material=
We know that

Using the formula
Mass of rectangular box=
Gravity=
Weight of rectangular box,F=
Let L be the vertical distance traveled by box
Total work done =
Therefore,total work done against gravity =
=627200 L J
Hence, the box requires work against gravity=627200LJ
Answer:
Commision rate 13%
Explanation:
The commission rate is equal to the commission as a percent of sells.
Now in our case,
sells = $2700
commission = $351
Therefore, the commission rate is equal to

(18 + 12q) = 6(2q - 7) Use the Distributive Property on both sides
6 + 4q = 12q - 42 Subtract 12q from both sides
6 - 8q = -42 Subtract 6 from both sides
-8q = -48 Divide both sides by -8
q = 6
