umka2103 [35]

Answer:

4 trips

Step-by-step explanation:

Volume of tank = (20 * 30 * 40) = 24400 cm³

Volume of cubic container = (20 * 20 * 20) = 8000 cm³

Number of trips it would take :

Volume of tank / volume of container

24400 cm³ / 8000 cm³

= 3.05

Hence, it will take 4 trips

stellarik [79]
5x \geq 6y
The inequality above shows the relationship.

In this case, Kareem miles on the left have to be at least as much as Christine's on the right.
