Keisha, a scheduler at Mangel-Wurzel Transport, gets a call from a regular customer needing to move 70.3 m of rock and soil, which Keisha knows from previous experience has an average density of 880 kg/m". Keisha has available a dump truck with a capacity of 9 m and a maximum safe load of 5300 kg. Calculate the number of trips the dump truck will have to make to haul the customer's load away.

"12 trips" is the correct answer.

Explanation:

Given:

Density,

= 880 kg/m

Volume,

= 70.3 m³

Safe load,

= 5300 kg

Now,

The total mass of dump will be:

=

=

=

By going through the safe mode, the number of trips will be:

=

=

=

hence,

By going through the volume, the number of trips will be:

=

=

Thus the truck needs to make 11.57 trips i.e., 12 trips.

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

i have no clue hope you find the answer
