Answer:
option C
Step-by-step explanation:
and here we think of b=1 and a=-1
so we have
Volume = ( length x width x height ) / 3
For the pyramid in the picture, it would be ( s x s x h ) / 3
8 because all elements after nitrogen have not only two energy levels, they also find it easier to just get rid of electrons than to absorb electrons to get to 8 electrons.
2000 + 1500g ≤ 15000
1500g ≤ 15000 - 2000
1500g ≤ 13000
g ≤ 13000/1500
g ≤ 8 2/3
Therefore, the crane can safely lift a maximum of 8 2/3 cubic meters of gravel.
.75 or 75% or 6/8.
