Answer:
the density of copper is 90.03g/cm³
Step-by-step explanation:
This problem bothers on the density of a substance, this case for a copper material
Given data
Mass of copper m = 1355g
Volume of copper block v= l*b*h
10*5*3=150cm³
We know that the density
ρ= mass/volume
ρ= 1355/150
ρ= 90.03g/cm²
The density of a substance is defined as the mass of the substance per unit volume
To find the annual rate of interest, here's what we need to do:

In this case:
333/4500 x 100%
=37/500 x 100%
=7.4%
Therefore the answer is 7.4%.

Answer:
Of the 600 elephants that he observes in random places in the reserve, he counts
elephants with broken tusks.
Step-by-step explanation:
Let x denotes number of elephants having broken tusks out of 600 elephants.

So,
Of the 1 elephants that he observes in random places in the reserve, he counts
elephants with broken tusks.
Therefore,
Of the 600 elephants that he observes in random places in the reserve, he counts
