Answer:
Step-by-step explanation:
the formula for density is:
where d is density, m is mass, and V is volume.
solving for m in the last equation:
so if we find the volume and multiply it by the density we will get the mass of the object.
The volume of a rectangular prism is given by:
where is length,
is width and
is height:
we substitute to find the volume:
since the density has units of we need the volume also in units of
, so we make the conversion using:
multiplying by 30:
and now we find the mass with the equation:
substituting d and V:
the nearest gram is:
The distance traveled by the Salmon is proportional to the duration spent
swimming.
A table of the distance traveled by the Atlantic Salmon is presented as follows;
Reasons:
The given parameter are;
The steady rate at which Atlantic Salmon swims = 2 miles in 3 minutes
Distance the Salmon swims, d ∝ Time taken, t
Therefore;
d = s·t
Where;
s = The constant of proportionality = The speed
Which gives;
The speed with which the Atlantic Salmon swims per minute is therefore;
The distance travelled, <em>d</em>, is given as follows;
A table showing the distance travelled by the fish with time is presented as follows;
