Answer:
The equation which equates the two is M =
A human with a body mass of 80 kilograms will have a blood mass of 4 kilograms.
Step-by-step explanation:
It is said that the blood mass is proportional to the body mass.
We can say that the blood mass of a mammal is M, and that the body mass of a mammal is B.
Since the two are proportional we can write
M ∝ B , or M = kB where k is the constant of proportionality.
Using the given values for a rhinoceros we can write
150 = k × 3000
Therefore k =
Therefore the equation which equates the two is M =
A human with a body mass of 80 kilograms will have a blood mass of
