The blood mass of a mammal is proportional to its body mass. A rhinoceros with body mass 3000 kilograms has blood mass of 150 ki

coldgirl [10]

Answer:

The equation which equates the two is M = $\frac{B}{20} = 0.05B$

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 = $\frac{150}{3000} = \frac{1}{20} = 0.05$

Therefore the equation which equates the two is M = $\frac{B}{20} = 0.05B$

A human with a body mass of 80 kilograms will have a blood mass of

= $\frac{80}{20} = 4 kilograms$

Answer:

1/2 mL/min

Step-by-step explanation:

$\dfrac{2\text{ mg}}{\text{min}}\div\left(\dfrac{2\text{ g}}{500\text{ mL}}\times\dfrac{1000\text{ mg}}{\text{g}}\right)=\dfrac{2\times500\text{ mL}}{2\times1000\text{ min}}=\boxed{\dfrac{1}{2}\text{ mL/min}}$

Additional comment

The units analysis tells you how to work this problem. In order to get from mg/min to mL/min, you need to multiply by a factor with units mL/mg. Those units are the inverse of the concentration in mg/mL, which is found from g/mL.

iren2701 [21]

Answer:

mean = 172.72cm and variance = 645.16

Step-by-step explanation:

1 inch = 2.54 centimetres

mean = 68 * 2.54 = 172.72 cm

standard deviation = 10 *2.54 = 25.4 cm

variance = square of standard deviation

variance = 25.4 * 25.4

variance = 645.16 cm
