This means 5 meters/20 steps = x/1,000 steps. 20 times 50 is 1,000, so 5 times 50 is 250 meters. 5/20 can be also reduced to 1/4 = x/1000. Use cross products rule to get 4x = 1,000. Divided both sides by 4 to get x = 250 meters.
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

Answer:
A. 4
Step-by-step explanation:
Constant of proportionality (k) = y/x
We can use the coordinates of any point on the line to find k.
Let's use (2, 8)
Constant of proportionality (k) = 8/2
Constant of proportionality (k) = 4
X+40=4x+10
4x-x=40-10
3x=30
x=10 miles
<em><u>Answer: 10 miles</u></em>
