1. They would of been equal because half of 5 is 3 so he made it to the second vertex, therefore he could run either way back
2. No it is not a fair game because off the odds that each player has because their is only two white marbles in this game.
3. About 6.22 miles per amount of time

Answer:

1. 16 in

2. 30.72 m

Step-by-step explanation:

scale factor 1:12 where 1 is the model and 12 is the actual.

This means the actual length is 12 times larger than the model.

1. Take the actual length (16 ft) and divide by 12.

16 ft/12= 4/3 ft(1.333...)

The answer need to be in inches so you will multiply 4/3 ft* 12 to find the length in inches.

4/3*12/1= 48/3= 16 in

2. Take the model length (256 cm) and multiply by 12.

256* 12= 3072 cm

The answer needs to be in meters so you will divide 3072 cm by 100 to find the length in meters.

3072/ 100= 30.72 m

Assume that in the absence of immigration and emigration, the growth of a country's population P(t) satisfies dP/dt = kP for som

Morgarella [4.7K]

Answer:

A) Differential equation for population growth in case of individual immigration is:

$\frac{dP}{dt}=kP+r$

B) Differential equation for population growth in case of individual emigration is:

$\frac{dP}{dt}=kP-r$

Step-by-step explanation:

Population growth rate in the absence of immigration and emigration is given as:

$\frac{dP}{dt}=kP--(1)$

A) When individuals are allowed to immigrate:

Let r be the constant rate of individual immigration given that r >0.

Differential equation for population growth in this case is:

$\frac{dP}{dt}=kP+r$

B) In case of individual emigration:

Let r be the constant rate of individual emigration given that r >0.

Differential equation for population growth in this case is:

$\frac{dP}{dt}=kP-r$
