Answer:

B) 100

Step-by-step explanation:

All 3 interior angles of a triangle add up to 180 so:

x + 25 + 55 = 180

x + 80 = 180

x = 180 - 80

x = 100

Find whether the no. 847,2160 are coprime or not

m_a_m_a [10]

First what you need to do is find the HCF of both numbers.
After you've done that if it is 1 then they are what we call co-prime.
Now, if they are other than 1 they are not co-prime.

The population P of rabbits on a small island grows at a rate that is jointly proportional to the size of the rabbit population

user100 [1]

Answer:

Option D:

$\frac{dP}{dt} = kP(2400 - P)$

Step-by-step explanation:

Differential equation:

For the population in function of the time, is:

$\frac{dP}{dt}$

The population P of rabbits on a small island grows at a rate that is jointly proportional to the size of the rabbit population and the difference between the rabbit population and the carrying capacity of the population

Carring capacity is 2400.

This means that the differential equation is kP(size of the population multiplied by the constant) multiplied by 2400 - P(difference between the population and the carrying capacity). So

$\frac{dP}{dt} = kP(2400 - P)$

So the answer is given by option D.
