Question

rabbits population can double every 30 days if there are 10 rabbits on a farm how many rabbits will be on the farm after 120 days

Answer 1

Answer:

Step-by-step explanation:

= 10(1+1)^4 the final answer is 160

How I got 4 is you divide 30\ 120 =4

Answer 2

After 120 days there will be 160 rabbits on the farm.

What is equation?

"It is a mathematical statement which consists of equal symbol between two algebraic expressions."

For given question,

Rabbits population can double every 30 days.

Initially there are 10 rabbits in a farm.

So, after 30 days there would be 10 × 2 = 20 rabbits.

After next 30 days, there would be

20 × 2

= 10 × 4

= 10 × 2²

= 40 rabbits.

Let t be the number of days and x be the number of rabbits.

So, we have an equation:

$x=10\times2^{\frac{t}{30} }$

No, we find the number of rabbits after 120 days.

t = 120

So, the equation becomes,

$x=10\times2^{\frac{t}{30} }\\\\x=10\times2^{\frac{120}{30} }\\\\x=10\times2^{4}\\\\x=10\times 16\\\\x=160$

Therefore, after 120 days there will be 160 rabbits on the farm.
