Suppose a population of 250 crickets doubles in size every 6 months. How many crickets will there be after 2 years?

The number of crickets after 2 years is 4000.

Step-by-step explanation:

Given,

Number of crickets = 250

It doubles in number in every 6 months.

To find the number of crickets after 2 years.

Now,

Presently, number of crickets = 250

In 1st 6 months number of crickets = 250×2 = 500

In 2nd 6 months ( after 1 year) number of crickets = 500×2 = 1000

In 3rd 6 months number of crickets = 1000×2 = 2000

In last 6 months number of crickets = 2000×2 = 4000

Hence,

The number of crickets after 2 years = 4000

4000 crickets

Step-by-step explanation:

Step 1: convert 2 years into months, by noting that 12 months = 1 year

2 years = 12 x 2

2 years = 24 months

From the information given, if 250 crickets doubles every 6 months, Where we have 24/6 cycles of 6 months in 2 years = 4 cycles

250 x 2 = cycle 1 = 500

500 x 2= cycle 2 = 1000

1000 x 2 = cycle 3 = 2000

2000 x 2= cycle 4 = 4000

Therefore, in two years, number of crickets will be 4000.

answer:      

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
