a bug population doubles every 5 days. If you start with 6 bugs, how many bugs will there be in 35 days
Shtirlitz [24]

Answer:

768 bugs

Step-by-step explanation:

You can rewrite this problem as a function as time where the bug population is f(x), and x is the number of days since the start.

f(x)=6*2^(x/5)

Here, the 6 represents the number of bugs that you start with, the two shows that they double every day, and the /5 shows that they double every 5 days.

By plugging in 35, you get 6*2^7, which is 768.

Hey factory can produce fifth refrigerators in eight hours how many hours would it take to produce 1250 refrigerators
jarptica [38.1K]

Hey, I'm assuming you mean five refrigerators every eight hours. So . . .

1250 divide by 5. Which gives you 250.

Then take that 250 and multiply it by 8, and you have 2000.

So it would take 2000 hrs for a factory, that can produce 5 refrigerators every eight hours to, produce 1250 refrigerators.
