I'm studying a new bacteria that doubles in numbers every 25 minutes. if i start with 50 bacteria, how long until i have 5 million of them

415.63 minutes

Step-by-step explanation:

Growth can be represented by the equation . We can find the rate at which it grows by using t=25 minutes and or double the amount at that time. The first step we always take is to divide by A.

To solve for r, we will take the natural log of both sides and use log rules to isolate r.

We know so we were able to cancel it out and divide both sides by 25.

We solve with a calculator

We change 0.0277 into a percent by multiplying by 100 to get 2.77% as the rate.

The equation is .

We repeat the step above substituting A=5,000,000, =50, and r=0.02777. Then solve for t.

t=415.63 minutes

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

26
