Aculture started with 1,000 bacteria. after 2 hours, it grew to 1,100 bacteria. predict how many bacteria will be present after 9 hours.

450 Bacteria

Step-by-step explanation:

First we need to consider the amount of bacteria that grew after two hours. Since 100 bacteria grew after 2 hours, we need to find how much bacteria grows per hour.

We can find that by dividing 100 by 2

100/2 = 50 Bacteria per hour

Now that we know how much bacteria grows per hour, we can then multiply that amount to the amount of hours asked in the problem.

9 hours x 50 Bacteria = 450 Bacteria in 9 hours.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
