A culture started with 1,000 bacteria. After 6
hours, it grew to 1,300 bacteria. Predict how
many bacteria will be present after 10 hours.
Round your answer to the nearest whole
number.
P = Aekt

1,500 bacteria.

Step-by-step explanation:

I don't know what P=Aekt means but I understand the rest:

Hour 0: 1,000 bacteria

Hour 6: 1,300 bacteria

We can conclude from this evidence that it takes 6 hours to grow 300 new bacteria.

Let's use a ratio

new bacteria : hours

      300          :     6

        50          :      1

       500         :     10

So we get 500 new bacteria after 10 hours. Using our original population of 1,000 and our new added members, we get 1,500 bacteria at Hour 10.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
