2.Mrs. Fernandez and Mrs. Bosiljevac invaded the biology lab! They find some bacterial cultures and decide to experiment. Mrs. Fernandez has 160 bacteria in a Petri dish, that double every 10 hours. Mrs. Bosiljevac has 10 bacteria, that quadruple every 5 hours. a) After how many hours will each culture have the same number of bacteria? Round to the nearest tenth.

b) How many bacteria will there be in each Petri dish at this time? Round your final answer.

4 hours 2560 bacteria

Step-by-step explanation:

If you do the multiplication side by side it equaizes itslef at 4 hours

nope

step-by-step explanation:

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
