Answer:
Marco- 10 is the starting value of the population. 2 is the growth rate of "double each day" with d as an exponent.
Isabella- 1 is the starting population. 1+0.2=1.2 is the rate at which it grows each day.
Step-by-step explanation:
Marco's equation should be since the bacteria double each day. 10 is the starting value of the population. 2 is the growth rate of "double each day" with d as an exponent. This will double each day because:
Day 1 is
Day 2 is
Day 3 is
Day 4 is
You'll notice the value doubles each day.
Isabella has a different equation because her population increases by a percentage. We use the simple interest formula to calculate the bacteria's daily increase or interest.
1(1+0.2)d
1 is the starting population.
1+0.2=1.2 is the rate at which it grows each day.

Answer:
yes
Step-by-step explanation:
First we should find a GCF for the number of boys and girls.
The gcf for the two would be 4.
Divide.
20/4 = 5
28/4= 7
therefore the ratio for boys to girls would be 5 to 7
