Answer:
Step-by-step explanation:
let x = apples and y = bananas
x + y = 20
.5x + .75y = 11.5
solving for x
x = 20 - y
.5(20 - y) + .75y = 11.5
10 - .5y + .75y = 11.5
-.5y + .75y = 11.5 - 10
.25y = 1.5
y = 1.5 / .25
y=6
therefore x=14
14 apples and 6 bananas
Answer:
95 hours .
Step-by-step explanation:
Equation: 
Where G is the generation time .
t is is the time period of the population increase.
a is the number of bacteria at the beginning of the time period.
P is the number of bacteria at the end of the time period.
We are supposed to find If the generation time for the bacteria is 4.5 hours, how long will it take 4 of these bacteria to multiply into a colony of 7525 bacteria.
So, G = 4.5 hours.
a = 4
p = 7525
Substitute the values in the given equation.


Hence it took 95 hours for 4 of these bacteria to multiply into a colony of 7525 bacteria.
