Answer: There are 80 nickels, 120 dimes, and 300 quarters.
Step-by-step explanation:
Since for every 2 dimes there are 5 quarters, and for every 2 nickels there are 3 dimes, there can be 4 nickels, so there will be 6 dimes and 15 quarters. When you add all of them up it equals 25, so you take 500 divided by 25, and that equals 20, so you take the 4 nickels, 6 dimes, and 15 quarters times 20.
20 x 4 = 80
20 x 6 = 120
20 x 15 = 300
Hope this helps! :D

Step-by-step explanation:
Answer: the population of the culture 6 days after inoculation is 2313.
Step-by-step explanation:
The growth rate is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 + r)^ t
Where
y represents the population after t days.
t represents the number of days.
b represents the initial population.
r represents rate of growth.
From the information given,
b = 1000
r = 15% = 15/100 = 0.15
t = 6 days
Therefore
y = 1000(1 + 0.15)^6
y = 1000(1.15)^6
y = 2313
