Step-by-step explanation:
Rate of growth equals 420/100 = 4.2 times per hour
So after t=three hours,
size of culture = 100*(4.2)^t = 100*4.2^3=7408.8 bacteria,
round to nearest unit 7409 bacteria after three hours (after initial size of 100).
Step-by-step explanation:
3y + x = 12
When y = 3, we have 3(3) + x = 12.
=> 9 + x = 12, x = 3.
Answer:
27
Step-by-step explanation:
3*3*3=27
The suit case originally weights 48 kg
.75x = 36x = 33/ .75 = 48
Answer:
84000 people
Step-by-step explanation:
So next 5 year wil be 56000 + 50%
56000 = 100%
50% = 56000 / 2
50% = 28000
56000 + 28000 = 84000
