Answer:
V = 300 cm³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the base and h the height )
Here A = 15 and h = 20 , then
V = 15 × 20 = 300 cm³
Answer:
18 feet
Step-by-step explanation:
Answer:
They will find 69 viruses in 8 hours.
Step-by-step explanation:
The number of viruses after t hours is given by the following equation:

In which V(0) is the initial number of viruses and r is the decay rate, as a decimal.
They start with 500 viruses
This means that 
Decay rate of 22% per hour.
This means that 
So



How many viruses will they find in 8 hours?
This is V(8).



Rounding to the nearest whole number
They will find 69 viruses in 8 hours.
