Answer:
53.33
Step-by-step explanation:
finding area of ΔPAM
using similar triangles
16 = 12x; x =
ΔPAM = 4/3 * 4 * 1/2 = 16/6 = 8/3
ΔPAL = 4 * 12 * 1/2 = 24
24 + 8/3 = 80/3 (using fraction form for now, will round later)
since there are two ΔPLM (ΔLMU has same area since they are congruent)
we can multiply 80/3 by 2
80/3 * 2 = 160/3 = 53.33
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.
