Second one is 1
Answer:
Step-by-step explanation:
Formula
Volume = L * w * h
Givens
L = 7 feet
w = 4 feet
h = 5 feet
Solution
V = L * w * h Substitute values into the formula
V = 7 * 4 * 5
V = 140 cubic feet.
Answer
140 ft^3
Answer:
The initial population was 2810
The bacterial population after 5 hours will be 92335548
Step-by-step explanation:
The bacterial population growth formula is:

where P is the population after time t,
is the starting population, i.e. when t = 0, r is the rate of growth in % and t is time in hours
Data: The doubling period of a bacterial population is 20 minutes (1/3 hour). Replacing this information in the formula we get:





Data: At time t = 100 minutes (5/3 hours), the bacterial population was 90000. Replacing this information in the formula we get:



Data: the initial population got above and t = 5 hours. Replacing this information in the formula we get:
