Answer:
I think its 2 hours 30 minutes
Step-by-step explanation:
B. 5.5×(7.5×6.4) =(5.5×7.5)×6.4
After 3 hours each strain will have been depleted completely to 0 cells. Given the numbers 6000 and 2000, you will find that a decrease of 33.33333% for strain A and a 50% decrease for strain B will not intercept on the same hour. Strain B will have been depleted for an hour at the time that strain A is gone.
Answer:
The answer is "(4, -5)".

In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is 
Putting the value in x = 5 and y = 4 then:
Answer:
B
Step-by-step explanation:
Note:
1 gal = 4 quarts
1 pint = 0.5 quart
Re-writing all the choices in dollars and quarts and calculating how much each quart costs
A) $1 per 1 quart
B) $2 per gallon = $2 per 4 quarts = $2 ÷ 4 quarts = $0.50 per quart
C) $1.50 per 2 quarts = $1.50 ÷ 2 quarts = $0.75 per quart
D) $0.50 per 1 pint = $0.50 per 0.5 quart = $0.50 ÷ 0.5 quart = $1 per quart
If you compare all of the above, it is clear that answer B ($0.50 per quart) is the cheapest rate and hence the best deal.
