Answer:
The number of Bactria after 5.8 hours is 12242.
Step-by-step explanation:
The number of bacteria in a refrigerated food product is given by
where, T is the temperature of the food.
When the food is removed from the refrigerator, then the temperature is given by
We need to find the composite function N(T(t)).
where N(T(t)) is the number of bacteria after t hours.
Substitute t=5.8 in the above function.
Therefore, the number of Bactria after 5.8 hours is 12242.
The answer is C. C=-1
-4(-1)= 4 a negative times a negative is positive
4+5 is 9
You have to do 225 plus 125 divided by 2 times 100 and that is your percent
Answer:
x = number of bicycles = 35
y = number of cars = 55
Step-by-step explanation:
Let
x = number of bicycles
y = number of cars
x + y = 80 (1)
2x + 4y = 270 (2)
From (1)
x = 80 - y
Substitute x = 80 - y into (2)
2x + 4y = 270 (2)
2(80 - y) + 4y = 270
160 - 2y + 4y = 270
- 2y + 4y = 270 - 160
2y = 110
y = 110/2
y = 55
Substitute y = 55 into (1)
x + y = 80 (1)
x + 55 = 80
x = 80 - 55
x = 35
x = number of bicycles = 35
y = number of cars = 55
