Answer: a) 
b) 25165824000
Step-by-step explanation:
The exponential equation for growth is given by :-
, where a= initial value , b =multiplicative growth factor and t = time.
Given : A bacteria culture contains 1500 bacteria initially and doubles every hour.
i.e. a = 1500 and b= 2
Then, the function N that models the number of bacteria after t hours will be :
To find , the number of bacteria after 24 hours , we put t= 24 in above equation , we get
Hence, the number of bacteria after 24 hours is 25165824000.
The ratio of dressing to vegetable in its reduced form is determined by dividing the amount of dressing by the amount of vegetables. This will give us the answer of,
2 c / 4 lb
In its simplest form, we divide both the numerator and denominator by 2 and the final answer would be,
1 c / 2 lb
Answer:

Check work:
30 x 0.8333 = 24.999
30 + 24.999 = 54.999 or about 55
- 10x - 5 + 5x
- 10x + 5x - 5
