Answer:B
Step-by-step explanation:
Divide the two numbers
Answer:
(a) the initial count of bacteria
(b) the growth factor (per hour)
(c) the initial count in the second study
(d) the difference in initial counts between the two studies
Step-by-step explanation:
(a) 1200 is b1(0), the initial count of bacteria.
__
(b) 1.8 is the growth factor per hour, the factor that multiplies the previous hour's count to get this hour's count.
__
(c) Assuming b2(t) = 1000(1.8)^t, the value 1000 is the initial count of bacteria in the second study, b2(0).
__
(d) The difference between 1200 and 1000 means the first study started with 200 more bacteria than the second study did
If there is 8 sq. miles, and you want to know how many 1/6 can you get out of it, you would divide them.
8 divided by 1/6
8 x 6/1 (you have to multiply by the reciprical because you can not divide fractions)
8 x 6= 48 wind turbines can be built.
Answer:
2x + 9 = 21
----------------
1. subtract 9 from both sides
2x = 12
2. divide 12 by 2
x = 6
