Let us assume the initial number of bacteria in the culture = x
After 1 hour,
The number of bacteria = 185x/100
= 1.85x
After 2 hours,
The number of bacteria = (185 * 1.85x)/100
= 3.42x
So
3.42x = 12500
x = 12500/3.42
= 3654.97
= 3655
From the above deduction, we can conclude that the initial number of bacteria in the culture is 3655
Answer:
b = 0
Step-by-step explanation:
Since,the equations y=3/4x+1 and y=1/2x+b intersect at (4,2)
So, plug x = 4 and y = 2 in equation y=1/2x+b, we find:
1) first pick red 5/9 blue 4/9
2) second pick when red has been picked red now becomes 4/8, blue stays 4/8
2) Second pick when blue has been picked blue now becomes 3/8, red stays 5/8
Mind you, you only need both different colours so:
first pick red 5/9 x sec pick blue 4/8 = 20/72
and first pick blue 4/9 x sec pick red 5/8 = 20/72
add both up 20/72 + 20/72 = 40/72 = 5/9
Answer:
22 miles
Step-by-step explanation: I know what you are talking about because I've had this assignment but it would be better to put a map or picture for people.
