Suppose a single bacterium is placed in a bottle at 11:00am. It grows and at 11:01 divides into two bacteria. These two bacteria each grow and at 11:02 divide into four bacteria. Which grow and at 11:03 divide into eight bacteria, and so on. Now, suppose the bacteria continue to double every minute until the bottle is full at 12:00.

a. How many bacteria are in the bottle at 11:53?

b. What fraction of the bottle is full at that time?

Number of bacteria at 11:53 for 53 min =   = 9.007199 ×  

fraction that is full =

Step-by-step explanation:

solution

Number of bacteria is express as here

Number of bacteria =    ............1

so

bacteria at 1 min , 2 min and 3 min are

Number of bacteria at 1 min = = 2

Number of bacteria at 3 min = = 4

Number of bacteria at 3 min =  = 8

and

as that Number of bacteria at 11:53 is for 53 min is

Number of bacteria at 11:53 for 53 min =   = 9.007199 ×  

and

bottle is full at 12:00

so Number of bacteria at 12:00 for 60 min =  

so fraction that is full =

fraction that is full =

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
