-1/2 because slope is the rise over the run. If you count on the grid from one point on the line to another you go up one and 2 to the left meaning the slope is 1/2, buttttt when the line decreases going to the right, it has a negative slope so you just add a - sign in front

Write 3.242424... as a mixed number.
victus00 [196]

Answer:

3\frac{8}{33}

Step-by-step explanation:

3.242424.....

This number can be written as 3  + 0.242424....

We convert the decimal part into fraction

Let x= 0.242424......

Multiply both sides by 100

100x = 24.2424....

     x=     0.2424.....

------------------------------------- (subtract  it)

99x = 24

Divide both sides by 99

So x= 24/ 99

simplify the fraction

\frac{24}{99} =\frac{8}{33}

3.242424... can be written as 3  + 0.242424....

Replace the fraction for decimal

So final answer is 3\frac{8}{33}

Bacillus cereus is a soil-dwelling bacterium that sometimes causes food poisoning. Each cell divides to form two new cells every
Readme [11.4K]

Answer: There are 6400 bacteria that will be present after 3 hours.

Step-by-step explanation:

Since we have given that

Initial number of bacterial cells = 100

Each cell divides to form two new cells every 30 minutes.

Number of hours = 3 hrs

Number of minutes in 3 hours = 3\times 60 = 180 minutes

Number of 30 minutes in 3 hours = \dfrac{180}{30}=6

So, our equation becomes,

P(x)=ab^x\\\\P(3)=100(2)^6\\\\P(3)=6400

Hence, there are 6400 bacteria that will be present after 3 hours.
