There will be 13,122 micro-organisms present at noon the next day

The number of hours between noon today and noon tomorrow is 24 hours.

The micro-organisms triple every 3 hours. The first thing you need to do therefore, is to find the <u>number of 3 hour intervals in 24 hours. </u>

= 24 hours / 3

= 8 three hour intervals

The micro-organisms started with 2 and will triple every 3 hour intervals.

There are 8 three hour intervals so the number of micro-organisms at noon the next day is:

<em>= Beginning number of micro-organisms x 3 ^ number of three hour intervals </em>

= 2 x 3⁸

= 13,122 microorganisms

In conclusion, there will be 13,122 micro-organisms.

Algebra problem help
True [87]
To solve this problem you must apply the proccedure below:

 1. You have that one canned juice drink is 20% orange juice and another is 5% orange juice.

 2. You must make a system of equation, as below:

 x+y=15  (i)
 0.20x+0.05y=0.15x15   (ii)

 3. Now, you must find the value of x (the liters of the first canned needed) and y (the liters of the other canned needed):

 x+y=15  (i)
 x=15-y

 0.20x+0.05y=0.15x15   (ii)
 0.20(15-y)+0.05y=2.25
 y=5 liters

 x+y=15  (i)
 x=15-5
 x=10 liters

 4. Therefore, the asnwer is:

 10 liters of the canned juice drink that is 20% orange juice and 5 liters of the other canned juice drink that is 5% orange juice.

sheldon bought 4 1/2 kg of plant food. he uses 1 2/3 kg on his strawberry plant and used 1/4 kg for his tomato plant. how many k
fenix001 [56]

Answer:

Sheldon have left 2\frac{7}{12}\ kg of food.

Step-by-step explanation:

Quantity of food = 4\frac{1}{2}=\frac{9}{2} kg

Quantity used on strawberry plant = 1\frac{2}{3} = \frac{5}{3}\ kg

Quantity used on tomato plant = \frac{1}{4}\ kg

Food left = Total - used on strawberry - used on tomato

Food left = \frac{9}{2}-\frac{5}{3}-\frac{1}{4}

Food left = \frac{54-20-3}{12} = \frac{31}{12}

Food left = 2\frac{7}{12}\ kg

Therefore,

Sheldon have left 2\frac{7}{12}\ kg of food.
