A culture of bacteria has an initial population of 15000 bacteria and doubles every 3 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t ​ =P 0 ​ ⋅2 d t ​ , where P_tP t ​ is the population after t hours, P_0P 0 ​ is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 20 hours, to the nearest whole number?

Answer:2

Step-by-step explanation:1+1=2

Answer: $4.99

Step-by-step explanation:

The store discounted all jewelry by 1/4 which means that they removed 1/4 of the price of an item off of it.

The discount on a $19.96 bracelet would therefore be:

= 1/4 * 19.96

= $4.99

This means that the item will sell for:

= 19.96 - 4.99

= $14.97

Answer:

root 24+12 is root 36 which is equal to 6

4 root of 6 is 36 the power of 2 which is equal to 36

5 the power of 2 is 25

then when we multiple 6x36x25

it's 5400

Answer:

Answer = 1080

Step-by-step explanation:

Hey there!

Here's the initial equation:

[tex]\sqrt{24+12} * \sqrt{6^4 * 5^2}[/tex]

What I'll do now is sum what's in the left root.

[tex]\sqrt{36} * \sqrt{6^4 * 5^2}[/tex]

Since [tex]\sqrt{36}[/tex] = 6, we get this equation:

[tex]6 * \sqrt{6^4 * 5^2}[/tex]

Now: You can see that the five is elevated to the second. Since it is a square root, you can just pop it out:

6 * [tex]5\sqrt{6^4}[/tex]

6 * 5 = 30, so here's what you got:

[tex]30\sqrt{6^4}[/tex]

At this point you should see that:

[tex]6^4[/tex] = 6 * 6 * 6 * 6

6 * 6 * 6 * 6 = 36 * 6 * 6

36 * 6 * 6 = 36 * 36

36 * 36 = 36²

Now you have this:

[tex]30\sqrt[2]{36^2}[/tex]

Since it is a square root and a square number, you can do just as with the five: Pop it out! (When you take numbers out of the root they multiply, they do not add. Never forget that ;).

30 * 36 = 1080

Answer = 1080

Answer:

[tex]7x^{8}[/tex]

Answer:

C

Step-by-step explanation:

Given:

The a box-and-whisker plot if a data set.

To find:

The percentage of data values that are less than 66.

Solution:

From the given box-and-whisker plot, it is clear that the number 66  is the highest value of the data set.

It means all the values of the data set are less than 66 and no value can be more than 66.

All value means 100%.

Therefore, 100% of data values are less than 66.

Answer:

to Region? Climate varies from region to region. This variation is driven by the uneven distribution of solar heating, the individual responses of the atmosphere, oceans and land surface, the interactions be- tween these, and the physical characteristics of the regions.

Answer:

72.033 ft

Step-by-step explanation:

To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.

[tex]\frac{18.47}{1}=\frac{y}{3.9}[/tex]

Step 1: Switch sides

[tex]\frac{y}{3.9}=\frac{18.47}{1}[/tex]

Step 2: Apply rule: [tex]\frac{a}{1}=a[/tex]

[tex]\frac{y}{3.9}=18.47[/tex]

Step 3: Multiply both sides by [tex]3.9[/tex]

[tex]\frac{3.9y}{3.9}=18.47\cdot \:3.9[/tex]

Step 4: Simplify

[tex]y=72.033[/tex]

The bear can run 72.033 feet in 3.9 seconds

Answer:

The answer is line D

Step-by-step explanation:

Answer:

3/10

Step-by-step explanation:

We have to list out the numbers that are divisible by 6 and 7 that we can find between 1 and 30

so, we have this as;

6,7,12,14,18, 21, 24,28 and 30

The count we have here is 9

The total number we have is 30

So the probability is simply the count we have divided by 30

so we have this as ; 9/30 =

3/10

Answer:

x=4, y=-1. (4, -1).

Step-by-step explanation:

x+5y=-1

5x+15y=5

---------------

-5(x+5y)=-5(-1)

5x+15y=5

--------------------

-5x-25y=5

5x+15y=5

----------------

-10y=10

y=10/-10

y=-1

x+5(-1)=-1

x-5=-1

x=-1+5

x=4

Answer:

4/3pi

Step-by-step explanation:

Length of an arc  = r theta

Given radius r = 30

length of arc  l = 40

Substitute

40 = 30theta

theta = 40/30

theta = 4/3 pi

Hence the angle marked B is 4/3pi
