Answer:

The estimated number of bacteria after 20 hours is 40.

Step-by-step explanation:

This is a case where a geometrical progression is reported, which is a particular case of exponential growth and is defined by the following formula:

[tex]n(t) = n_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)

Where:

[tex]n_{o}[/tex] - Initial number of bacteria, dimensionless.

[tex]r[/tex] - Increase growth of the experiment, expressed in percentage.

[tex]t[/tex] - Time, measured in hours.

[tex]n(t)[/tex] - Current number of bacteria, dimensionless.

If we know that [tex]n_{o} = 30[/tex], [tex]r = 1.4[/tex] and [tex]t = 20\,h[/tex], then the number of bacteria after 20 hours is:

[tex]n(t) = 30\cdot \left(1+\frac{1.4}{100} \right)^{20}[/tex]

[tex]n(t) \approx 39.616[/tex]

[tex]n(t) = 40[/tex]

The estimated number of bacteria after 20 hours is 40.

Answer:

x= -4

Step-by-step explanation:

Answer:

4c+6≤−10

4c+6−6≤−10−6 ... subtract 6

4c≤−16...divide both sides by 4

final: c≤−4

5c-3>2

5c-3>2...add 3

5c>5...divide by 5

c>1

Answer:

it would probably be 7 hours

Answer:

25 is 6

Step-by-step explanation:

sqrt of 4 is just 2 and then plus 4 gives you 6

Answer: c

Step-by-step explanation:

3/4x = 21/2

Answer:

which answer best describes this picture

Answer:

66.4, 70.4, 223.2

Step-by-step explanation:

make the equation x + (x+4)+ 3x+24=360

then it's 5x+28=360

subtract 28 on both sides

5x=332

then divide by 5 on both sides

x=66.4

then, just plug in the numbers

Answer:

The village market

Step-by-step explanation:

Price per can at the village market

= 2.30÷5

= $0.46

Price per can at Best Food

=5.10÷10

= $0.51

Answer:

Village market

Step-by-step explanation:

Find the unit rate at village market and Best food and compare.

Village market:

Rate per can  = 2.30 ÷ 5

                      = $ 0.46

Best food:

Rate per can = 5.10 ÷ 10

                     = 0.51

0.46 < 0.51

Buying can from village market is best buy as that is less priced

Answer:

1. isosceles and acute

2. Scalene and acute

3. Equilateral and equiangular

4. Right (and isosceles ?)

(not sure ab isosceles for the last one but everything else is fine)

Answer:

15.6 meters in a minute

Step-by-step explanation:

Here's why:

1 centimeter= 0.01 meter

So, if you have 26 cm, that equals 0.26 meters.

Now, we know that there are 60 seconds in a minute.

So, we have to do 0.26 times 60 which equals 15.6 meters.

I hope this helps you! :)

Answer:

79.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

aver speed = distance / time

                   = 600 meters

                      40 seconds

                    = 15 meters per second

Answer:

5 inches

Step-by-step explanation:

formula for cube volume is l^3

so 5^3 is equal to

5 x 5 x 5

which is

25 x 5

equals

125

Hope this helps!

Answer:

5 inches

Step-by-step explanation:

V=a^3

5^3 is 125 so the answer is 5

Answer:

468,119 < 486,191

Step-by-step explanation:

compare the left numbers. Four is equal to four, so go right. 6 is less than 8, so 468,119 < 486,191

Answer:

Y=-5x-4

Step-by-step explanation:

Answer:

Your answer:

y=45x

(Y=miles driven)

(x=gas used)

Step-by-step explanation:

Answer:

Yes, it is

Step-by-step explanation:

Yes, because all x terms have null or positive integer exponents:

g(x) = -x^3 + 2x^1 + 8^0.  

Answer:

180 degrees is the answer

Step-by-step explanation:

The rule of an 180⁰ degree rotation is:

(x,y) -> (-x,-y)

So the x and y coordinates change from negative to positive or from positive to negative

9514 1404 393

Answer:

  180°

Step-by-step explanation:

When you look at the coordinates, you see that each one has been negated. That is, the image point is in the quadrant opposite the one the preimage point is in.

Every point and its image on a rotated figure makes an angle with the center of rotation that is equal to the angle of rotation. When the preimage and image points are in opposite (not adjacent) quadrants, that angle is 180°.

______

Additional comment

It can be helpful to learn to recognize certain transformations. A rotation of 90° will swap the coordinates and negate one of them. A rotation of 180° negates both coordinates without swapping them.
