Answer:533.33 meters

Step-by-step explanation:

The mile would be four laps around a track which is 400 meters so 400x4 divided by 3 (I ran track that’s the only reason I figured this out)

Suppose that a colony of bacteria starts with 1 bacterium and doubles in number every half hour. how many bacteria will the colo

OverLord2011 [107]

Let $a_n$ represent the number of bacteria after $\frac{n}{2}$ hours.

so

$a_0$ is the number of bacteria after 0/2 = 0 hours

$a_1$ is the number of bacteria after 1/2 hours

$a_2$ is the number of bacteria after 2/2 = 1 hours and so on

so if we list a few terms of this sequence, we have:

$a_0=1$

$a_1=1*2$

$a_2=1*2*2$

$a_3=1*2*2*2$

$a_4=1*2*2*2*2$

so clearly, $a_n$ , the number of bacteria after $\frac{n}{2}$ hours, is equal to $2^{n}$ .

$a_4_8$ is the number of bacteria after

$\frac{n}{2}=\frac{48}{2}= 24$ hours.

Thus, we calculate $a_4_8$ , which is $2^{48}$ .

Answer: the number of bacteria after 24 hours is $2^{48}$ .

what is the ratio of a rectangle if one side is 12 and the other side is 16 ? what is the ratio if one side is 8 and the other s

Vika [28.1K]

Answer:

3:4

4:5

Step-by-step explanation:

The ratios are ...

short side : long side = 12 : 16 = 3 : 4

and for the other rectangle, ...

short side : long side = 8 : 10 = 4 : 5

_____

To reduce the ratio to lowest terms, divide each number by their greatest common factor. 12 and 16 have a common factor of 4: 12=4·3, 16=4·4. 8 and 10 have a greatest common factor of 2.
