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 $2^{48}$ .

There are 312 cards in 6 deck of playing cards write the ratio as a fraction them find the unit rate

ladessa [460]

Answer:

6x: 312

x: 52

Step-by-step explanation:

Let the deck be denoted by x then

6x: 312

There are 312 cards in 6x decks

In 1 deck x there are 312/6= 52 cards

6x: 312

6x/6: 312/6 Cancelling both sides by 6

x: 52

In ratio both the sides are divided by the same number to get equivalent fractions.

In 1 deck there are 52 cards
