0.35 rational or irrational

2 answers:

6 0

A rational number is a number that can be expressed as a fraction (a/b) where a and b are integers and b is not equal to 0 (because you cannot divide by 0).

.35 can also be written as 35/100. 35 and 100 are both integers, and 100 is not equal to 0. so, by definition, .35 is rational.

The doubling period of a bacterial population is 20 20 minutes. At time t = 100 t=100 minutes, the bacterial population was 9000

Nuetrik [128]

Answer:

The initial population was 2810

The bacterial population after 5 hours will be 92335548

Step-by-step explanation:

The bacterial population growth formula is:

$P = P_0 \times e^{rt}$

where P is the population after time t, $P_0$ is the starting population, i.e. when t = 0, r is the rate of growth in % and t is time in hours

Data: The doubling period of a bacterial population is 20 minutes (1/3 hour). Replacing this information in the formula we get:

$2 P_0 = P_0 \times e^{r 1/3}$

$2 = e^{r \; 1/3}$

$ln 2 = r \; 1/3$

$ln 2 \times 3 = r$

$2.08 \% = r$

Data: At time t = 100 minutes (5/3 hours), the bacterial population was 90000. Replacing this information in the formula we get:

$90000 = P_0 \times e^{2.08 \; 5/3}$

$\frac{9000}{e^{2.08 \; 5/3}} = P_0$

$2810 = P_0$

Data: the initial population got above and t = 5 hours. Replacing this information in the formula we get:

$P = 2810 \times e^{2.08 \; 5}$

$P = 92335548$

If John has 1107 bars of chocolate and wants to give each of his 10 friends an even amount each, what would each friend get? Wha

Nutka1998 [239]

Divide 1107 by 10, for example:

1107/10= 110.7

The decimal point means the remainder, this means John will only get 7 chocolate bars.

If You want it split evenly between ALL of them, divide by 1107 by 11, for example:

1107/11= 100.6, which would leave six bars left, so I think the logical offer would be the first answer I gave you.

I hope this helped!
