No, is not finish

1/8+3/8+2/8+1/8= 7/8

they need 1/8 more

no

1 - 1/8 - 3/8 - 2/8 - 1/8 = 1/8 remaining

What is 2/10 divided by 2/4

shtirl [24]

Given:

$\dfrac{2}{10}$ divded by $\dfrac{2}{4}$ .

To find:

The solution for the given division problem.

Solution:

We have, $\dfrac{2}{10}$ divded by $\dfrac{2}{4}$ . It can be written as

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{10}\times \dfrac{4}{2}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2\times 4}{10\times 2}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{8}{20}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{5}$

Therefore, the solution for the given division problem is $\dfrac{2}{5}$ .

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:

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

$P = 92335548$

Carol Ann buys a TV at 70% off the original price. If she pays $120, what was the original price of the TV?

Keith_Richards [23]

If the TV is 70% off, then that means she paid 30% of the original cost. If 30% of the original cost is $120, then...

30% * x = 120
.30x = 120
x = 120/.30
x = 400

The original cost was $400
