To solve this simply divide 4 by 3 and use the long division and do the same for 11 and 9, then compare the values.

Holaaa!

To compare 3/4 and 9/11 we must first make the denominators the same number. To do this, we can multiply the numerators and denominators of the numbers by eachother. See below.

Denominators - 4 and 11 - we are going to multiply these to find out what the denominator of both our fractions will be.

4 * 11 = 44 - the denominator is therefore, 44.

Now we need to multiply the numerators by the opposite denominators. Numerators - 3 and 9 - (multiply by the opposite denominators) - 3 * 11 = 33 (33/44) - 9 * 4 = 36 (36/44)

Now that we've done that, we can compare our fractions.

9/11 = 36/44 ? 3/4 = 33/44

Which is greater? The answer is 9/11 (36/44)

9/11 > 3/4

I truly hope this helps you!

A freshly inoculated bacterial culture of Streptococcus contains 100 cells. When the culture is checked 60 minutes later, it is

Luba_88 [7]

Answer:

$P(t) = 100e^{0.0251t}$

The doubling time is of 27.65 minutes.

Step-by-step explanation:

Exponential equation of growth:

The exponential equation for population growth is given by:

$P(t) = P(0)e^{kt}$

In which P(0) is the initial value and k is the growth rate.

A freshly inoculated bacterial culture of Streptococcus contains 100 cells.

This means that $P(0) = 100$ . So

$P(t) = 100e^{kt}$

When the culture is checked 60 minutes later, it is determined that there are 450 cells present.

This means that $P(60) = 450$ , and we use this to find k. So

$450 = 100e^{60k}$

$e^{60k} = 4.5$

$\ln{e^{60k}} = \ln{4.5}$

$60k = \ln{4.5}$

$k = \frac{\ln{4.5}}{60}$

$k = 0.0251$

So

$P(t) = 100e^{0.0251t}$

Doubling time:

This is t for which P(t) = 2P(0) = 200. So

$200 = 100e^{0.0251t}$

$e^{0.0251t} = 2$

$\ln{e^{0.0251t}} = \ln{2}$

$0.0251t = \ln{2}$

$t = \frac{\ln{2}}{0.0251}$

$t = 27.65$

The doubling time is of 27.65 minutes.
