3/7 of 8th graders play sports. is 3/5 of the 8th graders that play sports are boys, what fraction of the 8th graders are boys

Svetach [21]

Answer:

$\dfrac{9}{35}$ is the fraction of 8th graders who are boys.

Step-by-step explanation:

Let total number of 8th graders = $x$

Given that, $\frac{3}{7}$ of 8th graders play sports

$\Rightarrow$ 8th graders who play sports = $\frac{3}{7} \times x$

Also, Given that, $\frac{3}{5}$ of 8th graders that play sports are boys

Number of 8th graders that play sports, and are boys = $\frac{3}{5} \times \text{Number of 8th graders who play sports}$

$\Rightarrow \dfrac{3}{5} \times \dfrac{3}{7} \times x\\\Rightarrow \dfrac{9}{35} \times x$

Hence, the answer is:

$\dfrac{9}{35}$ is the fraction of 8th graders who are boys.

The population of a culture of cells grows according to the function P(t)= 90t/ t + 1, where t> or =0 is measured in weeks. C

butalik [34]

Answer:

The average rate of change is $\frac{18}{5}$

Step-by-step explanation:

Given function that shows the population of a culture of cells,

$P(t)=\frac{90t}{t+1}------(1)$

Where, t represents the number of weeks.

Thus, the average rate of change in the population over the interval [0,24],

$m=\frac{P(24)-P(0)}{24-0}$

From equation (1),

$=\frac{\frac{90\times 24}{24+1}-\frac{90\times 0}{0+1}}{24}$

$=\frac{\frac{2160}{25}-\frac{0+1}{0}}{24}$

$=\frac{2160}{25\times 24}$

$=\frac{2160}{600}$

$=\frac{18}{5}$
