A random sample from the 6th and 7th grade student population was taken to determine which clubs were the most popular.
gtnhenbr [62]

Using the percentage concept, it is found that 25% of 6th graders are involved in the yearbook club.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

P = \frac{a}{b} \times 100\%

In this problem, 10 out of 10 + 24 + 6 = 40 6th graders are involved in the yearbook club, hence the corresponding percentage is given by:

P = \frac{10}{40} \times 100\% = 25\%

how do i get the right hour when she runs 26. mile marathon at an average pace of 6.2 per mile. how long will take her to finish
iris [78.8K]

well, we know her rate is on average 6.2 miles per 1hr or 6.2 m/h, so how long will it be for 26 miles?

\begin{array}{ccll} miles&hrs\\ \cline{1-2} 6.2&1\\ 26&x \end{array}\implies \cfrac{6.2}{26}=\cfrac{1}{x}\implies 6.2x=26\implies x = \cfrac{26}{6.2}\implies x \approx 4.19355 \\\\\\ \textit{approximately~~~~ 4hrs 11mins and 37secs}

how did we get the minutes and seconds?  use the same rule or proportions above with hours and minutes,  4.19355, 4 + 0.19355, we know there are 60 mins per 1hr, how many in 0.19355 hrs? well, simply 60 * 19355, which gives us 11 minutes, and you can do the same thing for the seconds.
