Answer: It would take 25 days, so C is the answer.

Step-by-step explanation:

We know that Petra walks her dog for 2/5 mi each day. We want to know how long it would take them to walk 10 mi. In order to solve this, divide 10 by 2/5

[tex]\frac{10}{1} ÷ \frac{2}{5} = \frac{10}{1} * \frac{5}{2} = \frac{50}{2} = 25

Just use basic fraction division :)

There are 416 students who are enrolled in an introductory geology course. if there are seven boys to every six girls, how many
Alenkinab [10]

\text{Let the number of boys be x and number of girls be y.}\\
\\
\text{and there are total 416 students enrolled in the course. so we have}\\
\\
x+y=416 \ \ \ \ \ \ \ \ \ \ ......(i)\\
\\
\text{also given that there are seven boys to every six girls, that is}\\
\\
\frac{x}{y}=\frac{7}{6}

\Rightarrow 6x=7y\\
\\
\Rightarrow y=\frac{6x}{7}\\
\\
\text{substitute this value of y in (i), we get}\\
\\
x+\frac{6x}{7}=416\\
\\
\Rightarrow \frac{7x+6x}{7}=416\\
\\
\Rightarrow \frac{13x}{7}=416\\
\\
\Rightarrow x=\frac{416\times 7}{13}\\
\\
\Rightarrow x=224

Hence the number of boys in the course are: 224
