Find the equation of the line which is perpendicular to the line y=− 1 3 x+6 through the point (2,4)
nikklg [1K]

The equation of the perpendicular line is   13y=27-x

Step-by-step explanation:

Writing the given equation to slope-intercept form.

y=− 1 3 x+6

The slope of this line is 13

The perpendicular slope is -1/13

Using  the new slope and the given point into the slope-intercept form to find the y-intercept.  

4=-1/13(2)+c

2=-1/13+c

c=27/13

 y=-1/13x+27/13

So the equation of the perpendicular line is 13y=27-x

In a random sample of 30 sixth graders, 9 had traveled outside of the United States. There are a total of 120 sixth graders in t
Aleksandr-060686 [28]

36 students have traveled outside of the United States, when there are total 120 sixth graders.

<u><em>Explanation</em></u>

The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be 9: 30 = 3: 10

Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is x . That means the ratio...

x: 120 = 3:10 \\ \\ \frac{x}{120}=\frac{3}{10}  \\ \\ 10x=360\\ \\ x=\frac{360}{10} \\ \\ x= 36

So, 36 students have traveled outside of the United States.
