Total degrees of a circle: 360’
Pie chart total: 360’/10=36

So every angle divided by 10 equals the number of pupils:

Bus: 120’/10=12 pupils.
Walk: 90’/10=9 pupils.

360’-(120’-90’)=150’ remaining

150’/2=75’

Car and bike are equal:

75’/2=7.5 pupils for car and bike.

Find the coordinates of the other endpoint of the​ segment, given its midpoint and one endpoint.​ (Hint: Let​ (x,y) be the unkno
spin [16.1K]
The other endpoint is (1, -17).

The midpoint formula is:

m=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Using our midpoint and endpoint, we have:
(6, -11) = (\frac{11+x_2}{2}, \frac{-5+y_2}{2})&#10;\\&#10;\\6=\frac{11+x_2}{2} \text{ and } -11=\frac{-5+y_2}{2}&#10;

For the first equation (to find the x-coordinate) we will multiply both sides by 2:
6\times2=\frac{11+x_2}{2}\times 2&#10;\\&#10;\\12=11+x_2

Subtract 11 from both sides:
12 - 11 = 11+x₂ - 11
1 = x₂

For the second equation (the y-coordinate) we multiply both sides by 2:
-11\times2=\frac{-5+y_2}{2}\times 2&#10;\\&#10;\\-22=-5+y_2

Add 5 to both sides:
-22+5 = -5+y₂ + 5
-17 = y₂

This means that (x₂, y₂) is at (1, -17).
