Total tickets sold = 417
2 fractions goes to students.
1 fraction goes to adults.
Total fractions of tickets
= 2 + 1
= 3 fractions
Since adults = 1 fraction
1 fraction = 417 ÷ 3
= 139 tickets
Answer:
A
Step-by-step explanation:
Perpendicular bisector of a line divides the line into 2 equal parts and it is perpendicular to the line.
First let's find the midpoint of CD. The point is where the perpendicular bisector will cut through the line.
midpoint= 
Thus, midpoint of CD

Gradient of line CD

The product of the gradients of perpendicular lines is -1.
gradient if perpendicular bisector(1)= -1
gradient of perpendicular bisector= -1
y=mx +c, where m is the gradient and c is the y-intercept.
y= -x +c
Subst a coordinate to find c.
<em>Since the perpendicular bisector passes through the point (8, -10):</em>
When x=8, y= -10,
-10= -8 +c
c= -10 +8
c= -2
Thus, the equation of the perpendicular bisector is y= -x -2.

The segment is about 6cm
and 6cm is between 5.4 and 6.5
Well you need an equation because how many friends were at the party? x*12x10=w thats your equation or however you want to put it. the letters are your variables
