The measure of the angle is half the measure of the opposite arc.
.. ? = 78°/2 = 39°
Answer:
srry
Step-by-step explanation:
The first thing we must do for this case is to define variables.
We have then:
x: number of slices
y: total cost
We write the linear function that relates the variables.
We have then:

Then, we evaluate the number of slices to find the total cost.
-two slices cost:
We substitute x = 2 in the given equation:

Answer:
two slices = 2.2 $
-ten slices cost:
We substitute x = 10 in the given equation:

Answer:
ten slices = 11 $
-half a slice cost:
We substitute x = 1/2 in the given equation:

Answer:
half a slice = 0.55 $
At least about 20 points it can depend on the class but not really.
2x=y
two times the number of minutes = the amount of pages
