Answer:
12.2
Step-by-step explanation:
Solution:
we are given that
The fairy tale spectacular is coming to town. Admission to the fair costs $32.50 and each ride costs $.80.
You have $50 to spend at the fairy tale spectacular including admission.
Suppose you took x ride, then we can write.
So the inequality can be written as below:

PartB:
Now lets solve the inequality

Hence you can take a maximum of 21 rides.
Answer:
Radius = 2.
Step-by-step explanation:
We have been given equation of the circle which is
.
Now we need to find the radius of the given circle
.
To find that let's compare with the formula of the circle with standard equation of the circle
, where r is the radius.
We get 
take square root of both sides.

Hence radius of the given circle is r = 2.
