Answer:
He needs to make at least 6 visits.
Step-by-step explanation:
The signing up amount, 20, is a fixed amount.
The amount he receives per movie is 12.5 times the number of visits, v, or 12.5v.
The total amount of points he earns is the sum of the fixed amount and the amount due to the number of visits.
earned points = 12.5v + 20
He must earn 95 points or more.
12.5v + 20 ≥ 95
Subtract 20 from both sides.
12.5v ≥ 75
Divide both sides by 12.5
v ≥ 6
He needs to make at least 6 visits.

Step-by-step explanation:
it is not a function because 9 and three are a pair but so are 27 and 3. that makes it not a function
At least do number 3 so I can help with the rest. That ok with you?
So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:
12π / π = 12
Now we halve the diameter to get the radius:
12 / 2 = 6
The area of a circle is π x radius²
So the area is:
·π x 6² = 36π· (or 113 not in terms of π)
