Answer:
7
Step-by-step explanation:
Let's say our sum is s.
s = 10 right angles
a right angle is 90 degrees
s = 10 (90)
s= 900
Given the amount of sides in a polygon (n), the sum of the interior angles is equal to
(n-2) * 180
Therefore, the sum of the interior angles is equal to
(n-2) * 180 = 900
divide both sides by 180 to help isolate n
n-2 = 5
add 2 to both sides to isolate n
n = 7
Answer:
the answer is obviously B
Step-by-step explanation:
-1/4*x^2-x+3=-1/4*(x^2+4x)+3=-1/4*(x^2+4x+4)+4=-1/4*(x+2)^2+4
x0=-2
Hi there!
The answer is C.

The question has already revealed the following data:
x = number of tickets.
y = number of t-shirts.
We can now find the total cost function.
The cost of 1 ticket is $ 25
and therefore the total cost for all of the tickets is $25 ×
the amount of tickets, mathematically $25 × x, hence 25x.
The cost of 1 shirt is $ 12
and therefore the total cost for all of the tickets is $12 ×
the amount of shirts, mathematically $12 × y, hence 12y.
When making the total cost function, don't forget to include the service fee of $4.
Now we can conclude that the total cost function is the following:

Maya only has $130 and therefore the total cost must be smaller than or equal to this amount of money. The answer is C.
