The answer is -1/16 or -0.0625, do you need to see work?
Answer:
If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .
Consider the sum of the measures of the exterior angles for an n -gon.
N=180n−180(n−2)
Distribute 180 .
N=180n−180n+360 =360.
Step-by-step explanation:
The total cost would be $698.75 because 15×30.25=453.75 then add the 245 and boom you get your answer.

1. (2√5)/5
2. -44√7
3. 8√17
4. -6√3+12
For 1: Multiply the numerator and denominator by √5:

For 2: Simplify √112:
√112 = √(2*56) = √(2*2*28) = √(4*4*7) = 2*2√7 = 4√7
Now multiply by the -11 coefficient:
-11(4√7) = -44√7
For 3: Add the radicals as you would variables that are like terms.
For 4: Multiply by the conjugate. The conjugate of the denominator has the same values with the sign of the radical changed:
X= number of student tickets soldx+75= number of adult tickets sold
Add the number of student and adult tickets together to total 725 tickets
x + (x + 75)= 725
combine like terms
2x + 75= 725subtract 75 from both sides
2x= 650divide both sides by 2
x= 325 adult tickets
x + 75= 400 student tickets
ANSWER: There were 325 adult tickets sold
