Radius is 5 units
Step-by-step explanation:
The radius of a circle will always be 1/2 of the diameter.
This gives the formula:

(substitute known values)

(divide 10 by 2)

Therefore the radius is five
X = # of perfomances
y = total amount of money
Income: y = 7500x
Expense: y = 5900x + 88000
Substitution:
7500x = 5900x + 88000
1600x = 88000
x = 55
y = 7500(55) = $412,500
55 performances are needed to break-even.
Answer:
-5.6
Step-by-step explanation:
first distribute the 2.5
also convert the 2/5 to decimal (0.4) because it's hard to work with both decimal and fraction
2.5y + 2.5*0.4 = -13
2.5y +1 = -13
y = -14/2.5 = -5.6
Less than one liter. It's about 1/2 pint to 1 pint
