<h3>What is the total cost for utilities last month?</h3>
The total cost for utilities last month can be determined by multiplying the volume of the stadium by the cost per cubic foot.
The volume of the stadium can be determined by using the formula for the volume of a hemisphere.
Volume of a hemisphere = Volume of a hemisphere = (2/3) x (n) x (r^3)
n = 22/7
r = radius
2/3 x 22/7 x 150³ = 7071,428.57
The total cost for utilities last month = 7071,428.57 x 0.05 = 353,571.43

Answer:
x = 13
Step-by-step explanation:
6x + 14 + 4x - 8 + 2x + 18 = 180 {Angle sum property of tiangle}
6x + 4x + 2x + 14 - 8 +18 = 180 {Combine like terms}
12x + 24 = 180 {Subtract 18 from both sides}
12x = 180 - 24
12x = 156 {Divide both sides by 12}
x = 156/12
x = 13
Answer:
64.7 when rounded up to one decimal place
Step-by-step explanation:
Answer:
Let x = Kilometers by bus
then x + (x + 350) = 1100
2x = 750
x = 375 by bus
x - 350 + x = 1100
2x = 1450
x = 725 by train
