Answer:
The estimate is not correct?
Step-by-step explanation:
Given data
Area of wall = 18*8
=144ft^2
=4*144
=576ft^2
Area of doors
=3*7
=21ft^2
=2*21
=42ft^2
Area of window
=3*5
=15ft^2
Hence the total surface area of the room
=576-42-15
=519ft^2
The amount of paint needed= 519/300= 1.73
Approximately 2 gallons
We are told that 1 gallon will cover 300ft^2
Hence 3 gallons will cover 300*3= 900ft^2
Therefore the painter overestimated the amount of paint needed
As 2 gallons will do the job
Answer: 0
Step-by-step explanation:
Let statements :
Let x be the number of tickets sold for an adult
Let y be the number of tickets sold for a child
Equations :
x + y = 280 OR y = 280 - x
4x + 2y = 1320
Substitution (sub the 2 equations in together) :
4x + 2(280 - x) = 1320
4x + 560 - 2x = 1320
2x = 1320 - 560
x = 760/2
x = 380
x is the number of tickets sold for the adults. meaning that 380 adults went.
Find the # of children :
x + y = 380
we know that x = 380
380 + y = 380
y = 380 - 380
y = 0
Conclusion :
No children went because the movie was rated R. Only adults attended.
