Answer:
290 in^2
Step-by-step explanation:
So what you do is you use the formula of the surface area of a rectangle which is SA=2lw+2lh+2hw.
The length=5. The width=5. The height=12.
You put those numbers into the formula.
2(5)(5)+2(5)(12)+2(12)(5)=290 in^2.
5.3851648071..... is the irrational number your looking for
Answer:
55 performances
Step-by-step explanation:
The first equation will be the total cost. The total cost has $88,000 already and then $5,900 is added with each performance. So the equation would be 88,000+5,900x because x will represent the number of performances.
y = 88,000 + 5,900x
The next equation will be how much the performances earn. If they earn $7,500 with each performance then the equation will be 7,500x, with x representing the number of performances
y = 7,500x
Now set the equations equal to each other and solve for x
7,500x = 88,000 + 5,900x
1,600x = 88,000
x = 55
They need to have 55 performances for the cost and the revenue to break even.
