90 games since each team would be playing 9 games (one against every other team)
Answer:
(a)11 hours
(b)19.5 hours
(c)2.5 hours
Step-by-step explanation:
The number of hours of daylight, H, on day t of any given year in a particular city can be modeled by the function :
![H(t)=11+8.5\sin\left(\dfrac{2\pi}{365}(t-83)\right)](https://tex.z-dn.net/?f=H%28t%29%3D11%2B8.5%5Csin%5Cleft%28%5Cdfrac%7B2%5Cpi%7D%7B365%7D%28t-83%29%5Cright%29)
(a)When t=83
![H(83)=11+8.5\sin\left(\dfrac{2\pi}{365}(83-83)\right)\\=11+8.5\sin 0\\=11$ hours](https://tex.z-dn.net/?f=H%2883%29%3D11%2B8.5%5Csin%5Cleft%28%5Cdfrac%7B2%5Cpi%7D%7B365%7D%2883-83%29%5Cright%29%5C%5C%3D11%2B8.5%5Csin%200%5C%5C%3D11%24%20hours)
(b)When t=175
![H(175)=11+8.5\sin\left(\dfrac{2\pi}{365}(175-83)\right)\\=11+8.5\sin\left(\dfrac{2\pi}{365}\times 92 \right)\\=11+8.5\\=19.5$ hours](https://tex.z-dn.net/?f=H%28175%29%3D11%2B8.5%5Csin%5Cleft%28%5Cdfrac%7B2%5Cpi%7D%7B365%7D%28175-83%29%5Cright%29%5C%5C%3D11%2B8.5%5Csin%5Cleft%28%5Cdfrac%7B2%5Cpi%7D%7B365%7D%5Ctimes%2092%20%5Cright%29%5C%5C%3D11%2B8.5%5C%5C%3D19.5%24%20hours)
(b)When t=358
![H(175)=11+8.5\sin\left(\dfrac{2\pi}{365}(358-83)\right)\\=11+8.5\sin\left(\dfrac{2\pi}{365}\times 275 \right)\\=11-8.5\\=2.5$ hours](https://tex.z-dn.net/?f=H%28175%29%3D11%2B8.5%5Csin%5Cleft%28%5Cdfrac%7B2%5Cpi%7D%7B365%7D%28358-83%29%5Cright%29%5C%5C%3D11%2B8.5%5Csin%5Cleft%28%5Cdfrac%7B2%5Cpi%7D%7B365%7D%5Ctimes%20275%20%5Cright%29%5C%5C%3D11-8.5%5C%5C%3D2.5%24%20hours)
Answer:
15x+12/18x+32x
Step-by-step explanation:
Hopefully this helped, if not HMU and I will get u a better answer.

" break even " is when ur expenses = revenue.....there is no profit made when u break even
expenses : 0.35x + 770
revenue (ur income) : 0.55x
so they have to equal to break even...so set them equal to each other and solve for x
0.35x + 770 = 0.55x
770 = 0.55x - 0.35x
770 = 0.2x
770 / 0.2 = x
3850 = x <== they must sell 3850 copies to break even
