Answer:
30 hours
Step-by-step explanation:
We can use ratios to solve
5 hours x hours
-------------- = -------------
3 walls 18 walls
Using cross products
5*18 = 3x
Divide each side by 3
5*18/3 = 3x/3
30 =x
Sin(12) ≈ 0.208
cos(x) = 0.208
cos(x) = sin(12)
cos(78) = sin(12)
cos(12) ≈ 0.978
cos(68) ≈ 0.375
cos(102) ≈ -0.208
cos(78) ≈ 0.208
The answer is D.
Answer:
28% is your awnser
Step-by-step explanation:
um If you look up what is 35 percent of 80 you will get your awnser
G(f(12))
f(12) = 9 - 12 = -3
g(-3) = (-3)^2 + 4 = 9 + 4 = 13
