Answer:
Choice B, 90
Step-by-step explanation:
The answer definitely 15x + 25y >= 700 for the inequality . So the number of small prints is more than 3 times the large prints . We can also have here the number of small prints : x = 3y . So the equation we have is 15(3y) + 25y >= 700 . We take the least amount to solve :
15(3y) + 25y = 700
=> 45y + 25y = 700
=> 70y = 700
=> y = 10 .
So the amount of large prints is 10
The amount of small prints is 10x3 = 30
So it would be ( 30,10 )
If the span is 16-ft, then the half-span is 8-ft.
Pitch = (rise) / (half-span) = 6/8 = 3/4 or 0.75 or 75% .
That's a VERY steep roof !
Inequality :
The least whole number of hours : 27 hours.
