Answer: 3/5 or 0.6 gallons
Step-by-step explanation:
Ok so this is a Pythag question...
So the first step would be A squared plus B squared equals C squared
Your A squared would be 12
You do not have B squared value yet
Your C squared Would be 16
So your equation is 12 squared plus B squared equals 16 squared
Simplified that would be 144 plus B squared equals 256
Subtract 144 from both sides and you get 112 equals B squared so do that dividing symbol thing on both sides and you get 10.58 equals c
C= 10.58

Answer:
2028 ft
Step-by-step explanation:
Let the feets of boards sold to get profit be x hence with the price of $1.13 which is inclusive of profit, the total sales will be 1.13 x
The cost per day will equally be the sum of variable cost which considers the feets of boards and the daily fixed charge. Considering the variable of $0.03 and fixed charge of $2230.80 then the equation is represented as 0.03x+2230.80
Relating the two equations then
1.13x=0.03x+2230.80 and rearranging like terms
1.13x-0.03x=2230.80
1.1x=2230.8
X=2230.8/1.1=2,028 ft
Therefore, to maximize daily profit, 2028 ft must be sold
