The barn, the ground, and the ladder form a right triangle. If we represent the height on the barn by y, then the Pythagorean theorem tells us
... hypotenuse² = (side1)² + (side2)²
... (12 ft)² = (3 ft)² + y² . . . . . . . . . . . . fill in given information
... 144 ft² - 9 ft² = y² = 135 ft² . . . . . .subtract (3 ft)²
... y = 3√15 ft ≈ 11.6 ft . . . . . . . . . . . take the square root
The ladder reaches 11.6 feet high on the barn.

-3.7 + w = 9.24
Solving
-3.7 + w = 9.24
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '3.7' to each side of the equation.
-3.7 + 3.7 + w = 9.24 + 3.7
Combine like terms: -3.7 + 3.7 = 0.0
0.0 + w = 9.24 + 3.7
w = 9.24 + 3.7
Combine like terms: 9.24 + 3.7 = 12.94
w = 12.94
Simplifying
w = 12.94</span>
Because AB=RS=8m, ArcRS=Arc AB=ArcAR+ArcRB=55+66=121
Answer:
$160/5
Step-by-step explanation:
160/5 would be 32 and 315/9 would be 35. 32 is less than 35 so $160/5 would be the better deal.
