Using the Pythagorean theorem:
a^2 + b^2 = c^2
a and b are the sides and c is the hypotenuse.
The length of the ladder would be the hypotenuse and the base away from the wall would be one side.
So now we have:
5.5^2 + b^2 = 9^2
Simplify:
30.25 + b^2 = 81
Subtract 30.25 from each side:
b^2 = 81 - 30.25
b^2 = 50.75
Take the square root of both sides:
b = √50.75
b = 7.123
Rounded to the nearest tenth of a foot = 7.1 feet.
Answer: x = -1
Step-by-step explanation:
(4x + 4) + 4 = 4 subtract 4 from each side
(4x + 4) = 0 subtract 4 from each side again
4x = -4 divide each side by 4
x = -4/4
x = -1
Answer:
$15.39
Step-by-step explanation:
The volume of the cylinder is given by ...
V = πr²h = 3.14·(3.5 in)²·(8 in) = 307.72 in³
Since each cubic inch costs $0.05, the total cost is ...
$0.05 · 307.72 ≈ $15.39
