Step-by-step explanation:
Z^2 - 2z - 35 = 0
(z - 7)(z + 5) = 0
z - 7 = 0
z = 7
z + 5 = 0
z = -5
solution is : z = 7,-5
The manager should sell the chair for $249.75 :)
Percents are parts of 100, so we divide 53 by 100 to find the decimal form of 53%.

For a cylindrical tank, volume = πr²h
Where r = radius = diameter/2 = 6/2 = 3m
height , h = 3m
Volume = 3.14 * 3² * 3 = 84.78
Volume ≈ 84.8 m³
