Answer:
Quadratic equations have the solution
x = [-b +-sqr root(b^2 -4ac)] / 2a
In the given equation a = l; b = m and c = n So,
x = [-m +-sqr root(m^2 -4*l*n)] / 2*l
Step-by-step explanation:
You would subtract 180-50
b. 130 degrees
First, solve for the volume (V) of each cylinder by the equation,
V = πd²h / 4
where d and h are diameter and height, respectively. Substituting the given values,
V = π(6.19 cm)² x (6 cm) / 4 = 180.56 cm³
To determine the number of cylinders needed, divide the volume of the solid block by the volume of the cylinder,
n = 360 cm³ / 180.56 cm³ = 1.99
Thus, approximately 2 cylinders are needed to mold one block of gold.
