n in (-oo:+oo)

(1/2)*n-3 = 6 // - 6

(1/2)*n-6-3 = 0

1/2*n-9 = 0 // + 9

1/2*n = 9 // : 1/2

n = 9/1/2

n = 18

Answer:

n = 6

Step-by-step explanation:

1/2 n+3=6

Subtract 3 from both sides

1/2 n = 3

Multiply both sides by 2

The height of a cone-shaped container is 70 centimeters and its radius is 15 centimeters. Cathy fills the container completely w

user100 [1]

We know that
[volume of a cone]=pi*r²*h/3
h=70 cm
r=15 cm
[volume of a cone]=pi*15²*70/3----------> 16485 cm³

if Cathy uses 500 cm³ of honey----------------> 1 day
16485 cm³--------------------------------------> X
X=16485/500-----------> 32.97 days

the answer is 33 days
