Crazy boy [7]3 years ago

12*(8*x-6)-(x+9)=0

Pull out like factors :

   8x - 6  =   2 • (4x - 3) 

Equation at the end of step2:

24 • (4x - 3) - (x + 9) = 0

Solving a Single Variable Equation:

 4.1      Solve  :    95x-81 = 0 

 Add  81  to both sides of the equation : 

                      95x = 81

Divide both sides of the equation by 95:

                     x = 81/95 = 0.853

 x = 81/95 = 0.853

The top of a tower is a cone with a radius of 12 feet. The volume of the cone is 1,506.96 cubic feet. Which of these is the heig
shepuryov [24]

<span>the question does not have the options, but this does not limit its resolution
</span>
we know that
volume of the cone=(1/3)*pi*r²*h
where 
r is the radius of the cone
h is the height of the cone
r=12 ft
Volume=1506.96 ft³
h=?

clear the variable h
v=(1/3)*pi*r²*h-----> multiply by 3
3*v=pi*r²*h----> divided by (pi*r²)
h=3*v/(pi*r²)------> h=3*1506.96/(pi*12²)----> h=9.99 ft---> h=10 ft

the answer is
h=10 ft
