Answer:

5

Step-by-step explanation:

Let a = number of pieces of chocolate bought by Amin.

Let b = number of pieces of chocolate bought by Bob.

b = 2a

(a - 3)(b - 3) = 14

ab - 3a - 3b + 9 = 14

a(2a) - 3a - 3(2a) = 5

2a^2 - 3a - 6a = 5

2a^2 - 9a - 5 = 0

(2a + 1)(a - 5) = 0

2a + 1 = 0  or  a - 5 = 0

a = -1/2  or  a = 5

Amin cannot have bought -1/2 pieces of chocolate, so we discard the soluion a = -1/2.

a = 5

Answer: 5

The radius of the base of a cylinder is 10 centimeters, and its height is 20 centimeters. A cone is used to fill the cylinder wi
Leya [2.2K]

Answer: 24times

Step-by-step explanation:

Formula for the volume of a cylinder                         = πr²h

Volume of the cone                                                      = 1/3πr²h

Therefore the volume of the cylinder               = 22/7 x 10² x 20

                                                                     = 22/7 x 10 x 10 x 20

                                                                                = 6285.71cm³

Therefore , the volume of the cone             = 1/3 x 22/7 x 5² x 10

                                                                     = 1/3 x 22/7 x 5 x 5 10

                                                                                  = 5500/21

                                                                                  = 261.9cm³

Therefore the number of times needed to use the completely filled cone to completely filled the cylinder with water                                                                                                                       = 6285.71/261.9

                                                                                = 24times.
