When you mix two colors of paint in equivalent ratios, the resulting color is
vredina [299]

Answer:

Step-by-step explanation:

From the given table,

To prepare a mixture of a paint, two paints of different shades have been added in the same ratio,

Since, 2 cups of blue paint are mixed with 10 cups of yellow paint

Therefore, ratio in which these shades have been added = \frac{\text{Pink}}{\text{Blue}}

                                                                                                = \frac{10}{2}

                                                                                                = \frac{5}{1}

                                                                                                = 5 : 1

For 1 cup of blue paint number of cups of yellow paint required,

\frac{x}{1}=\frac{5}{1}

x = 5 cups

For 3 cup of blue paint number of cups of yellow paint required,

\frac{x}{3}=\frac{5}{1}

x = 15 cups

Cups of blue paint                Cups of yellow paint

            2                                             10

            1                                               5

What is the volume of a certain cube? (1) The sum of the lengths of the edges of the cube is 36. (2) The surface area of the cub
german

Answer:

(1) The sum of the lengths of the edges of the cube is 36.

A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3

Volume = 3*3*3 = 27

(2) The surface area of the cube is 54.

A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)

6s^2 = 54

s = 3

Volume = 3*3*3 = 27

Step-by-step explanation:

All you need to uniquely define a cube is any one measurement - length of a side/edge, area of a surface, volume etc. If you have any one of them, you can uniquely determine the others. So each statement alone is sufficient here.

To show how,

(1) The sum of the lengths of the edges of the cube is 36.

A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3

Volume = 3*3*3 = 27

(2) The surface area of the cube is 54.

A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)

6s^2 = 54

s = 3

Volume = 3*3*3 = 27
