Answer:

Density of mixture is 7.0 g/cm^{3}.

Step-by-step explanation:

Density of mixture = density of water in the mixture + density of oil in the mixture

Given: water and oil were mixed in a ratio 3:5

           density of water is 1.0 g/cm^{3} and that of oil is 0.8 g/cm^{3}.

Then,

density of water in the mixture = 3 x 1.0 g/cm^{3}

                                   = 3.0 g/cm^{3}

Density of the volume of water in the mixture is 3.0 g/cm^{3}.

density of oil in the mixture = 5 x 0.8 g/cm^{3}

                                              = 4.0 g/cm^{3}

Density of oil in the mixture is 3.0  g/cm^{3}.

So that,

Density of mixture = 3.0 + 4.0

                               = 7.0

Density of mixture is 7.0 g/cm^{3}.

Monica [59]

Answer:

an open circle will be at -2(since the inequality sign does not include "equal to") and the line is drawn to the left of the circle (since the sign is "left than")

Step-by-step explanation:

Given the inequalities

17+4x < 9

Subtract 17 from both sides

17+4x -19 < 9 - 17

4x < -8

Divide both sides by 4

4x/4 < -8/4

x < -2

To represent the solution on a number line, an open circle will be at -2(since the inequality sign does not include "equal to") and the line is drawn to the left of the circle.
