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}.

Salma purchased a prepaid phone card for $15 Long distance calls cost 6 cents a minute using this card. Salma used her card only
Fiesta28 [93]

Answer:

m=17

Step-by-step explanation:

$15 minus $0.14(# minutes) = $12.62

 

15 - .14m = 12.62

 

.14m = 15 - 12.62

 

.14m = 2.38

 

m = 2.38/.14

 

m = 17 minutes

State whether every point on the graph is a solution of the equation. Explain why or why not. x – 4y = –4 A. Every point shown o
PtichkaEL [24]
B!

The equation x-4y= -4 is the graph, right? So that means when x is, lets say, 2, then:

2-4y= -4

Simplify
-4y=-6
y=3/2

Now if you think about it, if you plug in any number for x and get some value of y, that is the point on the graph at that x value.

Hope this helps!

Answer:

Range of the function → {24, 375}

Step-by-step explanation:

Domain of the function f(x) = 3x³ is {2, 5}

we have to find the range when its domain is {2, 5}

Since x-values of any function define the domain and y-values define the range.

For x = 2,

f(2) = 3(2)³ = 24

For x = 5,

f(5) = 3(5)³ = 375

Therefore, range of the given function for the given domain will be {24, 375}.
