Answer:
Density is defined as:
Density = mass/volume.
We know that:
For liquid A:
Density = 70kg/m^3
Mass = 1400kg
Then the volume is:
Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3
For liquid B:
Density = 280 kg/m^3
Volume = 30m^3
We can find the mass of liquid B as:
mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg
We know that liquid C is a mixture of liquid A and B.
Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:
Mass of liquid C = 1400kg + 8400kg = 9800kg
The same happens for the volume, then:
Volume of liquid C = 30m^3 + 20m^3 = 50m^3
Then the density of liquid C is:
Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3
Answer:
The equation for the relationship is
.
Step-by-step explanation:
Given that point
is part of a direct relationship. That is:
![y \propto x](https://tex.z-dn.net/?f=y%20%5Cpropto%20x)
(1)
Where
is the proportionality constant.
If we know that
and
, then the proportionality constant is:
![k = \frac{y}{x}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7By%7D%7Bx%7D)
![k = \frac{21}{6}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B21%7D%7B6%7D)
![k = \frac{7}{2}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B7%7D%7B2%7D)
Lastly, the equation for the relationship is
.
