Answer:   89.6 kg of water

Step-by-step explanation:

Find the total volume of the tank:

(80cm)*(35cm)*(40cm) = 112,000 cm^3

4/5 of this would be 89,600 cm^3

Water has a mass of 1 gram/cm^3

(1 gram/cm^3)*(89,600 cm^3) = 89,600 g of water

(89,600 g)*(1 kg/1,000 g) = 89.6 kg of water

galben [10]
So we are finding the difference btween 5x-3 and 3x+1.
(5x-3)-(3x+1)

Let's subtract the x's first.
5x-3x=2x
Now the numbers.
-3-1=-4
Now, we need to put 2x and -4 together. 

The expression would be 2x-4.

When compared with the independent variable, how many of the graphs represent a linear relationship?
strojnjashka [21]
Since a slope differe, this is not linear relationship. Simply, if you connect all points on the graph, they will not lie on the same line. Two next graphs represent the linear relationships, so they represent the linear relationship.
