Ella threw 5 grams of salt into 20 grams of water. She made _ grams of _% salt solution.

1 answer:

7 0

When we make a solution, the solute doesn't go away. All the solute we use stays in the solution it only dissolve in the solution.

The total mass of solution is always equal to the mass of solvent added to the mass of solute.

Therefore 5gram + 20 gram = 25 gram of solution.

5/25×100= 20%

What is the rate of change of the function

masya89 [10]

Answer:

The rate of function is: 5/2

Step-by-step explanation:

As we know that the rate of change of a function is a ratio that compares the difference between the output values to the difference between the corresponding input values

rate of change = change in y-values / change in y-values

So, all we need is to find the slope between any two points as the slope is basically termed as the rate of change.

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$
