The answer is the graph b.
The mass of the solution is 190 g - 120 g = 70 g. Thus, it's density is 70 g / 50 mL = 1.4 g/mL.
The rotation that that translates AWXY to AW'X'Y' is a 45° anticlockwise rotation. See the attached image for details.
<h3>What is a rotation in math?</h3>
Rotation in math refers to the change in the angle of a geometric shape around a central axis on a point on the geometric plane such that it's original coordinates are modified but it's size or shape.
Hence, it is correct to state that The rotation that that translates AWXY to AW'X'Y' is a 45° anticlockwise rotation.

Answer:
Mid point is: (2.8;4.9)
Step-by-step explanation:
To find midpoint of a line segment we can use the general equation:
![Mid=\frac{x_1+x_2}{2} ;\frac{y_1+y_2}{2}](https://tex.z-dn.net/?f=Mid%3D%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%20%3B%5Cfrac%7By_1%2By_2%7D%7B2%7D)
Where the point of the line are: (x₁;y₁) and (x₂;y₂).
In the problem, x₁ = 2.6, y₁ = 5.1 and x₂ = 3 and y₂ = 4.7. Replacing in the equation:
![Mid=\frac{2.6+3}{2} ;\frac{5.1+4.7}{2}](https://tex.z-dn.net/?f=Mid%3D%5Cfrac%7B2.6%2B3%7D%7B2%7D%20%3B%5Cfrac%7B5.1%2B4.7%7D%7B2%7D)
