Answer:
a) 10*10 inch, b)yes, c) 15
Step-by-step explanation:
a)
we need to calculate the Greatest Common Factor between 30 and 50
then, the square tiles will be 10 inch *10 inch
b) it will change because they don't need to have the largest slab possible so they will use any other comon factor with a size they consider correct for the cheese.
c)
15 squares of 10inch*10inch of cheese could be cut.
The image of triangle CDE after a rotation of 90º counterclockwise around the origin is graphed at the end of the answer.
<h3>What is a rotation?</h3>When a polygon undergoes a rotation, this rotation is over an angle measure, that defines the coordinate rule for each vertex of the polygon.
For triangle CDE, the vertices are given as follows:
D(-7,-1), C(-7,-7), E(-4,-8).
The rule for a rotation of 90º counterclockwise around the origin, for each vertex (x,y) of the polygon, is given by:
(x,y) -> (-y,x).
Hence, applying the rule above, the vertices of the image of triangle CDE will be given as follows:
D'(1,-7), C'(7,-7), E'(8,-4).
The triangle, with these vertices labeled, is graphed at the end of the answer.
