2) mr. somers had twenty pieces of metal that were all the same length. if each piece of metal was 3 1/5 inches long and he put them side by side, what would be the total length of all the pieces together?

You would do 20 • 3=60 and the you would add 20 • 1/5=4 so, your total is 64in.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
