Jeff Friedman was a section chief for an electric utility company. After the numbers in one of his reports to the management of the utility didn't add up, he was reassigned to the home economics department. He interviewed 131 people in a suburban shopping center to discover some of their cooking habits. He obtained the results shown to the right. 52 use microwave ovens; 69 use electric ranges; 52 use gas ranges; 19 use microwave ovens and electric ranges; 21 use microwave ovens and gas ranges; 3 use both gas and electric ranges; 1 uses all three; 2 uses none of the three. Should he be reassigned one more time? Why or why not?

answer: it is 1: 47 pm

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
