Circumference = [answer1] (Round to the nearest tenth, if necessary.  Use 3.14 for pi.)

Find the scale factor for the dilation shown. Enter any fractions as a/b. A coordinate plane shows two parallelograms, one large in black and one smaller in red. The black parallelogram has vertices A at (−9, -2), D at (3, -2), E at (9, 6), and M at (−3, 6), with horizontal top and bottom sides. The red parallelogram lies inside the black one, with vertices A′ at (−3, -1), D′ at (1, -1), E′ at (3, 2), and M′ at (−1, 2).

Find the value of x. x = [answer1]  Two parallel diagonal lines are marked with matching arrow indicators, showing they run in the same direction. A transversal line intersects them at points T (left intersection) and B (right intersection). The transversal, also labeleld with a cursive lowercase l, extends from point V on the left through T and B to point C on the right. The leftmost parallel line, also labeled with a cursive lowercase m, extends from point S at the top through T to point U at the bottom, while the rightmost parallel line, also labeled with a cursive lowercase n, extends from point A at the top through B to point D at the bottom. The intersections form multiple angles where angle ABC is labeled (6x+10)° and angle UTV is labeled 118°.

On the night of elections, polls are showing that a Joe Black currently has 48% of the votes for senate, while his opponent Kimberly Monk has 53% of the votes. The margin of error is . Who is currently winning the race? 

Find the coordinates for the dilation of the figure shown if the scale factor is 2. : [answer1] : [answer2] : [answer3] A coordinate plane shows a triangle with vertices labeled A, B, and C. Point B is on the left at (−5, −3), and point C is on the right at (5, −3), forming a horizontal base below the x-axis. Point A is above the x-axis at (1, 2).

Marine biologists are studying the viperfish. They’ve found five viperfish living within 20 miles of the coast of Maine. If the coast of Maine is 228 miles long, about how many viperfish can they expect to live along the coast of Maine?  [answer1] viperfish

Find the scale factor for the dilation shown. A coordinate plane shows two diamond-shaped quadrilaterals (rotated squares), one smaller in black and one larger in red. The black figure has vertices P at (2, 0), L at (4, −2), R at (2, −4), and U at (0, −2). The red figure has corresponding vertices P′ at (4, 0), L′ at (8, −4), R′ at (4, −8), and U′ at (0, −4).

Which histogram corresponds to the data from Mrs. Jones’ math test scores shown? 82, 75, 90, 92, 97, 86, 79, 61, 67, 81, 84, 76, 77, 81, 60, 69, 77, 88, 82, 81, 82, 91, 98, 71, 76, 90, 89, 82, and 92

Biologists studying gray wolves have found that 4 out of every 20 wolves tagged weigh 115 pounds. If the population of wolves in the area they’re studying is 180 wolves, about how many do they expect to weigh 115 pounds?  [answer1] wolves

  If A geometric diagram shows two large triangles. The upper triangle has vertices labeled A at the top left, B at the bottom left, and C at the top right. The lower triangle has vertices labeled F at the bottom left, D at the bottom right, and E at the top right. The slanted sides of the triangles run parallel to each other. The vertical sides on the left and right edges appear straight, with A above B on the left and E above D on the right.
