When Georgie first bought his sailboat, it cost $15,200. He sold his sailboat fifteen years later for $12,160. Find the percent of decrease.

Identify the hypothesis and the conclusion for the following statement: If it rains, then I will have to take the bus to work.

. From this we can conclude that .  Triangle ACB has vertex A at the top, C at the bottom left, and B at the bottom right. A perpendicular segment AF is drawn from vertex A to base BC, forming a right angle at point F. Segments CE and BD are drawn from vertices C and B to sides AB and AC, respectively, intersecting at a point inside the triangle. Tick marks on segments CD and AD indicate they are congruent. Arcs mark angles ACE and BCE, highlighting angle relationships at vertex C.

Point Q“ is the image of point Q after a composition of transformations: a reflection over line m, followed by a reflection over line n. If m and n intersect to form a 44 degree angle, what is the angle of rotation from Q to Q“ about the point of intersection?

Suppose that triangle DEF can be generated from triangle ABC by some isometry. Also suppose that triangle XYZ can be generated from triangle DEF by some isometry.  From this we can conclude that .

The flight from New York City, New York and Seattle, Washington is 2, 410 miles. If the flight makes a stop in Boise, Idaho after 2, 160 miles, how far must it be from Boise, Idaho, to Seattle, Washington.

Equilateral triangle ABC has a perimeter of 72 centimeters. A perpendicular bisector is drawn from  to side  at point . What is the length of ?

The area of quadrilateral ABCD with coordinates A = (0,1) B = (2,4)  C= (6,0) D = (4,-3) is ______ square units.  Round to the nearest whole number.

The coordinates of quadrilateral ABCD are as follows: A=(3,0), B=(7,1), C=(6,-4) and D=(-2,-2). Find the coordinates of quadrilateral A’B’C’D’ which is the rotation of ABCD clockwise about the origin. Coordinates A’ ([ans0],[ans1]) B’ ([ans2],[ans3]) C’ ([ans4],[ans5]) D’ ([ans6],[ans7])

Use the figure to answer the questions below. Several rays intersect at point P, forming multiple angles. A horizontal line passes through P from point F on the left to point A on the right. A diagonal line passes through P from point B in the upper left to point T in the lower right. A nearly vertical line passes through P from point R above to point C below. The angle between rays PB and PR is labeled 38°, and the angle between rays PA and PT is labeled 40°. What is the value of ? [answer0] degrees Are and supplementary angles? Type yes or no. [answer1] Areand complementary angles? Type yes or no. [answer2] Is an acute, right, obtuse, or straight angle? [answer3] Is line segment PF an angle bisector of ? Type yes or no. [answer4]
