ANSWER

The correct answer is A.

EXPLANATION

If you know the diagonals of a kite you can easily find the area.

The area of a kite is half the product of the diagonals.

From the graph, the from -5 to 4.

Using the number line approach. The longer diagonal is

|4 -  - 5|  =  |4 + 5|  =  |9|  = 9 \:  \: units

Similarly the shorter diagonal is from -4 to 4

|4 -  - 4|  =  |4 + 4|  =  |8|  = 8 \:  \: units

The area of the kite is:

Area= \frac{1}{2}  \times 8 \times 9

Area=4 \times 9

This implies that

Area=36 \: square \:  \: units

The first choice is correct.

Step-by-step answer:

Area of a kite is half of the product of the diagonals.

The length of diagonal in the x-direction is 4+5 = 9

The length of diagonal in the y-direction is 4+4 = 8

Therefore

Area of kite = 8*9/2 = 36 units.

The judges at the track meet will award prizes to the top 4 teams. How many different ways can the top four teams place??
Nata [24]
They could give to teams more than likely on an average score the whole team has done, or at least that is what they are supposed to do. but they also might award the team which had more teammates get better places. for example if party place got three people on their team but they all did 3rd then boring barn who got 1 person could possibly win if that one person gets 1st place.
