answer: The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first:  19/38, since 19 is the size of the model's length and 38 is the real length.  For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:

19*x = 38*18

19x = 684

The last year the price was $650700.

Amount increase in the price is $(750900 - 650700) = $100200.

WILL AWARD BRAINIEST: Find the area of the shaded polygons below:
IRINA_888 [86]

Answer:

<h2>9 square units</h2>

Step-by-step explanation:

You can use the Pick's formula:

A=i+\dfrac{b}{2}-1

Where

i - the number of lattice points inside the polygon

b - number of lattice points on the border located on the perimeter of the polygon

From the picture we have:

i=5\\\\b=10

Substitute:

A=5+\dfrac{1}{2}\cdot10-1=5+5-1=10-1=9
