The question has missing details
The m<em>issing options are: </em>
<em>A. 188,000 square yards </em>
<em>B. 138,000 square yards </em>
<em>C. 600 square yards </em>
<em>D. 300 square yards</em>
<em>See attachment 1 for the missing diagram</em>
Answer:
<em>B. 138,000 square yards </em>
Step-by-step explanation:
The figure can be divided into two shapes (see attachment 2)
From attachment 2,
The dimension of the big rectangle is 1300ft by 800ft
The dimension of the small rectangle is 500ft by 400ft
So, the area is:
Area of the big rectangle added to the area of the small rectangle
i.e.
Convert to by dividing by 9
<em>From the list of given options, the closest to the area of the diagram is </em>
<em>B. 138,000 square yards </em>

All triangles are 30-60-90, therefore the short legs (2) are half as much as the hypotenuse. Therefore the hypotenuse is 4. Because its a rhombus, all sides are congruent, so you have the length and width and can multiply them to get 16 square units.
Answer:
The constant of proportionality is
Step-by-step explanation:
The constant of proportionality is the ratio between two directly proportional quantities
- If x and y are in directly proportion, then
, where k is the constant of proportionality.
- The direct proportion can be represented by a line whose equation is y = kx, where k is the slope of the line.
<em>To find the constant of proportionality from the given graph choose a point on the line and substitute x and y in the equation of the proportionality by the coordinates of the point.</em>
∵ Point (4, 18) lies on the line
∴ x = 4, y = 18
∵ The equation is y = kx
→ Substitute x by 4 and y by 18
∴ 18 = k(4)
∴ 18 = 4k
→ Divide both sides by 4 to find k
∴
∴
→ Simplify the fraction by dividing up and down by 2
∴
∴ The constant of proportionality is
