Answer:
Only the first graph with equation,
y = 11.5x
shows a proportional relationship between x and y.
Step-by-step explanation:
Only the first graph with equation,
y = 11.5x
shows a proportional relationship between x and y.
We know that y is proportional to x , written as,
y ∝ x
only when, y =
where k ≠ 0

Answer:
<em>82.67% of the fertilizer will be used on the property.</em>
Step-by-step explanation:
<u>Area of Plane Figures</u>
The backyard described in the problem has two parts: One with a rectangular shape of 30 feet by 20 feet. The other with a triangular shape with a base of 24 feet and a height of 12 feet.
The area of a rectangle is calculated by:
![A_r=L*W](https://tex.z-dn.net/?f=A_r%3DL%2AW)
And the area of a triangle is:
![\displaystyle A_t=\frac{B*H}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A_t%3D%5Cfrac%7BB%2AH%7D%7B2%7D)
All the backyard will be covered by fertilizer coming from a container with a capacity of 900 square feet.
The total area of the backyard is the sum of the area of the rectangle Ar and the area of the triangle At as follows:
![A_r=30*20=600\ ft^2](https://tex.z-dn.net/?f=A_r%3D30%2A20%3D600%5C%20ft%5E2)
![\displaystyle A_t=\frac{24*12}{2}=144\ ft^2](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A_t%3D%5Cfrac%7B24%2A12%7D%7B2%7D%3D144%5C%20ft%5E2)
The total area of the backyard is:
![A=600\ ft^2+144\ ft^2=744\ ft^2](https://tex.z-dn.net/?f=A%3D600%5C%20ft%5E2%2B144%5C%20ft%5E2%3D744%5C%20ft%5E2)
To find the percentage of the container, we calculate:
![\displaystyle \frac{744}{900}*100\%=82.67\%](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B744%7D%7B900%7D%2A100%5C%25%3D82.67%5C%25)
82.67% of the fertilizer will be used on the property.
