The irrigation design for a new backyard is shown with four sprinkler heads and two walkways. The distance between grid lines is 3 feet.
4 sprinklers are on 2 separate pieces of land. Each sprinkler waters a circular area with a diameter of 9 feet. The sprinklers are at least 6 feet from each other. The sprinklers are more than 3 feet away from the walkway.

Which statements about the design are true? Select three options.

Each sprinkler head is placed more than 3 feet from the walkway.
If two additional sprinkler heads are placed on the lawn, every square foot of the yard would be watered.
The total area watered by each sprinkler is approximately 63.6 square feet.
The total area watered by all the sprinklers is approximately 254 square feet.
If the sprinklers were placed in two straight lines on the yard, they would water a greater amount of the lawn.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
