Thomas used 25 square tiles to cover a patio with an area of 75 square feet. paul used 20 square tiles to cover a patio with an area of 100 square feet. sarah used 30 square tiles to cover a patio with an area of 120 square feet. who used the square tile with the greatest side length, and what was its side length to the nearest hundredth ?

Paul used the square tile with the greatest side length. Its side length (to the nearest hundredth) was

Step-by-step explanation:

The side lenght "s" of a square can be calculated with this formula:

Where  "A" is the area.

We know that Thomas used 25 square tiles to cover a patio with an area of 75 square feet, then, the area of each 1 tile was:

Its side lenght, rounded to the nearest hundreth,was:

Paul used 20 square tiles to cover a patio with an area of 100 square feet, then, the area of each 1 tile was:

Its side lenght, rounded to the nearest hundreth,was:

Sarah used 30 square tiles to cover a patio with an area of 120 square feet, then, the area of each 1 tile was:

Its side lenght, rounded to the nearest hundreth,was:

Therefore, Paul used the square tile with the greatest side length. Its side length (to the nearest hundredth) was

tangent

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
