Answer: False.
Step-by-step explanation:
There does not exist a "quarter circle" as a circle with a radius of 4 units, the only notable circle that does exist is the unit circle, that is the circle where the radius is equal to 1, represented by the equatin x^2 + y^2 = 1
The term "quarter circle" actually does refer to a fourth part of a circle, not to a circle of radius 4.
So the statement is false
The three rugs will cover an area of 108π square feet.
Step-by-step explanation:
Given,
Radius of each rug = 6 feet
Number of rugs bought = 3
As the rugs are circular;
Area covered by each rug = πr²
Area covered by each rug = 
Area covered by each rug = 
Area covered by each rug = 36π square feet
Area covered by 3 rugs = 36π*3 = 108π square feet
The three rugs will cover an area of 108π square feet.

Answer:
This equation has ONE unique solution, which is x = 1.
Step-by-step explanation:
Let's actually solve this equation, 0.9x+5.1x-7=2(2.5x-3).
Mult. all four terms by 10 to eliminate the fractions:
9x+51x-70=2(25x-30)
Perform the indicated multiplication:
9x+51x-70= 50x - 60
Combine like terms: 60x - 70 = 50x - 60 => 10x = 10, and x = 1
This equation has ONE unique solution, which is x = 1.
