Answer:
Step-by-step explanation:

The fraction is 31/100, the decimal is 0.31 which means your simplest form is 31/100
Answer:
2x in common (slope)
Step-by-step explanation:
similar because they both have a slope of 2
different because the 2nd equation has a y intercept of 3
Answer:
Yes
Step-by-step explanation:
To see is (2, 6) is a system, we can plug it into the system to check if it gives us true statements:
6 = -2+8
6 = 6
6 = 5(2)-4
6 = 10-4
6 = 6
Both of the equations are true, therefore (2, 6) is a solution to this system.
The area of a sector of a circles is calculated by the equation A = πr^2 (theta/360). From the data of the sector, we determine the radius of the circle. THen, we can calculate for the area of the circle.
16.4π = πr^2 (72/360)
r = 9.06
Area of circle = πr^2
Area of circle = π(9.06)^2
Area of circle = 82π
