Answer:
254/324 which is about 78.4%
Step-by-step explanation:
found area of entire square to be 18² or 324
found area of 4-quarter circles - which equals one circle with radius of 9
A = 81π which is about 70
subtracted 324 and 70 to get 254
ratio of shaded to unshaded is 254 : 324
Answer:
An angle measuring 100 degrees would be supplementary to any angle measuring 80 degrees, but it cannot be called supplementary by itself. "Complementary" and "supplementary" are terms that describe the relationship between two angles. They are comparative words like "larger."
Step-by-step explanation:
(0,1) is the y intercept because the point (0,1) lies on the y axis.
you would add 3y+5y and get 8y=-20
then the slope would be 8/1 and your y-intercept would be -20
27 divided by 3 (j) is 9. If j=3 then plug in 3 for the equation
