Considering that the shaded area is the part of the semi circle outside the triangle:
Area of circle= Pi x radius2 (this means radius squared)
Area of triangle= 1/2 x base x height
1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17
127.17 - (1/2 x 18 x 9) = 46.17cmsquared
Answer:
300
Step-by-step explanation:
10% of 250 is 25. so 20% is 50
250 + 50 = 300
Answer:
y intercept equals 1
Step-by-step explanation:
y= -1/2x+1
the slope is -1/2
the y intercept is 1
Answer:
no solution
Step-by-step explanation:
5d - 8 = 1 + 5d
Add 9 to both sides
5d = 9 + 5d
Subtract 5d
0 does not equal 9
No solutions
I believe that’s false, because for every x there should only be one y, and x(5) has two y’s (1 and 3)
