First, pretend the semicircle isn't cut out of the triangle and find the area of that equilateral triangle using the equation:
where l=the length of one side of the triangle (2+2+4=8mm).
Then find the area of the semicircle using the equation for the area of a circle:
where r=the radius of the circle (4/2=2mm) and then dividing the area you get by 2 to get the area of the semicircle.
Finally subtract the area you got for semicircle from the area of the entire equilateral triangle.
If you use the inverse operation that it subtraction so 12 minus 4 is 8 so if u substitute 8 for x, 8 + 4 is 12
I think the equation would be y=32000(1/2x). The y intercept would be, (16000 , 1) (8000 , 2) (4000 , 3).
Answer:
Peter's number is 36.
Step-by-step explanation:
If you subtratct 13 from 36, you get 23.
If you multiply that times -3, you get -69.
(The way I got 23 was by dividing -69 and -3)
I hope this helped you even though it's late.
