delete my answer please its useless
Well if you divide 12.05 by three you will get 4.01 pounds each
In this problem, you there are only 2 different sets of measurements.
Angles 1, 2, 7, 8 are all the 30 degree angles. They are alternating interior angles of parallel lines cut by transverals.
Angles 3, 4, 5, 6 would be 150 degrees, because they are supplementary (add to 180) with the adjacent angles.
X^2 + y^2 - 2x + 7y + 1 = 0
(x^2 - 2x) + (y^2 + 7y) + 1 = 0
(x^2 - 2x + 1) + (y^2 + 7y) + 1 = 0+1
(x^2 - 2x + 1) + (y^2 + 7y + 49/4) + 1 = 0+1+49/4
(x - 1)^2 + (y + 7/2)^2 + 1 = 0+1+49/4
(x - 1)^2 + (y + 7/2)^2 + 1-1 = 0+1+49/4-1
(x - 1)^2 + (y + 7/2)^2 = 49/4
(x - 1)^2 + (y + 7/2)^2 = (7/2)^2
The final answer is choice B
The answer is 122 it’s basically the same rounding with whole numbers
