Answer:
19. C
20. D
21. B
22. A
Step-by-step explanation:
If an angle is subtended from an arc and it goes to the opposite end of the circle, the angle is HALF of the measure of the arc. If it goes to the center, it is SAME measure as arc.
19.
Arc BC is DOUBLE of Angle BAC, so
78 * 2 = 156
Answer is C
20.
Arc BEC is DOUBLE of Angle BAC, so
114 * 2 = 228
Answer is D
21.
Angle ABC is HALF of Arc AC, so
Angle ABC = 110/2 = 55
Answer is B
22.
Angle ABC is HALF of Arc AC, so
Angle ABC = 218/2 = 109
Answer is A
This answer is most likely wrong, but this is what I had gotten.
Using the formula BxH divided by 2, I came up with an answer of 108.
Answer:
D
Step-by-step explanation:
A proportional relationship is defined by a linear equation whose y-intercept is zero.
Thus, we immediately reject answers A, B, and C because all involve a non-zero y-intercept.
D is the correct answer. We combine the unit cost $1.75/lb with the shipping fee $0.16/lb, obtaining a unit cost of $1.91/lb. The desired linear equation with zero y-intercept is then
C(x) = ($1.91/lb)x, where x is the number of pounds of avocados sold.
