How would Judy determine the constant of proportionality given that y = kx, where x represents a person’s weight on Earth, y represents a person’s weight on the Moon, and k is the constant of proportionality?

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

answer: do we write it
