The gear on the right is the driving gear. If the driving gear moves at 100 RPM and the diameter of the wheel attached to the
driven gear is 2.75 in, how far in feet will the robot move in 2 minutes? How long in
seconds will it take to travel 100 feet?

the answer is c. 23/3

g

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
