1) Circle A (because A is the center)

2) A minor arc is smaller than a semicircle so EF, CBF, and DEF

3) 180 = EAD + 90 + 52

180 = EAD + 142

38° = EAD

4) angle EAF = 180 - 60, or 120° so arc EF should be 120° (I believe)

5) arc FCE is opposite of EF so 360 - 120 = 240°

Robert can paint a room in 6 hours. Julio can paint a room in 8 hours.how long will it take for the two of them to paint a room

Llana [10]

Roberto paints 1/6 of a room in 1 hour.
Julio paints1/8 of a room in 1 hour.

Working together, they paint (1/6 + 1/8) = (4/24 + 3/24) = 7/24 room per hour.

The reciprocal unit rate is 24/7 hour per room = <em>3-3/7 hours</em> per room.
