Two painters stand on the board; one weighs 158 lbs and stands 4 ft, 11 in (c) from the left end of the board. Where must the 222 lbs painter stand so that each support carries the same weight? (express your distance in feet from the right end of the board (d).)please help!! thanks(:: Total weight = 222 + 158 + 84 = 464 lb So, each support must carry 232 lbs Working in inches: Take moment about Right hand end Board is assumed to be uniform - CG is at the center (232 x 32) + (232 x 133) = (158 x 106) + ( 84 x 82.5 ) +(222 x d)7424 + 30856 = 16748 + 6930 + 222d 222d = 14602 d = 65.77 inches Distance of 222 lb painter should be 5ft 5.77inches from Right end

Q: I am currently taking early childhood care education as my college major. I am learning about ZPD (Zone of Proximal Development), and scaffolding the the development in early childhood.How would you explain, and define scaffolding: Scaffolding basically means being the support (a scaffold is a support) in the child's learning. A preschooler can do a range of things. He or she will have mastered some things already and there will also be things that are beyond what he or she can do. When playing with the preschooler, you want to make sure that what's going on falls in that range (zone of proximal development). Don't give him or her something that's too easy or too hard to do, but play games that make them think a little and use what he or she already knows to take it a bit further. I hope I'm not confusing you more. In one sentence..scaffolding is supporting the child in learning something new based on what they already can do or know.

Q: i have an interview tomorrow but have a scafold piercing in , its been in there for about 2/3 months nearly healed competely , how ling can i leave it out for , maybe 30-45 minutes? thanks: They take around 6-9 months to heal completely...you shouldn't be taking it out at all. I stupidly took mine out after 3 months to clean a bit behind the bar and the bar would never go back through the top hole. It hurt like crap and bled profusely if I tried to push it through.

Q: I got my scaffolding approximately about 7 weeks ago maybe just a lil over, I want to know when is a good time to change the bar/take it out, I am keeping up with cleaning it 2 to 3 times a day with the saline solution, even though, it only requires to be cleaned 1-2 times a day to be fair though: Scaffold piercings, being two cartilage piercings connected by a single bar, take six months for initial healing and twelve months for a fully healed tunnel of flesh to be formed. Don't change it yet, I assure you, you will regret it. Just be patient, keep on cleaning, cleaning, salt-soaking.
