What are multiples of 11 and 44?
Numbers that both 44 and 11 divide evenly into. Since 44 is a multiple of 11, then all multiples of 44 are also multiples of 11. 44, 2x44, 3x44 etc 44, 88, 132 etc
What two simpler problems can you use to find 4x22?
Two simpler problems? It's not clear what this means.Maybe 2x44 or 8x11? - but they're not really simpler.Maybe (2x2)(2x11), but that doesn't get you closer to the answer.Maybe 4x20=80, 4x2=8 and 80+8=88 - but that's 3 simpler problems.If this is not your question, please clarify and ask the question again. :-)
The burning of fuel such as propane releases?
The formula for the combustion of propane is: C2H6 + 5O2 --> 2CO2 + 3H2O So each mole of propane creates two moles of carbon dioxide. One mole of propane is 30 g, one mole of carbon dioxide is 44 g So each gram of propane creates (2x44)/30)= 2.93 g of carbon dioxide on combustion. In common terms a 20lb tank of p for a BBQ creates a bit less than 60 lb of carbon dioxide
How do you show your work for the greatest common factor of 18 and 30?
You can not find the greatest common factor for just one number. Ill will choose another number to compare 33 with. Lets choose 88.First take 33 and find all the numbers it divides into by a whole number33/3 = 11 So 3 and 1133/33 = 1 So 1 and 33the only factors are 3 and 11 ... 3x11=33and 1 and 33 ... 1x33=33it is written like this...33 - 1,3,11,33Now take 88 and find all the numbers that it divides into by a whole number88/2 = 44 So 2 and 4488/4 = 22 So 4 and 2288/8 = 11 So 8 and 1188/88 = 1 So 1 and 88So the factors of 88 are ... 2x44=88 ; 4x22=88 ; 8x11=88 ; 1x88=88it is written like this88 - 1, 2, 4, 8, 11, 22, 44, 88Now take all of the factors of 33 and 88 and find the number that is in common and that is the greatest. Did you find it...the answer is 11
How do you create drywall arch?
Personally I would get out my trammel points: these are devices that make any 3/4 x 3/4 stick of wood into a giant compass and have clamps on them and a place to put a pencil, or just get a straight piece of 3/4" stock and drive a nail in one end and a hole in the other end that would accommodate a #2 pencil, or just the point and secure it with tape at the radius you would like the arch to be, lets say 4'-0"=48". Assuming your arch is going in a non bearing wall, you will need to open the wall up to 52". Why 52 you ask? well you will have to add one jack stud to either side of your opening, that equals 3" and if you use 1/2" drywall that equals 1" on both sides, and that is 4" plus 48" equals 52". You might have to add additional king studs after you open the wall because even though the studs may be centered on 16" that will only give you 48" on center, and if you're demo-ing a door you will have to remove the existing jack, king studs and header. Find some new header material that will handle your 49" radius, 2x10, 2x12, or plywood laminated to equal 3 1/2" to equal the width of the existing framing, you can rip a 2x4 to make 2 1/2' spacers plus 1" of plywood equals 3 1/2 wall. Why 49", because the 1/2" drywall x 2 equals 1" - equals 48", at the sides anyway. Take your trammel points, or your straight stock with pencil and measure 49" between the two and make your radius mark. Make sure you have enough plywood on top of your arch so that it matches any height openings in the room. The gross length of the plywood will be 51" so that the plywood and 2x44 template will sit on the jack studs. screw the 2 pieces of ply together and cut out with your jig saw, Sabre saw or saws-all. Lay out the spacers on 16" centers and screw them to one piece of plywood. Flip the plywood over and screw it to the spacers making sure you line up all the straight and square edges. When you finish this round header don't install it right away. Turn it upside down and take a 3 1/2" strip of 1/2, or 1/4 (but why spend $14.00 for a 3 1/2" of drywall) and after wetting it on both sides slowly and I mean slowly let it drape itself into the mold you have made. You might have to wet it twice or three times or put a LITTLE weight on it to conform to the mold. Mr. gravity will help you in this endeavor, as opposed to nailing the plywood in place on the wall and trying to get wet drywall to stick over your head. Install the finished header with the drywall in place, come back with your 1/2" drywall on one side, trim to the curve and rock the other side and trim. It's better if your joints are a stud away from the opening rather than at the jack stud, or the immediate king stud Personally I would get out my trammel points: these are devices that make any 3/4 x 3/4 stick of wood into a giant compass and have clamps on them and a place to put a pencil, or just get a straight piece of 3/4" stock and drive a nail in one end and a hole in the other end that would accommodate a #2 pencil, or just the point and secure it with tape at the radius you would like the arch to be, lets say 4'-0"=48".
