The 6 R's in textiles/sustainability are:
- Recycle
- Refuse
- Reduce
- Reuse
- Repair
- Rethink
These are used for product analysis, after the product has been designed, to see how eco' friendly it is. To make sure if it is safe for the Earth and ozone layer.

How many gallons of water in a cylinder 6' round and 125' high?
The volume of a cylinder is calculated using the formula V = πr^2h, where r is the radius and h is the height. The radius of a cylinder with a diameter of 6' is 3'. Thus, the volume of the cylinder is approximately 3390 cubic feet. There are about 7.48 gallons in a cubic foot, so the total volume is equivalent to about 25,379 gallons of water.
What is the size of the nucleus having mass number 216?
R=RoA1/3 where Ro = 1.2 fm and A= mass no.So R= 1.2 (216)1/3 = 1.2 X 6 = 7.2 femtometers or 7.2 X 10-15 m
What are the effects of refrigerator and air conditioner on ozone layer?
CFCs, and are known ozone depleters. See the link below for what their effects are.: * Refrigerant R-10 is CCl4. * Refrigerant R-11 is CCl3F. * Refrigerant R-12 is CCl2F2. * Refrigerant R-13 is CClF3. HCFCs, and are known ozone depleters but with lowered suvivability to reach the ozone layer. See the link below for what its effects are. * Refrigerant R-22 is HCClF2. * Refrigerant R-40 is CH3Cl. It is responsible for ~17% of chlorine-assisted ozone destruction in the statosphere. It is today primarily produced by plants, and the combustion of organic waste materials, since its use in industry was stopped some time ago. CFCs inclusive of HCFCs, are ~82% of the chlorine currently found in the stratosphere Some refrigerants that do not contain chlorine or bromine are: R-14, R-23, R-32, R-41, R-50, R-116, R-125, R-E125, R-134, R-134a, R-E134, R-143, R-143a, R-143m, R-E143a, R-152, R-152a, R-161, R-170, R-218, R-227ca, R-227ca2, R-227ea, R-227me, R-236cb, R-236ea, R-236fa, R-236me, R-FE-36, R-245ca, R-245cb, R-245ea, R-245eb, R-245fa, R-245mc, R-245mf, R-245qc, R-254cb, R-254pc, R-263, R-272, R-281, R-290, R-C318, R-3-1-10, R-347mcc, R-347mmy, R-365mfc, a few of the blends between R-400 and R-600, R-600, R-600a, R-601, R-601a, R-610, R-611, R-630, R-631, R-702, R-704, R-717, R-718, R-720, R-728, R-732, R-740, R-744, R-744A, R-764, R-784, R-1114, R-1132, R-1141, R-1150, R-1216, R-1270 This list includes chemicals that are so stable that they also can accumulate over decades as CFCs did, and yet new problems may result from their use and/or release into the environment. Others of them are fuels (so are flammable), components of natural gas, and may not accumulate, but can contribute to ozone pollution as a VOC.
What refrigerants has the lowest boiling temperatures at atmospheric pressure R-12 R-22 R-134a R-502?
This is R-502 with a boiling point at -45 0C.
How do you convert primary alcohol to secondary alcohol?
R-choh-ch3 +h2so4 -> R-ch=ch2 R-ch=ch2 + HBr -> R-ch2-ch2Br R-ch2-ch2Br + H2O -> R-ch2-ch2oh + HBr
Dorothy is 6 years older than Ricardo The product of their present ages is twice what the product of their ages was 6 years ago How old is Dorothy?
d = r + 6 now you make the equation relating what happened 6 yrs ago, remembering that then they were r-6 and d-6: dr = 2(r-6)(d-6) plug the first eqn into the second one and solve: r(r+6) = 2(r-6)(r) you can cancel an r, since r isn't 0! r+6 = 2(r-6) r=18 So Ricardo is 18 and his sis is 24.
What is r x 6 if r9?
If r=9, then r*6 would be 9*6, or 54.
What is the answer to 1-r equals -5?
6
R 9 - 6 equals 12 what is r?
r9 - 6 = 12 then r is 2
What is the square root of 6 times the square root of 10?
r=square root sign. r(6)*r(10)=r(6*10)=r(60)=2r(15)
What is equivalent to 1 to 6?
1 to 6 = 2 to 12
A+5+R-6?
a+r-1
What is the radius of a circle if the circumference is 6 inches?
Circumference is equal to 2(pi)r. So if C = 6, and 2(3.14)r = C, then solve for r r= 6/2(3.14) = .955
Can rxr plus 7r plus 6 be factored?
I think so.r2 + 7r + 6 = [ (r+6) (r+1) ]
What are the 6 R's in one direction?
LouisBest Answer louis was prank calling 118 and they asked him for an adress and he was spelling terrence Lou: T E R R R R R R 118: how many R's are there? Lou: Err, 6!
What is the quotient of 45 and r?
45/r
What is the answer to 4x plus 8 equals 2r plus 20?
That depends on what the question is. What you gave is simply a relationship between two variables. You can simplify it like this: 4x + 8 = 2r + 20 (4x + 8) / 2 = (2r + 20) / 2 2x + 4 = r + 10 2x + 4 - 4 = r + 10 - 4 2x = r + 6 You can then solve for x by dividing both sides by two: 2x / 2 = (r + 6) / 2 x = r/2 + 3 You could also solve for r by subtracting six from both sides, and rearranging the equation: 2x = r + 6 2x - 6 = r + 6 - 6 2x - 6 = r r = 2x - 6 r = 2(x - 3)
