(126)(1.3)=163.8
divide 163.8 by 450 = .364 which is the answer
4,500 has two significant figures.
A 4500 watt element can work on a 20 amp breaker, but it may occasionally trip if the total load on the circuit exceeds 20 amps. It is recommended to use a 4500 watt element with a 25 amp breaker to ensure consistent performance.
No, ammonium nitrate (not ammonia nitrate) is not used in the production of methamphetamine. The chemicals typically used in meth production include pseudoephedrine or ephedrine, along with other substances such as hydrochloric acid, red phosphorus, and lithium. Using ammonium nitrate for this purpose is not only illegal but also dangerous.
A gas flame in welding can reach temperatures ranging from 3,000°F to 6,300°F (1,649°C to 3,482°C) depending on the type of welding process and gases used. These high temperatures are necessary to melt and fuse metal together during the welding process.
Mercury (Hg)Historically, mercury was used extensively in hydraulic gold mining in order to help the gold to sink through the flowing water-gravel mixture. Thin mercury particles may form mercury-gold amalgam and therefore increase the gold recovery rates. Large scale use of mercury stopped in the 1960s. However, mercury is still used in small scale, often clandestine, gold prospection. Total use of mercury in placer mining in California has been estimated to more than 4500 tons (10,000,000 lbs). Mercury was also used in silver mining. And in the process of gilding (gold plating) silver plate.Cyanide (HCN)Cyanide solutions are used in the extraction of gold from low grade ore. The reaction in the Elsner Equation is as follows :4Au + 8NaCN + O2 + 2H2O -> 4NaAu(CN)2 + NaOHThe gold is then recovered from the the soluble aurocyanide complex by plating out.An Aside: Walking across tailings area you can smell the sweet cyanide aromaAqua Regia (HNO3 + HCl Solution)This is the historic method of dissolving gold . Higraders in gold camps ofhen are found by watching chimneys to see the brown nitrous fumes from boilling off the acid to recover the gold.
6% of 4500= 6% * 4500= 0.06 * 4500= 270
30% of 4500= 30% * 4500= 0.3 * 4500= 1350
21% of 4500= 21% * 4500= 0.21 * 4500= 945
36% of 4500= 36% * 4500= 0.36 * 4500= 1,620
5% of 4500 = 4500*5/100 = 225
4500 + 100% = 4500 + 4500 = 9000 dollars
2.5% of 4,500 = 2.5% * 4500 = 0.025 * 4500 = 112.5
um, about 4500
4500 = MMMMD
You need at least two numbers to find an LCM.
6.75 percent of 4500 = 303.75 6.75% of 4500 = 0.0675 * 4500 = 303.75
6% of $4,500.00= 6% * 4500= 0.06 * 4500= $270.00
