1 day=24_h_
1 hrs=60mins
1 day =(60x24)mins= 1440mins
So,℅of 18mins in day
18/1440x100=1.25
18 minutes is 1.25% of one day.
75% 18/24 x 100 = 75
18 percent of 20000 is 3600.
We know that 18 percent of 100 is 18, and if you divide 5,000 by 100 you get 50. So multiply 18 x 50...So, 18 percent of 5000 = 900 We know that 18 percent of 100 is 18, and if you divide 5,000 by 100 you get 50. So multiply 18 x 50...So, 18 percent of 5000 = 900
23.2 percent of 18 900 is 4384.8.
18 percent of 65000 = 1170018% of 65000= 18% * 65000= 0.18 * 65000= 11700
18 minutes equates to 1.25% of one day.
A. 16 of 18 percent and 2 of 9 percent b. 14 of 18 percent and 4 of 9 percent c. 16 of 9 percent and 2 of 18 percent d. 14 of 9 percent and 4 of 18 percent
600ml.
18 minutes
It is 18/180 times 100 = 10%
18% of 330 = 59.4 So there are 59.3ml of pure acid in 330ml of 18% acid solution.
One day is equal to 60 x 24 = 1440 minutes. Therefore, 18 days is equal to 18 x 1440 = 25920 minutes.
75% 18/24 x 100 = 75
It is: 80/(24*60) = 1/18 of a day
The total volume of solution equals 18 L. So if we let X be the 50% solution & Y be the 20% solution we can solve a set of two equations with 2 unknowns: X + Y = 18 (total volume of solution is 18 L) 0.5X + 0.2Y = 18*(0.30) (the total amount of alcohol in the new 18L solution) Solving simultaneously, multiply the 1st equation by 0.5 then substract to solve for Y. X + Y = 18 {*0.5} => 0.5X + 0.5Y = 9 0.5X + 0.2Y = 5.4 => 0.5X + 0.2Y = 5.4 ------------------------------------------------------- 0.3Y = 3.6 Y = 12 Then substitute for Y back into the 1st equation & solve to get X=6. So you need 12 L of the 20% solution & 6 L of the 50% solutions to mix together to get 18 L of a 30% alcohol solution.
The answer is 8 g NaCl.
60% solution contains 6/10 x 30 ie 18 litres 18 + A = 3/4 (30 + A) 72 + 4A = 90 + 3A 4A - 3A = 90 - 72 A = 18 ie add another 18 litres, giving 36 litres out of 48 which is the required 75%.
