To calculate the percentage of 18 minutes in a day, you first need to convert 1 day into minutes. There are 24 hours in a day, and each hour has 60 minutes, so 1 day is equal to 24 x 60 = 1440 minutes. Next, you divide 18 minutes by 1440 minutes and multiply by 100 to get the percentage. Therefore, 18 minutes is 1.25% of 1 day.
75% 18/24 x 100 = 75
To calculate the percentage of 18 minutes in 1 hour, we first convert both time values to the same unit, such as minutes. Since 1 hour is equal to 60 minutes, we can set up a proportion: 18 minutes is to 60 minutes as x percent is to 100 percent. Solving for x, we find that 18 minutes is 30% of 1 hour.
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 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
To determine the amount of 18% solution to add: Let x = volume of 18% solution to be added. 0.18x + 0.10(360) = 0.15(x + 360) Solving for x, you would need to add 75 ml of the 18% solution to the 360 ml of 10% solution to obtain a 15% solution.
18 minutes
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.
18 hours 10 minutes
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%.
