What is 250 percent of 1250?
NO such thing as 250% . 100% is totality!!!! However, 250 = 100 x 2.5 So multiply 1250 x 2.5 = 3125 The Answer!!!! NB It is a common mistake to say/write a percentage value greater than 100% . 100% is totality!!!!! What is meant is a value is multiplied by the increase.
What is the exact value of 275 and 250?
275 and 250 = 275 + 250 = 525 exactly.
How do you determine percentages greater than 100?
To determine percentages less than 100, multiply the number by x/100. The same holds for percentages over 100 - for example, finding 250 percent of a number is equivalent to multiplying the number by 250/100, that is, 2.5.
How can we convert 25 percent of ammonia solution to 10 M?
25% ammonia solution means 25g Ammonia in 100ml of water. To convert it into moles i.e for 1000ml solvent, 25x100=250 which means 250g of ammonia is present in 1000ml of water to make a 25%solution. To convert it into molar solution we will divide 250 by the molecular mass of ammonia i.e 17. 250/17= 14.71M This means that 25% ammonia solution contains 14.71 moles of ammonia. Now we will use the formula M1V1=M2V2 Let's say we want to make 10 molar solution in 500ml water. Then, M1=14.71 V1=? M2=10 V2=500 Putting values in the above equation: 14.71xV1 = 10x500 V1 = 10x500 / 14.71 = 340ml We will take 340ml of the 25% ammonia solution and make the volume up to 500ml with water. This will be our 10 molar solution of Ammonia.
A ski slope is 250 yards long with a vertical drop of 100 yardsfind the angle of depression of the slope?
The angle of depression is equal to the angle of elevation, so use the sine ratio to find the angle. sine = opposite (the vertical drop) divided by the hypotenuse (the ski slope) sine = 100/250 = 2/5 or 0.4 sine-1(0.4) = 23.57817848 degrees which is about 24 degrees
