9x = 63
x = 7
Cole put seven books on each shelf.
Answer:
17.4456 Pretty sure they want you to round up not sure
Step-by-step explanation:
I like to divide by 100 the get the rate for 1% and then multiply by the actual number in your case 9 you can use a calculator for this to make it easy and you can get it pretty simple this usually works for all percent's if you have multiple like 9.74 use the lowest percent .04 that way you can use it to find the rest I hope this helps :) lmk if you want me to explain more
In fact, this problem belongs to the chemistry section. Recall that many other sciences require mathematical calculations. The problem will belong to Mathematics only if no knowledge of other sciences are required to solve the problem.
Solubility for the given substances is measured in grams per 100 g of water at a particular temperature (20 deg.C).
This means that the mass (assumed to be the solute) will not change the solubility, just the minimum quantity of solvent (water) will.
Thus the solubility of sodium chloride will remain L=36 g/100g H2O for any quantity of solute. Similarly, the solubility of lead nitrate will remain as K=54 g/100 g H2O.
The reason that they remain constant is because the quantity of solvent (water) is fixed at 100 g. Varying amount of solute will affect the quantity of solvent required, but not the solubility.
I'll leave it to you to calculate the difference between K & L.
Provide electricty is the answer because if you use elec
A change from 26 to 36 represents a positive change (increase) of 38.46153846153847%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = [(26 - 36) / 26] x 100 = 38.46153846153847 % (increase)
Where: 26 is the old value and 36 is the new value. In this case we have a positive change (increase) of 38.46153846153847 percent because the new value is greater than the old value. So this is rounding to 38.4!
