Why are the atomic masses listed in the periodic table not whole numbers? Answer Scientists have yet to make the precise measurements. That would be too much of a coincidence. ??>>The atomic masses are average atomic masses. or >>Today's instruments are able to...
How would you classify the following material?swimming pool water homogeneous mixture<<< heterogeneous mixture a pure element a pure compound depends on how many children have been in it
If it is 1/(a-y) = 1/y then cross multiply to get y = a -y solve for y in terms of a.
pace is 400 meters/48 seconds You could use a proportion; 400/48 = x/192
Are you just taking the square root of the x? If so: x - square root of x = 12 or is it x = sqrt(x+10) + 2? if so: x -sqrt(x+10) = 2 Square both sides: Then solve.
It means when y = 0 then x = 1 0 = 1^2 + b(1) + 1 0 = 1 + b + 1 Solve for b.
3n - 4n -4 = 1/3(n+4) -n - 4 = 1/3 (n+4) multiply all parts by 3 -3n -12 = n + 4 -4n = 16 n = -4
4.0 g/1mole = .54 g/x mole This is a proportion. Cross multiply to find the answer
Please help on geometry - analytic geometry
It helps if you plot the points first, then you can find the length of the sides of the triangle. area of a triangle is 1/2 base times height.
That isn't the answer. That was just an example of what consecutive even numbers mean to show why we are using n, n+2 and n+4. My equation is the same as yours.
