In beta- decay, a neutron becomes a proton, leaving an atom of 24Mg
(magnesium, which has 12 protons compared to 11 for sodium)
parent element
24 11 Na
(apex)
24 12 mg
The equation for the negative beta decay of 24Na is: 1124Na --> 1224Mg + -10e Where e represents the beta particle, which can also be viewed as an electron.
When radium-226 undergoes alpha decay, it becomes radon-222. We write the equation like this: 88226Ra => 24He + 86222Rn Here we see the alpha particle written as a helium-4 nucleus, which is, in point of fact, what it is. Notice that the numbers that are subscripted are equal on both sides of the equation, and the superscripted numbers are as well. They must balance for your equation to be correct.
The equation for half-life decay is AT = A0 2 (-T/H) so, plug in 28, 24, and 84 and you get AT = (24) 2 (-84/28) AT = (24) (0.125) AT = 3 Of course, that's the formal way to do it. In this case, one could also have divided 84 by 28, giving 3, which means that 3 half-lives would be used, and that is simply 1/23 or 1/8.
Apply to the equation V=U+at . The answer is 40.

The equation for the beta decay of 24Na is: 1124Na --> 1224Mg + -10e where the e is a negative beta particle or electron.
x-11=13, x-11+11 = 13+11, x=24 No, 28 is not the solution to the equation
Any of the following... 24=n*0.75 0.75*n=24 (75*n)/100=24
5 - 7b + 6 = -24 is a linear equation in one variable. 11 - 7b = -24 Adding -11 to both sides 11 - 7b + (-11) = -24 + (-11) 11 - 7b - 11 = -24 - 11 -7b = -35 Dividing both sides by -7 -7b/(-7) = -35/(-7) b = 5
undefined.
11+11+1+1= 24
9, 11, 13, 15 The solution equation is A + B = 24 where B = A +2 (the consecutive odd integer) 2A +2 = 24 A = 11, B = 13
Without an equality sign and not knowing the plus or minus values of 3y and 24 it can't be considered to be a straight line equation. But if you mean: 4x+3y = 24 then the coordinates of the line are (6, 0) and (0, 8)
2a/3=8+4a2a=3(8+4a) 2a=24+12a -10a=24 a=-24/10 a=-12/5
