I’m not so sure, whether I understood the question. But I think you will read it seven hundreds seventy times 6 equals to seventy seven times six times hundred. In addition, the answer is 4,620 and it can be read four thousand six hundred twenty.
Not sure what the mess above me says, but basically as long as you have an equation for the circle, you can plug the coordinates of your point into the x and y values of the equation and see if it equals out. If you don’t have an equation, you can just make one. Use (f-k)^2+(x-h)^2=r^2 where h and k are the coordinates of the center of the circle and r is the radius. Hope this helps!
divide 63 by9
63 / 9 = 7
each piece is 7 meters long
Each half-life reduces a sample by one half.
So after 1 half-life there is 1/2 left
2 half-lives 1/4
3 half-lives 1/8
4 half-lives 1/16
5 half-lives 1/32
There would be (1/32) of 120 remaining.
or 3.75 grams.
