Since the circumference meaning the whole line is 22 centimeters long then the radius would be half of that...sooo....22/2=11. The radius for N is 11cm...hope it helps :)
If you are mixing a 30% solution with a 20% solution to obtain a 14% solution, you will never obtain a 14% solution.
You are solving quadratic equations. to do so, use the quadratic formula when possible, or factor. 15- for example, you can factor (x+5)(x+3), therefore x=-5,-3. You then go back and plug in your answers to see if you can eliminate any of them.
6.89(1.21) = 8.3369 rounds to 8.34 <==
or u could also do it this way...
6.89 + 0.21(6.89) = 6.89 + 1.4469 = 8.3369 rounds to 8.34 <==
