it's wrong
correct answer is 7.5 inches
r=d/2
=15/2
=7.5
Total mass of salt in the 2100 grams of solution = 15 + 0.05 * 210 = 25.5 grams
as a percent this is (25.5 * 100) / 210 = 12.14% Answer
I believe the answer is -x
I hope this helps!
(-3,4) (-1,4) (-3,7) are the co ordinates
You have to add more there is no context here, apologies but try to make another question with maybe a picture and more text?
