Can I know if part c is correct? ​

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?

Is it true or false i’m trying to pass this test so i can leave school

M. xyz =radians. covert this radian measure to its equivalent measure in degrees.
