For questions no. 4 and 5. Given: Radium decomposed at a rate proportional to the quality of radium present. Suppose that it is found that in 25 years approximately 1.10% of a certain quantity of radium has decomposed. Determine approximately how long it will take for ½ the original amount of radium to decompose. 4. The value of the constant of proportionality is 5. The amount of unconverted substance at any time t is given by
