Step-by-step explanation:
Exterior angle theorem
50 + 70 = 120
10/9 can be rewritten as 1 1/9, so it's closest to 1. 2/15 is really small, so close to 0.
The amount of mass after 5 minutes is 75.74 grams.
It is given that
The amount initially = 330grams
After every minute mass decays by 25.5%
<h3>What is the percentage?</h3>
The percentage is the value per hundred.
Amount after 1 min = 330-330*25.5/100 = 245.85grams
Amount after 2 min = 245.85-245.85*25.5/100 = 183.16grams
Amount after 3min = 183.16-183.16*25.5/100 = 136.45grams
Amount after 4 min = 136.45-136.45*25.5/100= 101.66grams
Amount after 5 min =101.66-101.66*25.5/100 = 75.74grams
Therefore, the amount of mass after 5 minutes is 75.74 grams.
