30 grams
Step-by-step explanation:
half life is 60 days so every 60 days the amount 480 grams will be half
in 240 days will decay 240 /60 = 4 times
once 480 /2 = 240

four times 60/2 = 30 grams will be left
Answer:
39 units by 51 units
Step-by-step explanation:
The painting is a scale factor of 1/3, so each side length is 1/3 of the original. To find the original multiply both side lengths by 3.
13x3 = 39
17 x 3 = 51
We add 0.00055+0.00104 together.
0.00104+0.00055= 0.00159
