Answer:
The mass of the radioactive sample after 40 minutes is 12.8 g.
Step-by-step explanation:
The mass of the sample can be found by using the exponential decay equation:
Where:
N(t): is the amount of the sample at time t =?
N₀: is the initial quantity of the sample = 120 g
t = 40 min
λ: is the decay constant = 0.056 min⁻¹
Hence, the mass of the sample after 40 min is:
Therefore, the mass of the radioactive sample after 40 minutes is 12.8 g.

I just did this at school lol
1. Fiscal differences
Democrats are usually pro-regulation, and Republicans are for a free market. However, both are pro-capitalism. Examples: 15 dollar minimum wage, Green New Deal
2. Social differences
Democrats tend to be more progressive in social view, meanwhile Republicans tend to want to stick to the traditions. This means LGBT, abortion BLM, etc.
3. Climate change
Most Democrats recognize that climate change is a problem (they wont do anything about it, but at least they recognize it I guess.) Most Republicans think that climate change is normal and there is nothing to do about it.
To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.
