A company makes picture frames for different sized pictures. A customer has several rectangular-shaped photographs that he wants

to be framed. All of the photographs measure 10½ inches for width but vary in length.
The manager at the frame shop knows she can use the formula for perimeter, P = 2l + 2w, to determine the amount of wood that she’ll need for each photograph.



One of the photos is 20¾ inches long. How much wood is needed for the frame? The type you answer as a decimal, not a fraction.

A radioactive substance has a continuous decay rate of 0.056 per minute. How many grams of a 120 gram sample will remain radioac
sammy [17]

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:

N_{t} = N_{0}e^{-\lambda t}

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:

N_{t} = N_{0}e^{-\lambda t} = 120g*e^{-0.056min^{-1}*40 min} = 12.8 g

     

Therefore, the mass of the radioactive sample after 40 minutes is 12.8 g.

I hope it helps you!
