Allison ran 5 1/4 miles. jimmy ran 3 2/3 miles. how much father did allison run than jimmy
Llana [10]

let's firstly convert the mixed fractions to improper fractions, and then subtract.


\bf \stackrel{mixed}{5\frac{1}{4}}\implies \cfrac{5\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{21}{4}}~\hfill \stackrel{mixed}{3\frac{2}{3}}\implies \cfrac{3\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{11}{3}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{21}{4}-\cfrac{11}{3}\implies \stackrel{\textit{we'll use the LCD of 12}}{\cfrac{(3)21-(4)11}{12}}\implies \cfrac{63-44}{12}\implies \cfrac{19}{12}\implies 1\frac{7}{12}

In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment t
GaryK [48]

Using an exponential function, it is found that the mass of the radioactive sample at the beginning of the 13th day of the experiment was of 169.1 mg.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

At the beginning of the first day of the experiment the mass of the substance was 500 grams and mass was decreasing by 8% per day, hence A(0) = 500, r = 0.08, and the equation is given by:

A(t) = A(0)(1 - r)^t

A(t) = 500(1 - 0.08)^t

A(t) = 500(0.92)^t

At the 13th day, the mass is given by:

A(13) = 500(0.92)^{13} = 169.1
