$\huge\text{Hey there!}$

$\mathsf{20\dfrac{4}{8}+ 19 \dfrac{7}{9} + 15 \dfrac{3}{36}}$

$\mathsf{= \dfrac{20\times8 + 4}{8}+\dfrac{19\times9 + 7}{9}+ \dfrac{15\times36+3}{36}}$

$\mathsf{= \dfrac{160 + 4}{8}+\dfrac{171 + 7}{9}+ \dfrac{540 + 3}{36}}$

$\mathsf{= \dfrac{164}{8}+ \dfrac{178}{9}+ \dfrac{543}{36}}$

$\mathsf{= \dfrac{725}{18} + \dfrac{543}{36}}$

$\mathsf{= \dfrac{1,993}{36}}$

$\mathsf{\approx 55\dfrac{13}{36}}$

$\huge\textsf{Therefore, your answer should be:}$

$\huge\boxed{\frak{55\dfrac{13}{36}}}\huge\checkmark$ $\large\textsf{Or even }\rightarrow$ $\huge\boxed{\frak{\dfrac{1,933}{36}}}\huge\checkmark$ $\large\textsf{(Either should work because they are both EQUIVALENT to each other)}$

The amount of radioactive uranium changes with time. The table below shows the amount of radioactive uranium f(t) left after tim

aniked [119]

Answer:

$f(t) = 100(0.25)^t$

Step-by-step explanation:

The general exponential function is,

$f(t)=ab^t$

The points given in the table are,

$(0,100),(0.5,50),(1,25)$

Putting $(0,100),(1,25)$ in the general equation, we get

$\Rightarrow 100=ab^0$

$\Rightarrow a=100$

And

$\Rightarrow 25=ab^{1}$

$\Rightarrow ab=25$

Putting the value of a,

$\Rightarrow 100b=25$

$\Rightarrow b=0.25$

Now the exponential function becomes,

$f(t) = 100(0.25)^t$
