B. Fractions have to have the same denominator so $\frac{9}{10} - \frac{2}{5} = \frac{9}{10} - \frac{4}{10}$ which = $\frac{5}{10}$ then you simplfy it to $\frac{1}{2}$ so it would be B

Answer:

$r = 1036.725\,mi$

Step-by-step explanation:

The distance per unit grade on Earth is:

$\Delta s = \frac{2\pi\cdot (3960\,mi)}{360}$

$\Delta s \approx 69.115\,miles$

The distance between Pittsburgh and Miami is:

$r = (69.115\,mi)\cdot (40.5^{\textdegree}-25.5^{\textdegree})$

$r = 1036.725\,mi$

4000000000000000000000^50 is the same thing. Ain't no mathematician wants to simplify that. Mathematicians are lazy. So you would leave it the way it is.
