$\bf \begin{array}{ccll}
miles&hours\\
\cline{1-2}
50&1\\
120&h
\end{array}\implies \cfrac{50}{120}=\cfrac{1}{h}\implies h=\cfrac{120\cdot 1}{50}\implies \stackrel{\textit{2 hours and 24 minutes}}{h=2.4}$

The planets move around the sun in elliptical orbits with the sun at one focus. The point in the orbit at which the planet is cl

gladu [14]

Consider the attached ellipse. Let the sun be at the right focus. Then perihelion is at right vertex on the x-axis and aphelion is at the left vertex on the x-axis.

The distances:

from perihelion to the sun in terms of ellipse is a-c;
from aphelion to the sun in terms of ellipse is a+c.

Then

$\left\{\begin{array}{l}a-c=741,000,000\\a+c=817,000,000\end{array}\right.$

Add these two equations:

$2a=1,558,000,000 \\ \\a=779,000,000$

and subtract first equation from the second:

$2c=76,000,000 \\ \\c=38,000,000.$

Note that $b=\sqrt{a^2-c^2},$ thus

$b=\sqrt{779,000,000^2-38,000,000^2}=\sqrt{605,397,000,000,000,000}.$

The equation for the planet's orbit is

$\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1\Rightarrow \dfrac{x^2}{606,841,000,000,000,000}+\dfrac{y^2}{605,397,000,000,000,000}=1.$

Step-by-step explanation:

Here, we want to know which of the options would be true if we replace the term in the box ( D) by the value 1,537.

The correct option here is thus D

What we have here would be

1537 > 1,357

This can be read as 1537 is greater than 1,357 which is correct
