Earth orbits the sun in an elliptical pattern. The equation of Earth's path is.... where the measurements represent millions of
Triss [41]

General equation of Ellipse centered at (h,k) is given as

\frac{(x-h)^{2}}{a^{2}} + \frac{(y-k)^{2}}{b^{2}} =1\\

where a is the radius along x-axis

and b is radius along y-axis.

Given : The equation of elliptical path of Earth as

\frac{(x+2.5)^{2}}{22350.25} + \frac{y^{2}}{22344} = 1\\

Comparing the equation with the general equation, we get

(h,k) as (-2.5,0)

a = \sqrt{22350.25} = 149.5

b = \sqrt{22344} = 149.48

We have the Sun located at the coordinate (0,0).

Hence, the distance between Sun and Earth in July = 149.5 + 2.5 =152

∴ Earth's distance from the Sun in July is 152 million kilometers.

861 ÷3 show work for this problem please
TEA [102]
861 divided by 3: 

How many times does 3 go into 8? 2 x 3 = 6 
Subtract 6 from 8 to get a remainder of 2, and bring down 6 to get 26. 

How many times does 3 go into 26? 8 x 3 = 24
Subtract 24 from 26 to get a remainder of 2, and bring down 1 to get 21. 

How many times does 3 go into 21? EXACTLY 7 times. 7 x 3 = 21

Collect all numbers in bold to get…. 287!

Therefore, 861 divided by 3 = 287.
