Using the cosine theorem we have the following equation:
d ^ 2 = (800) ^ 2 + (840) ^ 2 - 2 * (800) * (840) * (cos (150-45))
We cleared d:
d = root ((800) ^ 2 + (840) ^ 2 - 2 * (800) * (840) * (cos (150-45)))
d = 1301.327321
Nearest whole number:
d = 1301 miles
Answer:
The airplanes are far about:
d = 1301 miles

Answer:
![x = y - 7](https://tex.z-dn.net/?f=x%20%3D%20y%20-%207)
Step-by-step explanation:
1. Create an equation
<em><u>Concept</u></em> :
If x = 5, then subtracting 5 from both sides gives you x - 5 = 0. Do this to both variables
If x - 5 = 0 and y - 12 = 0, those two statements equal the same thing. So
![x - 5 = y - 12](https://tex.z-dn.net/?f=x%20-%205%20%3D%20y%20-%2012)
2. Add 5 to both sides to isolate variable X
![x = y - 7](https://tex.z-dn.net/?f=x%20%3D%20y%20%20-%20%207)
3. (Optional) Plug given values into new equation to check answers
![(5) = (12) - 7](https://tex.z-dn.net/?f=%285%29%20%3D%20%2812%29%20-%207)
5 = 5 is a true statement
Answer:
20 homes
Step-by-step explanation:
Given that :
Total number of homes = 800
Average years at which homes are listed = 8 years
To obtain the annual home listing = total number of Homes / average years
Annual home listing = 800 / 8
Annual home listing = 100 homes
If 20% of the homes are listed on the year in question :
20% of 100 homes
0.2 * 100
= 20 homes
20 homes can be listed that year
