Answer:
D
Step-by-step explanation:
The formula we need to solve this is:
Where
is the distance from one focus to the vertex
is the second distance from another focus to same vertex
<u>Note:</u> Here, vertex point is the point on top. The common point from which the RED and BLUE line meets the 2 foci
is half the length of the major axis (which is 9 here since total major axis is given as 18)
<em>Now we can plug into the equation and solve:</em>

<em>D is the correct answer.</em>
You purchase 4 videos
The original price of each video is x dollars
You decide to purchase the limited edition versions of the videos for an additional cost
Your total cost is (4x + 20) dollars
So, total additional cost is $20
since, we are purchasing 4 videos
so, additional cost in each videos is
So, limited edition cost additional $5 per videos.........Answer
Answer:
is the fraction of people wearing with black shoes.
Step-by-step explanation:
Given:
If there's 15 players total, 1/3 are wearing red shoes, 2/5 are wearing blue shoes and everyone else is wearing black shoes.
Now, to find the fraction of people with black shoes.
Total players = 15.
Fraction of people wearing red shoes =
So, number of people are wearing red shoes:
Fraction of people wearing blue shoes =
Thus, number of people wearing blue shoes:
And rest are wearing black shoes.
Now, to get the number of people wearing black shoes by subtracting number of people are wearing red shoes and blue shoes from the total number of players:
Thus, the fraction of people wearing black shoes:
=
Therefore, is the fraction of people wearing with black shoes.
