ANSWER
D. 14
EXPLANATION
The ratio of the books in the book case are:
Red:Yellow:Green=3:5:2
The number of yellow books in the book case is 35.
If 5 corresponds to 35, then 2 green books will correspond to a less number of books,
By proportion, because it is going to be less more will divide.
The number of green books in the book case is
Answer:
First row: 5(1)-4; 1; (1,1)
Second row: 5(2)-4; 6; (2,6)
Third row: 5(3)-4; 11; (3,11)
Step-by-step explanation:
Plug in the value of x to get the value for u then write the coordinates. So first value of x is 1 so put a 1 where the x is in this equation 5x -4. 5(1) - 4 =1 so the value of y is 1. So when x is 1 y is equal to 1 (1,1). Do the same for 2 and 3.
Let x = download size of the standard version.
4515 - x = download size of high quality version.
High quality was downloaded 4 times more so 4 x 4.8 = 19.2 = downloads of high quality versions.
Set up a ratio:
2.3 / 19.2 = x / 4515-x
Cross multiply:
2.3(4515-x) = 19.2x
10384.50 -2.3x = 19.2x
Add 2.3x to both sides:
10384.50 = 21.5x
Divide both sides by 21.5:
X = 10384.50/21.5
X = 483
There were 483 downloads of the standard version.

Step-by-step explanation:
Given: In ΔGHI, =90°, IG = 6.8 feet, and HI = 2.6 feet
To find:
Solution:
Trigonometry defines relationship between the sides and angles of the triangle.
For any angle ,
= side opposite to /side adjacent to
In ΔGHI,
Put
So,
Therefore,
