35. 
5/9= 0.555555556
0.55555556*63=35
2/3= 0.6666666667
0.666666667*63= 42
63-35=28
42-28=14
She has 35 unplanted flowers and must plant 14 more in order to have filled 2/3 of her flower bed. 
        
             
        
        
        
Step-by-step explanation:
1. move the decimal to make the numbers whole 
0.25 - move to the right 2 times - 25
0.044 - move to the right 3 times - 44
2. Multiply 25 * 44 = 1,100
3. Add decimal
you moved the decimal 6 times in total for both numbers...so move the decimal 6 times starting from right.

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form  or
 or 
Find the value of the constant of proportionality k
take any ordered pair from the data 
For x=25, y=160
 
substitute the values of x and y
 
simplify
 
The linear equation is equal to

Answer: 10) 615° & -105°
                12) -440° & 280°
<u>Step-by-step explanation:</u>
Coterminal means it is in the exact same spot on the Unit Circle but one <em>or more </em>rotations clockwise <em>or counterclockwise.</em>
Since one rotation = 360°, add or subtract that from the given angle until you get a positive <em>or negative</em> number.
10) 255° + 360° = 615°     (this is a POSITIVE coterminal angle to 255°)
      255° - 360° = -105°     (this is a Negative coterminal angle to 255°)
12) -800° + 360° = -440°   (this is a Negative coterminal angle to -800°)
     -440° + 360° =  -80°      (this is a Negative coterminal angle to -800°)
       -80° + 360° = 280°     (this is a POSITIVE coterminal angle to -800°)
