Answer:
$25.40
Step-by-step explanation:
Find the unit price. So what you do is just divide 304.80 by 12 to get the price of one which comes out to be $25.40
 
        
             
        
        
        
Answer:
The amount of apples is the Xs and The cost is the Ys
Step-by-step explanation:
 
        
             
        
        
        
For this case we have that by definition equals 180 degrees.
 equals 180 degrees.
We must convert 135 degrees to radians, then:

Rounding off we have:
2.4 radians.
Answer:
2.4 radians
 
        
             
        
        
        
<em>Question:</em>
The measures of two complementary angles have a ratio of 3 : 2. What is the measure of the larger angle?
—————
<em>Solution:</em>
Call those two angles  x  and  y, where  x  is the larger one.
If they are complementary, then their sum equals  90°:
x + y = 90°      (i)
Also, the ratio between  x  and  y  is  3 : 2, so
  x           3
——  =  ——
  y           2
Product of the extremes = product of the means:
2x = 3y
2x – 3y = 0        (ii)
Now, just solve this system of equations:
  x  +  y = 90°         (i)
2x – 3y =   0          (ii)
Solve it with elimination. Since you want to know the value of the larger angle, which is  x, then eliminate the variable  y  by doing the following:
Multiply the equation  (i)  by  3,
3x + 3y = 270°        (iii)
2x – 3y =     0          (ii)
 then add both equations, so you cancel out the variable  y:
3x + 2x + 3y – 3y = 270° + 0
3x + 2x = 270°
5x = 270°
         270°
x  =  ———
           5
x = 54°    <———  this is the measure of the larger angle.
I hope this helps. =)
