<span>if we take the centre of the circle as being the origin, we can say that
x coordinate is :cos o = x/r so x
= r cos o
</span><span>
and
y coordinate : cos(90-teta)= y/r
so y=r*cos(90-teta)
</span><span>
if teta is 29 degrees
y=r*cos(61)
and
x = r * cos(29)</span>

Determine fraction of each teacher
Each fraction is calculated by dividing total fraction by number of teachers as follows:




I'm horrible at this so I'm just guessing.
X is the variable and x means multiplication symbol.
X + (X x 3 - 1) + (X x 3 - 1) - 4) <span>≥ 45 is the answer I got.
The answer to that inequality would be
X </span><span>≥ 7 I think.</span>
The answer is E. If you draw the quadrilateral out, you can clearly see what it looks like. And you can know from the coordinates that the diagonal of this quadrilateral is not equal. So it can not be rectangle. And also AB//CD and AD//BC.
Answer:
Step-by-step explanation:
Change the 2/3 to 4/6
Now the ratio becomes 3:4:6
So the number of each is
3x + 4x + 6x = 520
13x = 520
x = 40
Red = 3*40 = 120
Yellow = 4*40 = 160
Blue = 6 * 40 = 240
Total = 520
