The answer is:  " 40 students " .
______________________________________________________
Explanation:
______________________________________________________

60% of x = 24 .  Find "x" .  in which "x" = total number of students; 

60 % = 60/100 = 6/10 = 3/5.

(3/5) x = 24 ;

Multiply EACH SIDE of the equation by "5" ; to get rid of the fraction:

5* (3/5)x = 24*5 ; 

3x = 120 ;

Divide each side of the equation by "3" ; 
   to isolate "x" on one side of the equation; and to solve for "x" ; 

3x / 3 = 120 / 3 ; 

 x = 40 .
______________________________________________________
The answer is:  " 40 students " .

If the angle bisectors of a pair of opposite angles of a quadrilateral are the opposite sides of a parallelogram formed by the t
Novosadov [1.4K]

Answer:

The correct answer is;

No, the quadrilateral is not always a parallelogram

Step-by-step explanation:

Since there are only four opposite angles in a quadrilateral there are only two possible angle bisectors of the opposite angles also, the angle bisectors of a pair of opposite angles of a quadrilateral will intersect within the quadrilateral and therefore they cannot form the sides of a parallelogram

Therefore, the answer is no, the quadrilateral is not always a parallelogram.

Answer:

Coordinates of point P is (-14,3).

Step-by-step explanation:

Given that mid point of line segment \overline {PQ} is at <em>M(-9, 8.5).</em>

Q is at <em>(-4, 14)</em>.

Let coordinate of P be (x,y).

Using the ratio, we can say the following:

<em>The coordinates of mid point</em> (X,Y) of a line with endpoints (x_1, y_1) and (x_2, y_2) is given as:

X=\dfrac{(x_1+ x_2)}{2}

Y=\dfrac{(y_1+ y_2)}{2}

Using the formula for above given dimensions:

-9 =\dfrac{x+(-4)}{2}\\\Rightarrow x = -18+4 = -14

8.5=\dfrac{(14+ y)}{2}\\\Rightarrow y = 17-14 =3

So, the <em>coordinates of point P are</em> (-14,3).
