<span>The center, vertex, and focus all lie on the line y = 0. Then we know that the equation of a hyperbola is a^2 + b^2 = c^2 . a^2 represents the x part of the equation and the y part will be subtracted. We know that the vertex is 48 units from the center and that the focus is 50 units from the center. Then we have that b^2 = 2500 - 2304 = 196 .
Thus the equation that represents the hyperbola is x^2/2304 - y^2/196 = 1 or 49x^2 -576y^2 - 112896 = 0</span>
In the case : <span>If mA=mB and mA + mC=D, then mB+mC=D the </span>Transitive Property is shown.The transitive property states that if A=B and B=C, then A=C. In our case, A is mB, B is mB .

Step-by-step explanation:
Answer: 80 men
Step-by-step explanation:
Let m represent the number of men , w , the number of women and c the number of children , then we have:
m : w = 4 : 5 ............... equation 1
w : c = 10 : 9 ............ equation 2
Multiply equation 1 by 2 so as to get the ratio m:w:c , that is
equation 1 becomes : m: w = 8 : 10
so the combine ration m : w : c is 8 : 10 : 9
The total ratio is therefore 8 + 10 + 9 = 27
number of men = ratio of men/ total ratio X 270
number of men = 8/27 X 270
number of men = 8 X 10
number of men = 80
