Answer:
XY 
Represent a distance
√
Represent a segment
√
Represent a numerical value
√
Represent a geometric figure √
Can be found by applying the ruler postulate
√
Can be be duplicated with a compass and a straight edge √
Step-by-step explanation:
The difference between XY and
are that the points XY represents the distance between two points having a numerical value whose value can be found by using a ruler to find difference in the numbers on the ruler that coincides with the points, while
The slope:
m = ( y2 - y1 ) / ( x2 - x1 ) = ( 8 2 ) / ( 3 - 2 ) = 6 / 1
m = 6 ( we have the same slope for AB and A`B` )
AB = √[( 3 - 2 )² + ( 8 - 2 )²] = √37
A`B` = 3.5 √37 = 21.29
Answer:
His wife gets $336 more than his son.
Step-by-step explanation:
Colin and Brian:
Ratio of 4:1.
So Colin gets
of the prize.

Colin got $1680. Dividing between himself, his wife and their son:
Ratio of 2:5:3.
So Colin gets
, his wife gets
and his son gets 
Wife:

His wife got $840.
Son:

His son got $504.
How much more does his wife get over their son?
840 - 504 = 336
His wife gets $336 more than his son.
