Answer:
The number of Girls players in the Team of 18 players is 6 .
Step-by-step explanation:
Given as :
The total number of player including boys and girls = 18
And 
times girls player + 
times boys player = 7
Let The number of boys player = B
The number of girls player = G
So, According to question
G + B = 18 ...1
× G + × B= 7
or, 
+ 
= 7 ...2
or, Put the value of B from eq 1
or, + 
= 7
Or, - 
+ 6 = 7
or, 
= 7 - 6
Or, 
= 1
∴ G = 1 × 6 = 6
Hence The number of Girls players in the Team of 18 players is 6 . Answer

Answer:
4 m
Step-by-step explanation:
The geometry is that of a right triangle with hypotenuse 8.5 m and one side of length 7.5 m. If "b" represents the distance from the base of the ladder to the wall, the Pythagorean theorem tells us ...
b² + 7.5² = 8.5²
b² + 56.25 = 72.25
b² = 16 . . . . . . . . . . . . . subtract 56.25
b = 4 . . . . meters . . . (take the square root)
The base of the ladder is 4 m from the wall.
