Answer:
$ 9.5
Step-by-step explanation:
total money is $20
on lunch = 1/8 × 20 = 5/2 = $2.5
on movies = 2/5 × 20 = $8
total spent = 2.5+8 =$ 10.5
left money = 20-10.5 = $ 9.5

Answer:
The length of diagonal XU is 6.40 units
Step-by-step explanation:
* Lets explain how to find the distance between two points
- The rule of the distance between two points 
  and  is:
 is:
  
* Lets solve the problem
-From the attached figure:
- The coordinates of the vertex X are (2 , 2)
- The coordinates of the vertex U are (-2 , 7)
∴ The point  = (2 , 2)
 = (2 , 2)
∴ The point  = (-2 , 7)
 = (-2 , 7)
∴ 
∴  
∵ 
∴ 
∵ 
∴ d = 6.40
* The length of diagonal XU is 6.40 units
