The shorter piece is 37 cm
The longer piece is 48 cm:
Step-by-step explanation:
Divide 85 cm by 2 = 42.5
Divide 11 cm by 2 = 5.5
Add them together = 48 cm
85 cm - 48 cm = 37 cm

Answer:
The most cost-effective company is Painting USA .
Step-by-step explanation:
Given as :
The charges applied by the Painting USA = $ 75 + $ 25 per hour labor charge
The charges applied by the Upscale Home Painting = $ 40 per hour
The total time required to paint the Paul's house = 25 hours
Now, Let the  charges applied by the Painting USA = $ x
And  charges applied by the Upscale Home Painting = $ y
So, x = $ 75 + $ 25 × 25 hour
Or, x =  $ 75 + $ 625
∴   x = $ 700
So, The charges applied by the Painting USA =  x = $ 700 
And y = $ 40 × 25 hour
∴     y = $ 1,000
So , The charges applied by the Upscale Home Painting =  y = $ 1,000
As $ 700  $ 1000
 $ 1000
So, x  y
 y
Hence The most cost-effective company is Painting USA . Answer
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Let the distance the slower hiker travels=d,
the distance the faster hiker travels=15-d (Since, the sum of the distances they walk is 15mi).
Let the speed of the slower hiker in mi/hr=s,
the speed of the faster hiker=s+0.5
Now, equation for the slow hiker:

 (1)
                                                            (1)
and equation for the faster hiker:


 (2)
                                                       (2)
Now, substituting the equation (1) in equation (2),



and 
The speed of the slower hiker is  and The speed of the faster hiker is
and The speed of the faster hiker is  .
