Answer:
He will finish the biking at 6:30 pm 
Step-by-step explanation:
1/4 hour is same as 1/4 * 60 = 15 minutes 
1 2/5 miles is same as 1.4 miles 
He bikes 1.4 miles in 15 minutes 
then he will bike 14 miles in 15 * 10 = 150 minutes 
150
minutes is same as 2 hours 30 minutes 
Adding this to 4 pm, we will get;
6:30 pm 
 
        
             
        
        
        
See the picture attached with letters to better understand the problem
in the right triangle ABD
applying the Pythagoras theorem
8²=AD²+(x+4)²-----> AD²=64-(x+4)²------> equation 1
in the right triangle ADC
applying the Pythagoras theorem
12²=AD²+(2x+1)²-----> AD²=144-(2x+1)²------> equation 2
equate equation 1 and equation 2
64-(x+4)²=144-(2x+1)²-------> 64-[x²+8x+16]=144-[4x²+4x+1]
64-x²-8x-16=144-4x²-4x-1
4x²-x²-8x+4x=144-1-64+16
3x²-4x=95
3x²-4x-95=0
using a graph tool----> to resolve the second order equation
see the attached figure N 2
the solution is
x=6.33
the answer isx=6.33 units

You’re Right
Orientation of a Shape is the arrangement of its points after a transformation. Translations don’t change the positions of the points relative to the shape.
A reflection would be a example of a change in orientation, since the point places will change.
I hope you understood :)
        
             
        
        
        
Use photomath it works better with functions rather than brainly
