Answer:
Step-by-step explanation:
Given as :
The distance cover while running = 
= 5 miles
Let The speed for running = 
The distance cover with bike = 
= 80 miles
The speed for biking = 
= 15 mph +
Total Time taken = 5 hours
Now Time = 
∴ 5 hour = 
+ 
Or, 5 hour = 
+ 
Or, 5 hour = 
or, 5 × (
) = 
Or, 
- 
= 0
or, 
= 0
or, 
= 0
Or, 
= 0
Or, 
= 0
Or, 
= 0
∴ = 3 , - 5
So, the running speed = 3 mile per hour
And the biking speed = 15 mph + 3 mph = 18 mile per hour
Hence The running speed of Stu is 3 mile per hour . Answer
You click on the button that says "Y=" then you type in the equations into y=1 , y=2 and so forth. click graph and the lines will appear. use the up, down, left, and right buttons to move the cursor and find the exact point.
A picture can help.
The median to the long side divides the isosceles triangle into two right triangles with hypotenuse 10 and short leg 6. Thus the long leg (median of interest) is found by the Pythagorean theorem to be
... √(10² -6²) = √64 = 8
Then the midpoint of the short side is found to be 6 + (6/2) = 9 units to the side and 8/2 = 4 units above the opposite vertex. Hence the square of the length of that median is 9² + 4² = 97.
The sum of squares of interest is
... 8² + 2×97 = 258
The equation you'd make would be (2x-2)+(2x-2)+x+x=20 because the length is 2 m less than the width (x). To simplify, it'd be 6x-4=20 because you combine like terms. You then move the -4 over to the 20 to make it 6x=24. The final answer is 4 meters.
