Answer:
9
Step-by-step explanation:
shorter leg = x
longer leg = x + 3
Hypotenuse = x + 6
x² + (x + 3)² = (x + 6)²
x² + x² + 6x + 9 = x² + 12x + 36
2x² + 6x + 9 = x² + 12x + 36
x² - 6x - 27 = 0
(x - 9) ( x + 3) = 0
x = 9 or x = -3 (rejected)
Answer: 9.5km
Step-by-step explanation:
The train will take 16 seconds to pass <em>completely</em> through a 300 meter tunnel.
Let suppose that the train moves itself at <em>constant</em> velocity, the vehicles needs to cover the tunnel length () and its length (), both in meters, to pass through the tunnel, the time taken by the train () is described by the following kinematic formula:
(1)
Where is the train velocity, in meters per second.
If we know that , and , then the time taken by the train is:
The train will take 16 seconds to pass <em>completely</em> through a 300 meter tunnel.

Answer:
200
Step-by-step explanation:
Total room =300
Sold room =450
Dally Average Rate =.300
Calculation of revised PAR
=300*300/450
=90,000/450
=200

According to the attached formula:
apothem = side length / 2 * tan (180/number of sides)
apothem = 6 / 2 * tan (180/10)
apothem = 6 / 2 * 0.32492
