$x=1.212121... \\
100x=121.2121... \\
100x-x=121.2121...-1.212121... \\
99x=120 \\
x=\frac{120}{99} \\ x=\frac{40 \times 3}{33 \times 3} \\ x=\frac{40}{33}$

The fraction is 40/33.

Speed = 100 km/h

hike in speed = 25 %

Let the true speed is v.

$v + 15% of v = 100 \\\\v + 0.15 v = 100 \\\\1.5 v = 100\\\\ v = 87 km/h$

What is the length of the hypotenuse of the triangle when x=14

astra-53 [7]

The length of the hypotenuse will be equal to H=122.25 when value of x=14.

<h3>What is pythagorean theorem?</h3>

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal the square of the sum of the other two sides.

It is given that:

Value of x=14

The perpendicular is =6x+5=6x14+5=89

The base is =6x=84

So by using the Pythagorean theorem:-

$H^2=P^2+B^2\\\\\\H^2=89^2+84^2\\\\\\H=\sqrt{89^2+84^2}\\\\\$

Hence the value of hypotenuse will be H=122.25
