The formula for the length of the hypotenuse in a right triangle is Va? + b2 where a and b are the lengths of the triangle's sides (this formula is derived from the Pythagorean theorem).
From the side, a certain ramp has a right-triangular shape. Its height is 30 centimeters and its horizontal
length is 3 meters.
What calculation will give us the estimated length of the ramp in meters?

Greek city-states developed instead of a single state: The geography did a key role in setting apart the Greek cities, imposing natural barriers as the ocean, mountains and vast distances separated and prevented a unified state. Each city had also its characteristic culture and self-governed, this created a Mediterranean landscape where Greek culture flourished Important cities like Athens, Crete and Sparta developed their unique features: The Spartans to the West became fierce warriors and specialized in combat and armor building. Athens became a center of culture, science and religious practices, the greatest temples can be found there. Contact from other cities was possible yet the independence and autonomous rule were preferred. The city-states had been naturally isolated and divided by geographical barriers, yet sea allowed as well Greeks to become experts on the sea see the image below for further reference

Step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
