Rise over run is another term for slope, with we can use to derive a linear equation.
The term rise over run in technical terms is the change of y over the change of x.
To find the rise over run, subtract the y terms and divide that by the x terms.
You can use this to derive a linear equation as earlier mentioned by plugging in given points.
For example, a line passes through (3,4) with a rise over run of 3.
So therefore the y intercept is -5, and the equation is
Answer:- Equilateral triangle has an order 3 rotational symmetry.
Explanation:-
In geometry, a figure has rotational symmetry if it moves onto itself under rotation about an angle at center of rotation.
The order of rotational symmetry is the number of times the shape moves onto itself throughout a rotation of 360°.
An equilateral triangle has all its sides equal with equal interior angle of 60°.
It moves onto itself three times throughout a rotation of 360°.
⇒Equilateral triangle has an order 3 rotational symmetry.
If you divide 600/ 45 mins you get the kilometers per minute which is 13.33. Then you multiply 13.33 times 30 mins and you get 399.9 or 400 kilometers
