Answer:
10 : 17
Step-by-step explanation:
Male runners = 35
Female runners = 50
Total runners = male runners + female runners
= 35 + 50
= 85 runners
What is the ratio of the number of female runners to the total number of runners?
Ratio of the number of female runners to the total number of runners = number of female runners : total runners
= 50 : 85
= 50 / 85
= 10/17
= 10 : 17
Ratio of the number of female runners to the total number of runners = 10 : 17
The angle measures must sum to 360 in order for the figure to tessellate about a vertex.
The side length ratios of an isosceles right triangle are 1-1-
. So,
the length of a leg would be equal to the length of the hypotenuse divided by the square root of 2.
Using pythagorean theorem (c is the hypotenuse, a and b are the legs)
c²=a²+b²If the triangle is isosceles, two side lengths must be equal. In the case of a right triangle, the legs must be equal in length. So, b=a.
c²=a²+a²c²=2a²a²=c²/2a=c/a≈c/1.414
