In training for the zombie race, Harris runs 4 times back and forth across the pasture, then runs through the woods 3.75 miles. In all, Harris runs 15.7 miles. What is the distance from one side of the pasture to the other?

2.9875 miles

Step-by-step explanation:

15.7 - 3.75 = 11.95. 11.95 / 4 = 2.9875 miles.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
