b).what percent of the business was owned by kristen round to the nearest 10th.
c). if the business grows 3,000,000 what percent of it will julie own. round to the nearest 10th

A) $15,000 and $36,000  

B)  70.59%

C) 29.41%

Step-by-step explanation:

A) Given that they invested in the ratio 5:12 then 5/(5+12) = 5/17 was invested by Juli and 12/17 was invested by Kristen. In money that is:

Juli: 5/17 * $51,000 = $15,000

Kristen: 12/17 * $51,000 = $36,000  

B) The percent owned by Kristen is 12/17*100 = 70.59%

C) The percent owned by Juli is 5/17*100 = 29.41%

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
