One banana is an eight of 96 cents. 96/8 is equal to 12 cents.
Answer: weeks
Step-by-step explanation:
Given
It takes 14 weeks to empty a lake
also it takes 20 weeks for a river to fill the lake
Part of lake empty in 1 week
Part of lake filled in 1 week is
And if both works simultaneously then
therefore it takes weeks to fill it
Answer: BC is 9 units long
==============================================================
Work Shown:
Let x be the length of segment BC.
BC is parallel to DE, so this means that triangle ABC is similar to triangle ADE.
Side AB pairs with side AD (both are horizontal sides of triangle ABC and triangle ADE respectively)
Side BC pairs with side DE (both are vertical sides of triangle ABC and triangle ADE respectively)
Because of those facts above, we can end up with this proportion
AB/AD = BC/DE
-------------------
Let's plug in the given values and isolate x
AB/AD = BC/DE
12/20 = x/15
12*15 = 20*x ... cross multiply
180 = 20x
20x = 180
20x/20 = 180/20 ... divide both sides by 20
x = 9
Segment BC is 9 units long.
note: There is no need to calculate the length of segment AE. Though you are correct in stating that AE = 25.
