We can solve this problem by setting up a proportion. When creating the proportion it is important to keep the units aligned. Our proportion would look like this:
We are looking for x, the amount of sugar she needs with 40% sugar syrup. To solve, we can cross multiply and divide. We cross multiply 10 x 40, then divide by 25:
10 x 40 = 400
400/25 = 16
Ms. Maryna needs 16 lbs of sugar to make 40% sugar syrup.

Pythagoran theorem
length of ladder=hyptonuse
height of window is one leg
distance base is fram building is other leg
a²+b²=c²
c=hyp
a and b are legs
18²+b²=20²
324+b²=400
b²=76
b=2√19ft or aprox8.7178ft
