Exchange rate L 1 = $ 1.5542
Mary has $ 135
Pounds that Mary exchanged 135/1.5542
= L 86.8614 = L 87
DC/AC=EC/BC
x/(x+3)=10/16
10(x+3)=16x
10x+30=16x
30=6x
x=5
DC=x=5
DC=5 units long
10/16=DE/AB, DE=y
10/16=y/10
16*y=10*10
y=6.25≈6.3
DE≈6.3
900 : 1
The linear ratio = a : 30a = 1 : 30
volume ratio = 1³ : 30³ = 1 : 900
ratio of larger to smaller = 900 : 1
