Answer:

4 cm (A)

Step-by-step explanation:

triangle BAC is just a larger version of triangle EAD. given that ED is 5cm, and BC is 10cm, triangle BAC must be twice the size of EAD. since the ratio of AD to ED is 4:5, and BC is twice the size, all we need to do is multiply both sides by 2 to find length AC. 4*2 = 8. now we can subtract length AD from AC to get CD. 8 - 4 = 4.

Tea is made up of milk and tea ratio of 2 to 9. how much tea can be made using 1 litre of milk

Ilya [14]

You can solve it like this

2=milk (a); 1=milk (b)
9=tea (a); x= tea (b)

2:9=1:x (then multiply means and the extremes)
(means are 9 and 1; extremes are 2 and x)

9=2x
9/2= x
4.5 or 4 1/2=x

Therefore, using 1 litre of milk, we can have 4 1/2 tea.
