Answer:

a) Similar triangles are triangles with the same shape but not necessarily the same size

b) 15/45 = 8/x

1/3 = 8/x (simplify the 15/45)

x = 8 * 3 (cross multiplication)

x = 24

c) y^2 = 15^2 + 8^2 (Pythagoras theorem)

y = *square root of* 15^2 + 8^2

y = 17

1/3 = 17/z

z = 17 * 3 (cross multiplication)

z = 51

How do I solve this math question? give full explanation using a formula. ​
lukranit [14]

Answer:

30 short cakes

Step-by-step explanation:

25ml = 10ml + 10ml +5ml

each 10ml of milk can make us 12 short cakes

we can two 10ml of milk (20ml) which can make us 24 short cakes.

but we have 25 ml of milk so how much does 5ml of milk give us if 10ml of milk gives us 12 short cakes ?

5ml makes us 6 short cakes. 24 short cakes plus 6 short cakes =30 shortcakes.

25ml of milk =10ml(12shortcakes)+ 10ml(12 shortcakes)+5ml(6 shortcakes)
