Answer:
See Below.
Step-by-step explanation:
We are given that:
By vertical angles:
Hence, by substitution:
Then by Angle-Angle Similarity:
The formula for x in terms of w is x = 3w² and the formula for y in terms of x is y = (1/112)x³
<h3>Variation</h3>
x = k × w²
w = 4, x = 48
48 = k × 4²
48 = k × 16
48 = 16k
k = 48/16
k = 3
So,
x = k × w²
x = 3 × w²
x = 3w²
y = k/x³
x = 2, y = 14
14 = k / 2³
14 × 2³ = k
14 × 8 = k
112 = k
So,
y = k/x³
y = 112/x³
y = (1/112)x³

Answer:
3m:20m
Step-by-step explanation:
2km to m = 2000
300:2000
(divide both sides by 100)
300/100=3
2000/100=20

If you want you can round it
Answer:
18 eggs for Rs 117
Step-by-step explanation:
Divide 84 by 12 (Dozen = 12) and you get 7 which means every egg is for Rs. 7
Divide 117 by 18 and you get 1.39 which means every egg is for Rs. 1.39
