Setting up a proportional relationship between mirror and lamppost, the height of the lamppost is 10 feets.
Setting up a proportional relationship :
Cross multiply :
Hl × 3 = 6 × 5
3Hl = 30
Hl = (30 ÷ 3)
Hl = 10

Answer: 10 feet
Step-by-step explanation:
Let h be the height of lamppost.
Since both the person and the lamppost are standing vertical to the ground, making similar right triangles.
Because the two triangles are similar, the ratio of their sides is the same.
Therefore, we have
Hence, the height of the lamppost = 10 feet.
Answer:
The recipe calls for 4/3 cups of oatmeal and 9/2 cups of flour.
If we convert them to a common denominator, we have 8/6 cups of oatmeal and 27/6 cups of flour, so, the ratio is 8:27.
If you use 6 cups of oatmeal and 9 cups of flour, the ratio will become 2:3 and will no longer be proportional
