30......................127,5
1.........................x
30x = 127,5
x = 127,5/30
x = 4,25
1 libra = 4,25 pizzas
4,25 pizzas.............1 libra
1 pizza.....................y
4,25y = 1
y = 1/4,25
y = 0,2353 libra (1 pizza)
1/8 de pizza = 0,2353/8 = 0,0294
Answer
Find out the length of the pole .
To proof
As given
The pole casts a 12-foot shadow when the sun is at a 40° angle of elevation.
x represented the length of pole .
As shown in the diagram
By using the trignometric identity


tan40° = 0.839099631 ( approx )
Put in the above
x = 12 × 0.839099631
x = 10.1 foot (approx)
Therefore the length of the pole in 10.1 foot (approx) .
