Answer:
0.40 feet
Step-by-step explanation:
For the first scenario, a 50-foot building casts a shadow of 1 foot. Let the angle of elevation of the sun from the shadow be denoted as θ.
Then:
Tan θ =
Tan θ =
Tan θ = 50
⇒ θ = 50
= 88.8542
=
The elevation angle is roughly .
For a 20-foot pole,
Tan θ =
Tan =
x =
= 0.4015
= 0.40 feet
The length of the pole's shadow is 0.40 feet.
The recipe uses 
cups of white flower together with 6 cups of wheat flower.
Therefore, the combined quantity of flower equals
If
represents that combined amount, the equation to write is:
Constraints are as follows:
y can only be
6
Note that if y = 0 then x would have to be -6, which is not possible.
Therefore, the combined quantity of flower equals
