Abuilding casts a shadow 25 m long. at the same time, the shadow cast by a 44-cm tall pole is 59 cm long. find the height of the building.  a.  17.1 m  b.  32.0 m  c.  33.5 m  d.  18.6 m

For this, we are going to be using proportions to solve. But firstly, we have to convert cm to m. For this, I'll be using dimensional analysis:

Now that we have everything in meters, we can put it into proportions. In this case, our proportion is

Firstly, cross-multiply:

Next, divide both sides by 0.59, and your answer will be x = 18.6 m, or D.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
