a pole that is 3.3 M tall casts a shadow that is 1.22 M long at the same time a nearby Tower cast a shadow that is 50.75 M long
jenyasd209 [6]
Since there is no distance between the pole and the base of the tower, we can assume that the pole is at the base of the tower. 
We can create a right triangles between the pole and its shadow and between the tower and its shadow as shown in the figure. Let x be the height of the tower. Since our triangles are similar the ratio between its sides is going to be proportional, so we can establish a proportion to find x:
\frac{x}{3.3} = \frac{50.75}{1.22}
x= \frac{(50.75)(3.3)}{1.22}
x=137.27

We can conclude that the tower is 137.27 meters tall.

Un fabricante de ventanas cuadradas cobra a razón de 3 euros por cada metro de marco y 12 euros por el cristal, sean cuales sean
lesya [120]

Answer:

Givens

  • The cost of the square windows is 3 euros per meter, and 12 euros for the crystal.

<h3>If a window has 2 meters side, how much would it cost? (A)</h3>

Notice that the window is a square, that means all four sides are congruent, so it has 8 meters in total, which would cost 24 euros plus the crystal. Therefore, the total cost of a window with 2 meters side is 24+12 = 36 euros.

Specifically, the function of the cost is: C(x)=3x+12, where x represents meters of sides. (C)

<h3>If we paid 60 euros, the dimensions are (B)</h3>

60=3x+12\\60-12=3x\\x=\frac{48}{3}=16

The window has 16 meters between the four sides, which gives 5 meters per side.

The graph of the function is attached.
