The projected T. rex is about

dolphi86 [110]

Answer: $scale\ factor=230$

Step-by-step explanation:

You need to analize all the information given in the exercise.

You know that the actual height of the T-rex on the projector lens is the following:

$actual\ height=2\ cm$

The height of the projected T-rex is:

$projected\ height=4.6\ m$

Make the conversion from meters to centimeters:

$projected\ heigth=(4.6\ m)(\frac{100\ cm}{1\ m})\\\\projected\ heigth= 460\ cm$

Therefore, the scale factor will be:

$scale\ factor=\frac{projected\ heigth}{actual\ heigth}$

Finally, you must substitute values into the equation and then you must evaluate in order to find the scale factor of the projection. You get that this is:

$scale\ factor=\frac{460\ cm}{2\ cm}\\\\scale\ factor=230$

Determine if the segment X is half the length, double the length, two thirds the length, or the same length as segment Y.

Ipatiy [6.2K]

The right answer is The Same Length.
The triangle displayed is Isosceles. The explanation of this statement is the fact that the Line which is making a right angle it is also the one that slices the segment into equal segments. Mathematically speaking, in our triangle the
Median is perpendicular on the segment from which results that the triangle is Isosceles and x = y.
