Answer:

253/4 or 63 1/4

Step-by-step explanation:

You have to first turn your whole numbers into fraction, and to do that you simply just put a 1 under the whole number (in this case it's 23) which would look like this: 23/1. Then multiply the fractions (11/4•23/1) which would be 253/4. You can simplify and turn it into a mixed fraction (I would highly recommend doing that) but it is an option

253/4 at its simplest form would be 63 1/4

A source of laser light sends rays AB and AC toward two opposite walls of a hall. The light rays strike the walls at points B an
____ [38]

Answer: 70  meters.

Step-by-step explanation:

Observe the figure attached.

The distance between the walls is:

DE=AD+AE

<em />

Both triangles are right triangles. Therefore, you can calculate the distance  between the walls as following:

- Calculate the distance AD:

cos\alpha=\frac{adjacent}{hypotenuse}\\\\cos(60\°)=\frac{AD}{60}\\AD=30m

- Calculate the distance AE:

tan\beta =\frac{opposite}{adjacent}\\\\tan(45\°)=\frac{40}{AE}\\\\AE=\frac{40}{tan(45\°)}\\\\AE=40m

Therefore the distance between the walls is:

DE=30m+40m=70m
