37.8 to 0 and add 12.3 = 50.1 m is the total distance traveled.

Answer:

50.1 meters

Step-by-step explanation:

The elevator starts at the top floor of the building which is 37.8 meters tall. Therefore, from the top to the ground it travels 37.8 meters.

But then, the elevator continues going down all the way to the parking garage 12.3 meters underground.

Therefore, to determine the total distance traveled we are going to sum up these two quantities:

Total distance traveled = 37.8 + 12.3 = 50.1

The elevator traveled 50.1 meters

Answer:

1.107   =  r

Step-by-step explanation:

To solve this for r, do the following:

Add 10 to both sides, to isolate the r term on the left:  18r^(-8) = 8

Divide both sides by 18, to isolate r^(-8):   r^(-8) = 8/18

Invert both sides:  r^8 = 9/4

Take the natural log or both sides:

8 ln r = ln 9 - ln 4, or

8 ln r = 0.8109, so that ln r = 0.1014

to find r, raise e to the power ln r on the left and e to the power 0.1014 on the right:

  ln r           0.1014

e         =    e              =  1.107   =  r

Step-by-step explanation:

angle b = 71°

so, x + b = 180° ( linear pair )

x + 71° = 180°

x = 180° - 71°

x = 109°

Now, a + y = 180° ( <em>linear</em><em> </em><em>pair </em><em>)</em>

93° + y = 180°

y = 180° - 93°

y = 87°

<em>Hence</em><em>,</em><em> </em><em>the </em><em>value</em><em> of</em><em> x</em><em> </em><em>is </em><em>1</em><em>0</em><em>9</em><em>°</em><em> </em><em>and </em><em>y </em><em>is </em><em>8</em><em>7</em><em>°</em><em>.</em>
