The answer is D
Step-by-step explanation:
Alexis can wash a total of 14 windows in 1 hour
<h3><u>Solution:</u></h3>
Given that Alexis washes
windows in
hours
<u><em>To find: </em></u>number of windows washed in one hour
To simplify the calculations we will convert the given mixed fraction to improper fraction
![\begin{array}{l}{=10 \frac{1}{2}} \\\\ {=\frac{2 \times 10+1}{2}} \\\\ {=\frac{21}{2}=10.5}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%3D10%20%5Cfrac%7B1%7D%7B2%7D%7D%20%5C%5C%5C%5C%20%7B%3D%5Cfrac%7B2%20%5Ctimes%2010%2B1%7D%7B2%7D%7D%20%5C%5C%5C%5C%20%7B%3D%5Cfrac%7B21%7D%7B2%7D%3D10.5%7D%5Cend%7Barray%7D)
Hence, to wash 10.5 windows, Alexis takes 0.75 hours
Let "n" be the number of windows washed in 1 hour
10.5 windows ⇒ 0.75 hours
"n" windows ⇒ 1 hour
By cross-multiplication we get,
![n \times 0.75 = 10.5 \times 1](https://tex.z-dn.net/?f=n%20%5Ctimes%200.75%20%3D%2010.5%20%5Ctimes%201)
![n = \frac{10.5}{0.75} \\\\n = 14](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B10.5%7D%7B0.75%7D%20%5C%5C%5C%5Cn%20%3D%2014)
Thus Alexis can wash 14 windows in one hour

Step-by-step explanation:
yes
Sum of angles In all triangles are 180....line DAC is horizontal and therefore is 180 degrees ....so minus 180 degrees from 105 and you get 75 degrees....and since the sum of all angles in a triangle is 180...add 75 and 67 which would be 142 degrees ...then minus 142 from 180 degrees to get 38 degrees for x
