Answer:
3.9 km
Step-by-step explanation:
Arc length is (pi*r)/4=(pi*5)/4=3.9 km. Love from Gauthmath.
G = {(-1, 7), (-8, 2), (0, 0), (6, 6)}
Range of G = {0, 2, 6, 7}
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
10= 30 degrees 30+90= 120
11= 60 degrees 180-120= 60
12= 60 degrees 180-120 = 60
13= 120 degrees 180-60= 120
