We have the following points and their coordinates:

We must compute the distance ST between them.
The distance ST between the two points is given by:
![ST=\sqrt[]{(x_S-x_T)^2+(y_S-y_T)^2_{}},](https://tex.z-dn.net/?f=ST%3D%5Csqrt%5B%5D%7B%28x_S-x_T%29%5E2%2B%28y_S-y_T%29%5E2_%7B%7D%7D%2C)
where (xS,yS) are the coordinates of the point S and (xT,yT) are the coordinates of the point T.
Replacing the coordinates of the points in the formula above, we find that:
![\begin{gathered} ST=\sqrt[]{(-3_{}-(-2)_{})^2+(10_{}-3_{})^2_{}}, \\ ST=\sqrt[]{1^2+7^2}, \\ ST=\sqrt[]{50}\text{.} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20ST%3D%5Csqrt%5B%5D%7B%28-3_%7B%7D-%28-2%29_%7B%7D%29%5E2%2B%2810_%7B%7D-3_%7B%7D%29%5E2_%7B%7D%7D%2C%20%5C%5C%20ST%3D%5Csqrt%5B%5D%7B1%5E2%2B7%5E2%7D%2C%20%5C%5C%20ST%3D%5Csqrt%5B%5D%7B50%7D%5Ctext%7B.%7D%20%5Cend%7Bgathered%7D)
Answer: ST = √50
Answer:
a) 4106.25 gallons
b) $46
Step-by-step explanation:
We are given the following in the question:
Leakage rate of faucet = 1 oz per minute
Cost of water = $11.20 per 1000 gallons
1 gallon = 128 oz
a) water are wasted in a year
1 hour = 60 minutes
1 day = 24 hours
1 year = 365 days

Amount of water wasted =

Thus, 4106.25 gallons of water is wasted every year.
b) additional money spent

Thus, approximately $46 is the additional money spent on water bill.
Answer:
x = 3
Step-by-step explanation:
49 - 19 = 30
-2x - 12x = 10x
30 / 10 = 3
