Answer:
We conclude that the average American shower needs 2984.8 minutes and 6260.8 gallons of water during the year.
Step-by-step explanation:
We know that the average American shower lasts for 8.2 minutes and uses 17.2 gallons of water. A person showers once a day for a year.
We know that one year have 52 weeks, and one week have 7 days.
We calculate:
8.2 · 7 · 52= 2984.8 minutes.
17.2 · 7 · 52= 6260.8 gallons.
We conclude that the average American shower needs 2984.8 minutes and 6260.8 gallons of water during the year.
All I know is that you should multiply than add all of the products
Answer:
m∠z = 106°
Step-by-step explanation:
From the figure attached,
By exterior angle theorem,
m∠z = a + 68°
By linear pair theorem,
m∠a + 142° = 180°
m∠a = 180° - 142°
= 38°
Therefore, m∠z = 38° + 68°
= 106°
Answer:
d=20
Step-by-step explanation:
To find the distance between 2 points we use the distance formula
d = √(x2 - x1)²+(y2 - y1)²
The given points are (x1= -8, y1 = -6) and (x2 = 4, y2 = 10).
Substitute the given points into the distance formula.
d = √(4 + 8)²+(10 +6)²
d = √144+252
d= √400
d = 20
