Please help with my question it is the millers shower uses 25 gallons of water for a 10 min shower. Now how many gallons of wate
klasskru [66]
Answer: The Millers need 15 gallons of water for 6 minutes.


Lets start by finding how much water is needed for 1 min shower. 
<span>
25 gallons of water is used for 10 min shower:

</span>10 mins = 25 gallons <span>

To find 1 min shower, we will divide the 25 gallons of water by 10. 
</span><span>
10 mins = 25 gallons            </span>← Divide by 10 on both sides<span>
÷ 10           ÷ 10
1 min = 2.5 gallons

Now that we know the Millers need 2.5 gallons for every 1 minute of shower, we can find 6 minutes of shower by multiplying by 6.

1 min = 2.5 gallons</span>         ← Multiply 6 on both sides<span>
   x6           x6
6 min = 15 gallons

Answer: The Millers need 15 gallons of water for 6 minutes.

a rectangle plot measure 20ft. by 30ft. A 3-ft.-wide sidewalk surrounds it.Find the area of the sidewalk.
goldenfox [79]
Area of a rectangle = length (l) * width (w)
A = 30ft * 20ft
A = 600 sq ft

Now the width of a sidewalk that surroundeds it = 3 ft
so now the area of the rectangle with sidewalk= 30+3ft * 20+3ft
A = (33*23) ft
A = 759 sg ft

Area of the sidewalk = 759 - 600
A = 159 sq ft

Step-by-step explanation:

Just plug in each value in the table in as x so when you plug in -2 that would be 3(-2)^2.  -2x-2=4. 4x3=12. :)
