One liter of paint covers 100 square feet. How many gallons of paint does it take to cover a room whose walls have an area of 80
mezya [45]
1 gallon is 3.78 L
100 sq feet needs 1 L
800 sq feet needs x

100/800 = 1/x
100x = 800
x = 800/100
x = 8 L

If you use the fact that 4 L = 1 gallon then you need 2 gallons of paint. I you use the more accurate 3.78 L then
1 gallon = 3.78 L
x gallon = 8 L

3.78 x = 8*1
x = 8/3.78
x = 2.12 gallons.
 
I guess you could say that 1 gallon and 1 L would do you.

What's the slope of the line passing through the point help​
scoray [572]

Answer:

the slope is 3/4

Step-by-step explanation:

The formula for slope is

m = (y2 - y1)/(x2 - x1)

The two points are given as (-1, 1) or (x1, y1), and (3, 4) or (x2, y2)

Plug those value into the formula and simplify

m = (4 - 1)/(3 - (-1))

    m = 3/(3 + 1)

        m = 3/4
