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.
The value of k is 400 points.
If the player fails to complete 100 tasks, then they lost 200 points. At the end of the game, they had 200 points.
We can write and solve the following equation to determine where they started.
x - 200 = 200
x = 400
The equation between the number of days remaining and number of hours is given as y= -5x+50.
<h3>How to illustrate the equation?</h3>
Let y be the number of days remaining and x be the no.of hours.
From the graph the slope of the line is given by m.
m=(y2 - y1)/(x2 - x1)
m=(30 - 40)/(4 - 2)
m= -10/2 = -5.
The above slope is in between points 2 and 4. As the line has a constant rate of growth the slope is the same between any points of the line.
Therefore the equation between the no.of days remaining and no.of hours is given by
y=mx +c.
y=-5x+c
Now to find the value of c. This can be determined by substituting the x and y values at a particular instant. For x=0,y=50. Therefore by these values, we get,
50= -5(0)+c
c=50.
Therefore the relation between the number of days remaining and number of hours is given as y= -5x+50.
