Answer:
2 gallons
Step-by-step explanation:
25% of 4 gallons is 1 gallons, which means that 75% of the hand sanitizer is not alcohol, and is 3 gallons. since that is the amount of not alcohol, and we want it to be 50% solution, it has to be 3 gallons of alcohol in total, and 3-1=2.

Equations which are never true
2.1 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Equation of a Straight Line
2.2 Solve 2x-5y-5 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2x-5y-5 = 0 and calculate its properties
Answer:
Only four numbers can be formed
Step-by-step explanation:
We are to make numbers greater than 10 and less than 25
Distinct digits should be there
As such all numbers lying between 10 and 25 are
11,12,.....24
Of these the conditions are only 2, 0, 1 , 8 should be used.
First digit cannot be 0 or 8 because we want two digit numbers between 10 and 25
So first digit can be either 1 or 2
If first digit is 1, second digit can be either 2 or 8 i.e. only 12, 18
If first digit is 2, second digit can be 0 or 1 cannot be 8 i.e. only 20 , 21
Only 4 numbers can be formed
the lines are perpendicular because they're crossing each other
