We have to find the area of each wall and then multiply it by the number of gallons.
So the formula of the two walls are 2(26*9), which is 2(234) then simplified into 468.
Afterwards we have to multiply 468 * 250 and get 58500 sq ft
Ans:58500 sq ft
Fraction: 
Decimal: 0.308
Explanation:
means 4 ÷ 13. If you do that division, you get 0.3076 which can be rounded up to 0.308.
The equation that represents the line that is perpendicular is
3y + 5x = -42
The standard equation of a line in point-slope form is expressed as:

- m is the slope of the lne
- (x1, y1) is any point on the line.
- Given the equation y = 3/2x + 1, the slope of the line is 3/5
- The s<u>lope of the line perpendicular</u> is -5/3
Substitute the point (-12, 6) and the slope m = -5/3 into the equation above to have:

Hence the equation that represents the line that is perpendicular is
3y + 5x = -42

You didn't specify how big the festival is. so i can't find the answer.....but i will try
first let's devide 10,000 by 0.9 to see how many square metres we need, to fit 10,000 people
10,000÷0.9=11,111 square meters
we need atleast 11,111 meters of land for a safe festival
