5 gallons of water must be added.
10 gallons to start with
adding 'x' gallons of water final volume = 10 + x
.9 (10) = amount of vinegar
.1(10) = amount of water
amount of vinegar before and after water addition is constant
.9(10) = .6(10+x)
9 = 6 + .6x
3 = .6x
x = 5 gallons of water to be added

Number of sides= 10
Side length= 4.6 ( or in this case base)
161 sq inches / 10 = 16.1 area of triangle.
Area of triangle =(b<span>ase * </span>height)/2
16.1=(4.6*h)/2
multiply 16.1 by 2 (cancels the dividing the 2)
32.2=4.6*h
divid 32.2 by 4.6
<span>7 is the height of the triangle</span>
Answer:
1st one 6.4
Step-by-step explanation:
C^2= a^2 +b^2
