Answer:The percent change in volume between cylinders A and B is 50%.
Step-by-step explanation:
we know that having similar triangles so the ratio of sides,area and volume are same.
we know that 
will be the area of triangle.
so 
so the ratio of the perimeter of two triangles will be
ratio of the perimeter=
<span>Volume = L * W * H cubic units
Surface Area = 2 * (LW + LH + WH) square units</span>
Answer: 118.1 and 118.08
Step-by-step explanation:
For tenths 118.1 and for hundredth it is 118.08
sqrt (5x - 9) - 1 = x
sqrt(5x - 9) = x + 1
Square both sides:_
5x - 9 = x^2 + 2x + 1
x^2 - 3x + 10 = 0
(x - 5)(x + 2) = 0
x = 5 or -2.
Lets look for for any extraneous solutions:-
x = 5 ; sqrt (5*5-9) - 1 = sqrt16 - 1 = 3 and x = 3 (right hand side of equation)
so x = 5 is a solution
x = -2: sqrt(5*-2 - 9) - 1 = sqrt (-19) - 1 and x = -2 so this is extraneous
Answer:- One solution x = 5
