Answer: the answer is c
Step-by-step explanation:
-6x+9=-5x+5
-x+9=5
-x=5-9
-x=-4
x=4
Let
a---------> length of one of the two congruent sides of the triangle
we know that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)
so
(a+a) > 8
2a > 8
a> 4
Rounded to the nearest tenth, <span>the smallest possible length of a is 4.1

the answer is
4.1 units
To find the volume of the cylinder we multiply the area of the face by the height of the cylinder. Area pi*r^2
First find area
768in^3/3in = 256in^2
Pi*r^2 = 256
r^2 = 256 / pi
radius = root of 256/pi
Hence radius = 9.027033337 in
To check answer
Pi*9.027033337^2 * 3in = 768in^3
Finalized answer to 2 d.p
Radius = 9.03 in
