Answer to this math question?
Gennadij [26K]

Answer:

Option 4

Step-by-step explanation:

<h3>Volume of Cone:</h3>

                h = x units

   diameter = x units

                 r = (x/2) units

    \sf \boxed{\text{ \bf Volume of cone = $\dfrac{1}{3} \pi r^2h$}}

                                   \sf =\dfrac{1}{3}*\pi * (\dfrac{x}{2})^2*x\\\\=\dfrac{1}{3}*\pi*\dfrac{x^2}{4}*x\\\\=\dfrac{1}{12}\pi x^3

In segment AC, the midpoint is B. if segments AC = 5x-9 and AB= 2x what is the measure of AC? Can you show their work on paper o
vodka [1.7K]

Answer:

The answer to your question is: AC = 36

Step-by-step explanation:

Data

Segment AC with midpoint = B

AC = 5x - 9

AB = 2x

AC = ?

Process

           total length = AC  but B is the midpoint so AB + AB = CA

                                                                                  2AB = CA

                Substitution        2(2x) = 5x - 9

                                             4x = 5x - 9

Solve for x                           4x - 5x = -9

                                             -1x = -9

                                              x = -9/-1

                                             x = 9

Finally,            AC = 5x - 9

                             = 5(9) - 9

                             = 45 - 9

                             = 36

x+12=-5

we need to get x by itself so we minus 12 in both sides

x=-12-5

-12-5 we get -17 so

x=-17
