We have two similar triangles, the one as a whole and the one inside of it. To calculate the height of the flagpole we can set up a proportion. First calculate the length of the base of the smaller triangle.

16.60 - 12.45 = 4.15m

The height is 1.65m, set up a proportion:

\sf\dfrac{1.65}{4.15}=\dfrac{x}{16.60}

Cross multiply:

\sf 27.39=4.15x

Divide 4.15 to both sides:

\sf x=\boxed{\sf 6.6m}

So the height of the flagpole is 6.6 meters tall.

Solve for x 11x+4<15 OR 12x−7>−25
never [62]

Isolate the x in both cases. What you do to one side, you do to the other.


11x + 4 < 15


Subtract 4 from both sides


11x + 4 (-4) < 15 (-4)


11x < 11


isolate the x, divide 11 from both sides


11x/11 < 11/11


x< 1


x < 1 is your answer for the first one

-------------------------------------------------------------------------------------------------------------------


Again, isolate the x.


12x - 7 > -25


Add 7 to both sides


12x - 7 (+7) > -25 (+7)


12x > -18


Isolate the x, divide 12 from both sides


12x/12 > -18/12


x > -1.5 is your answer for the second one.

Artemon [7]

Answer:

9.193259%

Step-by-step explanation:

In order to obtain the percentage of military members in the reserves who are​ Black, we will have to multiply the percentage of Black military members in the reserve by the percentage of military members in the reserve. This is calculated as follows:

Military members in the reserves who are​ Black (%) = 77.1771​% × 11.9119​%

                                                                                      = 9.193259%

Therefore, he percentage of military members in the reserves who are​ Black is 9.193259% .

Example

For example, let assume the total number of active members in the military is 100.

To obtain the number of military members who are in the reserves, we multiply 77.1771​% by 100. This gives us 78 approximately.

To obtain the number of military members in the reserves who are​ Black, we multiply 11.9119​% by 78 we got above who are active military members in the reserves. This gives us 9 members approximately.

I wish you the best.
