Answer:

^7C_4 = 35

Step-by-step explanation:

We are given the following information in the question:

We have to evaluate:

Formula:

^7C_4\\^n C_x = \displaystyle\frac{n!}{(n-x)!x!}\\\\^7C_4 = \displaystyle\frac{7!}{(7-4)!4!} =\frac{7!}{3!4!} =\frac{7.6.5.4.3.2.1}{3.2.1.4.3.2.1} = 35

Thus, the is values is 35

I need homework help! Its proportions, but the thing is, I'm terrible at them. All I know is that is/of=x/100.

19)  15/a = 3/2 

Start by cross multiplying....

3a = 30 

Divide both sides 3 

a = 10 

21)   2/7 = 4/d 

        2d = 28
       
        d= 14 

23)  8/p = 3/10

       
80 = 3p
         p = 26.66

25)  2 / -5 = 6/t
        2t = -30

      t = -15

I need helpppp (10 points )

Answer:  The flagpole is about 22.3 feet tall.

This is roughly the size of a two story building, assuming each floor is 10 feet or so.

Since this height is under 25 ft, this flagpole is in compliance with the regulation.

=====================================================

Work Shown:

The horizontal leg of the triangle is 36 ft. This is the adjacent leg to the reference angle 25 degrees.

The vertical leg of the triangle is x-5.5, and this leg is the opposite side to the reference angle 25 degrees.

Use the tangent rule to connect the opposite and adjacent sides.

Solve for x.

tan(angle) = opposite/adjacent

tan(25) = (x-5.5)/36

36*tan(25) = x-5.5

x-5.5 = 36*tan(25)

x = 36*tan(25)+5.5

x = 22.28707569358

x = 22.3 ft is the approximate height of the flagpole

Make sure your calculator is in degree mode.

The height is not over 25 ft, so this flagpole meets the requirements.
