<em>Answer:</em>
<em>1/36</em>
<em>Step-by-step explanation:</em>
<em>²⁾5/18 - ⁹⁾1/4 =</em>
<em>= 10/36 - 9/36</em>
<em>= 1/36</em>
A vertical pole(AB) 6 feet long casts a shadow(CB) 55 inches long as shown in the attached image. Since the angle of elevation of sun is
. We hav to find the value of
.
Firstly, we will change the dimensions of pole(in feet) to the dimension of shadow( in inches) . So, that the dimensions of pole and shadow are same.
Since, 1 feet = 12 inches.
6 feet =
inches.
Now, let us consider the triangle ABC in the attached image,
We have to find

= 
= 1.309

So we basically need to find 35% of 20. An easy way to find percents is to multiply by the decimal form of said percent. So, .35 x 20 = 7.
Brea will hit the ball approximately 7 times when she is at bat.
So
(x-4)^2=(x-4)(x-4)=x^2-4x-4x+16=x^2-8x+16
