Width of foil is
inches
<em><u>Solution:</u></em>
Given that area of the rectangle piece of foil is
square inches
Its length is
inches
To find: width of foil
<em><u>The area of rectangle is given as:</u></em>
To find the area of a rectangle, we multiply the length by the width
![\text{ area of rectangle}= length \times width](https://tex.z-dn.net/?f=%5Ctext%7B%20area%20of%20rectangle%7D%3D%20length%20%5Ctimes%20width)
<em><u>Substituting the given values in above formula,</u></em>
![11\frac{1}{4} = 4\frac{1}{2} \times width](https://tex.z-dn.net/?f=11%5Cfrac%7B1%7D%7B4%7D%20%3D%204%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20width)
Let us solve above expression to find width
![\frac{4 \times 11 + 1}{4} = \frac{2 \times 4 + 1}{2} \times width\\\\\frac{45}{4} = \frac{9}{2} \times width\\\\width = \frac{45}{4} \times \frac{2}{9}\\\\width = \frac{5}{2} = 2\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B4%20%5Ctimes%2011%20%2B%201%7D%7B4%7D%20%3D%20%5Cfrac%7B2%20%5Ctimes%204%20%2B%201%7D%7B2%7D%20%5Ctimes%20width%5C%5C%5C%5C%5Cfrac%7B45%7D%7B4%7D%20%3D%20%5Cfrac%7B9%7D%7B2%7D%20%5Ctimes%20width%5C%5C%5C%5Cwidth%20%3D%20%5Cfrac%7B45%7D%7B4%7D%20%5Ctimes%20%5Cfrac%7B2%7D%7B9%7D%5C%5C%5C%5Cwidth%20%3D%20%5Cfrac%7B5%7D%7B2%7D%20%3D%202%5Cfrac%7B1%7D%7B2%7D)
Therefore width of foil is
inches
Answer:
42
Step-by-step explanation:
87.5% of 48
= (87.5/100) x 48
=0.875 x 48
= 42
( 36 x³ - 96 x² + 48 x ) : ( 12 x ) = 3 x² - 8 x + 4
Answer: A ) 3 x² - 8 x + 4
Thank you.
