Answer:
The estimated area is ![416\frac{13}{16}\ ft^{2}](https://tex.z-dn.net/?f=416%5Cfrac%7B13%7D%7B16%7D%5C%20ft%5E%7B2%7D)
Step-by-step explanation:
we know that
To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3
step 1
Convert the dimensions to an improper fractions
![9\frac{3}{4}\ ft=\frac{9*4+3}{4}=\frac{39}{4}\ ft](https://tex.z-dn.net/?f=9%5Cfrac%7B3%7D%7B4%7D%5C%20ft%3D%5Cfrac%7B9%2A4%2B3%7D%7B4%7D%3D%5Cfrac%7B39%7D%7B4%7D%5C%20ft)
![14\frac{1}{4}\ ft=\frac{14*4+1}{4}=\frac{57}{4}\ ft](https://tex.z-dn.net/?f=14%5Cfrac%7B1%7D%7B4%7D%5C%20ft%3D%5Cfrac%7B14%2A4%2B1%7D%7B4%7D%3D%5Cfrac%7B57%7D%7B4%7D%5C%20ft)
step 2
Find the area of one wall
![(\frac{39}{4})*(\frac{57}{4})=\frac{2,223}{16}\ ft^{2}](https://tex.z-dn.net/?f=%28%5Cfrac%7B39%7D%7B4%7D%29%2A%28%5Cfrac%7B57%7D%7B4%7D%29%3D%5Cfrac%7B2%2C223%7D%7B16%7D%5C%20ft%5E%7B2%7D)
step 3
Multiply the area of one wall by 3
![(3)*\frac{2,223}{16}=\frac{6,669}{16}\ ft^{2}](https://tex.z-dn.net/?f=%283%29%2A%5Cfrac%7B2%2C223%7D%7B16%7D%3D%5Cfrac%7B6%2C669%7D%7B16%7D%5C%20ft%5E%7B2%7D)
step 4
Convert to mixed number
![\frac{6,669}{16}=\frac{6,656}{16}+\frac{13}{16}=416\frac{13}{16}\ ft^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B6%2C669%7D%7B16%7D%3D%5Cfrac%7B6%2C656%7D%7B16%7D%2B%5Cfrac%7B13%7D%7B16%7D%3D416%5Cfrac%7B13%7D%7B16%7D%5C%20ft%5E%7B2%7D)
16, 5, 25, 6, 36, 7, 49, 8, 64, 9, 81, 10, 100
The pattern is starting at 1 then squaring it. Then, you move to the next number after one, then square it, and so on.
Opposite sides are congruent and have the same slope.
Post the image it would help a lot.
Answer:
I would use a bar graph so the bottom of the graph could be the number of books, and the left could be the price. the higher the bar is, the higher the price. It is easy to compare heights of the bars from just looking at the graph.
