Answer:
192
Step-by-step explanation:
12:49 - 12:17 = 32min
if 60min = 360°
32min = ?
<u>3</u><u>2</u><u>×</u><u>3</u><u>6</u><u>0</u>
60
=192°

It is in the lowest form already
Answer:
![9\text{ cm}](https://tex.z-dn.net/?f=9%5Ctext%7B%20cm%7D)
Step-by-step explanation:
We can write the following proportion:
![\frac{\text{old perimeter}}{\text{scaled perimeter}}=\frac{\text{old scale factor}}{\text{new scale factor}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bold%20perimeter%7D%7D%7B%5Ctext%7Bscaled%20perimeter%7D%7D%3D%5Cfrac%7B%5Ctext%7Bold%20scale%20factor%7D%7D%7B%5Ctext%7Bnew%20scale%20factor%7D%7D)
We know that the original perimeter of the Pentagon is 921 feet. So, substitute 921 for "old perimeter."
We are going to use a scale of 3 cm = 307 feet. Since the 307 feet corresponds to the original perimeter, we are going to substitute 307 for "old scale factor" and 3 for "new scale factor."
This gives us:
![\frac{921}{x}=\frac{307}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B921%7D%7Bx%7D%3D%5Cfrac%7B307%7D%7B3%7D)
So, to find our scaled perimeter, we just need to find x.
Cross multiply:
![307x=2763](https://tex.z-dn.net/?f=307x%3D2763)
Divide both sides by 307:
![x=9](https://tex.z-dn.net/?f=x%3D9)
In other words, the total perimeter of Sawyer's drawing will be 9cm.
And we're done!
Answer:
Elias is not correct. The new rectangle will be an enlargement because the scale factor is greater than 1. To be a reduction, the scale factor must be between 0 and 1.
