Answer:4
Step-by-step explanation:
2+2 = 4
Adding 2 in 2 gives us 4.
Answer:
30.4
Step-by-step explanation:
if you want the basic perimeter just add up all the sides
Graphs like these (lines) come in the form y = mx + b where m is the slope and b is the y intercept. Y intercept is where the graph intersects the y axis so the value would be 5
Answer:
The width of the frame must be 12 inches (15in by 12in)
Step-by-step explanation:
Given
See attachment for painting and frame
Required
Determine the dimension of the frame
To do this, we make use of the following scale ratio.
![Scale = Length : Width](https://tex.z-dn.net/?f=Scale%20%3D%20Length%20%3A%20Width)
For the painting,
![Scale = 20: 16](https://tex.z-dn.net/?f=Scale%20%3D%2020%3A%2016)
For the frame,
![Scale = 15: w](https://tex.z-dn.net/?f=Scale%20%3D%2015%3A%20w)
Since she wants to maintain the same ratio; both scale must be the same.
i.e.
![15 : w = 20 : 16](https://tex.z-dn.net/?f=15%20%3A%20w%20%3D%2020%20%3A%2016)
Express as fraction
![\frac{w}{15} = \frac{16}{20}](https://tex.z-dn.net/?f=%5Cfrac%7Bw%7D%7B15%7D%20%3D%20%5Cfrac%7B16%7D%7B20%7D)
![\frac{w}{15} = 0.8](https://tex.z-dn.net/?f=%5Cfrac%7Bw%7D%7B15%7D%20%3D%200.8)
Make w the subject
![w = 15 * 0.8](https://tex.z-dn.net/?f=w%20%3D%2015%20%2A%200.8)
![w = 12](https://tex.z-dn.net/?f=w%20%3D%2012)
<em>The width of the frame must be 12 inches i.e. 15in by 12in frame</em>
6.1 divided by 8 = 0.7625
