Answer:
its the second 1, where it shows a positive
Step-by-step explanation:
it says that you have $350 already so thats a positive because there is no negitive sign in front of $340
And its number two beacuse it going in a positive direction from 340
because you are going to be saving %60 so that would add to $340
15.34/0.59 = 26 songs bought
28 free songs
so...
26+28 = 54 songs in total
Hope this helps :)
Answer:
(a) The area is 0.03 square miles
(b) The population density is 12000 people per square miles
Step-by-step explanation:
Given
See attachment for complete question
Solving (a): Area of Orchid Hill (in square miles)
The dimension of the neighborhood is 4 blocks by 3 blocks
Since each block are of the same dimensions
The area is calculated as:
![Area = 4blocks * 3 blocks](https://tex.z-dn.net/?f=Area%20%3D%204blocks%20%2A%203%20blocks)
If
then:
![1\ block = \frac{1}{20} mile](https://tex.z-dn.net/?f=1%5C%20block%20%3D%20%5Cfrac%7B1%7D%7B20%7D%20mile)
![1\ block = 0.05mile](https://tex.z-dn.net/?f=1%5C%20block%20%3D%200.05mile)
So, we have:
![Area = 4blocks * 3 blocks](https://tex.z-dn.net/?f=Area%20%3D%204blocks%20%2A%203%20blocks)
![Area = 4 * 0.05 * 3 * 0.05](https://tex.z-dn.net/?f=Area%20%3D%204%20%2A%200.05%20%2A%203%20%2A%200.05)
![Area = 0.03mi^2](https://tex.z-dn.net/?f=Area%20%3D%200.03mi%5E2)
Solving (b): The population density of the neighborhood as people per square mile
From the question, we have:
![People = 360](https://tex.z-dn.net/?f=People%20%3D%20360)
--- calculated
So, the population density is:
![Density = \frac{People}{Density}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7BPeople%7D%7BDensity%7D)
![Density = \frac{360}{0.03}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7B360%7D%7B0.03%7D)
![Density = 12000](https://tex.z-dn.net/?f=Density%20%3D%2012000)
