Answer:
C
Step-by-step explanation:
Use sine rule
17/sin130=5/sinB
(5×sin130)÷17=sinB
sinB=0.2253017892
B=sin^-1ans above
=13.4
A=(130+13) subtracted from 180=37°
a/sin37=17/sin130
=13.4
Cubic inch means we are dealing with volume.
So,
Calculate the volume of both boxes.
1. 3x9x12 = 324 cubic inches
2. 2x8x9 = 144 cubic inches
First box costs $6 for 324 cubic inches, so if you divide 6 by 324 you will get the price for 1 cubic inch of the box.
6/324 = $0.018518518518519
2.
Second box costs $4.50 for 144 cubic inches.
4.5/144 = $0.03125
Subtract the cheaper one from the more expensive one to find the difference.
0.03125 - 0.018518518518519 = 0.012731481481481
The difference in price per cubic inch is
$0.012731481481481
Or about 1.3 cents.
Because 44 is a bigger number than 4 it is 11 times bigger so the difference is larger than a proportional number

Step-by-step explanation:
Given
![l = 4h](https://tex.z-dn.net/?f=l%20%3D%204h)
Required
Represent the scenario on a graph
When h = 0
![l = 4h= 4 * 0 = 0](https://tex.z-dn.net/?f=l%20%3D%204h%3D%204%20%2A%200%20%3D%200)
When h = 1
![l = 4 * 1 = 4](https://tex.z-dn.net/?f=l%20%3D%204%20%2A%201%20%3D%204)
When h = 2
![l = 4 * 2 = 8](https://tex.z-dn.net/?f=l%20%3D%204%20%2A%202%20%3D%208)
When h = 3
![l = 4 * 3 = 12](https://tex.z-dn.net/?f=l%20%3D%204%20%2A%203%20%3D%2012)
When h = 4
![l = 4 * 4 = 16](https://tex.z-dn.net/?f=l%20%3D%204%20%2A%204%20%3D%2016)
When h = 5
![l = 4 * 5 = 20](https://tex.z-dn.net/?f=l%20%3D%204%20%2A%205%20%3D%2020)
So, we have:
![(h,l) = (0,0)](https://tex.z-dn.net/?f=%28h%2Cl%29%20%3D%20%280%2C0%29)
![(h,l) = (1,4)](https://tex.z-dn.net/?f=%28h%2Cl%29%20%3D%20%281%2C4%29)
![(h,l) = (2,8)](https://tex.z-dn.net/?f=%28h%2Cl%29%20%3D%20%282%2C8%29)
![(h,l) = (3,12)](https://tex.z-dn.net/?f=%28h%2Cl%29%20%3D%20%283%2C12%29)
![(h,l)= (4,16)](https://tex.z-dn.net/?f=%28h%2Cl%29%3D%20%284%2C16%29)
![(h,l)= (5,20)](https://tex.z-dn.net/?f=%28h%2Cl%29%3D%20%285%2C20%29)
