Answer:
5+i
Step-by-step explanation:
If you would like to find the fraction of packages of banana chips Sergio ate every day, you can calculate this using the following steps:
12 packages of banana chips ... 1 week = 7 days
x packages of banana chips = ? ... 1 day
12 * 1 = 7 * x
12 = 7 * x
x = 12 / 7
x = 1 5/7 packages of banana chips per day
The fraction would be 12/7 packages of banana chips per day.
It said here the temperature drops 6.5°C when an altitude increases 1 kilometer and the bottom of the troposphere is about 15°C
I guess the answer should be 8 / 9
Answer: 72%
Step-by-step explanation:
Set Jamal's original ring price = x
![x - x(0.2) = 2640\\x(1-0.2)=2640\\x(0.8)=2640\\x=\frac{2640}{0.8}=3300](https://tex.z-dn.net/?f=x%20-%20x%280.2%29%20%3D%202640%5C%5Cx%281-0.2%29%3D2640%5C%5Cx%280.8%29%3D2640%5C%5Cx%3D%5Cfrac%7B2640%7D%7B0.8%7D%3D3300)
Jamal's original ring price = $3300
Set Naomi's discount = y
![3300-3300(y)=924\\=3300(1-y)=924\\1-y=\frac{924}{3300} \\-y=\frac{924}{3300} -1\\y=1-\frac{924}{3300}=1-0.28=0.72](https://tex.z-dn.net/?f=3300-3300%28y%29%3D924%5C%5C%3D3300%281-y%29%3D924%5C%5C1-y%3D%5Cfrac%7B924%7D%7B3300%7D%20%5C%5C-y%3D%5Cfrac%7B924%7D%7B3300%7D%20-1%5C%5Cy%3D1-%5Cfrac%7B924%7D%7B3300%7D%3D1-0.28%3D0.72)
Naomi's discount is 0.72 = 72%
