Answer:
1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
x is the amount of sodium in 1oz of chips.
y is the amount of sodium in 1 cup of soda.
Bryan ate 4 oz of chips and drank 1 cup of soda for a total of 600mg of sodium.
This means that
, also ![y = 600 - 4x](https://tex.z-dn.net/?f=y%20%3D%20600%20-%204x)
Jadyn ate 1 oz of chips and drank 4 cups of soda for a total of 300mg of sodium.
This means that:
![x + 4y = 300](https://tex.z-dn.net/?f=x%20%2B%204y%20%3D%20300)
From the first equation, we have that
. So
![x + 4(600 - 4x) = 300](https://tex.z-dn.net/?f=x%20%2B%204%28600%20-%204x%29%20%3D%20300)
![x + 2400 - 16x = 300](https://tex.z-dn.net/?f=x%20%2B%202400%20-%2016x%20%3D%20300)
![15x = 2100](https://tex.z-dn.net/?f=15x%20%3D%202100)
![x = \frac{2100}{15}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B2100%7D%7B15%7D)
![x = 140](https://tex.z-dn.net/?f=x%20%3D%20140)
![y = 600 - 4x = 600 - 4*140 = 40](https://tex.z-dn.net/?f=y%20%3D%20600%20-%204x%20%3D%20600%20-%204%2A140%20%3D%2040)
1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.
Answer:
The surface is a cylindrical surface with radius 7 units
Step-by-step explanation:
The equation is properly written as:
![\rho^{2} (sin^{2} \phi sin^{2} \theta + cos^{2} \phi) = 49](https://tex.z-dn.net/?f=%5Crho%5E%7B2%7D%20%28sin%5E%7B2%7D%20%5Cphi%20sin%5E%7B2%7D%20%5Ctheta%20%2B%20cos%5E%7B2%7D%20%5Cphi%29%20%3D%2049)
The above equation takes the form ![y^{2} + z^{2} = r^{2}](https://tex.z-dn.net/?f=y%5E%7B2%7D%20%2B%20z%5E%7B2%7D%20%3D%20r%5E%7B2%7D)
Where ![y^{2} = \rho^{2} sin^{2} \phi sin^{2} \theta](https://tex.z-dn.net/?f=y%5E%7B2%7D%20%3D%20%5Crho%5E%7B2%7D%20sin%5E%7B2%7D%20%5Cphi%20sin%5E%7B2%7D%20%5Ctheta)
![y = \rho sin \phi sin \theta](https://tex.z-dn.net/?f=y%20%3D%20%5Crho%20sin%20%5Cphi%20sin%20%5Ctheta)
and ![z^{2} = \rho^{2}cos^{2} \phi](https://tex.z-dn.net/?f=z%5E%7B2%7D%20%3D%20%5Crho%5E%7B2%7Dcos%5E%7B2%7D%20%20%5Cphi)
![z = \rho cos \phi](https://tex.z-dn.net/?f=z%20%3D%20%5Crho%20cos%20%5Cphi)
![r^{2} = 49](https://tex.z-dn.net/?f=r%5E%7B2%7D%20%3D%2049)
r = 7 units
The surface is a cylindrical surface with radius 7 units
Answer:
Acute Isosceles triangle
Step-by-step explanation:
Acute Isosceles triangles are the triangles with all their internal angles being acute angles and only two sides equal to each other in length.
She can make 12 pizzas because 24 divided by 8 is 3. And if u multiply 3 by the number of packages (4) you will get 12
B = a+c AND b= c+a
SO the second choice and fifth choice
