<h3><u>Answer;</u></h3>

<em>16 half-cup servings of beans and 4 three oz. servings of shrimp</em>

<h3><u>Explanation and solution;</u></h3>

Let x = number of half-cup servings of beans  

Let y = number of 3 oz. servings of shrimp  

We will have 2 equations, one for carbs and one for calories  

7x + 9y = 148

30x + 190y = 1240  

30(7x + 9y) = 30(148)  

-7(30x + 190y) = -7(1240)  

210x + 270y = 4440  

-210x - 1330y = -8680

-1060y = -4240  

y = 4

7x + 9y = 148

7x + 9(4) = 148

7x + 36 = 148  

7x =  112

x = 16

Hence; X = 16 and Y= 4

List the layers contained in the atmosphere and describe what is in each layer.
lisabon 2012 [21]

Answer:

Exosphere -The exosphere layer is mainly composed of extremely low densities of hydrogen, helium, and several heavier molecules including nitrogen, oxygen, and carbon dioxide closer to the exobase. The atoms and molecules are so far apart that they can travel hundreds of kilometers without colliding with one another.

Thermosphere - The aurora (Northern Lights and Southern Lights) mostly occur in the thermosphere. The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. ... Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher.

Mesosphere- Most meteors burn up in the mesosphere. A type of lightning called sprites sometimes appears in the mesosphere above thunderstorms. Strange, high-altitude clouds called noctilucent clouds sometimes form in this layer near the North and South Poles.

Stratosphere-The stratosphere is the second major atmospheric layer above the troposphere, extending in altitude from about 8 to 30 miles high. No weather occurs in the stratosphere. The statosphere contains over 15% of the total mass of the atmosphere, and is where the ozone layer is located.

Troposphere-The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains 75% of the atmosphere's mass and 99% of the total mass of water vapour and aerosols.

i hope this helps, good luck :)
