You bought your pig and it weighed 82 pounds. By fair your goal weight is 267 pounds. Your pig will gain 1 pound for every 3 pounds of feed. How much feed will you need to get your pig to it's goal weight? (show your work) (5) Feed costs $21.37 per 50 pound bag. How much will your feed cost be, to get your pig to it's goal weight? (5) MUST SHOW ALL WORK.
Number of feed = 555 pounds
Feed cost = $237.21
Further explanationThe main composition of algebraic expressions are:
• 1. phrases/terms
• 2. variable
• 3. constants
• 4. arithmetic operations
• 5. coefficients
• 6. exponent
Initial weight = 82 pounds
Goal weight = 267 pounds
The difference in weight that must be achieved :
[tex]\tt 267-82=185~pounds[/tex]
The pig will gain 1 pound for every 3 pounds of feed⇒ 1 pound weight=3 pounds of feed
The amount of feed must be given:
[tex]\tt 185~pounds~weight\times 3~pounds~feed=555~pounds~of~feed[/tex]
Feed costs $21.37 per 50 pound bag, so for 555 pounds :
[tex]\tt (555~pounds\div 50)\times \$21.37=\$237.21[/tex]

Explanation:
Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
PLEASE HELP ASAP
Thank you!!
Answer:
Yes. The two elements can combine to form different compounds.
Explanation:
Two elements can combine at different ratios.
Consider CO and CO₂. Both are made from carbon and oxygen. However, C and O combine at a 1:1 ratio in CO but at a 1:2 ratio in CO₂. CO is a fuel; it burns in the air. CO₂ does not burn in the air; it is used to put out fires and is found in extinguishers. CO and CO₂ are two distinct compounds.
There are many ways for the elements to combine with each other. As a result, the first twenty elements on the periodic table alone can produce a large number of compounds.
Assignment Summary For this assignment, you will construct a scientific model of the water cycle to show how water is recycled through an ecosystem. Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earth’s spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle. Large poster board Markers, crayons, or colored pencils Scissors Glue or tape Student Guide (continued) Step 5: Write a paragraph describing the water cycle. a) Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.
Answer:
the water cycle is a system that goes through evaporation then the water goes into the clouds and rains down as preparation

HCI is a strong acid. What particles would you expect to find in a solution of HCI(aq)?
HCI, H+ and Cl- particles
H+ particles only
H+ and Cl- particles
HCl particles only
it ionizes completely because it's a strong acid so no HCl particles will be found only H+ that reacts with H2O and Cl- so the 3rd option is correct

B. Na+l: 11 protons and 10 electrons
С. N-3.7 protons and 10 electrons
D. Al 3. 13 protons and 16 electrons
Answer:
Explanation:
O-2 means that there are 2 more electrons than protons. This one is incorrect.
Na + 1 is correct. 11 protons and 10 electrons.
N-3 is correct 7 protons and 10 electrons.
AL+3 is incorrect. It goes the other way 13 protons 10 electrons.

How do coastal sand dunes form in Florida?
Answer:
They are formed by windblown sand collecting around an obstruction. As organic matter is deposited by wind and waves, low herbs colonize the dune. As these plants collect more sand and organic matter, the dune increases in height becoming the fore dune.

in the equation 3x-3=18 what is x?
Answer:
x=7
Explanation:
3x-3=18
-3 moves over the 18 side and becomes +3.
18 + 3 =21
3x=21
now you need to divide 3 with 21 giving you 7
Answer:
The answer is seven bc X is seven.
A mixture consists of 28% oxygen, 14% hydrogen, and 58% nitrogen by volume. A sample of this mixture has a pressure of 4.0 atm in a 9.6 L container at 300 K temperature. This mixture is run through a gas filter, which removes the hydrogen from this system. The gas is placed back into the 9.6 L container. How many moles of gas are left in the container? A) 4.2 mol B) 2.6 mol C) 1.3 mol D) 3.9 mol
Answer:
C) 1.3 mol
Explanation:
Using gas law we can find the initial moles of the sample of the mixture, as follows:
PV = nRT
PV / RT = n
Where P is pressure: 4.0atm
V is volume: 9.6L
R is gas constant: 0.082atmL/molK
T is absolute temperature: 300K
And n are moles of the gas
PV / RT = n
4.0atm*9.6L / 0.082atmL/molK300K = n
n = 1.56moles of the mixture of the gas are present into the 9.6L container
Now, 14% of this gas is hydrogen that was removed of the system, that is:
1.56mol*14% = 0.22 moles of hydrogen are removed.
Thus, moles of gas that remains in the container are:
1.56mol - 0.22mol = 1.34mol.
Right answer is:
C) 1.3 molAnswer:
C = 1.3

What is Newton's 1-3rd laws of motion? Give examples for each
Answer:
In the first law, an object will not change its motion unless a force acts on it
In the second law, the force on an object is equal to its mass times its acceleration
In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

What is the difference between the atomic weight and the relative
atomic mass (RAM)?
Answer:
Relative and average atomic mass both describe properties of an element related to its different isotopes. However, relative atomic mass is a standardized number that's assumed to be correct under most circumstances, while average atomic mass is only true for a specific sample.

Explanation:
difference between fluids and nonfluids
Answer:
All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.
Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.
Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.
3. What is found around the roots of some plants that turns nitrogen from the form we cannot use to the form we can use?
Answer:
Bacteria
Explanation:
Some plants, specifically leguminous plants form a symbiotic relationship with certain bacteria species called NITROGEN-FIXING BACTERIA in their root nodules. In this relationship, the bacteria species e.g nitrosomonas, nitrobacter etc help the plants fix atmospheric nitrogen (N2) or ammonium compounds, which are forms of nitrogen that are unusable to the plant into nitrates, a usable form.
Therefore, BACTERIA are the organisms found around the roots of these set of plants (legumes) that turns nitrogen from the form we cannot use to the form we can use.
