Explanation:
Simple conversions
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]

A radioactive nucleus can change from one element to another. How does this happen?
A radioactive decay is occurring by the emission of charged particles such alpha or beta to form a new stable atom with changes mass number and atomic number.
What is radioactive decay?Heavy unstable radioactive elements undergo nuclear decay by which they form a stable isotope or new atom with changed atomic number. There are two types of nuclear decays mainly. They are alpha decay and beta decay.
During alpha decay isotopes with higher mass number undergo alpha emission and forming a new species with mass number reduced by 4 units and atomic number reduced by 2 units.
In the case of beta- decay, electrons are emitted from the atom and then forming a new atom with atomic number increased by one unit. For an electron capture process, an electron is captured to the atom forming an element with atomic number reduced by one.

6. Which of the following molecules has a central atom with precisely two unshared
pairs of electrons?
methane, CH4
ammonia, NH3
hydrocyanic acid, HCN
water, H20
CLEAR ALL
Answer:
water, H20
Explanation:
From the given choices, only water has two unshared or lone pairs of electrons in its central atom.
The formula of water is:
H₂O
H is hydrogen with 1 electron
O is oxygen with 8 electrons and 6 valence electrons
To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.
The remaining 4 gives the two lone pairs.

What makes Carbon-14 so useful in “carbon dating” or “radiodating”?
Answer:
Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon. ... The carbon-14 method was developed by the American physicist Willard F. Libby about 1946.

Many plants in rainforests have leaf tips that come to a point, so precipitation drains off the leaf. This helps to keep the plant safe from harmful germs. Based on this info, what resource is prevalent in a rainforest?
Answer:
rainfall/water
Explanation:
The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.
Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.
Which statement describes the water gas particles in the air above the cup compared with the water liquid
particles in the cup?
The partides move faster and are closer together
The particles move faster and are far apart
The particles move slower and are closer together
The particles move slower and are far apart
Answer:
The particles move faster and are far apart
Explanation:
A substance may exist in three states of matter; solid, liquid and gas.
In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.
In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.
In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.
Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.
4. How does the
productivity of
photosynthesis affect the
productivity of cellular
respiration?
Answer: it’s the chemicals between the biological
Explanation:
The productivity of photosynthesis affect the productivity of cellular respiration by providing energy.
What is photosynthesis?Photosynthesis is a process where plants prepare their food in the presence of sunlight.
Photosynthesis process chemically illustrated as :
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
From the above it is clear that carbohydrate is produced in the photosynthesis process and this carbohydrate provide energy to the plant for the completion of another chemical process. So, for the cellular respiration plants use this energy.
Hence, the productivity of photosynthesis directly affect the productivity of cellular respiration.
