Rachal Corporation produces and sells a single product whose selling price is $150.00 per unit and whose variable expense is $57.00 per unit. The company's monthly fixed expense is $381,300.
Required:
a. Assume the company's monthly target profit is $9,300. Determine the unit sales to attain that target profit. Show your work!
b. Assume the company's monthly target profit is $18,600. Determine the dollar sales to attain that target profit. Show your work!

Answers

Answer:a) if the company's monthly target profit is $9,300, 4,200 units sales is needed

b) if the company's monthly target profit is $18,600, 4,300 units sales is needed

Explanation:

Using  The Contribution Margin Approach:  

Contribution Margin = Sales expense - variable expense

=$150.00 - $57.00

=$93

Contribution Margin Ratio= Contribution Margin/ sales expense  x 100

=93/150 x 100

= 62%

Assume the company's monthly target profit is $9,300.

A) Sales to attain the target profit = [(Fixed expenses + Target profit) ÷ Contribution Margin  ratio]

= ($381,300. + $9,300) ÷ 0.62

$390,600 ÷ 0.62

= $630,000

No. of units to be sold =Sales to attain the target profit/ selling price

$630,000/$150.00

=4,200 units

Assume the company's monthly target profit is $18,600

B) Sales to attain the target profit = [(Fixed expenses + Target profit) ÷ Contribution Margin  ratio]

= ($381,300. + $18,600 )÷ 0.62

$399,900 ÷ 0.62

= $645,000

No. of units to be sold =Sales to attain the target profit/ selling price

$645,000/$150.00

=4,300 units

O The water is heated by magma or hot rocks.
O The water is found in an impermeable layer.
O The water is under pressure naturally and no pump is needed.
O Amechanical pump must be installed to bring water to the surface.

Answers

Answer:

c-The water is under pressure naturally and no pump is needed.

Explanation:

Water from Artesian well is the water is under pressure naturally and no pump is needed.

What is Artesian well?

A well from which water flows under natural pressure without the need for pumping is known as an artesian well.

It is excavated or drilled whenever a gently sinking, permeable rock layer (such as sandstone) collects water at a level higher than the ground surface at the well site.

Water goes down into the aquifer (water-bearing layer) at the outcrop, but is blocked from escaping by impermeable rock layers above and below it (such as shale).

Water is forced to the surface of a well drilled down into the aquifer by the weight of the water (hydrostatic pressure) the pressure for the continuous up flow is maintained by the continued penetration of water into the aquifer at the intake region.

The ability to collect water is what distinguishes artesian wells.

The water is under pressure naturally and no pump is needed.

Pumping water isn't essential because there isn't any pressure in the water.

Hence, the correct option is C.

All of the following statements support the cell theory EXCEPT?

Answers

All of the following statements support the cell theory except all cells contain a nucleus. Thus, the correct option for this question is B.

What is the Cell theory?

The cell theory was proposed by two famous scientists. i.e. M.J. Schleiden and T. Schwann. There are three assumptions that fall under the cell theory.

All living organisms whether plants or animals are made up of cells. A cell is the smallest unit of all living organisms. It is the basic structural and functional unit of life.

Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells.

According to the three assumptions given above, the one which is not matched as per the options is that all cells contain a nucleus.

Therefore, the correct option for this question is B.

Cell theory is basically a biological theory first given in the mid-nineteenth century that states that living organisms are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.

According to the cell theory, all biological organisms are made up of cells; cells are the basic unit of life, and all life evolved from preexisting life.

The cell theory is now so well-established that it serves as one of biology's unifying principles.

Theodor Schwann proposed the classical cell theory in 1839. This theory is divided into three parts. The first section asserts that all organisms are made up of cells.

Answers

Answer:

If the mantle is made out of soft rock, then I think it would melt due to the heat, but if it was hard, it would just burn, so I firmly believe the rock is hard.

Explanation:

Mantle is a layer on planetary body which is made up of minerals. Mantle is solid as it is made up of heavy metals and solid rocks which makes it rigid.

What is Mantle?

A mantle is a layer inside a planetary body bounded by a core and on the above by a crust. Mantle is made up of rock or ices, and is generally the largest and most massive layer of any planetary body. Mantles are on the planetary bodies that have undergone differentiation by density.

The mantle is composed primarily of heavy metals, such as iron, nickel, and others. The state of the mantle was described as plastic. Many divide the mantle into further such as  the asthenosphere and lithosphere.

Mantle rocks are soft and able to move over the course of millions of years at great depth and pressure. The transfer of heat and material in the mantle helps to determine the landscape of the planet.

It is known that complex carbohydrates provide more sustained energy over time than simple sugars such as sucrose. Complex carbohydrates are polysaccharides, which are long chains of smaller sugar molecules bonded together. Simple sugars are monosaccharides that contain only one molecule.
Why do complex carbohydrates provide more energy over time versus simple carbohydrates?

Answers

Answer:

Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy. As complex carbohydrates have longer chains, they take longer to break down and provide more lasting energy in the body than simple carbohydrates

Explanation:

Answer:

A.) Complex carbohydrates have more chemical bonds to break than simple sugars, which takes longer for the body to digest and provides more units of energy for the body to use.

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy

Answers

Answer:

the other 60% of energy is stored away for further use in the cell

Explanation:

i hope im right

In the cell from glucose, 40% of energy is utilised to make ATP and the rest 60% is used in the process of making ATP. So 100% of glucose cannot be converted into ATP.

How does ATP form from glucose?

Glucose is a major source of energy. It has carbon, oxygen, and hydrogen . Due to the presence of oxygen, it can easily break down to produce energy during times of need.

Glucose is broken down into pyruvate by the process of glycolysis. In this process, the net gain is 2 ATP. Pyruvate converts into acetyl CoA. ATP is required in this process. Acetyl CoA enters the Krebs cycle.

To enter the mitochondria, ATP is required. Acetyl CoA enters the krebs cycle and electron transport chain.  The FADH₂ , NADH are broken. Proton gradient is formed due to the electron movement. Then ATP is formed due to the proton gradient across the inner mitochondrial membrane . To make ATP a lots of ATP have used in the process. So net gain of ATP of a glucose is 40% as rest 60% has used in the process .

Hence, 40% of energy of glucose make ATP, and the rest 60% is used in the process of making ATP

Challenge: In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:

6CO2 + 6H2O + light C6H12O6 + 6O2
C6H12O6 + 6O2 6CO2 + 6H2O + energy

How do these equations explain why the total amount of O2 and CO2 remains the same?

The total amount of O₂ and CO₂ remains the same because their 6 molecules of carbon formed glucose and the remaining 6 molecules of oxygen are released as by-products.

What is the difference between respiration and photosynthesis?

Green plants make their own food through a process called photosynthesis, which transforms light energy into chemical energy.

Living things use the process of respiration to change oxygen and glucose into carbon dioxide and water, which releases a significant quantity of energy.

There are two stages to photosynthesis: light reaction and dark reaction. Inhalation and exhalation are the two phases of respiration. Because photosynthesis depends on light, it only occurs during the day. No organism can survive without breathing, which is a constant activity.

Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells

Answers

Answer:

The reduction of chromosomes in the gametes is necessary to make sexual reproduction possible, in which each parent contributes half of their chromosomes and in fertilization a cell with the complete amount of chromosomes is produced, the zygote.

Explanation:

The reduction of chromosomes to form gametes is done by meiosis, a reductive cell division. Sex cells or gametes are haploid cells, i.e. with half the chromosome charge, as each parent must contribute a gamete in the reproductive process.

The union of the parents' gametes is called fertilization and its product is the zygote, whose chromosome charge is complete or diploid.

For a diploid zygote to be formed, it is necessary for the sex cells or gametes to be haploid, or with half of the chromosomes of the species..

The genetic content built of proteins and nucleic acid found in the nucleus of cells are called chromosomes.

The reduction of the chromosome is essential for sexual reproduction.

In this sort of reproduction gametes from each parent fuse to form offspring.

Each parent provides half the number of chromosomes (n) to form a complete offspring with the total set of chromosomes (2n).

In the process of gamete formation chromosomes, get halved due to meiosis.

The reproductive gametes from both the parent combine via fertilization and form the diploid offspring.

Therefore for a diploid offspring to be formed the gametes need to be haploid.

The process of cell division by which most of cells divide for growth is called mitosis.

In this process, each cell called mother cell divides to form two identical daughter cells. The daughter cells have the same number of chromosomes as mother cell. It helps in growth and repair of tissues in organisms.

Specific cells of reproductive organs or tissues in animals and plants divide to form gametes., which after fertilisation give rise to offspring.

They divide by a different process called MEIOSES.

Which involves two consecutive divisions. When a cell divides by meiosis it produces four new cells instead of just two .

The new cells only have half the number of chromosomes than that of the mother cells.
