My favorite thing at the space art exhibit was a room full of robots made from nuts, bolts, and car parts. Blinking, talking. They posed the robots in front of paintings from of all different kinds of real and imaginary planet landscapes such as Jupiter and Mars. Some of the robots were fierce, and some wore makeup. I also liked the “space city” that some artist constructed by cutting small holes in of all kinds of colorful tents and lighting them from within.

Tina can paint a room 1.5 times faster than Joey can. If they work together, they can paint a room in 6 hours. How long would it take the slower person working alone to paint the room?

To answer this problem, let us define that:

x = amount of time Joey can paint a room in hours

1.5 x = amount of time Tina can paint a room in hours

Each person can complete 1 job in the specified amount of
time.

1 job / x hours = rate of Joey

1job / 1.5 x hours = rate of Tina

By adding the two, they can paint the room (1 job) in 6
hours. Therefore:

(1 / x) + (1 / 1.5 x) = 1 / 6

Multiplying whole equation with 6 (x) (1.5 x):

6 (1.5 x) + 6 x = x (1.5 x)

9 x + 6 x = 1.5 x^2

Dividing both sides with x:

15 = 1.5 x

x = 10 hours

Therefore the time it will take Tina, the slower person, is
1.5x = 15 hours

You have been called to attend a birth and are the only healthcare provider responsible for the management of the newborn in the room. When should you first call for additional help?

The first call for additional help should be done before birth. If there is any potential risk factor of neonatal resuscitation, then help is needed.

EXPLANATION

First additional help is needed when the healthcare identifies factor risks of neonatal resuscitation. Neonatal resuscitation is intervention after the baby is born. This additional help is to support the heartbeat and its breathing.

Inside the womb, the baby got oxygen from the placenta. Placenta also supplies nutrition to the blood and remove carbon dioxide. After the baby is born, that function is replaced by the lungs. Baby’s lungs will have to remove the carbon dioxide and supply oxygen to the blood. This transition will happen when the umbilical cord is tied off or clamped, so the baby will have its first breath using lungs to exchange gas.

A lot of babies have gone through this without needing help or intervention, but some babies might need this. Neonatal resuscitation will help with breathing, establishing airflow, and also circulation. The first few moments of a baby’s life are the most important.

Effective emergency care during this transition might be needed to prevent lifelong consequences. A person who will do the neonatal resuscitation requires a good amount of knowledge and protocols, also essential pieces of equipment, before starting the procedure. If the baby is identified as needing neonatal resuscitation before birth, then first additional help is needed.

You are the shift leader at a fast food restaurant .Two employees named Tonya and Johnny get in a fight.Tonya left out a bunch of food ,but Johnny got blamed and had \$15 taken off his paycheck.Now he wants Tonya to pay him back ,but she is refusing .You call them both into the back room to have a conversation

I would say that I think it would be needed to investigate the facts to determine if it is true that Tonya left out the food that spoiled and not Johnny and if there were any extenuating circumstances and to determine that Johnny had no blame in the incident. If it is determined that Johnny had no blame, then the \$15 should be returned to Johnny by the restaurant and then \$15 taken from Tonya’s pay to correct the situation, keeping in mind that the whole purpose of the pay docking is only to ensure that food is not allowed to spoil.

His was the moment Zachary had been waiting for. He had rehearsed his lines for weeks, silently in his head as he biked to school, out loud in the mirror when he was home alone, and, to get used to an audience, in front of his sister’s stuffed animals and a slightly confused dog. Zachary had not prepared well for last year’s audition, and at the last minute had chosen not to go—too embarrassed—or too scared—he did not know which. Now, as he stood backstage, he thought about last year. He had been so disappointed in himself as he walked home alone, snuck to his room, and flopped sadly into his bed. “Next year will be different,” he vowed then and there. “I will be better prepared.” And he was. He just hoped it was enough. His throat was dry, his palms were sweaty, his heart was pounding, but he was ready to face the spotlight. A hushed silence fell across the auditorium as the drama teacher called his name. Zachary Hamilton. Based on the passage, how do you think Zachary will deal with the conflict in the remainder of the story?

The literary elements suggest that Zachary learned from last year and will have more success this time.

Explanation:

Larry wants to buy some carpeting for his living room. The length of the room is 3 times the width and the total area of the room is 27 square meters.

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

Since, distance between A and B is 10 units, so

d = 10.

Therefore,

Thus, the correct statement is

10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.

Option (C) is correct.

Here are a few pointers; hope this is useful)

Ovation-by definition- is show of appreciation from an audience, for a person’s accomplishments or flaw.

“Everyone deserves a standing ovation because we all overcometh the world.”

A person’s accomplishment could be how they made a positive change in this world, strong leadership- that makes them a effective leader or simply helping others. A person’s flaw- mistakes in life, sin or even guilt should also be considered an appreciation- an ovation for representing mankind’s flaw and that humanity makes mistakes, fulfilling at least one deadly sin such as greed, lust, selfishness etc.

Thus, regardless of a person’s achievement or flaw- a person deserves an applause for, not the least, living in this society and this world that we are all living together and dying together.

That was just the introduction.. the best part is yet to come.. now it’s your turn!!

Shakespeare’s famous line “All the World’s a stage. That agrees with your line: “Everybody deserves a standing ovation…”

Shakespeare explains that men and women are like players: they live, and die, some being celebrated and some forever living in solitude till their death. Shakespeare states the world is a “stage” which symbolizes that mankind is in its peak. The world is changing everyday: little by little and humanity is falling behind.
Due to our world turning into machinery: factories, an automotive future: where humans only job to live (entrance) and to die (exit) the famous humans remembered and the flawed not recalled.

This is according to Shakespeare’s imagery.

I don’t know what grade your in, but I think simplifying Shakespeare’s word of mouth in your essay would be handy and useful as it has strong references of your quote, and agrees strongly in your essay.

Hope this helps 🙂

The speed of sound at 0°C is 331.5 m/s. Calculate the speed of sound in the room at 20.0°C.

a) The time the police officer required to reach the motorist was 15 s.

b) The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) The total distance traveled by the officer was 225 m.

Explanation:

The equations for the position and velocity of an object moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position at time t

x0 = initial position

v0 = initial velocity

t = time

a = acceleration

v = velocity at time t

a)When the officer reaches the motorist, the position of the motorist is the same as the position of the officer:

x motorist = x officer

Using the equation for the position:

x motirist = x0 + v · t (since a = 0).

x officer = x0 + v0 · t + 1/2 · a · t²

Let´s place our frame of reference at the point where the officer starts following the motorist so that x0 = 0 for both:

x motorist = x officer

x0 + v · t = x0 + v0 · t + 1/2 · a · t²      (the officer starts form rest, then, v0 = 0)

v · t = 1/2 · a · t²

Solving for t:

2 v/a = t

t = 2 · 15.0 m/s/ 2.00 m/s² = 15 s

The time the police officer required to reach the motorist was 15 s.

b) Now, we can calculate the speed of the officer using the time calculated in a) and the  equation for velocity:

v = v0 + a · t

v = 0 m/s + 2.00 m/s² · 15 s

v = 30 m/s

The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) Using the equation for the position, we can find the traveled distance in 15 s:

x = x0 + v0 · t + 1/2 · a · t²

x = 1/2 · 2.00 m/s² · (15s)² = 225 m

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

This problem is to apply Roult’s Law.

Roult’s Law states that the vapor pressure, p, of a solution of a non-volatile solute is equal to the vapor pressure of the pure solvent, Po solv, times the mole fraction of the solvent, Xsolv

p = Xsolv * Po sol

X solv = number of moles of solvent / number of moles of solution

The solvent is water and the solute (not volatile) is glycerin.

Number of moles = mass in grams / molar mass

mass of water = 132 ml * 1 g/ml = 132 g

molar mass of water = 18 g/mol

=> number of moles of water = 132 g / 18 g/mol = 7.33333 mol

mass of glycerin = 27.2 g

molar mass of glycerin:, C3H8O3: 3 * 12 g/mol + 8 * 1 g/mol + 3*16 g/mol = 92 g/mol

number of moles of glycerin = 27.2g / 92 g/mol = 0.29565

total number of moles = 7.33333 moles + 0.29565 moles = 7.62898 moles

=> X solv = 7.33333 / 7.62898 = 0.96125

=> p = 0.96125 * 31.8 torr ≈ 30.57 torr ≈ 30.6 torr.

Which is a characteristic of unsaturated fats? they easily stack on top of each other. they come from plant steroids. they make up most animal fats. they are liquids at room temperature?

In tropical rain forest, the animals will have to deal with higher temperatures and greater rainfall. One example of an adaptation they might need is a thin, water-proof coat. This will prevent heat from becoming trapped inside their fur/hair/feathers, and the water-absorbing coating will allow water to stick to the inside of the coat without being absorbed, where the water will absorb the heat instead of themselves, and will cool the through evaporative cooling (heat release through evaporation)

In a deciduous forest, there is much colder temperatures, and significantly less rainfall. These animals would likely want a thicker water-proof coat. This is because the thicker coat would allow heat to become trapped, keeping them warm in the winter, and the water-proof coating prevents water from freezing in their fur, making them colder.

There are primarily three subatomic particles in an atom;
Protons
Electrons
Neutrons
—————-
Protons are positively charged subatomic particles in an atom. These particles give an element it’s identity, based on it’s ‘Atomic Number’, or how many protons are contained in the atom.

Electrons are negatively charged subatomic particles in an atom. These particles give an element it’s reactivity, and are a major part in finding where an element lies on the Periodic Table by valence electrons. We can discuss more of this in PM if you’d like to know more about this. Electrons are also a major part of finding an element’s ‘atomic mass’, or how many neutrons it has.

Neutrons are subatomic particles in an atom that have a neutral or ‘no’ charge. These are inside of the nucleus of an atom, as opposed to protons and electrons, which are farther outward of the center of an atom.

There are two systems in the human body that are responsible for the coordination between the functions of different systems to achieve the unity of the living organism’s body. These two systems are the nervous system and the endocrine system. The action of the nervous system is fast and takes a short time, while the action of the endocrine system is slow and takes a long time.

The functional unit of the nervous system is the nerve cell or the neuron. The neuron consists of a cell body and the axon. The cell body starts with the dendrites that receive the messages or the impulses from other neurons or from different sense organs or receptors. These impulses are then transmitted through the cell body. The cell body contains a nucleus and different organelles which help the nerve cell to perform its functions. The nerve impulse is then transmitted to the axon.

The axon is an extension from the cell body. There are some cells called Schwan cells that secrete a myelin sheath to insulate the axon from the surrounding medium. The insulated axons have more ability to conduct the impulses than non-insulated axons. The axon ends with the terminal arborizations. The terminal arborizations of a nerve cell connect to the dendrites of the next cell or to the afferent organ. The gaps between the dendrites and the terminal arborizations are called the synapses.

The nerve impulse is an electrochemical phenomenon i.e. an electrical phenomenon with a chemical nature. The membrane of the axon acts as a barrier between an outside positively charged medium and an inside negatively charged medium. This makes a potential difference of  -70mV. This state is called the resting potential. When the membrane is subjected to a stimulus, the positive charges enter to inside and the negative charges exit to the outside. The potential difference now becomes +40mV. This state is called the depolarization state. The point of stimulation acts as a new stimulus for the next point and so on. The membrane sooner gains its permeability again and the positive charges return to the outside and the negative charges to inside. This state is called repolarization.

The nerve impulse reaches the synapse. There are some neurotransmitters that are excited by the nerve impulse coming and carry the message across the membrane. Some receptors receive theses neurotransmitters on the dendrites of the next neuron. These receptors act as a stimulus for the new cell.

Hello! Okay let me start off by explaining to how you can simplify a square root…

Let’s take √12 for instance…

the factors of this number are 2, 3, 4, and 6 …. and out of these 4 numbers there is one perfect square, which is 4

so you can split √12 into —> √4 and √3  ….. these would then simplify into 2√3
because the 4 is square rooted

now by doing the same to √18 we get —-> √9 * √2 —->  3√2

Before we multiply the square roots we must remember that numbers underneath the square root can only be multiplied with other numbers underneath a square root….
so…

2√3 * 3√2
(2 * 3) * (√3 * √2)
