## A company is setting its direct materials and direct labor standards for its leading product. Direct material costs from the supplier areâ€‹ \$7 per squareâ€‹ foot, net of purchase discount.â€‹ Freight-in amounts toâ€‹ \$0.10 per square foot. Basic wages of the assembly line personnel areâ€‹ \$19 per hour. Payroll taxes are approximatelyâ€‹ 25% of wages. How much is the direct labor cost standard perâ€‹ hour

The formula for calculating the direct labor standard is:

Direct labor standard = Basic wages + Payroll tax

or

Direct labor standard = Basic wages + 25% of Basic wages

Substituting the given values into the equation:

Direct labor standard = \$19 + 0.25 * \$19

Direct labor standard = \$23.75

## Which statement is supported by information in the charts? Select all that apply. 1. The share of world GDP contributed by the United States declined between 2000 and 2010. 2. The share of world GDP contributed by China increased between 2000 and 2010. 3. US GDP declined from 2000 to 2010. 4. World GDP declined from 2000 to 2010. 5. The amount contributed by nations other than China and the United States increased from 2000 to 2010.The graphs show the percentages, not the actual amounts.

Noninvolvement in world affairs is termed “isolationism”.

Explanation:

Isolationism is a concept that designates a political inclination that defends the isolation and nonintervention of a country in international conjunctural issues. That is, putting it in simpler terms, isolationism proposes that a country does not intervene in any way in an external conflict that afflicts another nation or group of nations so that it does not end up affecting their interests.

Basically, isolationism causes that the country that adopts this position is totally isolated from everything that happens in the rest of the world so that nothing affects it in its possible benefits.

## Marie has \$830 in her bank account and withdraws \$60 each month. Denise has \$970 in her bank account and withdraws \$80 each month. In how many months will Marie and Denise have equal amounts of money in their accounts? A. 4 B. 5 C. 7 D. 9

The basis to respond this question are:

1) Perpedicular lines form a 90° angle between them.

2) The product of the slopes of two any perpendicular lines is – 1.

So, from that basic knowledge you can analyze each option:

a.Lines s and t have slopes that are opposite reciprocals.

TRUE. Tha comes the number 2 basic condition for the perpendicular lines.

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

b.Lines s and t have the same slope.

FALSE. We have already stated the the slopes are opposite reciprocals.

c.The product of the slopes of s and t is equal to -1

TRUE: that is one of the basic statements that you need to know and handle.

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

g.The intersection of s and t forms right angle.

TRUE: right angle = 90°.

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

So, the right choices are a, c and g.

## How are amounts of hydrogen and oxygen gas made from the electrolytic decomposition of water related to the chemical formula of water?

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.

## Choose one of the distribution methods. Write 1-2 paragraphs of 100-200 words that explains the distribution method that you have chosen. In your response, be sure to answer the following questions: Who receives the good or service from this distribution method? Who does not receive the good or service? What are the advantages of this method? What are the disadvantages of this method? Is this method efficient (or not wasting resources)? Is it fair (or free from bias)? Can your chosen method be used to distribute large amounts of goods and services to many people each day? Why or why not? please help me

Not sure if this is a “Select all that apply” question, because most of these could work. However, I’m going to assume the answer is easy movement on people, products, and ideas.Improve transportation has allowed better import and exports, faster transportation cross country, even around the world. At the same time, the answer could be increase greenhouse gases and increase pollution, because they release toxic fumes through exhaust. So, if it’s a Select all that apply question, i would select those three.

## Which best explains why fungi are often called natural recyclers? They provide a continuous food resource for many other organisms. They break down rotting materials and return nutrients to the soil. They take in large amounts of carbon dioxide, helping to clean the air. They are found in nature and have many different practical uses.

The human activities that lead to soil erosion are deforestation and agriculture.

Explanation:

Soil erosion (the wearing away and displacement of the topsoil) may be caused by natural factors such as strong winds, water, ice and animals, or by human activities that make the soil weak.

Deforestation is the logging or burning of trees for the purpose of construction or the usage of wood for several activities (heating or paper-making). When they remove the vegetation, they leave the upper layer of soil (topsoil) unprotected against winds and water.

Agriculture is the activity of growing crops for the production of food. When farmers plant their vegetation, they remove the topsoil and this is mostly carried away by winds into water streams (they become sediments).

## Maria is concerned because she has been exposed to a small amount of radiation during an X-ray. What is her doctor most likely to tell her? Radiation from X-rays is not a mutagen unless you have X-rays every day. Mutagens have no effect on the body unless you have inherited them. Small amounts of a mutagen often do not have an effect on health. Severe mutations are usually caused by small amounts of a mutagen.

Let us systematically break our problem into hypothesis, testable version of hypothesis, constant, and variables.

Hypothesis: In the experiment, you will determine whether having worms in the soil affects the growth of lima bean plants.

Variables: Independent variable – presence of worms, dependent variable – amount of growth in lima bean plants (measured as the change in length of the plant shoot)

Constant: Amount of soil, amount of water given to the plant.

Our question would be a testable version of the hypothesis.

Testable hypothesis:

1. Presence of worms in soil will promote growth of lima bean plants.

2. Presence of worms in soil will stop the growth of lima bean plants.

Null hypothesis: Presence of worms in soil will not affect the growth of lima bean plants.

While trying to answer the question our goal will be to first reject the null hypothesis by gathering evidence through experimental observation. Then, we will test the parts 1 and 2 of the testable hypothesis.

Statement A is correct about Sam’s box and whisker plot.

Step-by-step explanation:

We have been given a box plot and we are asked to find out true statement according to the box plot.

Since we know data represented by box plot is divided in four equal parts.

Upon looking at our box plot we can see that our data is symmetric. It’s median is 15, which means half the math assignments have less than 15 problems and half of the math assignments have more than 15 problems.

Interquartile range represents 50% values of data and it is the difference between upper quartile and lower quartile. IQR is not affected by outliers.

Upon substituting given values from box plot we get,

From IQR we can conclude that half of the assignments contained 15 problems or fewer.Therefore, option A is the correct choice.

When a child is little, they must have a ton of interaction with other people. Children repeat things they hear when they’re little, and with the caregiver not communicating with the child, they don’t have a chance to engage the brain through words. With the caretaker not using the child’s name, the babe might not respond when people call their name, which is not good. With no walking or crawling, the baby will have a hard time learning as it isn’t practicing when it counts the most.

The standard deviation σ is the square root of the variance:σ=V(X)−−−−−√=E(X2)−(E(X)2−−−−−−−−−−−−−√)where E(X)is the expected value of X. By definition,E(X)=∑x∈Dxp(x)where D is the values X may take (in this case D={0,1,2,3,4,5})and p(x)=P(X=x)is the probability that X equals x.Then,E(X)==0⋅p(0)+1⋅p(1)+2⋅p(2)+3⋅p(3)+4⋅p(4)+5⋅p(5)2.15.
Similarly,E(X2)==02⋅p(0)+12⋅p(1)+22⋅p(2)+32⋅p(3)+42⋅p(4)+52⋅p(5)6.75,soV(X)=6.75−2.15=4.6andσ=4.6−−−√≈2.144.

a golf ball travels a distance of 600 feet as measured along the ground and reaches an altitude of 200 feet. If the origin represents the tee and the ball travels along a parabolic path that opens downward, find an equation for the path of the golf ball. …?

y=1.32x-0.0022

Step-by-step explanation:

Let the standard equation of parabola be y=a+bx+c ……. (1)

Let y be the altitude of the ball and x be the distance traveled by the ball.

Now by putting the points one by one, we get the required equation.

first point = (0,0)

golf ball travels a distance of 600 feet  along the ground. Therefore point = (600,0)

At altitude of 200, it travels the distance of 300 feet(mid point) = (300,200)

By putting y=0 and x=0 in (1),

we get c=0,

By putting y=0 and x=600 we get

0 = 360000a+600b …………..(2)

By putting y=200 and x=300, we get

200=90000a+300b …………….(3)

Solving (2) and(3) we get, a=-0.0022 and b = 1.32

So the required equation is :

y= =0.0022+1.32x
