## Sam wants to buy 8 pencils and 6 pens, which cost a total of $8.50. He realizes he doesn’t have enough cash and instead takes only 4 of each, which costs only$5. What is the price of each pen and pencil? pen, $0.75; pencil,$0.50

X = pencils, y = pens

8x + 6y = 8.50
4x + 4y = 5…..multiply by -2
—————-
8x + 6y = 8.50
-8x – 8y = -10 (result of multiplying by -2)
-2y = – 1.50
y = -1.50 / -2
y = 0.75 <=== pens cost 0.75

4x + 4y = 5
4x + 4(0.75) = 5
4x + 3 = 5
4x = 5 – 3
4x = 2
x = 2/4
x = 0.50 <== pencils cost 0.50

## Read the passage. (1) Most Americans know that “Uncle Sam” is a nickname for the United States; however, few Americans know how the name originated. (2) Some historians believe the name comes from a nineteenth-century businessman from New York. (3) His real name was Samuel Wilson. (4) His neighbors called him Uncle Sam. (5) During the War of 1812, he won a government contract. (6) He was to supply beef to U.S. soldiers. (7) The beef was packed in barrels labeled “U.S.” to show that they belonged to the U.S. government. (8) Soldiers from New York saw the barrels. (9) They jokingly said “U.S.” stood for Uncle Sam. (10) The joke spread. (11) Soon, soldiers began using the nickname Uncle Sam to refer to the United States. (12) Civilians also began using the nickname Uncle Sam to refer to the United States. (13) In 1961, Congress passed a resolution. (14) The resolution recognized Samuel Wilson as the original Uncle Sam. Which is the most effective way to combine sentences (5) and (6)? During the War of 1812, he won a government contract he was to supply beef to U.S. soldiers. During the War of 1812, to supply beef to U.S. soldiers was what he won a government contract for. During the War of 1812, he won a government contract to supply beef to U.S. soldiers.

During the War of 1812, he won a government contract to supply beef to U.S. soldiers.

Explanation:

One of the uses of the preposition “to” is to work as an infinitive of purpose, this makes a focus on the objective or purpose of a sentence in the next sentence. So in the first part of the sentece, we have a statement of the situation(he won a contract), in the second part we have the purpose (of the contract) merged by “to” (with the purpose of):.

## Ron is half as old as Sam, who is three times as old as Ted. The sum of their ages is 55. How old is Ron?

Ahemmm having x-intercepts of -3 and -5.. ..well, that simply means, -3 and -5 are roots or solutions or zeros of the equation

it namely means x = -3 and x = -5, an x-intercept is when the graph touches the x-axis, at that point, the y-intercept is 0, so the point is (-3, 0) and (-5, 0)

if the roots are -3, and -5, then

if you have the zeros/x-intercepts/solutions of the polynomial, all you have to do is, get the factors, as above, and get their product, to get the parent original polynomial.

## The cartoon below titled “Where the Blame Lies” was created in the late 1800s: A political cartoon shows Uncle Sam standing on a platform. A man stands next to Uncle Sam and points out to a crowd of people. They appear to be entering the United States after exiting ships in New York Harbor. The people seem to be walking in a wild manner. The Statue of Liberty and the American flag can be seen in the background. © The Granger Collection/Image Quest 2012 Which political issue does this cartoon illustrate? the effects of unchecked immigration the health effects of the factory system the effects of low American wages the effects of prohibiting alcohol on society

The correct answer is A) the effects of unchecked immigration.

The political that this cartoon illustrates is the effects of unchecked immigration.

The cartoon describes a situation of immigrants. So, it illustrates the effects of unchecked immigration with so many people entering the United States with no order at all. The situation shows the risk of a lack of immigration policy could have on the country and the possible consequnences of such a few restrictions to enter the U.S.

The sign that says “Baggage the only Requisite”, showed how easy was for people to enter the United States. And the pice of paper on the floor, besides Uncle Sam, with the names of “Mafia in New Orleans”, “Anarchist in Chicago”, and “Socialist in New York”, is an example of the strong journalism critic of that time.

## Josh kept 75% of the ride tickets he bought at a carnival and gave the rest to his friend Sam. Sam gave 50% of these tickets to Rob. If Rob was given 3 tickets, how many tickets did Josh buy?

Solution:

The Given Rectangle having dimensions

Length = 80 cm

Let the Six squares which has been cut from this rectangle have side of length a cm.

Area of each square = (Side)²= a²

Area of 6 Identical Squares = 6 × a²= 6 a²

If four squares are cut from four corners and two along Length,

then , Length of Box = (80 – 3 a)cm, Breadth of Box = (50 – 2 a)cm, Height = a cm

Volume of Box =V = Length × Breadth × Height

V = (80 – 3 a)× (50 – 2 a)× a

V   = 4000 a – 310 a² + 6 a³

For Maximum Volume

V’= 0 , where V’ = Derivative of V with respect to a.

V’= 4000 – 620 a + 18 a²

V’ =0

18 a² – 620 a + 4000= 0

9 a² – 310 a + 2000=0

using determinant method

cm

V”=1 8 a – 310 = -ve

which shows , when a = 8.6 cm , volume is maximum.

So, V = 4000×8.6 – 310×(8.6)²+6×(8.6)³=15288.736 cm³

OR

If four squares are cut from four corners and two along Breadth,

then , Length of Box = (80 – 2 a)cm, Breadth of Box = (50 –  3 a)cm, Height = a cm

Volume of Box =V = Length × Breadth × Height

V = (80 – 2 a)× (50 – 3 a)× a

V   = 4000 a – 340 a² + 6 a³

For Maximum Volume

V’= 0 , where V’ = Derivative of V with respect to a.

V’= 4000 – 680 a + 18 a²

V’ =0

18 a² – 680 a + 4000= 0

9 a² – 340 a + 2000=0

Using Determinant method

cm

V”=18 a -340= -ve value when a = 7.6 cm, shows volume is maximum when a = 7.6 cm

V= 4000×7.6 -340 × (7.6)² +6× (7.6)³=13395.456 cubic cm

## The number of hours walked varies inversely with the speed of the walker. if it takes sam 12 hours to complete his walking goal at 5 miles per hour, how long would it take him at 3 miles per hour?

Option C – BD=76 cm

Step-by-step explanation:

Given : You are designing a diamond-shaped kite. you know that AD = 44.8 cm, DC = 72 cm, and AC = 84.8 cm.

To find : How long BD should it be?

Solution :

First we draw a rough diagram.

The given sides were AD = 44.8 cm, DC = 72 cm and AC = 84.8 cm.

According to properties of kite

Two disjoint pairs of consecutive sides are congruent.

DC=BC=72 cm

The diagonals are perpendicular.

So, AC ⊥ BD

Let O be the point where diagonal intersect let let the partition be x and y.

AC= AO+OC

AC=   …….[1]

Perpendicular bisect the diagonal BD into equal parts let it be z.

BD=BO+OD

BD=z+z

Applying Pythagorean theorem in ΔAOD

where H=AD=44.8 ,P= AO=x , B=OD=z

………[2]

Applying Pythagorean theorem in ΔCOD

where H=DC=72 ,P= OC=y , B=OD=z

…………[3]

Subtract [2] and [3]

……….[4]

Add equation [1] and [4], to get values of x and y

Substitute x in [1]

Substitute value of x in equation [2], to get z

We know, BD=z+z

BD= 38.06+38.06

BD= 76.12

Nearest to whole number BD=76 cm

Therefore, Option c – BD=76 cm 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 🙂

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in “consensus democracy” in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

## Sam and Edna have 56 marbles together Edna has 6 times more marbles than Sam. How many marbles does sam have ?

Well first you have to make variables for each number.
1st – x
2nd – y
3rd – z

first sentence says twice first number so 2x. is means equals so =. eleven more than sum of the other two numbers. sum of other two numbers is (y + z) and eleven more than that is (y + z) + 11. So so this sentence says:
2x = (y + z) + 11

second sentence says sum of twice the first and three times third. twice first is 2x and three times third is 3z. their sum would be (2x + 3z). It it says is one more than second number. So = (y + 1). So so this means:
(2x + 3z) = (y + 1)

third sentence says second number (y) is is equal to sum of first and third (x + z). so;
y = (x + z)

now for the work.

We we can easily solve for a by subtracting the first 2 equations. the way to subtract 2 equations is by subtracting one left side of equal sign from the other equations left side and then doing the same with the right side.

So we will subtract the 1st and second equations we made.
So so left sides would be
2x – (2x + 3z)
2x – 2x – 3z
-3z

right side would be:
y + z + 11 – (y + 1)
y + z + 11 – y – 1
z + 10

now put the sides with an equal sign
-3z = z + 10
-4z = 10
z = -2.5

now we can plug in z into the equations and subtract second and third equations. But but we will subtract opposite sides. So so left minus right and right mi is left after we plug in z:
(2x + 3 (-2.5)) – (x + (-2.5))
2x – 7.5 – x + 2.5
x – 5

other one would be
(y + 1) – y
1

So so put an equal sign and get:
x – 5 = 1
x = 6

now plug x and x into 3rd equation
y = x + z
y = 6 + (-2.5)
y = 3.5

now we have values. You can check answer by plugging values into other 2 equations

C. If we were left solely to the wordy wit of legislators in Congress for our guidance, uncorrected by the seasonable experience and the effectual complaints of the people, America would not long retain her rank among the nations.

D. Even the Chinese philosopher was wise enough to regard the individual as the basis of the empire.

E. There will never be a really free and enlightened State until the State comes to recognize the individual as a higher and independent power, from which all its own power and authority are derived, and treats him accordingly.

David Thoreau’s “The Civil Disobedience” emphasizes the need to prioritize the conscience of individuals over what laws dictate them to do. He defends and tries to encourage citizens to institute a better government, a government that respects individuals. To do so, Thoreau defends that the government is formed by the people and for the people, this way, when a government abuses its powers people have the right to regain power.

Thoreau refused to submit himself to regulations and taxes that were imposed by the government, he believed that they were unfair to him and all Americans.
