Answers

ANSWER: 4/21 teaspoons of salt


2 1/3 flour : 1/3 salt

2 1/3 cups of flour = 7/3
To get 2 cup of flour we need 3/3 so we take away 4/3 of the flour

7/3 ÷ 4/3 = 1.75
so we ÷ both by 1.75 to get the same ratio

1/3 teaspoons ÷ 1.75 = 4/21 teaspoons of salt

Answers

Answer:

Step-by-step explanation: bc i said

The possible error of measurement is half of the smallest unit on the tape measure, which is half an inch, option B is correct.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The possible error of measurement refers to the smallest unit of measurement on the tape measure.

In this case, the tape measure is marked every half inch, so the smallest unit of measurement is 0.5 inches.

Therefore, the possible error of measurement is also 0.5 inches.

This means that any measurement taken using this tape measure may be off by up to 0.5 inches due to the limitations of the instrument used.

Hence, the possible error of measurement is half of the smallest unit on the tape measure, which is half an inch. Therefore, the answer is B. 0.5 in.

Monica paid sales tax of $2.40 when she bought a new bike helmet. If the sales tax rate was 6%, how much did the store charge for the bike helmet before tax?

Answers

Answer: $40

Step-by-step explanation:

The tax rate is 6% on the price of the good bought.

This means that $2.40 is 6% of the price of the helmet before taxes.

Assuming the before tax price is x, the price of the helmet is:

2.40 = x * 6%

x = 2.40 / 6%

x = $40

$40 is the before tax cost.

Element X decays radioactively with a half life of 6 minutes. If there are 390 grams of
Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 28 grams?
y =
= a(.5)^ t/h

Answers

Answer:

The time it would take the element to decay to 28 grams is approximately 22.5 minutes

Step-by-step explanation:

The give half life of element X = 6 minutes

The given initial mass of the radioactive element X = 390 grams

The mass of the element X after decay = 28 grams

The function that represent the decay of element X is given as follows here;

[tex]y = a \cdot (0.5)^{\dfrac{t}{h} }[/tex]

Which is of the form;

[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]

Therefore;

h = 6 minutes = The time duration of the half life

a = N₀ = The initial mass = 390 g

N(t) = The final mass = 28 g

t = The time it takes the element to decay

Plugging in the values gives;

[tex]28 = 390 \times(0.5)^{\dfrac{t}{6} }[/tex]

[tex](0.5)^{\dfrac{t}{6} } = \dfrac{28}{390}[/tex]

Therefore;

[tex]\dfrac{t}{6} \times ln\left(0.5} \right) = ln \left(\dfrac{28}{390} \right)[/tex]

t/6 = ln(29/390)/ln(0.5)

t = 6 ×  ln(29/390)/ln(0.5) ≈ 22.496

Given the answer to the nearest tenth of a minute, the time it would take the element to decay to 28 grams, t ≈ 22.5 minutes.

The Civil War had been raging for years, and hundreds of thousands of Americans were dead. The war was nearly over, but President Lincoln would not see the country reunited. He was assassinated in April 1865.Fellow-Countrymen:At this second appearing to take the oath of the Presidential office there is less occasion for an extended address than there was at the first. Then a statement somewhat in detail of a course to be pursued seemed fitting and proper. Now, at the expiration of four years, during which public declarations have been constantly called forth on every point and phase of the great contest which still absorbs the attention and engrosses the energies of the nation, little that is new could be presented. The progress of our arms, upon which all else chiefly depends, is as well known to the public as to myself, and it is, I trust, reasonably satisfactory and encouraging to all. With high hope for the future, no prediction in regard to it is ventured.On the occasion corresponding to this four years ago all thoughts were anxiously directed to an impending civil war. All dreaded it, all sought to avert it. While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, insurgent agents were in the city seeking to destroy it without warseeking to dissolve the Union and divide effects by negotiation. Both parties deprecated war, but one of them would make war rather than let the nation survive, and the other would accept war rather than let it perish, and the war came.One-eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the southern part of it. These slaves constituted a peculiar and powerful interest. All knew that this interest was somehow the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union even by war, while the Government claimed no right to do more than to restrict the territorial enlargement of it. Neither party expected for the war the magnitude or the duration which it has already attained. Neither anticipated that the cause of the conflict might cease with or even before the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible and pray to the same God, and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces, but let us judge not, that we be not judged. The prayers of both could not be answered. That of neither has been answered fully. The Almighty has His own purposes. "Woe unto the world because of offenses; for it must needs be that offenses come, but woe to that man by whom the offense cometh." If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to Him? Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.How does Lincoln's use of the phrases "malice toward none," "charity for all," and "firmness in the right" affect Paragraph 4?A. They highlight the innovative nature of Lincoln's ideas.B. They demonstrate Lincoln's belief in retribution.C. They suggest that success and victory are guaranteed.D. They help convey the loftiness and virtue of his message.How do the impact identified in Part A and Lincoln's use of repetition at the beginning of Paragraph 4 advance his purpose?A. They encourage people to agree that the opposition brought the war on itself. B. They develop support for the idea of ending the war at all costs. C. They rally greater belief in the cause for which one side is fighting the war. D. They work to inspire unification in support of a moral resolution of the war.

He had the finest aviary in Europe, so large that eagles did not find it uncomfortable, so well laid out that both humming birds and snowbuntings had a climate that suited them perfectly. But for many years the finest set of apartments remained empty, with just a label saying: "PHOENIX. Habitat: Arabia." Many authorities on bird life had assured Lord Strawberry that the phoenix is a fabulous bird, or that the breed was long extinct. Lord Strawberry was unconvinced: his family had always believed in phoenixes. At intervals he received from his agents (together with statements of their expenses) birds which they declared were the phoenix but which turned out to be orioles, macaws, turkey buzzards dyed orange, etc., or stuffed cross-breeds, ingeniously assembled from various plumages. Finally Lord Strawberry went himself to Arabia, where, after some months, he found a phoenix, won its confidence, caught it, and brought it home in perfect condition.It was a remarkably fine phoenix, with a charming character affable to the other birds in the aviary and much attached to Lord Strawberry. On its arrival in England it made a greatest stir among ornithologists, journalists, poets, and milliners, and was constantly visited. But it was not puffed by these attentions, and when it was no longer in the news, and the visits fell off, it showed no pique or rancour. It ate well, and seemed perfectly contented. It costs a great deal of money to keep up an aviary. When Lord Strawberry died he died penniless. The aviary came on the market. In normal times the Rarer birds, and certainly the phoenix, would have been bid for by the trustees of Europes great zoological societies, or by private persons in the U.S.A.; but as it happened Lord Strawberry died just after a world war, when both money and bird-seed were hard to come by (indeed the cost of bird-seed was one of the things which had ruined Lord Strawberry). The London Times urged in a leader that the phoenix be bought for the London Zoo, saying that a nation of bird-lovers had a moral right to own such a rarity; and a fund, called the Strawberry Phoenix Fund, was opened. Students, naturalists, and school-children contributed according to their means; but their means were small, and there were no large donations. So Lord Strawberrys executors (who had the death duties to consider) closed with the higher offer of Mr. Tancred Poldero, owner and proprietor of Polderos Wizard Wonderworld. For quite a while Mr. Poldero considered his phoenix a bargain. It was a civil and obliging bird, and adapted itself readily to its new surroundings. It did not cost much to feed, it did not mind children; and though it had no tricks, Mr. Poldero supposed it would soon pick up some. The publicity of the Strawberry Phoenix Fund was now most helpful. Almost every contributor now saved up another half-crown in order to see the phoenix. Others, who had not contributed to the fund, even paid double to look at it on the five-shilling days. But then business slackened. The phoenix was as handsome as ever, and amiable; but, as Mr. Poldero said, it hadnt got Udge. Even at popular prices the phoenix was not really popular. It was too quiet, too classical. So people went instead to watch the antics of the baboons, or to admire the crocodile who had eaten the woman. One day Mr. Poldero said to his manager, Mr. Ramkin: "How long since any fool paid to look at the phoenix?" "Matter of three weeks," replied Mr. Ramkin. "Eating his head off," said Mr. Poldero. "Let alone the insurance. Seven shillings a week it costs me to insure the Archbishop of Canterbury." "The public dont like him. Hes too quiet for them, thats the trouble. Wont mate nor nothing. And Ive tried him with no end of pretty pollies, ospreys, and Cochin-Chinas, and the Lord knows what. But he wont look at them." "Wonder if we could swap him for a livelier one," said Mr. Poldero. "Impossible. Theres only one of him at a time." "Go on!" "I mean it. Havent you ever read what it says on the label?" They went to the phoenixs cage. It flapped its wings politely, but they paid no attention. -Kim What British demand led to the Opium Wars in China?

Just curious, I want to see who can get this. tooooootttalllllly know it alreadyAssume that we have two variables a and b, and that: a = bMultiply both sides by a to get: a2 = abSubtract b2 from both sides to get: a2 - b2 = ab - b2This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a - b) and factor out b from the right side to get b(a - b). If you're not sure how FOIL or factoring works, don't worryyou can check that this all works by multiplying everything out to see that it matches. The end result is that our equation has become: (a + b)(a - b) = b(a - b)Since (a - b) appears on both sides, we can cancel it to get: a + b = bSince a = b (that's the assumption we started with), we can substitute b in for a to get: b + b = bCombining the two terms on the left gives us: 2b = bSince b appears on both sides, we can divide through by b to get: 2 = 1 Which of these BEST explains why most of Canada's population has settled near its border with the United States?
