A metalworker has a metal alloy that is 25% copper and another alloy that is 60% copper.How many kilograms of each alloy should the metalworker combine to create 50kg of a 46% copper alloy

Answers

Answer:

20kg of 25% copper alloy

30kg of 60% copper alloy

Step-by-step explanation:

There are 2 kinds of metal, first metal(A) have 25% copper while the second metal(B) has 60% copper. The metalworker want to create 50kg of metal, which means the total weight of both metals is 50kg (A+B = 50). The metalworker also want the metal made of a 46% which is 23kg(0.25A + 0.6B = 0.46*50). From these sentences, we can derive 2 equations. We can solve this with substitution.

A+B = 50

A= 50-B

Let's put the first equation into the second.

0.25A + 0.6B = 0.46 *50

0.25(50-B) + 0.6B =23

12.5 - 0.25B + 0.6B =23

0.35B=23 -12.5

B= 10.5/ 0.35= 30

Then we can solve A

A= 50-B

A= 50-30

A=20

Julia finds that the data in the table can be modeled by the function y = 5(4)x. A 2-column table with 5 rows. The first column is labeled time (minutes) with entries 0, 1, 2, 4, 8. The second column is labeled distance (feet) with entries 5, 20, 80, 320, 640.
Which statement about Julia’s finding is true?

Julia is correct because the distance starts at 5 feet and increases by a factor of 4.
Julia is correct because the function is true for (0, 5) and (1, 20).
Julia is not correct because the function is not true for the point (2, 80).
Julia is not correct because the distance does not increase by a constant factor each minute.

Answers

Answer:

Julia is not correct because the distance does not increase by a constant factor each minute.

Step-by-step explanation:

Julia modeled the data in the table by the function .

A 2-column table with 5 rows. The first column is labeled time (minutes) with entries 0, 1, 2, 4, 8. The second column is labeled distance (feet) with entries 5, 20, 80, 320, 640.

The values of y corresponding to the values of x are correct up to x = 2.

Now, for x = 4, the value of y is 1280 ≠ 320 and for x = 8, the value of y will be 327680 ≠ 640

Therefore, Julia is not correct because the distance does not increase by a constant factor each minute. (Answer)

1 I am happy to join with you today in what will go down in history as the greatest demonstration for freedom in the history of our nation. 2 Five score years ago, a great American, in whose symbolic shadow we stand today, signed the Emancipation Proclamation. This momentous decree came as a great beacon light of hope to millions of Negro slaves who had been seared in the flames of withering injustice. It came as a joyous daybreak to end the long night of their captivity. 3 But one hundred years later, the Negro still is not free. One hundred years later, the life of the Negro is still sadly crippled by the manacles of segregation and the chains of discrimination. One hundred years later, the Negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. One hundred years later, the Negro is still languishing in the corners of American society and finds himself an exile in his own land. So we have come here today to dramatize a shameful condition. 4 In a sense we have come to our nation's capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. This note was a promise that all men, yes, black men as well as white men, would be guaranteed the unalienable rights of life, liberty, and the pursuit of happiness. 5It is obvious today that America has defaulted on this promissory note insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check, a check which has come back marked "insufficient funds." But we refuse to believe that the bank of justice is bankrupt. We refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation. So we have come to cash this check — a check that will give us upon demand the riches of freedom and the security of justice. We have also come to this hallowed spot to remind America of the fierce urgency of now. This is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. Now is the time to make real the promises of democracy. Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. Now is the time to lift our nation from the quick sands of racial injustice to the solid rock of brotherhood. Now is the time to make justice a reality for all of God's children. Read the passage above to answer the following questions: 5) When Dr. King said, "We have come to our nation's capital to cash a check," he was using A) hyperbole. B) personification. C) an extended simile. D) an extended metaphor. 6) Which statement BEST explains seared in the flames of withering injustice as it is used in the second paragraph? A) Injustice began fading away for slaves. B) Slaves were not haunted by the pain of injustice. C) Slaves had been tortured and scarred by injustice. D) Slaves were not bothered by the injustice served to them. 7) Which sentence uses a simile to dramatize Dr. King's point vividly? A) But one hundred years later, the Negro still is not free. B) So we have come here today to dramatize a shameful condition. C) We have also come to this hallowed spot to remind America of the fierce urgency of now. D) This momentous decree came as a great beacon light of hope to millions of Negro slaves who had been seared in the flames of withering injustice. 8) When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. What is the root word of promissory as it is used in this sentence? A) miss B) missory C) prom D) promise

Determine the type of plagiarism by clicking the appropriate radio button.Original SourceAnalysis of patterns in time (APT) is a method for gathering information about observable phenomena such that probabilities of temporal patterns of events can be estimated empirically. If appropriate sampling strategies are employed, temporal patterns can be predicted from APT results. Finally, APT is compared to the linear models approach and event history analysis. The major difference is that in APT there is no mathematical model assumed to characterize relations among variables. In APT the model is the temporal pattern being investigated.References:Frick, T. (1990). Analysis of Patterns in Time (APT): A Method of Recording and Quantifying Temporal Relations in Education. American Educational Research Journal, 27(1), 180-204.Student VersionAPT is an empirical approach to observing and coding phenomena by using mutually exclusive and exhaustive categories within multiple classifications (Frick, 1990). Once these data have been collected, researchers specify APT queries to calculate the probability of joint and/or sequential patterns of interest. In effect, researchers create measures of temporal patterns by counting the occurrences of these coded patterns. According to Frick, Analysis of Patterns in Time is different from the linear models approach of measuring variables separately and using statistics to analyze their relations.References:Frick, T. (1990). Analysis of Patterns in Time (APT): A Method of Recording and Quantifying Temporal Relations in Education.
