Answer:
Demand for recycled paper has increased as consumers have become more aware of the environmental issues surrounding waste disposal. Paper is a natural raw material made from renewable wood and plants. Recycled paper is made from waste paper and paperboard. Both new paper and recycled paper contain traces of heavy metals. However, some types of recycled paper contain more heavy metals than new paper due, in part, to the inks used for printing or adding color to the original paper. Metals can migrate from the paper packaging and containers used for food to the food itself. This metal migration is controlled and monitored to reduce the exposure of humans to heavy metals. Food agencies in each country determine the limit of cadmium, zinc, nickel, and copper in packaging materials. Most countries impose a limit of heavy metals in recycled paper not to exceed 100.0 ppm or 100.0 . The limit for lead in eggfruit, or vegetable-packaging is lower-not to exceed-20.0 mg/kg. The table in Figure a lists the results of the analysis of samples of recycled paper produced by a manufacturer during a three-month period. The goal of the manufacturer is to reduce the amount of heavy metals-especially lead-in the recycled paper it produces and sells. From March to May, the manufacturer varied the
methods of production each month to determine which method would produce paper with the lowest metal content. Each month, lab technicians cut small samples of recycled paper with an area of 1.000 and a thickness of 0.0500 The technicians then prepared the samples for analysis. The average density of the samples is Use the information provided in the figure to answer the
following questions:
a. Did the company reduce the amount of lead in its product between March and May?
b. Which metal was not reduced?
c. Each month's sample represents a different manufacturing process. Which process would you recommend the manufacturer choose to continue to use over the next year while additional processes are tested? Why?
d. What is the total amount of the five metals for the April sample (in mg/kg)?
e. What is the total mass (in mg) of the five metals for the April sample found in the 1.000 sample?
f. Lead has four stable isotopes: 204
Explanation:
so this problem gives us a lot of information and asked us to answer several questions. So, Letter A says, did the company make reduce the amount of lead in its product between March and May? And the answer is yes. The PB levels went from 3.5 to 2.8 22.4, so it was reduced. Be asks which medal was not reduced. And that would be sync because England from 2.723 point 2.723 2 to 3.7 so zinc increased. It was not reduced. See says each month sample represents a different manufacturing process.

Explanation:
Harriet Ann Jacobs's autobiographical narrative "Incidents in the Life of a Slave Girl" delves into the discriminatory system of slavery and how it affects the blacks, especially the women slaves. This autobiography deals with the issue of slavery and the need for everyone to try to refrain from practicing it. The book also contains her journey and efforts to try to get her freedom from being a slave.
The bolded words in each of the quotes can be closely matched accordingly-
1.<u> Evinced means to show</u>. Considering the sentence or quote, we can infer that the author has so much intelligence that led to her masters to keep her.
2. <u>Forebore here means refused or concealed or refrain from mentioning</u>. This quote means that when Uncle Philip came with the good news, he told mother everything except some of the details about Benjamin, <em>"her darling"</em> so as not to hurt her.
3. The word<em> </em><u><em>"eking"</em></u><u> </u><u>signifies an effort or act to make a supply last economically</u>. This is evident when Harriet narrates how her mistress Mrs. Flint used to observe carefully how the provisions of the household were used. She mentions that she (Mrs. Flint) makes sure the slaves do not use up their provisions just to make themselves full. This shows a mean-spirited nature in most mistresses at those times.
4.<u> Disencumber most closely signifies one's desire to be free from or released from something or someone</u>. According to the quote, Harriet expressed her despise for her master who told her that <em>"[she] was made for his use, made to obey his command in everything"</em>. So, this is her expression of wanting her master gets swallowed up by the earth.
11. ADV (<em>Although many tornadoes occur throughout the United States </em>is an adverbial subordinate clause because it functions as an adverb expressing concession.)
12. ADJ (This sentence contains two adjectival clauses coordinated with one another with the conjunction <em>or</em>.)
13. N (<em>that trucks can no longer travel on Grove Street</em> is a noun subordinate clause because it functions as a noun in this sentence and it is the object of the verb <em>heard</em>.)
14. ADV (<em>before you put it in the freezer</em> is an adverbial subordinate clause, because it functions as an adverb, which expresses time.)
15. ADV (<em>Since I will have a test in Spanish</em> is an adverbial subordinate clause because it functions as an adverb expressing reason.)
