Answer:
3.1 ft/sec
Explanation:
we are talking about a right-angled triangle.
the Hypotenuse c is the line (rope) connecting the boat and the winch.
the side a is the height of the winch (8 ft straight up from the water level).
the side b is the distance of the boat to the dock on the surface of the water. 6ft.
c² = 8² + 6² = 100
c = 10 ft
when pulling in 1.5 ft of the rope, I create a new triangle, where side a is still the same, the new side c is 1.5 ft shorter than the original one, and we need to calculate the new side b based on that.
the difference of original b and new b is then the distance per second (= the rate) of the boat being pulled at that point.
so,
(10-1.5)² = 8² + b²
8.5² = 64 + b²
72.25 = 64 + b²
8.25 = b²
b = 2.9 ft
original b - new b = 6 - 2.9 = 3.1 ft
=> the boat's rate is 3.1ft/sec
Label each as either physical or chemical change.
a.corrosion of aluminum metal by hydrochloric acid
b.melting wax
c.pulverizing an aspirin tablet
d. digesting a Three Musketeersbar
e. explosion of nitroglycerin
f. a burning match
g. metal warming up, due to the burning match
h. water vapor condensing on the metal
i.the metal oxidizes, becoming dull and brittle
j.salt being dissolved by water
Answer:
corrosion of aluminum metal by hydrochloric acid - chemical change
melting wax - physical change
pulverizing an aspirin tablet - physical change
digesting a Three Musketeersbar - chemical change
explosion of nitroglycerin - chemical change
a burning match - chemical change
metal warming up, due to the burning match - physical change
water vapor condensing on the metal - physical change
the metal oxidizes, becoming dull and brittle - chemical change
salt being dissolved by water - physical change
Explanation:
A chemical change is one in which a new substance is produced and it is not easily reversible. A chemical change always goes with absorption or evolution of heat.
On the other hand, a physical change is one in which no new substance is formed and it is easily reversible.
The processes mentioned in the question were classified into physical and chemical changes as we can see in the answer section.

PLEASE HELP WILL MARK BRAINLIEST! 20 POINTS If the working-age population was 279 million of the 320 million people living in the United States and 122 million were employed while 14 million were unemployed, the unemployment rate would be approximately 11.5%. 10.2%. 5%. 4.8%. 10.29%.
Answer:
10.29%
Explanation:
Add 122 million and 14 million and you get 136 million. That is how many people are working and not working. Ignore the other information (279 million and 320 million) because those are misleading. Now do: 14/136 (leave out the millions) and you get 0.1029. Multiply by 100 and you get 10.29% or 10.2%.
Answer:
10.29%
Explanation:
14/(122+14)*100 = 10.29

Select two targets. Write two paragraphs, one for each target, identifying potential challenges that each target presents and describe possible methods to overcome those challenges. Use evidence from course content to support your responses.
Answer:
Explanation:
Target 1.1
By 2030, eradicate extreme poverty for all people everywhere is an extremely challenging target. First of all, there are almost 8 billions people on Earth. Each person in extreme poverty has different background and circumstances. It is difficult to come up with a plan that will help them all. The first step is international cooperation; involving rich countries giving ads to poorer countries.
Target 1.2
By 2030, reduce by half population living in poverty by national definitions is easier to accomplish than Target 1.1. The key here is "by national definitions." As different countries have different definitions for poverty, the standards are lower for poorer countries. Leaders in those countries will try to improve lives of their people so that they can be remembered as the ones who lift their countries out of poverty.

Which evils of modern society does Mr. Diamond cite as evidence that the Neolithic Revolution was a negative event in the history of mankind?
The evils of modern society referred to by Jared Diamond in his article "The Worst Mistake in the History of the Human Race" are:
Population GrowthHealth IssuesGross social and sexual inequalityDespotismIn his article, he describes the above challenges as a fall out of the Neolithic Revolution. The Neolithic Revolution is none other than the discovery of Agriculture by man.
His article visits evidence upon evidence using evolution, and findings from archeology to buttress his points.
1. Population Growth: His interpretation of this is that because man discovered agriculture, he shelved his nomadic lifestyle (hunting and gathering) in favor of sedentary existence. Because man no longer migrated from place to place, population density triggered around the location where he chose to settle.
2. James cites the following as evidence that agriculture created an upward trajectory in the occurrence of health issues:
first, while the nomadic man (hunter and gatherer) had and ate a variety of foods the sedentary (agriculturer) was limited to just a few carbohydrates (starch) based crops. Of course, this is an approximation but the point is very clear and near to the truth. second, increases in population densities leading to the spread of parasites and infectious diseases; third, the risk of death increased because of the dependence on just a few varieties of crops to propagate.3. James also posited that despotism and inequality are fallouts of Agriculture. Hunters and gathers, according to him, have no need to store food for prolonged periods of time. They depended on fresh intake of nutrients. Nature held the power of ownership of resources. Hence, there were no class divisions such as the rich and the poor, the weak and the powerful (politically speaking).
4. He also posited that under the nomadic culture, the job of the woman was mostly to transport babies as the tribes moved from one location to the other. Under the agricultural system, women became more like beasts of burden tasked with various kinds of agricultural routines including carrying very heavy loads from farm to sites of residence.
