What is the density of the rock sample shown in the illustration above? F 0.2 g/cm 3 G 40 g/cm 3 H 5.0 g/cm 3 J 1.43 g/cm 3
Answers
Answer:
5 g/cm³
Explanation:
Density is the amount of matter contained by an object in a certain space. Density is the ratio of mass to volume. Density is given by the formula:
Density = mass / volume
We can see from the question, that initially the measuring cylinder contained a liquid with a volume of 100 cm³, but after the rock sample was immersed in the liquid, the volume rised up to 140 cm³. Hence:
The volume of rock sample = 140 cm³ - 100 cm³ = 40 cm³
Also, initially, the balance was at 0 g, but after placing the rock sample, it was 200 g. Hence:
mass of rock sample = 200 g
Therefore, Density of rock sample = mass of rock sample / volume of rock sample = 200 g / 40 cm³ = 5 g/cm³

Answers
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The best soil for agriculture in Mesoamerica was found in the southern highland valleys. The soil had been enriched through volcanic eruptions, while the mid climate made the area an ideal place for people to settle.
This is completely correct, Volcanic eruptions produced ash that spread throughout the Mesoamerican region.
Let's have in mind that Mesoamerica (modern-day México) was a region with major volcanoes in the area. The highest peak in México is the volcano "Citlaltepetl," better known as "Pico de Orizaba"(Orizaba Peak). Then, we find two impressive volcanos that divide the state of México and México City with the state of Puebla: the impressive Popocatepetl and the Iztazihuatl.
These volcanoes were very active in Mesoamerican/Precolumbian times and allowed Native Indians to grow quality cash crops.

You would expect to see all of the following in a patriarchal society, except __________.

B. fewer educational opportunities for women
C. more social marginalization for women
D. equal representation for women in business
Answers
You would expect to see all of the following in a patriarchal society, except more social marginalization for women.
What do you mean by patriarchal society?A patriarchal society is a society controlled by men in which the male elder has authority over the family group.
Patriarchy is obligated to protect and care for the woman's mental, physical, spiritual, and financial well-being; failure to do so will result in genuine long-term harm to the female's mind and body.
Walby discusses patriarchy's six "structures": paid work, housework, culture, sexuality, violence, and the state. In terms of their interrelationship, Walby contends that each of these structures has an impact on the others while remaining relatively autonomous.
Therefore, patriarchy is simply a protective social role and social construct that evolved over time.

After 4 rolls, what is the percent probability that Amy has won more points than Rob? Express your answer to the nearest hundredth
Answers
Answer:
60%
Explanation:
probability = number of favorable outcomes /number of outcomes
There are four prime numbers from 1 to 10
There are 5 even numbers from 1 to 10
Therefore in one roll of the dice there is a 40% (4/10)probability that Rob would win and there is a 60%(1-0.40) probability that Amy would win
If the dice is rolled 4 times, the probability that Amy has more points than Rob remains 60%

The correct answer to this open question is the following.
My opinion about this fake news is the following.
As ridiculous as it sounds, people are so immersed in social media these days and have lost the capacity to discern the good from the bad from the ugly.
It is incredible the number of news, fake news, and "in-between news" that daily appear in social media, and that news are taken as valid, knowing that social media is not a reliable source of information. Everybody can post what they want and it could go viral. That is not a big risk, but great danger.
The thing is that people are giving their power of discernment away and is fascinated with sensationalism, They like drama, and the more they get, the more they like and demand.
The fake news below related to the pandemic may have been responsible for the spread of the virus and contamination of more people.
It is necessary that when faced with very alarming news on a particular subject, such as fake news about the coronavirus, first check the source of the news.
As this fake news was propagated by a world political leader, people tended to believe and pass on this news, as the country's president has a voice to influence thousands of people, even if their opinions are unfounded and false.
Therefore, it is necessary to check the sources of viral news and investigate if there was any communication from official bodies on the subject in question, as in the case of the scientific community, which refuted fake news about the pandemic.
