Tina and Kylie saw an ad on television comparing different brands of
paper towels. They decided to run their own experiment to see
which towel could absorb the most liquid. They took several brands
of paper towels and cut them into equal sized strips. They put the
strips in small containers. Next they poured water into each
container. After 2 minutes, they pulled the strips out and measured
how much water was left. What was one variable they forgot to
control?

Answers

Answer 1

Answer:

They forgot to measure the amount of water poured into each container.

Explanation:

When an experiment is set up, all variables must be established in the same proportion for all experimental units. In this case, for the experiment to be efficient and present true results, it is important that the paper towel strips have the same size, the containers where they will be inserted are the same and they are tested in the same amount of water, that is, each container must contain the same amount of water. However, the amount of water was not measured in the above experiment and this was the variable that the researchers forgot to control, which will harm the veracity of the results.

I believe the answer to be “greywater”

Hope that is correct.

BRAINLY IS APRECIATED!!!

Brown water is Minerals, sediment, or rust that accumulates in the water mains over time is the cause of brown or discolored water. And is not good to use for drinking and/or washing clothing. But, it is okay to shower in and use in toilets.

That makes BROWN WATER an incorrect answer.

Groundwater is used for many things such as watering plants, and drinking water for 99% of rural areas. Groundwater is not used in washing machines but many people are trying to revert to groundwater for sewage.

That makes GROUNDWATER an incorrect answer.

Ethanol is used for drinks, paint, caned fruit and sugar.

That makes ETHANOL an incorrect answer.

Black water is waste water from bathrooms and toilets that contains faecal matter and urine.

That makes BLACKWATER an incorrect answer.

Grey water is used for washing but not sewage.

3. The transatlantic slave system had tremendous effects on the peoples of the Americas, Europe, and Africa.

Develop an argument that evaluates the extent to which the transatlantic slave system affected culture during the period from ca. 1450 to 1750 CE.

Explanation:

In Africa, the slave trade had disastrous consequences. Rebel groups and tribal groups who benefited financially from the slave trade created an environment of anarchy and brutality. Throughout much of west Asia, population reduction and a persistent fear of imprisonment caused severe economic growth nearly impossible.

Women during the pregnancy period and men who would usually be starting families made up a significant number of those kidnapped in Africa. People who were old, disabled, or otherwise completely reliant who may have been less able to participate to their communities' health of the economy were often left behind by European slave owners.

Many people, businesses, and countries benefited greatly from the atlantic slave trade. However the brutal human trafficking and huge amount of deaths that resulted ultimately ignited well structured resistance to the trade.The slavery was abolished by the British in 1807. Imprisoned citizens in Former colonies were liberated by another legislation enacted in 1833.

In 1808 Congress passed a law prohibiting the spread of slavery into the U. S. Though the law passed it not end slavery completely.  Other nations, including Spain, Netherlands, Sweden, and France, had enacted legislation prohibiting the expansion of slavery by the 1820s.

However, since there was still a large market for enslaved people and money to be made from trading in them, such legislation did not necessarily put an end to slavery. The atlantic abolition of slavery was eventually abolished in the late 1800s thanks to new legislation and continuing protection measures.

Answer:

m<MON = 100°

Explanation:

Given:

Area of shaded sector LOM = 2π cm²

NL = 6 cm

Required:

m<MON

Solution:

m<MON = 180° - m<LOM (angles in a straight line)

We don't know m<LOM. Therefore, let's find m<LOM.

Area of a sector = θ/360 × πr²

Area of sector LOM = 2π cm²

r = 3 cm

θ = m<LOM = ?

Plug in the values

2π = m<LOM/360 × π × 3²

2π = m<LOM/360 × 9π

2π = m<LOM × 9π/360

2π = m<LOM × π/40

Multiply both sides by 40

2π × 40 = m<LOM × π

80π = m<LOM × π

Divide both sides by π

80π/π = m<LOM

80 = m<LOM

m<LOM = 80°

✔️m<MON = 180° - m<LOM (angles in a straight line)

Substitute

m<MON = 180° - 80°

m<MON = 100°

Hannah and Anthony are siblings who have ages that are consecutive odd integers. The sum of their
ages is 92. Which equations could be used to find Hannah's age, h, if she is the older sibling?

Answers

Answer:

H + 2 + A = 92

Therefore, Hannah is 47 years old and Anthony is 45.

Explanation:

Since Hannah and Anthony are siblings who have ages that are consecutive odd integers, and the sum of their ages is 92, to determine which equations could be used to find Hannah's age, H, if she is the older sibling, the following calculation:

H + 2 = A

H + 2 + A = 92

H + A = 90

90/2 = A

45 = A

45 + 2 = H

47 = H

Therefore, Hannah is 47 years old and Anthony is 45.

During a meeting, a co-worker introduces herself as a native of Brazil who moved to America with her parents when she was three months old.
What is this co-worker describing?
ОА.
her master status
OB. her social role
O c. her ascribed status
OD.
her achieved status

Answers

Answer:

The correct answer is C. Her ascribed status.

Explanation:

Ascription is the acquisition of a social position and status without being subject to personal influence, as is the case with inheritance, gender or age. This is in contrast to acquisition, in which personal influence does play a role and the social position is determined by performance and capacities.  

Where in class society birth determined the class to which one belonged, this changed with the advent of industrial society with its market economy. Capacities and achievements became increasingly important and there was a shift towards meritocracy.

Answers

Answer:

A. They have different backgrounds, educations, and lifestyles.

Explanation:

A corporation can be defined as a corporate organization that has facilities and owns or controls assets used for the production of goods and services in at least one country other than its headquarter (home office) located in its home country.

This ultimately implies that, a corporation is a corporate organization that owns or controls its business in two or more countries.

Generally, a corporation is considered to be perpetual in nature and it is a body that comprises of a group of people such as directors, shareholders etc., who act as a single entity.

Sociology can be defined as a social science that deals with the study of the socio-cultural interaction of humans with respect to the structure, functioning and development of their society.

The main purpose of sociology is to develop and enhance human knowledge or understanding of important socio-cultural processes through the gathering and analysis of all aspects of the social life of the people living in a society.

A social group refers to two or more people (individuals) that shares similar characteristics, interacts with one another based on mutual understanding and expectations while collectively possessing a sense of unity.

This ultimately implies, a social group share a common identity, sense of unity and backgrounds.

Hence, employees of a big corporation are not considered a social group because they have different backgrounds, educations, and lifestyles.

Answer:  A.) They have different backgrounds, educations, and lifestyles.

Several studies have been conducted on human memory and on subjects' propensity to remember erroneously events and details that did not occur. Elizabeth Loftus performed experiments in the mid-seventies demonstrating the effect of a third party's introducing false facts into memory.4 Subjects were shown a slide of a car at an intersection with either a yield sign or a stop sign. Experimenters asked participants questions, falsely introducing the term "stop sign" into the question instead of referring to the yield sign participants had actually seen. Similarly, experimenters falsely substituted the term "yield sign" in questions directed to participants who had actually seen the stop sign slide. The results indicated that subjects remembered seeing the false image. In the initial part of the experiment, subjects also viewed a slide showing a car accident. Some subjects were later asked how fast the cars were traveling when they "hit" each other, others were asked how fast the cars were traveling when they "smashed" into each other. Those subjects questioned using the word "smashed" were more likely to report having seen broken glass in the original slide. The introduction of false cues altered participants' memories.

Answer & Explanation:

C) They used modern technology to improve prevention programs and screen travelers.

They quickly contained Ebola in a little span of 3 years. The plague lasted from December 26th, 2013 to June 9, 2016. In 2016 all cases were confirmed to be taken care of, as the majority had herd immunity. There were only 11,323 lost ones during this time period. This may sound like a lot, but, so far in our outbreak, which has lasted from December 2019 to the current time, May 19, 2021. It's not even fully cured and we're sitting on a 587,000+ count with over 33 million cases! It's been less time than the Ebola and we've managed to rise numbers in this thing. However, with the help of technology, we can find vaccines for these diseases and help people to stay safe as well.

Remember, stay safe! This vaccine is out! Make sure to get yours as soon as you possibly can, and if you don't, still stay safe! Wear your mask or just keep your distance from those you don't know. Do simple things like coughing or sneezing into your elbow or into a tissue, it helps to keep your loved ones, yourself, and the people around you safe.

The correct answer to this open question is the following.

Although there are no options provided we can say the following.

One type of society that's benefits outweighs the costs is the Agricultural society.

The reason why in these agricultural societies the benefits outweigh the costs is that farmers produce crops and cattle to trade or exports, but also they can use this food for their own consumption so they can feed their families and have this necessity covered.

So today these societies can have their basic necessities covered and trade another percentage of their production to generate a profit.
