14. Sam bought 30 pounds of produce to feed his hippo. Bananas cost $1 per pound; guavas cost $2 per pound; and kiwi costs $3 per pound. Sam spent $46. The bananas weigh twice the weight of the guavas and kiwi combined. Which system can be used to find how many pounds of each fruit Sam bought?

Answers

Answer 1

The system of equation that can be used to find how many pounds of each fruit Sam bought include:

x + y + z=30

x + 2y + 3z = 46    

x = 2y+2z      

How to illustrate the equation?

let x =  Number of pounds of bananas

y = Number of pounds of guavas

z = Number of pounds of dragon fruit

According to the question,

x + y + z = 30     (i) (total fruits bought = 30 pounds)

Bananas cost $1 per pound; guavas cost $2 per pound; and dragon fruit costs $3 per pound and total cost = $46.

∴ x + 2y + 3z = 46         (ii)

Also, weight of the bananas = 2 (weight of the guavas + weight of dragon fruit)

∴ x = 2(y + z)

⇒x = 2y + 2z       (iii)

from (i), (ii) and (iii)

x + y + z=30

x + 2y + 3z = 46    

x = 2y + 2z      

are the equations for the required system.

Africa is home to a diverse and extensive drainage system, consisting of numerous rivers and basins that play a crucial role in the continent's ecosystems and livelihoods. Here are some of the major drainage systems and rivers in Africa:

1. Nile River: The Nile is the longest river in Africa and the world, spanning over 6,650 kilometers. It flows through eleven countries, including Egypt, Sudan, Ethiopia, and Uganda, before emptying into the Mediterranean Sea. The Nile is of immense importance for agriculture, transportation, and hydroelectric power generation.

2. Congo River: The Congo River is the second-longest river in Africa and the world's deepest river. It flows through the Democratic Republic of the Congo and forms the border with several neighboring countries. The Congo River Basin is the world's second-largest rainforest region and is vital for biodiversity and local communities.

3. Niger River: The Niger River is the third-longest river in Africa, flowing through countries such as Guinea, Mali, Niger, Nigeria, and Benin. It supports agriculture, fishing, and transportation, and is a lifeline for millions of people in the region.

4. Zambezi River: The Zambezi is the fourth-longest river in Africa, running through six countries, including Zambia, Zimbabwe, and Mozambique. It is known for its spectacular Victoria Falls and provides water for irrigation, hydroelectric power generation, and wildlife habitats.

5. Limpopo River: The Limpopo River forms part of the border between South Africa and Zimbabwe, flowing into Mozambique and eventually reaching the Indian Ocean. It plays a critical role in the region's agriculture, wildlife conservation, and local communities' livelihoods.

6. Orange River: The Orange River is the longest river in South Africa, originating in Lesotho and flowing through Namibia before reaching the Atlantic Ocean. It supports irrigation projects and hydroelectric power generation, and is important for agriculture and mining in the region.

These rivers are part of larger drainage basins that contribute to the water cycle, provide habitats for diverse flora and fauna, and sustain human populations through agriculture, transportation, and hydroelectric power. They are essential for both the ecological health and economic development of Africa.

Why do tropical cyclone Florence develop in late summer

Answers

Answer: Tropical cyclones require warm surface waters

Explanation:

Extremely mountainous, humid and wet environment. Within this environment, wind speeds are low, but rainfall is high. Water evaporates quickly in this environment, due to underground volcanic activity that turns standing water into steam. Both visibility and the ability to breath are poor at all elevations. Higher elevations are covered in thick vegetation, tall trees, and fast growing invasive vines. Daily temperatures range from over 100 degrees fahrenheit to -20 degrees fahrenheit. Due to the high levels of steam and constant underground volcanic activity produced in this environment, it is not uncommon for mountain sides to erode without warning. The sun sets for 12 hours total in this environment. Despite the harsh conditions, the environment is livable.

They had exceptionally strong bodies, such as strong legs, massive hands, thick skin, and more hairs on their bodies, as well as prolonged maturation periods, which allowed them to survive in exceedingly hostile environments. For example, strong legs helped them climb mountains, large and strong hands let them hold mountains and other objects, thick and hairy skin protected them from harsh winters, and a longer maturation phase allowed them stay fit and strong for longer periods of time.

They possessed larger brains and the ability to create tools that assisted them in survival. Because of their big brain capacity, they developed cognitive abilities such as how to avoid rain and severe winters, therefore they began living in caves. They were able to build caves (by scratching and splitting rocks with tools) that protected them from the sun, winters, rain, and wild animals by using tool-making techniques.

The use of different or better analytical techniques might have made a difference in preventing the events of 9/11.

It is challenging to provide a definitive answer as the events surrounding 9/11 involved complex factors and intelligence failures. However, the use of different or enhanced analytical techniques could have potentially made a difference in identifying and preventing the terrorist attacks.

Improved data analysis, intelligence sharing, and collaboration among intelligence agencies might have led to a more comprehensive understanding of the threat posed by the perpetrators. Advanced technologies for data mining, pattern recognition, and predictive analytics could have potentially identified suspicious activities, connections, or anomalies that could have raised red flags.

Furthermore, an increased emphasis on information fusion and integration, along with effective communication channels, might have facilitated the timely dissemination of critical intelligence among relevant stakeholders.

A. gravitational potential energy released as heat during its formation stages, still being re-leased.B. heat caused by friction between oppositely directed winds at mid-latitudes.C. heat generated in the interior by the same electrical currents that generate the planet's mag-netic field.D. chemical reactions between methane, ammonia, and water in the planet's atmosphere and clouds.

Answers

The primary source of excess heat emitted by Jupiter is due to gravitational potential energy released as heat during its formation stages, still being re-leased. So option a is correct.

The source of excess heat emitted by Jupiter, above that which is absorbed as sunlight and reemitted, is thought to be gravitational potential energy released as heat during its formation stages, still being re-leased. This is due to the fact that Jupiter is made up of gases, which are extremely compressed due to its immense gravity. This compression leads to a large increase in temperature and thus the release of heat.

The heat released during Jupiter’s formation is still being released today, as the planet slowly cools down. This is the primary source of excess heat emitted by Jupiter, and it is estimated that approximately two-thirds of the heat emitted by Jupiter is due to this process.

what does the oceans connection to earth's water reservoirs through evaporation and precipitation tell you about the oceans role in the water cycle

Answers

Answer:

The oceans are, by far, the largest storehouse of water on earth — over 96% of all of Earth's water exists in the oceans. Not only do the oceans provide evaporated water to the water cycle, they also allow water to move all around the globe as ocean currents.

Explanation:

The ocean is a huge storehouse of water

When we talk about the water cycle, we must consider both where water is stored in pools, and the fluctuation of water between those storehouses. Much more water is "in storage" for long periods of time than is actively moving through the cycle. It is estimated that of the 332,500,000 cubic miles (mi3) (1,386,000,000 cubic kilometers (km3)) of the world's water supply, about 321,000,000 mi3 (1,338,000,000 km3) is stored in oceans. That is about 96.5 percent of all Earth's water. It is also estimated that the oceans supply about 90 percent of the evaporated water that goes into the water cycle.

The water in the oceans is saline (saltwater). Saline water contains significant amounts (referred to as "concentrations") of dissolved salts. In this case, the concentration is the amount (by weight) of salt in water, as expressed in "parts per million" (ppm). Water is saline if it has a concentration of more than 1,000 ppm of dissolved salts; ocean water contains about 35,000 ppm of salt.

why does Ramamurthy think it is important to analyze gender and race in relation to production.​

Answers

Answer:

Read below

Explanation:

Without additional context, it's difficult to know exactly which Ramamurthy is being referred to or what specific production is being discussed. However, in general, analyzing gender and race in relation to production can be important for a number of reasons.

Firstly, it can help identify patterns of discrimination or bias that may be present in the production process or in the industry as a whole. For example, if women or people of color are consistently underrepresented in certain roles or are paid less than their white or male counterparts, this could be an indication of discrimination or bias.

Secondly, analyzing gender and race can also help ensure that productions are more representative and inclusive. If the production team is diverse and reflects the experiences of a wider range of people, this can help ensure that the final product is more nuanced and thoughtful in its approach to issues related to gender, race, and other forms of identity.

Finally, analyzing gender and race can also help create opportunities for marginalized communities to participate in the production process and gain access to jobs and other resources. This can help address systemic inequalities and promote greater social and economic equity.
