Javier estimates the square root of 18 in the following way:
√18=2√9=2*3=6
A: Explain why her reasoning is incorrect.

B: Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.

Answers

Answer 1

Step-by-step explanation:

√18 = √(2x9) = 3√2. so they pulled the 2 out of the square root incorrectly.

4x4 = 16

5x5 = 25

so √18 is between 4 and 5. closer to 4

Please write eight facts about: The Flow of Energy in a Food Chain.
_________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Answers

Answer:

Always linear...

Decreases with successive trophic level

Answer:

Food chains are very important for the survival of most species. When only one element is removed from the food chain it can result in extinction of a species in some cases.An example of a simple food chain would be: A plant grows using the sun's energy and nutrients from the soil. A rabbit eats the plant. A fox eats the rabbit. The fox dies and decomposes into organisms that feed the soil.A producer, which is able to produce its own food, is also called an autotroph. Every species in the ecosystem relies on producers for their existence.A producer is able to covert inorganic compounds into organic compounds. Without this process life could not exist.A producer can use either solar energy or chemical energy to convert organisms into usable compounds.Because the sun is necessary for photosynthesis, life could not exist if the sun disappeared.Consumers can be carnivores (meat eater only), herbivore (plant eater only), omnivore (eats animals and plants), and a scavenger (eats dead animals).Examples of omnivores (plant and animal eaters) are bears (which eat fish, insects, honey, moose, and grass), turtles (which eat crayfish, earthworms, lettuce, and algae), squirrels (which eat seeds, fruit, eggs, and insects), and monkeys (which eat fruit, leaves, and frogs).Examples of carnivores (animal eaters) include hawks, snakes, foxes, and spiders.Examples of herbivores (plant eaters) include rabbits, moose, cows, groundhogs, and grasshoppers.Decomposers, which feed on dead animals, break down the organic compounds into simple nutrients that are returned to the soil. These are the simple nutrients that plants require to create organic compounds.It is estimated that there are more than 100,000 different decomposers in existence.Al-Jahiz was a 9th century scientist who is responsible for introducing the concept of food chains.The food web, which is a concept that expands on the food chain, was introduced in 1927 by Charles Elton.Food chains can be short, or they can be long, depending on how many consumers can be eaten before one dies and begins to decompose.If a food chain were to continue too long, the energy would become less and less and it would not be very valuable to the animal at the end.

For the data set 1,7,7,7,8, the mean is 6. what is the mean absolute deviation?

Answers

Answer:

The answer is 2

Step-by-step explanation:

First you need to calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. All of the points add up to 10. Then you divide that number by how many points there are which is 5 and you get 2.

two passenger train traveling in opposite directions meet and pass each other. Each train is 1/18 miles long and is traveling at 40 miles per hr. How many seconds after the front parts of the trains will meet their rear parts pass each other.

Answers

9514 1404 393

Answer:

5 seconds

Step-by-step explanation:

Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...

time = distance/speed

time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s

That is, the rear part of each train will be at point A 5 seconds after the front part.

The rear parts will pass each other 5 seconds after the front parts meet.

Equation C: y = 6x + 9 Equation D: y = 6x + 2 How many solutions are there to the given set of equations?

Answers

Answer:

No solution

Step-by-step explanation:

Equation C :

y = 6x + 9

Equation D :

y = 6x + 2

By comparing both the equations with slope-intercept form of the equation,

y = mx + b

Where, m = Slope of the line

And b = y-intercept

Slopes of both the lines C and D are common as 6,

Therefore, both the lines will be parallel.

And the set of parallel lines has no solution.

Therefore, given set of equations have no solution.

What is the slope of the line?

Answers

Answer:

1/2

Step-by-step explanation:

y = mx + b is slope intercept form.

b = y intercept. where the line first passes through on the y axis

that number is 3.

y = mx + 3.

to find M (slope) you have to do RISE / RUN.

Run is going left or right from a point

Rise is going up or down from a point.

To make sure you find the slope, when you Rise and Run, it has to hit another point on the graph.

From the y - intercept 3, RISE (go up) 1 and RUN (go left) 2.

So, the slope is 1/2.

Write an essay that analyzes the rhetorical choices Fridman makes to develop his argument.In your response you should do the following:Respond to the prompt with a thesis that analyzes the writers rhetorical choices.Select and use evidence to support your line of reasoning.Explain how the evidence supports your line of reasoning.Demonstrate an understanding of the rhetorical situation.Use appropriate grammar and punctuation in communicating your argument.There is something very wrong with the system of values in a society that has only derogatory terms like nerd and geek for the intellectually curious and academically serious.A geek, according to Websters New World Dictionary, is a street performer who shocks the public by biting off heads of live chickens. It is a telling fact about our language and our culture that someone dedicated to pursuit of knowledge is compared to a freak biting the head off a live chicken.Even at a prestigious academic institution like Harvard, anti-intellectualism is rampant: Many students are ashamed to admit, even to their friends, how much they study. Although most students try to keep up their grades, there is a minority of undergraduates for whom pursuing knowledge is the top priority during their years at Harvard. Nerds are ostracized while athletes are idolized.The same thing happens in U.S. elementary and high schools. Children who prefer to read books rather than play football, prefer to build model airplanes rather than get wasted at parties with their classmates, become social outcasts. Ostracized for their intelligence and refusal to conform to societys anti-intellectual values, many are deprived of a chance to learn adequate social skills and acquire good communication tools.Enough is enough.Nerds and geeks must stop being ashamed of who they are. It is high time to face the persecutors who haunt the bright kid with thick glasses from kindergarten to the grave. For Americas sake, the anti-intellectual values that pervade our society must be fought.There are very few countries in the world where anti-intellectualism runs as high in popular culture as it does in the U.S. In most industrialized nations, not least of all our economic rivals in East Asia, a kid who studies hard is lauded and held up as an example to other students.In many parts of the world, university professorships are the most prestigious and materially rewarding positions. But not in America, where average professional ballplayers are much more respected and better paid than faculty members of the best universities.How can a country where typical parents are ashamed of their daughter studying mathematics instead of going dancing, or of their son reading Weber* while his friends play baseball, be expected to compete in the technology race with Japan or remain a leading political and cultural force in Europe?
