the diameter of a circle is 5 meters. What is the area?

Answers

Answer 1

Answer:

The area of the circle is 19.625.

Step-by-step explanation:

To find the area of a circle, you use the formula A=πr², so you need the radius. The radius is half of the diameter, so half of 5 is 2.5. Next, you just plug the numbers into the formula (I used 3.14 for pi). A=(3.14)(2.5²).A=(3.14)(6.25)A=19.625Round to your liking/whatever the question asks for and add the units the question asks for as well. If there aren't any offered in the question, just use units squared if you have to give any.

A rectangle has an area of square unit inside length of 2 1/4 unit find the other side length of the Rectangle

Answers

Answer:

Therefore, the other side length of the Rectangle b = 4 (4/9)

Step-by-step explanation:

Although crucial information that area of the rectangle is missing we can assume it be 10 square units for understanding purposes.

Let the sides of the rectangle be a and b.

Given a = 2 1/4 units

a = 9/4 units

b=?

Area of a rectangle = product of its sides = a×b

⇒ a×b= 10

⇒ 9b/4 = 10

⇒ b= 40/9 = 4 (4/9)

Therefore, the other side length of the Rectangle b = 4 (4/9)

The Great War was supposed to be the war to end all wars. In hindsight, we all know it wasn't. And that is why we commonly call it World War I. Knowing that, please respond to the following questions in a 5 sentence + paragraph (with a claim and history to back it up).
Why shouldn't the winner of the war seek reparations on the loser?
What is wrong with self-determination - allowing nations to decide what kind of country they want to be?
Why can't America practice isolationism? Along with that, why do we have to have alliances in the modern world?
Why didn't the carving up of the Ottoman Empire and Eastern Europe work in the Treaty of Versailles and prevent WWII?
And why do you think so many Germans and Italians listened to fascist leaders like Hitler and Mussolini? The term is attached if you are struggling with it (https://www.britannica.com/topic/fascism).

IK this is history but Math gets more help from people

Answers

I'll respond to each question as if it was a separate problem. I'll let you rewrite these concepts into a paragraph format.

War is costly in terms of lives and money. It would be nice if a country could repay somehow in the form of bringing lives back, but that's not possible. So naturally people turn to money as a way to get reparations. This is to rebuild things that were bombed or destroyed in some way. Despite the temptation to want to force (very punishing) reparations, history has shown that such crippling reparations will lead to the loser country to further crumble apart. As the country falls apart, undesirable forces will step in and may lead to further deterioration. Couple this with the Great Depression, and these two factors led to strong reasons why people turned to fascism. Keep in mind that such a transition was slow and over a long period of time. It didn't happen overnight. In short, crippling reparations may seem like a good idea, but ultimately they have very strong negative consequences later down the road. There's nothing wrong with self-determination because after all, it makes sense to let countries do what they want to do. No one country should dictate terms over what another country should or shouldn't do. However, there are limits of course. If Germany wants to own a piece of land that's part of Poland, then the German army can't simply walk in and take it. There are other limits of course so it has to be within reason. America is physically isolated from Europe, which allowed that country to stay out of much of WWI and WWII until the tail end of each conflict. Theoretically, there's nothing stopping any country from being isolated from any others; however, if that country wants to engage in world trade and negotiations, then it has to be more involved. So again, America or any other country, could close up its borders tightly and be on its own. But since it's more efficient to have trading partners, the United States is better off being connected with the world. Also, even if America closed up all its borders as tight as possible, it would not prevent something like events of Pearl Harbor from happening. That was the tipping point to push the US into WWII.I'm not too familiar with this aspect of WWII history, so I don't think I'll be much help here. But if I had to make a guess, it would be because carving up a country in which you have no stake in likely leads to the local population being unhappy in some way. It would be like someone coming into your house and saying which rooms were yours, what you could or couldn't use, etc etc. Refer back to the first response (item 1) above. In the end portion, I mentioned that crippling economic conditions are likely a very strong reason to have people turn to fascism. They likely were out of options and backed into a wall. During the depression, a vast majority of people were homeless and starving. A person in such a state is probably likely to turn to drastic measures.

Each of those responses are my own viewpoint of what I remember from history class. I recommend you rewrite these concepts into your own words, and also use online sources to provide citation as well.

Write the equation of a line passing through (-4.3) and perpendicular to -6x + 4y =-12.

Answers

Answer:

y=-2/3*x+1/3

Step-by-step explanation:

-6x+4y=-12

put into y=mx+b line equation

4y=6x-12

y=(6/4)x-(12/4)

y=(3/2)x-4

slope is 3/2

to find perpendiular line slope take the negative inverse.

-(2/3) = slope of perpendicular line

use line equation and solve for y-intercept (b)

3=(-2/3)*(-4)+b

3=8/3+b

b= 9/3-8/3 = 1/3 : 3 = 9/3 to allow for subrtaction of fractions.

Answers

Answers:

a) The difference in temperature is 25 degrees Fahrenheit. b) The temperature was rising fastest during interval 'a'

=========================================================

Explanations:

a) We subtract the y coordinates of the left and right endpoints. We get 65-40 = 25b) The fastest rising temperature will visually correspond to the steepest part of the curve. That would be region 'a'. After this interval, region b is still increasing, but not as much as the previous interval (since it's not as steep here). Then it gets less steep for region c, and d sort of flattens out as well. So during the morning hours it appears the temperature is going up the fastest.

Step-by-step explanation:

p - 3 = 5

p - 3 + 3 = 5 + 3

p = 8

3p = 30

3p ÷ 3 = 30 ÷ 3

p = 10

10 ≠ 8

p + 2 = 10

p + 2 - 2 = 10 - 2

p = 8

8 = 8

[tex]\frac{p}{8} =1[/tex]

[tex]8(\frac{p}{8}) =8(1)[/tex]

8 = 8

p = 8

p + 7 = 16

p + 7 - 7 = 16 - 7

p = 9

The length of two leg are given as AC = 55ft AB = 44ft. Hence, The length of the missing leg is 33 ft.

What is Pythagoras' Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Let's consider the right angle triangle ABC.

The length of two leg are given as

AC = 55ft

AB = 44ft.

[tex]|AC|^2 = |AB|^2 + |BC|^2 \\\\|55|^2 = |44|^2 + |BC|^2 \\\\ |BC|^2= 3025 - 1936\\\\ |BC|^2 = 1089\\\\ |BC| = \sqrt{1089} \\\\ |BC| = 33[/tex]

A is the amount = $10,200

rate r = 6.5%= 0.065

time t = years

n = 1/365 ((daily compounding)

Substitute into the formula and get Pincipal P

10,200 = P(1+0.065(365))^5/365

10200 = P(1+23.725)^0.01369

10200 = P(24.725)^0.01369

10200 = P(1.0448)

P = 10200/1.0448

P = 9,762.6

A coin is tossed and a spinner with three equal-sized sections labeled 3, 6, and 9 is spun. What is the probability of getting heads and a number greater than 3? Express as a fraction in simplest form.

Answers

Answer:

The answer is 1/3.

Step-by-step explanation:

A coin has either heads or tails. The odds of a coin getting heads is 1/2.

There are three equal-sized sections with numbers 3, 6 and 9 on the spinner. There are two sections with numbers greater than 3, which are 6 and 9. The odds of getting a number greater than 3 is 2/3.

To find the overall probability of both incidents occurring, the two fractions are multiplied together, which is 1/2 * 2/3 = 1/3

Answer:

0.333/1/3

Step-by-step explanation:

Well, the probability of getting heads is 1/2 since there are 2 sides to a coin. There are 2 numbers on the spinner greater than three (6,9) which is 2/3.

1/2 times 2/3=0.33. The probability of getting heads and getting a number that is greater than is 0.333 or 1/3.
