What is the best approximation for the circumfrence of a circle with a diamiter of 400 inches

Answers

Answer 1

Answer:

$\bf \textit{circumference of a circle}\n\n C=\pi d~~ \begin{cases} d=diameter\n[-0.5em] \hrulefill\n d=400 \end{cases}\implies C=400\pi \implies C\approx 1256.637$

Why are 1,4,9,16,and 25 sometimes are called perfect square please HELP ME!!!!!!

Answers

They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25
16 is 4 bc 4(4) is 16
9 is 3 bc 3(3) is 9
1 is 1 bc 1(1) is 1

A chess club has 500 members but is losing 30 members each year. A computer club has 150 members and is gaining 20 members per year. Write and solve an equation to find the number of years it will take for the two clubs to have the same number of members.

Answers

Answer:

7 years

Step-by-step explanation:

Given: A chess club has 500 members but is losing 30 members each year. A computer club has 150 members and is gaining 20 members per year

To Find: Write and solve an equation to find the number of years it will take for the two clubs to have the same number of members

Solution:

Total members in chess club= 500

chess club loosing members each year = 30

Number of members in chess club in year $\text{x}$

$500-30\text{x}$

Total members in Computer club= 150

chess club gaining members each year = 20

Number of members in chess club in year $\text{x}$

$150+20\text{x}$

Now,

When chess club and computer club have equal number of members

$500-30\text{x}$ = $150+20\text{x}$

$500-150=30\text{x}+20\text{x}$

$350=50\text{x}$

$\text{x}=7$

So,

It will take 7 years for two clubs to have the same number of members.

Well for this a t-chart type of graph would help but here's how you can do it:

key: ChC = chess club
CmC = computer club

ChC = 500 members ChC = losing 30/yr
CmC = 150 members CmC = gaining 20/yr

year 1 : ChC CmC
members: 470 / 170

or.... you can scrap that, here's the simpler version :
500 - 30x = 150 +20x

solution: x = 7

Hope this helps!

Provide an example of a real-world relationship where there is no clear independent or dependent variable.

Answers

Answer:

Price and Demand

Step-by-step explanation:

We need to find a real-world relation in which the independent and dependent variables are not clear.

Let us consider, the price and demand relationship of a product.

In this relation, sometimes the demand of the product depends on its price and sometimes the price of the product varies according to its demand.

Thus, the independent and dependent variables changes according.

So, there is no clarity of the independent and dependent variables in the relation between the price and demand of a product.

If you consider humans, a single human is not capable of doing everything.

In Some ways he is dependent on other humans for different purposes.

But you can say that he or she is Independent , he or she has got his or her unique identity by saying he has got different features like body structure, appearance, Face, eyes etc... . He or She is different from others. So this way he is Independent,

But by considering man as Social animal , you can say that we humans are not independent but dependent on each other for survival or for our existence on this planet called earth.

→→A Single Human ⇒ Humans( there is no clear independent or dependent variable)

Heres 1. Use the table and the graph to answer the questions.
(a) What is the rate of change for each function? Show your work.
(b) Which function has the greater rate of change?
can you help me do these things

Answers

For the rate of change of Function 1, it is 2 because when I did delta y over delta x (3/-1)-(5/-2) i got negative 2 over negative 1. Two negatives equal a positive. For the rate of change of Function 2, it is 4. I picked two points that can even meet. Then I use the formula of rise over run to comes out as 4/1 simplified to 4. So Function 2 has the greater rate of change.

Answer:

The rate of change of first function is -2.

The rate of change of second function is 4.

Function 2 has greater rate of change.

Step-by-step explanation:

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the formula for rate of change is
