First let do the whole area 100*75 = 7500 m²

Now let's calculate the area of the Arena Diameter (A=πr²)of 50 m .

A = 3.14*25 (half the diameter of 50) = 78.5 m² and now only half if overlapping, thus divide by 2 = 39.25 m²

Now we should be able to deduct 7500 m² - 39.25 m² = 7460.75 m²

Which type of data would be best displayed in a box plot

Mashcka [7]

The type of data that would be best displayed in a box plot is the number of votes received by each of four candidate.

A box plot is used to study the distribution and level of a set of scores. The scores are distributed into 4 groups. Each group has a value of 25%

The whiskers represent the minimum and maximum scores. On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.

Please help i need it

vichka [17]

Answer:

x = 100

Step-by-step explanation:

The area of the left square is 3600

A =s^2

3600 = s^2

Taking the square root of each side

60 =s

The area of the right square is 1600

A =s^2

1600 = s^2

Taking the square root of each side

40 =s

Adding the lengths

60+40 =x

100 =x

How did they get that answer? please answer

OverLord2011 [107]

Answer:

Look at my explanation

Step-by-step explanation:

The circumference of a circle is 2πr, so you can set it up like this since the circumference was 22π.

2πr = 22π

divide both sides by 2

πr = 11π

divide both sides by π

you get r = 11

So your radius is 11.

To find the area, you must do πr^2 ("^2" means squared)

if you substitute 11 for r you get

11π^2

you can do 11 squared first

11^2 = 121

the area of the circle = 121π

Keep in mind that they said to use 3.14 for π

so you can do 121 x 3.14

Final Answer: 379.94

Jun wei has 12 more 10 cents coins than 20 cents coins. the total value of all the coins is $5.40. find the total number of coin

DochEvi [55]

Jun Wei has a total of 40 coins. An algebraic expression or equation with the given information is formed to calculate the total number of coins.

<h3>What is an algebraic expression?</h3>

An algebraic expression is the combination of one or more variables, coefficients, and constants separated by operators. Each of them is called terms of the expression.

Eg: a + 6x + 5y + 2

Here there are 4 terms with 3 variables, 3 coefficients, and one constant.

<h3>Calculation:</h3>

Given that,

Jun Wei has 12 more 10 cents coins than 20 cents coins.

So,

Consider the number of 20-cent coins = x

Then, the number of 10 cent coins = x + 12

It is given that the total value of all the coins is $5.40.

Where 1 $ = 100 cents. That implies, $5.40 = 540 cents

So,

the total value of the coins = 540 cents

⇒ 20(x) + 10(x + 12) = 540

⇒ 30x = 540 - 120

⇒ 30x = 420

∴ x = 40

Hence, there are 40 coins with Jun Wei.
