find the circumference of a circle with an area of 530.93

Answers

Answer 1

A = π r^2
r^2 = A/π
r^2 = 530.93 / 3.14
r^2 = 169.08
r = 13

C = 2 π r
C = 2 (3.14)(13)
C = 81.64

answer
81.64 m

While attending a college football game, you think you can guess the attendance within 10% of the actual value. If the announced attendance is 65,000, within what number of people would your guess have to be in order for you to support your claim?

Answers

Answer:

13,000 People

Step-by-step explanation:

65,000 (0.1) = 6500

6500 (2) = 13,000

You multiply by 2 to get 10% above or below the announced attendance.

Answer:

6,500

Step-by-step explanation:

If you think you can guess the attendance within 10% of the actual value, then your guess would have to be within 6,500 of the actual attendance of 65,000 in order for you to support your claim. This is because 10% of 65,000 is 6,500. So if your guess is within 6,500 of the actual attendance, then you can support your claim.

Answers

intersecting means f(x)=g(x)

x²-2x-8=0
(x-4)(x+2)=0
x=4, or x=-2
when x=4, f(x)=g(x)=15

If the circumference of a circle measures 3/2 π cm, what is the area of the circle in terms of π?

Answers

Final answer:

The area of the circle with a circumference of 3/2 π cm is 9/16 π cm².

Explanation:

The question is asking about finding the area of a circle when the circumference is given. The formula to find the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle. Given that the circumference is 3/2 π cm, we can use this information to find the radius.

From the circumference equation, r = C/2π = (3/2π)/ 2π = 3/4 cm. Having the radius, we can then use the formula for the area of a circle, which is A = πr². As a result, the area of the given circle is π(3/4)² cm² which simplifies to 9/16 π cm².

The price of a pair of headphones is $49.99 before tax. Ron bought the headphones for a 50% discount. He then paid sales tax of 8% on the discounted price.

Part A: How much did Ron pay in sales tax? Show all work and steps in your solution.
Part B: What is the total amount that Ron paid for the headphones? Show all work and steps in your solution.

Answers

Part A:
Price before tax: $49.99
Discount: 50% of $49.99 = 50% * $49.99 = 0.50 * $49.99 = $25.00
Discounted price: $49.99 - $25.00 = $24.99
Tax on discounted price: 8% of $24.99 = 8% * $24.99 = 0.08 * $24.99 = $2.00

Part B:
Total price: $24.99 + $2.00 = $26.99

The cost of 7 drinks is $16.38. What is the cost of each drink?

$1.54
$1.88
$2.34
$2.73

Answers

the answer to thus question is $2.34

The cost of each drink if 7 drinks cost $16.38 is $2.34.

What is Division?

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that the cost of 7 drinks is $16.38. Therefore, the cost of each of the drink will be:

Cost of each drink = Cost of all the drinks / Number of drinks

= $16.38 / 7

= $2.34

Hence, the cost of each drink is $2.34.

A carpenter is creating a circular wooden table with a radius of 4 feet and needs to know the area of the table to purchase the correct amount of stain to finish it.

What is the area of the table?

Use 3.14 for π .

Enter your answer, as a decimal, in the box.

(?) ft²

Answers

Answer: The area of the circular wooden table = 50.24 ft²

Step-by-step explanation:

Given: The radius of the circular table = 4 feet

We know that area of a circle is given by :-

[tex]\text{Area}=\pi r^2[/tex]

Therefore, the area of circular wooden table is given by :-

[tex]\text{Area}=3.14(4)^2\\\Rightarrow\ 3.14\times16\\\Rightarrow\text{Area=}50.24\ ft^2[/tex]

The area of the circular wooden table = 50.24 ft²

Answer: 50.24

Step-by-step explanation:

We know: The radius = 4 feet and that the area of a circle = πr^2

Next: (π) 3.14 (4)^2

which we can simplify to be 3.14 * 16

= 50.24

58 people attend a banquet at Disney residents paid 13.00 and non residents paid 17.50. If Disney made 925.00 from ticket sales for the event how many residents and non residents attended

Answers

x= # of residents
y= # of non residents

QUANITY EQUATION
x+y= 58

COST EQUATION
$13.00x + $17.50y= $925.00

SOLVE FOR 1 VARIABLE
x+y= 58
subtract y from both sides
x= 58-y

SUBSTITUTE IN 2nd EQUATION
$13.00x + $17.50= $925.00
13(58-y) + 17.50y= 925.00
multiply 13 by all in parentheses
(13*58)+(13*-y)+17.50y= 925.00
754-13y+17.50y= 925.00
combine like terms
754+4.50y= 925.00
subtract both sides by 754
4.50y= 171
divide both sides by 4.50
y= 38 number of non residents

SUBSTITUTE TO FIND X
x+y= 58
x+38= 58
x= 20 number of residents

ANSWER: 20 residents and 38 non residents attended.

CHECK:

How much compound interest is earned on $2050 at 4% interest for 3 years, compounded annually? Give your answer in dollars and cents. Don’t forget to subtract P from A.

Answers

To solve for the amount + interest for compounding interest you will use this formula:
[tex]A = P ( 1 + \frac{r}{n}) ^{nt} [/tex]

Where A = Accrued amount
P = Principal amount
r = rate in decimal
t = number of years
n = compounding periods per unit of time
Your given:
P = $2050
r = 4% or 0.04
t = 3 years
n = 1 per yr
Now we insert that into your formula:
[tex]A = P ( 1 + \frac{r}{n}) ^{nt} [/tex]
[tex]A = 2050 ( 1 + \frac{0.04}{1}) ^{1.3} [/tex]
[tex]A = 2050 ( 1 + 0.04) ^{3} [/tex]
[tex]A = 2050 ( 1.04) ^{3} [/tex]
[tex]A = 2050 (1.124864 ) [/tex]
[tex]A = $2305.97 [/tex]

Now to get the interest just remember that:
I = A - P
I = $2,305.97 - $2,050
I = $255.97
So that is equal to 255 dollars and 97 cents

$255.97 is the correct answer

Dennis can load the car in 28 min. If Andy helps him it takes 21 min to load the car how long will it take Andy alone?

Answers

let the load car = y , and Andy will take time x (min.) to load the car
So,
    The rate of Andy to load the car = y/x

And we given that: Dennis load the car in 28 min.
So,
    The rate of Dennis to load the car = y/28

If both are loading the car in time = t = 21 min
then:
         y = (y/x) t + (y/28) t     ⇒ divide all equation by y and substitute with t
∴      1 = (21/x) + (21/28)     ⇒ multiply all equation by 28x
        28x = 21*28 + 21x
        28x - 21 x = 588
        7x = 588
∴      x = 84 min.

Which mean Andy will take 84 min. to load the car alone.

The sum of r and t is equal to 42. Let r = 25. What is the value of t?

Answers

r + t = 42
r = 25

Plug in 25 for r

(25) + t = 42

Isolate the t by subtracting 25 from both sides

t + 25 (-25) = 42 (-25)
t = 42 -25
t = 17

Hope this helps

Since r = 25, t must equal a number that, when added to 25, equals 42.

42 - 25 = 17. t must equal 17.

17 + 25 = 42.

456 000 has been rounded to the nearest thousand. What was the smallest possible number this could have been?

Answers

The smallest possible number could have been 455,500

Answer:

The smallest possible number this could have been = 455500

Step-by-step explanation:

456000 has been rounded to the nearest thousand.

If the value is more than 456500 the value rounded to the nearest thousand is 457000.

If the value is less than 455500 the value rounded to the nearest thousand is 455000.

In between 455500 and 456500 the value rounded to the nearest thousand is 456000.

So, The smallest possible number this could have been = 455500
