A flying disc has a circumference of 75.36 centimeters. What is the area of the flying disc? (Use 3.14 for .)

Hatshy [7]

The area of flying disk is 452.16 square centimeters

Step-by-step explanation:

The disc is in circular shape so we will use the formulas for circle in this question.

Given

Circumference = C = 75.36 centimeters

We have to find the area of the disc for which we have to find the radius first.

Let r be the radius

Then

Circumference is given by:

$C=2\pi r$

putting the values

$75.36 = 2*3.14*r\\75.36 = 6.28r$

Dividing both sides by 6.28

$\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm$

The area of circle is given by:

$A = \pi r^2$

Putting the values

$A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2$

Hence,

The area of flying disk is 452.16 square centimeters

Suppose that a cell phone monthly rate plan costs the user 5 cents per minute beyond a fixed monthly fee of $20. This implies th

nikdorinn [45]

Answer:

y = 20 + .5x

Step-by-step explanation:

Suppose that a cell phone monthly rate plan costs the user 5 cents per minute beyond a fixed monthly fee of $20. This implies that the relationship between monthly cost and monthly number of minutes is linear. Write an equation that relates total monthly cost to monthly minutes used.

Fixed monthly fee = $20

Fee per minute = $0.5

Number of minutes = x

Variable monthly cost = 0.5x

Let Total monthly cost = y

Total monthly cost = fixed monthly cost + variable monthly cost

y = 20 + .5x

Equation that relates total monthly cost to monthly minutes used is y = 20 + .5x

Mrs. Pahulick went to Super Buy to purchase the iPhone 12, which is typically $999.99. For one day only, it is on sale at a 15%

lana [24]

Answer:

$900.10

Step-by-step explanation:

15 percent of 999.99 = $849.15

(999 x 15)/100 = $149.85

849.15 with 6 percent sales tax is 900.10

What is the value of x? 45° ( 2x-5)°

AlekseyPX

(2x - 5)° + 45° = 180°

2x° + (-5 + 45)° = 180°

2x° + 40° = 180°

2x° = 180° - 40°

2x° = 140°

x° = 140 ÷ 2

x° = 70°

So, the value of x is 70°

Hope it helps and is useful :)

If the hockey team scores 9 goals in their next game, it means that; the mean would be the most affected.

<h3>How to find mean, median and mode?</h3>

We are given the data set as;

3, 6, 2, 1, 2, 3, 0, 4, 5, 1, 5, 4.

Let us rearrange in ascending order to get;

0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6.

The mean = (0 + 1 + 1 + 2 + 2 + 3 + 3 + 4 + 4 + 5 + 5 + 6)/12 = 3

Median = (3 + 3)/2 = 3

Mode = 1, 2, 3, 3, 5

Now, if they score 9 goals in their next game, it means that;

Mean = 45/13 = 3.46

Median = 3

Mode remains the same

Thus, mean will be the most affected.
