Given:

Number of sides = 7

Apothem = 8 meters

Side length = 7.7 meters

To find:

The area of the regular polygon.

Solution:

We know that,

Area of a regular polygon is

[tex]A=\dfrac{1}{2}pa[/tex]        ...(i)

where, p is perimeter and a is apothem.

Perimeter of a regular polygon is the product of number of sides and side length.

[tex]p=7\times 7.7[/tex]

[tex]p=53.9[/tex]

Substituting p=53.9 and a=8 in (i), we get

[tex]A=\dfrac{1}{2}(53.9)(8)[/tex]

[tex]A=(53.9)(4)[/tex]

[tex]A=215.6[/tex]

Therefore, the area of the regular polygon is 215.6 m².

Two communication companies offer calling plans. With company x, it cost 35 cents to connect and then 5 cents for each minute.With company y, it cost 15 cents to connect and the 4 cents for each minute. Write and simplify an expression that represents how much more company x charges than company y, in cent, for n minutes

Answers

Answer:

34

Step-by-step explanation:

Subtract and divide

The amount of money company x charges than company y, in cent, for n minutes will be (20 + n) cents.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

With company x, it cost 35 cents to connect and then 5 cents for each minute.

And, With company y, it cost 15 cents to connect and the 4 cents for each minute.

Now,

Since, With company x, it cost 35 cents to connect and then 5 cents for each minute.

Hence, The cost for n minutes with company x is,

⇒ 35 + 5n

And, With company y, it cost 15 cents to connect and the 4 cents for each minute.

Hence, The cost for n minutes with company y is,

⇒ 15 + 4n

Thus, The amount of money company x charges than company y, in cent, for n minutes = 35 + 5n - (15 + 4n)

                     = 35 + 5n - 15 - 4n

                     = (20 + n) cents

A.

B.

C.
19%
D.

C.) 19% decrese

Step-by-step explanation:

575.00 - 465.75 = 109.25

109.25/575.00 = 0.19

0.19 = 19%

575.00 - 465.75 = 109.25

109.25/575.00 = 0.19 = 19%

Therefore, the percentage decrease of the amount of available credit in Dylan's account is 19%.
