Using x as the variable, write a formula to find the perimeter of the figure. Use the formula to find the perimeter. a regular d

Mamont248 [21]

Answer:

c. 12x; 111 cm

Step-by-step explanation:

The regular dodecagon has 12 sides. Each side has a length of x=9.25 cm, and we know that the perimeter of the figure is the sum of the lengths of all the sides: Therefore, since we have 12 sides, the perimeter will be given by the product between the length of each side, x, and the number of sides, 12:

$p=12 \cdot x$

and if we substitute x = 9.25 cm, we find

$p=12 \cdot 9.25 cm=111 cm$

Sever21 [200]

Answer: Charlie travelled for 96 minutes . <h2>Explanations : </h2>

Given

• A ride on a rental scooter cost $3 plus 11 cents per minute for a ride ,

,

• Total bill for Charlies ride = $13.56

,

• Let Charlies ride be equal to ,t minutes, long

,

• This is a linear function representing the total bill for Charlies ride as follows :

$3\text{ + }0.11t=13.56\text{ }$ <h2>Therefore , solving for t , we get that t = </h2> $\begin{gathered} 0.11t\text{ = 13.56 - 3 } \\ 0.11t\text{ = 10.56 } \\ \frac{0.11t}{0.11\text{ }}=\text{ }\frac{10.56}{0.11} \\ \therefore\text{ t = 96 minutes} \end{gathered}$

• t = 96 minutes ,

• This means that Charlie travelled for, 96 minutes ,.

,

• With a total bill of $13.56 , Charlies ride was 96 minutes long.

First multiply C by F by multiplying each row in C by each column in F:

12 * -2 + 0*0 + 1.5*2 12*0 + 0*8 + 1.5*1

1*-2 -6*0 +7.2 1*0-6*8 +7*1

to get a matrix of:

-21 1.5

12 -41

Now subtract that matrix from B:

2- -21 = 2+21 = 23

8 - 1.5 = 6.5

0.6 - 12 = -11.4

3 - -41 = 3+41 = 44

So you have:

23 6.5

-11.4 44

Which makes C the correct answer.
