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:
and if we substitute x = 9.25 cm, we find

Answer:
<u><em>3.5 °C</em></u>
Step-by-step explanation:
- To find the answer multiply 3 and 7 to get the sum of the temperatures in the first seven days.
3 x 7 = 21
- Add 21 and 8 together to get the sum of the temperatures in the first 8 days.
21 + 8 =29
- Divide 29 by 8 to get the mean temperature for the first eight days.
29 ÷ 8 = 3.5
3.5 °C
$21.21 × 6 = $127.26
$127.26 ÷ 7 = $18.18 cost of 1 pillow at Jenson's.
You multiply the cost of the pillow at Harrison's, $21.21, by the amount of pillows you can buy at Harrison's, 6.
Then divide the answer by the amount of pillows you can buy at Jenson's, 7. The final answer is the cost of 1 pillow at Jenson's.
