Answer:
Average growth= 11.20 feet
Step-by-step explanation:
<u>First, we need to calculate the total growth during those 312 years:</u>
<u></u>
Total growth= 3,512 - 18
Total growth= 3,494 feet
<u>Now, the average growth:</u>
<u>Average growth= total growth / number of years</u>
Average growth= 3,494 / 312
Average growth= 11.20 feet
One and three sixth because u simplify the two fractions
Answer:
-3 + (n-1)(-4)
Step-by-step explanation:
We follow the formula.
a1 + (n-1)d
d is the common difference.
<h2><u>Solu</u><u>tion</u><u>:</u></h2>
360° ÷ 10 ÷ 2 = 18°
So the length of the decagon side is:
10 × tan18° × 2 = 20 × tan18°
The area is: ½ × 20 × tan18° × 10 × 10 = 1000 × tan18°
≈ 324.9
.: <u>3</u><u>2</u><u>4</u><u>.</u><u>9</u> is the final answer.
