D. is the answer to your question, welcome :3
The given situation above is an example of a geometric sequence with first term equal to three and the common ratio equal to 3. For the second day, Raul used 9 bags of cement. He used 27 bags on the third and 81 on the fourth. To answer the question, add the number of bags from second to fourth day. The answer is equal to 117 bags of cement.
Answer:
-57
Step-by-step explanation:
Put the value of x where x is and do the arithmetic.
-7·9 +6 = -63 +6 = -57
The equation for the sum of interior angles is :
Sum = (n-2) x 180, where n is the number of sides.
Replace sum with the given sum:
3960 = (n-2) x 180
Divide both sides by 180:
22 = n-2
Add 2 to each side:
24 = n
It has 24 sides.
For Each interior angle, divide the total sum by the number of sides:
3960 / 24 = 165 degrees
The interior and exterior angle needs to equal 180 degrees. To find the exterior angle, subtract the interior angle from 180:
180 - 165 = 15 degrees.
