Answer:
V = (2/9)s³
Step-by-step explanation:
The general formula for the volume of a pyramid is:
V = (1/3)(base area)(height).
Here, the length of a side of the square base is s, and so the area is A = s². For the height we use (2/3)s. Then the volume of the pyramid is:
V = (1/3)(s²)(2/3)s, or V = (2/9)s³
Answer:
C
Step-by-step explanation:
I'm just guessing
Since there are two negative signs in front of the 17 it becomes a positive and then since there are two after that becomes plus so 17+17.9 and u get 34.9
Two angles are complementary when their sum is equal to 90°.
So, ( 2x + 39 ) + ( 7x - 21 ) = 90°
9x + 18° = 90°
x = 8°
Putting value of x in the angles given :
( 2x + 39 )° = 2(8°) + 39° = 55°.
( 7x - 21 )° = 7(8°) - 21° = 35°.
Therefore, the angles are 55° and 35°.
Hence, this is the required solution.
The answer would be 31,115. You would add 100% to 27% to make 127% (1.27). Then you multiply 1.27 to 24,500 to get 31,115 as your answer.
