I think you forgot to square the 6. So V=(pi)*36*10 So when I multiply these numbers together the answer is actually 1,130.4 m³. I hope this helped you!
Answer:
C
Step-by-step explanation:
70+20=90 and thats a right angle which is 90°
We have x^2 + 2 · x · (11/2) + (11/2)^2 = - 24 + (11/2)^2;
Then, ( x + 11/2 )^2 = -24 + 121/4;
( x + 11/2 )^2 + 96/4 - 121/4 = 0;
( x + 11/2 )^2 - 25 / 4 = 0;
( x + 11/2 )^2 - (5/2)^2 = 0;
( x + 11/2 - 5/2)·( x + 11/2 + 5/2 ) = 0;
( x + 6/2 )·( x + 16/2 ) = 0;
( x + 3 )· ( x + 8 ) = 0;
x = - 3 or x = -8;
The first choice is the correct answer.
40 flights, you could use rates in this situation.
15 min*4=60 min=1 hr
10:15 multiply each side by 4
40 flights:60 minutes
