Answer:
the answer is (A) 14.13 cu. in
Step-by-step explanation:
Both of the other angles should be 45. 180-90=90. 90 divided by 2 equals 45
if 2 angles whose sums are 90 then the angles are Complementary Angles if the 2 angles whose sums are 180 they are Supplementary angles

Answer:
It approximately dropped 0.027777 per hour.
Step-by-step explanation:
First, we calculate the decrease.
Decrease = 11/40 = 0.275
Then, we calculate the time interval.
From 10 pm to 7:54 hours will be 9.54 hours
Time interval= (9 + 54/60) hours
Time interval=9.9 hours
Finally, we calculate how much it dropped each hour
0.275/9.9 ≈ 0.027777
So it approximately dropped 0.027777 per hour.
