D
Step-by-step explanation:
The line is going through the origin.
C. Find the sum of the two horizontal in the summer for two vertical vectors.
Step-by-step answer:
Answer to problems of this kind is the reciprocal of the harmonic mean of the time required.
We need to find the average of the speeds, not the average of the time.
The respective speeds are 1/3 and 1/4.
The average of the speeds is therefore (1/3+1/4)/2 = 7/24 (harmonic mean of the time taken).
The time required is therefore the reciprocal of the unit speed,
T = 1/(7/24) = 24/7 = 3 3/7 minutes, or approximately 3.43 minutes.
Answer:
C
Step-by-step explanation:
the volume of the cylinder is 3769.91
the volume of the cube is 1000
so the cylinder's volume is clearly larger than the cube's volume.
