Given:
The system of equations that represent the constraints for the given situation is
To find:
The solution of given system of equations.
Solution:
We have,
...(i)
...(ii)
Multiply equation (i) by 4.
...(iii)
Subtracting (iii) from (ii), we get
Divide both sides by 12.90.
Put this value in (i).
The solution of system of equations is x=1.5 and y=2.75. It means, the yards of silk are 1.5 and yards of cotton are 2.75.
Answer:
Given speed of trolley = 125 meters per minute
Now we know that
Distance= Speed x time
Thus for the first case since the time of travel is less than 450 seconds thus the distance traveled is less than
Distance < 2.083 x 450 =937.5 meters
hence depending on the given information we cannot come to any conclusion weather the distance travelled is less than 800 m or greater than 800 m.
For the second case
since the time of travel is greater than 400 seconds
Thus the distance traveled is
which is greater than 800 meters.
Answer:
2/9
Step-by-step explanation:
Total outcome = 36
Sum of 7 = 6
Prob of sum of 7 = 6/36
Sum of 11 = 2
Prob of sum of 11 = 2/36
Prob of sum of 7 or 11 = 6/36+2/36
Prob of sum of 7 or 11 = (6+2)/36
Prob of sum of 7 or 11 = 8/36 = 2/9
