Rate of fill-up = 1/44 = 1/44 * 77/77 = 77/3388
Rate of emptying = 1/77 = 1/77 * 44/44 =44/3388
Combined Rate of Fill-up = 77/3388 - 44/3388 = 33/3388 = 3/308
Time for combined fill-up = 308/3 = 102.6667 hours = 102 hours and 40 minutes
27202 - 3489 you can't do 2-9 so you cross out the 0 next to it and put it into a 10 and then turn your to into a 12 so 12 - 9 is 3 then since you have your 0 turned into 10 you do 10-8 you would you get 2 then you can't do 2-4 so we got the cross out your 7 next to it and turn that into a 6 then change 2 into 12 and then do 12 - 4 equals 8 then since you changed your 7
into a 6 6-3 would you get three and then you do 2-0 because there is no number there and you put down 23823 so 23823 is your answer
Yes that is the answer 19
Answer:
option C
15 14
-1 9
Step-by-step explanation:
Given in the question a 2x3 and 3x2 matrix
Since, the column of first matrix and row of second matrix is of equal integer, 3, so we can multiply them.
The resultant matrix will be of 2x2
We will use dot product
1(2) + 3(3) + 1(4) 1(-2) + 3(5) + 1(1)
-2(2) + 1(3) + 0(4) -2(-2) + 1(5) + 0(1)
