Given information
-----------------------------------------------
First showing : 1.30pm
Second showing : 4.15 pm
Inbetween : 1/2 hour break
-----------------------------------------------
Find the time the first showing ends
-----------------------------------------------
1/2 hours before 4.15pm
⇒ 30 mins before 4.15pm
⇒ 3.45pm
-----------------------------------------------
Calculate the duration of the firs show
-----------------------------------------------
1.30pm to 3.30pm = 2 hours
3.30pm to 3.45pm = 15 mins
Total duration = 2 hours 15 mins
-----------------------------------------------
Answer: 2 hours 15 mins

Answer:
30
Step-by-step explanation:
To find the determinant of a 3x3 matrix, you can use this method. (See picture.)
Start with the first number in the top row, and block off the row and column. A 2x2 matrix will be left. Find the determinant of this 2x2 matrix, and multiply it by the number in the top row.
Repeat for the other two numbers in the top row. Add the first result, subtract the second, and add the third.
det A = -2 [(3)(-5) − (a)(0)] − 2 [(0)(-5) − (a)(0)] + b [(0)(0) − (3)(0)]
det A = -2 (3)(-5) − 0 + 0
det A = 30
Answer:
25
Step-by-step explanation:
4x = 100
x = 100/4
x = 25
Answer:
46
Step-by-step explanation:
Let number is x greater than 21 and x less than 71.
Now, according to question,
21+x=71−x
2x=50
x=25
So, required number is 21+x=21+25=46.
Alternatively,
The required number would be the average or mean of 21 and 71.
So, required number =
2
(21+71)
=46.
