Answer:
0.27 lt/s
Step-by-step explanation:
80 liters in 5 minutes
5 minutes are 300 seconds (5x60)
We know how many seconds we need to fill up the tank (300 seconds for 80 liters). Now we need to know how many liters we can fill up in 1 second, as the question requires "liters per second".
80 lt / 300 sec
X lt / 1 sec
80 x 1
---------- = X
300
X = 0.2666666...
X = 0.27 lt / s
Answer:
The percent attendance for that semester was 30%.
Step-by-step explanation:
In this problem, out of 190 students, only 57 students had perfect attendance. When a question says something like this, then it means that you are going to use division. You are going to divide 57 by 190.
57 ÷ 190 = 0.3
Now, multiply 0.3 by 100 to get the percentage.
0.3 * 100 = 30
So, the percentage of the perfect attendance is 30%.

Answer:
Expand the brackets, and simplify.
(4t - 8/5)-(3-4/3t) = (4t +4/3t) + ( -8/5 - 3) = 5 1/3t - 23/5 = 16/3t - 23/5
5(2t + 1) + (-7t + 28) = 10t + 5 - 7t + 28 = 3t + 33
(-9/2t + 3) + (7/4t + 33) = (-9/2t + 7/4t) + (3 + 33) = -11/4t + 36
3(3t - 4) - (2t + 10) = 9t - 12 - 2t - 10 = 7t - 22
