The answer is 96 min, here is why:
x / 240 + x / 160 = 1
<span>2x + 3x = 480 </span>
<span>5x = 480 </span>
<span>x = 96 min
(</span><span>Drainage rate of first pipe = 480000/240 = 2000 l/min </span>
<span>Drainage rate of second tube = 480000/160 = 3000 l/min </span>
<span>Combined drainage rate = 5000 l/min </span>
<span>Time to drain = 480000/5000 = 96 min. )</span>
Answer: 36
Step-by-step: 6 2/3 + 5 1/3 = 12
12 x 3 = 36
The thousandths place in 275,608 is the 5. Depending on the next number (which in this case is the 6) it will either round up or down. Since the next number is 6 and it's 5 or bigger, the 5 will round up. So your final answer is 276,000.

Answer:
Step-by-step explanation:
Finding the vertex or the end of the shape.
Find the y -intercept, (0,f(0)) ( 0 , f ( 0 ) ) .
Solve f(x)=0 f ( x ) = 0 to find the x coordinates of the x -intercepts if they exist.
Make sure that you've got at least one point to either side of the vertex. ...
Sketch the graph.
