Uh I don’t think so.
Sorry! But stay safe! :)
-- The filler pipe can fill 1/6 of the pool every hour.
-- The drainer pipe can drain 1/10 of the pool every hour.
-- When they're filling and draining at the same time, the filler pipe
will win eventually, because it finishes more of the pool in an hour
than what the drain pipe can finish in an hour.
-- When they're filling and draining at the same time, then every hour,
1/6 of the pool fills and 1/10 of it empties. The difference is (1/6) - (1/10).
To do that subtraction, we need a common denominator.
The smallest denominator that works is 30.
1/6 = 5/30
1/10 = 3/30 .
So in every hour, 5/30 of the pool fills, and 3/30 of the pool empties.
The result of both at the same time is that 2/30 = 1/15 fills each hour.
If nobody notices what's going on and closes the drain pipe, it will take
<em><u>15 hours</u></em> to fill the pool.
If the drain pipe had <em><u>not</u></em> been open, the filler pipe alone could have filled
the pool <em><u>2-1/2 times</u></em> in that same 15 hours. With both pipes open,
1-1/2 pool's worth of water went straight down the drain during that time,
and it was wasted.
I would say that the school should take the cost of 1-1/2 poolsworth out
of Ms. Charles' pay at the rate of $5 a week. I would, but that would
guarantee her more job security than she deserves after pulling a stunt
like that.
I hope this did not take place in California.
The width would be 90.
900/100=90
Since it give you the over all square yards, you take that number and divide it by what ever the number would be and that gives you the answer.
<h2>9</h2>
To find the median the first thing we need to do is organize the numbers from smallest to largest:
6 7 8 8 9 10 13 14 15
Then if the amount of numbers is odd, the median is the number which is in the middle. In this case the middle number is 9.
6 7 8 8 9 10 13 14 15
Hope this helps mate! Best of luck to you. :)
To do this, we must set up ratios:
Option One:
The first options costs only
$0.0092/gram (a fraction of a penny)!
Option Two:
The second option costs only
$0.0085/gram (cheaper than option one)!
Option Three: This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore,
1,000g costs $5.65. Next, we set up the ratio as usual:
The third option costs
$0.00565/gram.
Therefore,
option three is the cheapest! Hope this helps!
