Answer:
water : 90 ounces
salt solution: 90 ounces
Step-by-step explanation:
Call w the amount of water and call the solution containing 30% salt.
We want to get 180 ounces of a mixture with 15% salt.
So:
The amount of mixture will be:

the amount of salt will be



Now we substitute the value of s in the first equation and solve for w


Given that <span>the average volume of water that flows over the falls each second is

gallons.
There are 3,600 seconds in one hour.
Thus, in one hour,

gallons of water </span><span>flows over the falls.
</span>Therefore, the amount of water that flows over the falls is <span>

Answer:
$1950
Step-by-step explanation:
Simple interest amount payable is given by
A=P(1+rt) where p is principal amount, A is final amount paid, t is time and r is rate of interest. For the first case
A=15000(1+0.03*4)=$16800
For second case
A=15000(1+0.05*5)=$18750
Difference will be 18750-16800=$1950
Well to find the value of the interior angle of a hexagon it would be out of a total of 720 degrees therefore just subtract the values of the known interior angle values and you should be able to get the value of the interior angle of X
