Answer:
Interest = $93.205
Explanation:
Interest can be calculated as follows:
I = Prt
where:
I is the interest we want to canlculate
P is the principle amount = $1400
r is the interest rate in decimal = 9% = 0.09
t is the time in years = 270/365
Substitute with the givens in the above equation to get the value of the interest as follows:
I = 1400 * 0.09 * (270/365)
I = $93.205
Hope this helps :)

Answer:
The 
of the clean compound is approximately 10.495.
Step-by-step explanation:
If the cleaning ion concentration of the cleaning compound is ![[H^{+}] = 3.2\times 10^{-11}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%20%3D%203.2%5Ctimes%2010%5E%7B-11%7D)
, then the , no unit, of the compound is:
![pH = -\log_{10} [H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-%5Clog_%7B10%7D%20%5BH%5E%7B%2B%7D%5D)
(1)
The of the clean compound is approximately 10.495.
The answer is :
0.18181818

Answer:
at least 4674 flags should be sold to show a profit
Step-by-step explanation:
The net profit is defined as the revenue (income from selling the flags) minus the cost (of producing the flags).
Since we want that profit (P) to be larger than zero, we want the Revenue (R) to be larger than the cost (C):
P = R - C
we want P > 0 (zero) then we want: R - C > 0 which means R > C
We can now replace R and C by their expressions in terms of x (the number of flags produced):
36 x > 32 x + 18695
we subtract 32 x from both sides to gather all terms in the variable "x" on the left hand side of the equation:
36 x - 32 x > 18695
4 x > 18695
Now we solve for x by dividing both sides by 4 (thus isolating the unknown x):
x > 18695 / 4
x > 4673.75
Therefore x must be at least the following integer to 4673.75, that is : 4674
