Answer: The answers are given below.
Step-by-step explanation: Given in the question that Kent invested $5000 in a retirement plan. He allocated x dollars of the money to a bond account that earns 4% interest per year and the rest to a traditional account that earns 5% interest per year.
(A) Let, '$y' be the amount of money Kent invested in the traditional account, then we have
![y=5000-x.](https://tex.z-dn.net/?f=y%3D5000-x.)
This is the required expression.
(B) After 1 year, total money in the bond account will be
![M_b=x+\dfrac{1\times 4\times x}{100}=x+\dfrac{x}{25}=\dfrac{26}{25}x,](https://tex.z-dn.net/?f=M_b%3Dx%2B%5Cdfrac%7B1%5Ctimes%204%5Ctimes%20x%7D%7B100%7D%3Dx%2B%5Cdfrac%7Bx%7D%7B25%7D%3D%5Cdfrac%7B26%7D%7B25%7Dx%2C)
and amount of money in the traditional account will be
![M_t=(5000-x)+\dfrac{1\times 5\times (5000-x)}{1000}=(5000-x)+\dfrac{5000-x}{200}\\\\\\\Rightarrow M_t=\dfrac{201(5000-x)}{200}.](https://tex.z-dn.net/?f=M_t%3D%285000-x%29%2B%5Cdfrac%7B1%5Ctimes%205%5Ctimes%20%285000-x%29%7D%7B1000%7D%3D%285000-x%29%2B%5Cdfrac%7B5000-x%7D%7B200%7D%5C%5C%5C%5C%5C%5C%5CRightarrow%20M_t%3D%5Cdfrac%7B201%285000-x%29%7D%7B200%7D.)
Therefore, total amount invested after 1 year will be
![M=M_b+M_t=\dfrac{26}{25}x+\dfrac{201(5000-x)}{200}=\dfrac{208x+1005000-201x}{200}\\\\\\\Rightarrow M=\dfrac{7x+1005000}{200}.](https://tex.z-dn.net/?f=M%3DM_b%2BM_t%3D%5Cdfrac%7B26%7D%7B25%7Dx%2B%5Cdfrac%7B201%285000-x%29%7D%7B200%7D%3D%5Cdfrac%7B208x%2B1005000-201x%7D%7B200%7D%5C%5C%5C%5C%5C%5C%5CRightarrow%20M%3D%5Cdfrac%7B7x%2B1005000%7D%7B200%7D.)
(C) If x = $500, then we have
![M=\dfrac{7\times 500+1005000}{200}=\dfrac{1008500}{200}=\dfrac{10085}{2}=5042.5.](https://tex.z-dn.net/?f=M%3D%5Cdfrac%7B7%5Ctimes%20500%2B1005000%7D%7B200%7D%3D%5Cdfrac%7B1008500%7D%7B200%7D%3D%5Cdfrac%7B10085%7D%7B2%7D%3D5042.5.)
Thus, Kent will have $5042.5 in his retirement plan after 1 year.

not me srry
Step-by-step explanation:
Initial volume of water = 20 litres
Final volume of water = 14 litres
Leaked volume of water = 6 litres

Answer: ![126^{\circ}](https://tex.z-dn.net/?f=126%5E%7B%5Ccirc%7D)
Step-by-step explanation:
If we draw RP and PS, then in the quadrilateral formed, we know that
, and since angles in a quadrilateral add to 360 degrees, this means
.
Thus, arc RS also measures 126 degrees
