The best and most correct answer among the choices provided by your question is the second choice or letter B "20".
The current area is 120(80)=9600 and he want to expand it by 4400 so that the new area will be 9600+4400=14000
14000=(120+x)(80+x)
14000=9600+200x+x^2
x^2+200x-4400=0
x^2-20x+220x-4400=0
x(x-20)+220(x-20)=0
(x+220)(x-20)=0, since x is an increase it must be greater than zero so
x=20ft
(120+20)(80+20)=14000ft^2

Answer:
Cost of child movie = x = $8
Cost of adult movie = y = $10.25
Step-by-step explanation:
Let cost of child movie = x
Cost of adult movie = y
Now converting statements into mathematical expressions:
Hansen family bought 2 child and 2 adult movie tickets and paid $36.50.
Owens family bought 5 child and 2 adult tickets and paid $60.50.
Let:
Subtract both equations:
So, we get Value of x =8
Now, putting value of x in eq(1) to find value of y
So, we get Value of y = 10.25
So,
Cost of child movie = x = $8
Cost of adult movie = y = $10.25
Answer:
The correct option based on the below computation of Sharpe ratio for all funds is option C,Fund C.
Step-by-step explanation:
Sharpe ratio=(Average return of the fund-risk free rate of return)/standard deviation of the fund
Risk free rate of return is 6%
Fund A:
Sharpe ratio=(24%-6%)/30%=0.6
Fund B:
Sharpe ratio=(12%-6%)/10%=0.6
Fund C:
Sharpe ratio=(22%-6%)/20%=0.8
Fund has a sharpe ratio of 0.8 ,unlike funds A& B that have a ratio of 0.6 each
In other words option C is correct

Answer:
5x and 6x both have the letter x. Let's combine them! 5x+6x = 11x
y, y, and 3y all have the letter y. You can imagine y to be 1y, they're the same.
1y + 1y + 3y = 5y
4, 6, and 2 don't have any letters. 4 + 6 + 2 = 12
Now you have to put all the final terms together to get: 11x + 5y +12
