The square root of 13 is approximately 3.60555127546. When rounded to the nearest tenth, this value becomes 3.6.
To find the nearest tenth of the square root of 13, you first need to calculate the square root of 13 using a calculator. The calculator will show that the square root of 13 is approximately 3.60555127546.
To round this to the nearest tenth, look at the second digit after the decimal point which is 0. If this number is 5 or larger, we round up the first digit after the decimal point, if not, we keep it as it is. In this case, the value of the second digit after the decimal point is 0, which is less than 5. Therefore, the square root of 13 rounded to the nearest tenth is 3.6.

B) 10 gallons of the 12% and 10 gallons of the 7%
C) 8 gallons of the 12% and 12 gallons of the 7%
D) 2 gallons of the 12% ad 18 gallons of the 7%
Answer: 12 gallon of 12% sugar and 8 gallon of 7% sugar.
Step-by-step explanation:
Let we use x gallon of 12% of sugar mixture and y gallon of 7% of sugar mixture.
Thus, According to the question,
The resultant mixture having quantity 20 gallon,
Therefore, x + y = 20 ------(1)
Also, Sugar in x gallon mixture + sugar in y gallon mixture = sugar in resultant mixture.
Again according to the question,
Resultant mixture has 10% of sugar.
Therefore, 12% of sugar in x gallon + 7% sugar in y gallon = 10% sugar in 20 gallon
0.12 x + 0.07 y = 0.2
12 x + 7 y = 200 --------(2)
7× equation (1),
We get, 7x + 7y = 140 -----(3)
Equation(1) - equation (3)
5 x = 60
x = 12
By putting the value of x in equation (1),
12 + y = 20
⇒ y = 8
Thus, He will add 12 gallon of 12% sugar mixture and 8 gallon of 7% sugar mixture for obtaining 20 gallon of 10% sugar mixture.
Therefore, First Option is correct.

B. Use the model created in part A to create a graph representing Jeanne’s probable income earned and possible number of hours worked this week.
C. Analyze the set of coordinate values that represent solutions for the model created in part A. Choose one of the coordinates within the solution and algebraically prove that the coordinate represents a true solution for the model.
Answer:
x+y≤20
6x+10y ≥ 75
Step-by-step explanation:
Let the number of hours of babysitting be x and that for tutoring be y
As per the given conditions
The total no of hours of work must be less than or equal to 20
Hence
x+y≤20
Also Her target is to earn atleast $75
Hence the second inequation will be
6x+10y≥75
Hence our system of inequatlites representing above conditions are
x+y≤20
6x+10y≥75
Now in order to graph them , we first graph the lines x+y=20 and 6x+10y=75 and shade the region which satisfies the respective inequality by taking a coordinate (0,0) .
Please refer to the graph attached with this.
The shaded region gives us the set of coordinates probably the solution to above inequations.
Let us pick one coordinate (10,5) from the shaded region and check for the solution.
put (10,5) in two inequations and see if they are true for them.
10+5≤20
15≤20 True
6(10)+10(5) ≥75
60+50≥75
110≥75 true
Hence checked , both stands true for (10,5)
Answer:
The total assets of Aaron is $1026 .
Step-by-step explanation:
As given in the question
Aaron has a total net worth of $456. If his liabilities are $570 .
Thus
Assets = Liabilities value + Total net worth value
Put all the values in the above
= $570 + $456
= $ 1026
Therefore the total assets of Aaron is $1026 .
