16. Calculate the GDP using value-added approach. Explain how you got your answer.
The GDP using value added approach is $3.50
How to calculate the GDP?GDP using value added approach is calculated by obtaining the sum total of value added by each production unit.
Value added by Farmer Fred = Price of output - Cost of inputs = $0.50 - $0 = $0.50
Value added by Baker Bob = Price of output - Cost of inputs = $1.50 - $0.50 = $1.00
Value added by Trucker Tom = Price of output - Cost of inputs = $2.25 - $1.50 = $0.75
Value added by Retail Rob = Price of output - Cost of inputs = $3.50 - $2.25 = $1.25
GDP = Value added by Farmer Fred + Value added by Baker Bob + Value added by Trucker Tom + Value Added by Retail Rob
GDP = $0.50 + $1.00 + $0.75 + $1.25

The size of angle x = 46 degree.
Now, According to the question:
A triangle in which at least two sides are equal is called an isosceles triangle. Following this fact, if two sides of a triangle are equal, then the angles opposite to those sides are also equal.
"Information available from the question"
Since Δ ABC is equilateral then interior angles = 60°
Since CE = DE then Δ CDE is isosceles and the base angles are congruent,
So,
∠ ECD = [tex]\frac{180-32}{2}[/tex] = [tex]\frac{148}{2}[/tex] = 74 degree
BCD is a straight line, then the 3 angles on it sum to 180°, that is
60° + 74° + x = 180°
134° + x = 180° ( subtract 134° from both sides )

What is the total area of the land and walkway combined?We know that for a circle of radius R, the area is:
A = pi*R²
Where pi = 3.14
In this case we have a circular plot of land with a diameter of 6ft, then the radius (half of that) is:
R = 6ft/2 = 3ft
And then we have a walkway with a width of 2x, then the radius of the circle that includes the walkway is:

The graph represents the function f(x). Which set of points lie on its inverse f^-1(x)?
Answer:
Third choice: (1, -3); (2, 2); (3, 7)
Step-by-step explanation:
There are two ways to solve this
The easiest way to solve this is to understand that the inverse of a function f(x), denoted by f⁻¹(x) is nothing but a reflection of the function about the line y = x
What that means is that if (x, y) is a specific point on the line, then the inverse point will be (y, x). Basically we are swapping the x, y values
The 3 points on f(x) and the corresponding points on f⁻¹(x) are given below:
f(x) f⁻¹(x)

solve these proportion for the variable x. Use the reasoning of scalling to solve
The value of x from the given proportion is given as x = 10 after scalling both side of the equation.
What is Ratio and Proportion ?A ratio is a divisional comparison of two quantities, and a proportion is the equality of two ratios. A ratio is often read as "x is to y" but may also be written as "x: y" or "x/y." The proportion equation, on the other hand, states that two ratios are equal.
The equality of two ratios is referred to as proportion. There is never a difference between two comparable ratios. The ratio sign (::) is used to express proportions, which aid in solving problems with ambiguous amounts. To put it another way, a percentage is an equation or a claim that shows the equality of two ratios or fractions. If a: b = c: d, then four non-zero values, a, b, c, are said to be in proportion. Let's now compare the two ratios, 3:5 and 15:25. In this case, 3:5 and 15:25 may both be written as 3:5 = 3/5 and 0.6, respectively. We may argue that these two ratios are proportionate because they are both equal.

If I take a loan of 4500€ at 6.5% and pay it back in 4 years, how much interest will i pay?
The required simple interest would be the amount of 1,170€ on a 4500€ principal deposited for four years at a rate of 6.5%
We have been given data as:
Principal (P) = 4500€
Rate of Interest (R) = 6.5% = 6.5/100 = 0.065
Time (T) = 4 years
⇒ Simple interest = P × R × T
Substitute the value of P, R, and T in the above formula,
⇒ Simple interest = 4500 × 6.5% × 4
⇒ Simple interest = 4500 × 6.5/100 × 4
⇒ Simple interest = 4500 × 0.065 × 4
Apply the multiplication operation, and we get
⇒ Simple interest = 1,170€
Therefore, the required simple interest would be the amount of 1,170€.

On a team, 3 girls and 2 boys scored a total of 27 points. The difference between the number of points scored by the 3 girls and the number of points scored by the 2 boys is 15. Each girl scored the same number of points, and each boy scored the same number of points. Find the number of points scored by each girl and each boy.
Answer: Let x be the number of points scored by each girl and y be the number of points scored by each boy.
We know that:
3x + 2y = 27 (the total number of points scored by the 3 girls and 2 boys)
3x - 2y = 15 (the difference between the number of points scored by the girls and the number of points scored by the boys)
We can use the second equation to find the value of one of the variables and substitute it into the first equation.
3x - 2y = 15
3x = 15 + 2y
Substitute this into the first equation:
(15 + 2y) + 2y = 27
2y = 12
y = 6
Now that we know that each boy scored 6 points, we can substitute that back into the second equation to find the number of points each girl scored:
3x - 2y = 15
3x - 2(6) = 15
3x = 27
x = 9
So each girl scored 9 points and each boy scored 6 points.
Step-by-step explanation:
On a team have 3 girls and 2 boys
Let say each girl points scored=x
Let say each boy points scored=y
Total scored by 3 girls and 2 boys =27
3x +2y=27----------1
The difference between points of 3 girls and 2 boys =15

The area of the border is 72 square inches - 80 square inches = -8 square inches.
What is rectangle ?
A rectangle is a four-sided geometric shape with four right angles. The opposite sides of a rectangle are of equal length and parallel to each other, and the opposite angles are equal. The length and width of a rectangle are its two dimensions, with the length being the longer side and the width being the shorter side.
To find the area of the border, subtract the area of the photograph from the total area of the photograph and the frame. The total area of the photograph and the frame is the area of the frame (which is just the border) plus the area of the photograph.
The area of the photograph is 8 inches * 10 inches = 80 square inches
The area of the frame is the perimeter of the photograph (28 + 210) multiplied by the width of the border, which is 2 inches. So the area of the frame is 2*(28 + 210) = 2*36 = 72 square inches.
Therefore, the area of the border is 72 square inches - 80 square inches = -8 square inches.

2. The result of this calculation is the cost of each wing ($15 / 18 = $0.83).
3. Divide 1 by the cost of each wing ($1 / $0.83 = 1.2 wings per dollar).
The cost of 18 wings is $15. To calculate the cost of the wings per dollar, divide the total cost of the wings ($15) by the number of wings (18). This calculation will give the cost of each wing ($15 / 18 = $0.83). To find the number of wings per dollar, divide 1 by the cost of each wing ($1 / $0.83 = 1.2 wings per dollar). This means that for every dollar spent, 1.2 wings can be purchased.

use the given frequency distribution to find the (a) class width. (b) class midpoints of the first class. (c) class boundaries of the first class.
(a)The class width = 3
(b) The class midpoint of the first class = 51
(c) The class boundaries of the first class = (49.5, 52.5)
Consider the frequency distribution in the following image.
We know that in frequency distribution the class width is nothing but the distance between the lower limits of consecutive classes.
Whereas the range is the difference between the maximum and minimum data entries.
The smallest number is 50, and the largest is 62.
So the range is 62 - 50 = 12
We know that the formula for the class width:
Class width= upper limit – lower limit +1
So, the class width = 52 - 50 + 1
= 3
The formula for the midpoint of each class:
midpoint = (lower limit of class + upper limit of class)/2
Let us assume that m be the midpoint of the first class.
Using above formula of midpoint:
m = (50 + 52)/2
m = 51
We know that the class boundaries are nothing but the end points of an open interval which contains the class interval.
So, the class boundaries of the first class = (49.5, 52.5)
