The consumer price index (CPI) is a measure of the average change of prices paid by urban consumers for goods and services. If a worker earned $28.50 per hour in the year 2000, how much would he need to earn in 2004 to have the same buying power as he did in 2000?
Answer:
$31.37 per hour
Step-by-step explanation:
In order to calculate how much he needs to earn to have the same buying power we first need to know how much inflation occurred over those years. According to data from the consumer price index charts, these years had the following inflation rates.
2000 = 3.4%2001 = 2.8%2002 = 1.6%2003 = 2.3%Total = 3.4 + 2.8 + 1.6 + 2.3 = 10.1%We don't include 2004 because inflation rates are calculated when the year is over and the individual is currently in 2004 in this scenario. Now we multiply the total inflation rate to the amount that the individual was making in the year 2000. But we turn the percentage into a decimal and add 1 to it so that we are increasing the wage.
(10.1 / 100) + 1 = 1.101
28.50 * 1.101 = $31.37
Therefore, the individual needs to have a wage of $31.37 per hour to maintain the same buying power in 2004 as in 2000.

======================================================
Explanation:
Focus on triangle ABC. Let's find the missing angle
A+B+C = 180
113+B+22 = 180
B+135 = 180
B = 180-135
B = 45
Between the triangles, have two pairs of angles that are congruent
A = D = 113
B = E = 45
Which is enough to prove the triangles are similar through the angle angle (AA) similarity theorem. This must mean that C = F = 22
Since we have A pair with D, and B pair with E, this means that [tex]\triangle ABC \sim \triangle DE F[/tex]
The order of the letters is important so we know how the angles pair up. The first letters pair up together, the second letters pair up, and so on.
Consequently, this means sides BC and EF pair up and AC and DF pair up
We can then say...
BC/EF = AC/DF
18/12 = x/4
18*4 = 12*x
72 = 12x
12x = 72
x = 72/12
x = 6
AC = 6
(14x – 13)
(4x + 13)
(6x + 2)
Answer:
x = 7.416666667
Step-by-step explanation:
Set everything equal to 180 (the total # of degrees in a triangle)
180 = 14x-13 + 4x+13 + 6x+2
Combine the variables
180 = 24x - 13 + 13 + 2
Do the math
180 = 24x +2
178 = 24x
x = 7.416666667
A variable is, to put it simply, a quantity that can be altered and is not fixed. If the variables be (14x – 13), (4x + 13) and (6x + 2) then the value of x exists 7.416666667.
What is meant by variables?An unknown numerical value in an equation or algebraic expression is represented by a symbol (typically a letter) in algebra. A variable is, to put it simply, a quantity that can be altered and is not fixed.
Let the variables be (14x – 13), (4x + 13) and (6x + 2).
Set all values to 180 (the sum of the triangle's degrees).
180 = (14x - 13) + (4x + 13) + (6x + 2)
180 = 14x - 13 + 4x + 13 + 6x + 2
simplifying the above equation, we get
180 = 24x - 13 + 13 + 2
180 = 24x +2
178 = 24x
Divide both sides of the equation by 24, we get
178/24 = 24x/24
x = 7.416666667
Therefore, the value of x = 7.416666667.

Y-5=1/2(x+2) what is the point and slope
Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 5 = [tex]\frac{1}{2}[/tex](x + 2) ← in point- slope form
with slope m = [tex]\frac{1}{2}[/tex] and (a, b) = (- 2, 5 ) ← point on line

Compare 4.10 and 12:20 using fractions. Which ratio is smaller? How do you know?
Answer: The answer is 4:10
Step-by-step explanation: Sample Response: First, I wrote each ratio as a fraction. Then I found a common denominator of 20. The fraction 4/10 is 8/20. Comparing numerators, 8 is less than 12, so the ratio 4:10 is smaller.

the answer is B and D
The equivalent expression are [tex]9^4[/tex] = 9 x 9 x 9 x 9, 9² x 9² and
[tex](9^{10}/9^8)^2[/tex]
What is Expression?Mathematical statements are called expressions if they have at least two terms that are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.
A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.
Given:
[tex]9^4[/tex]
So, if we expand the above expression using exponents and power
[tex]9^4[/tex] = 9 x 9 x 9 x 9
and, 9² x 9² = [tex]9^{2+2[/tex] = [tex]9^4[/tex]
Also, [tex](9^{10}/9^8)^2[/tex]
= (9²)²
= [tex]9^4[/tex]
Hence, the equivalent expression are [tex]9^4[/tex] = 9 x 9 x 9 x 9, 9² x 9² and
[tex](9^{10}/9^8)^2[/tex]
