The plumber's 2 hour and 26 min plumbing bill cost is $73
What is the plumber's per minute rate?
The plumber's per minute rate is the per half-hour rate divided by 30 minutes since the plumber charges $15 for every 30-minute job
per-minute rate=$15/30
per-minute rate=$0.50
Now, let us convert 2hours and 26 minutes to minutes, in other words, every 1 hour is 60 minutes, the two hours equal 120 minutes plus the 26 minutes gives a total of 146 minutes
Total minutes=120 min+26 min
total minutes=146 minutes
Total plumbing bill cost for 146 minutes is $0.50, the per-minute rate multiplied by the number of minutes the plumber needs to work in this case
2 hour and 26 min plumbing bill cost=146*$0.50
2 hour and 26 min plumbing bill cost=$73

Point <em>A</em> represents the complex conjugate z₁ and point L represents the complex conjugate of z₂ respectively
The complex conjugate of a complex number is a complex number that having equal magnitude in the real and imaginary part as the complex number to which it is a conjugate, but the imaginary part of the complex conjugate has an opposite sign to the original complex number
Therefore, graphically, the complex conjugate is a reflection of the original complex number across the x-axis because the transformation for a reflection of the point (x, y) across the x-axis is given as follows;
Preimage (x, y) reflected across the <em>x</em> axis give the image (x, -y)
Where in a complex number, we have;
x = The real part
y = The imaginary part
The reflection of z₁ across the x-axis gives the point <em>A</em>, while the reflection of z₂ across the x-axis gives the point <em>L</em>
Therefore;
Point <em>A</em> represents the complex conjugate z₁ and point L represents the complex conjugate of z₂

Answer:
Step-by-step explanation:
Multiplication
Ratio of Tables to garbage = 8:3
Small camp ground:
40 picnic tables and let x be the number of garbage cans
x = 15
Small campground with 40 picnic table needs 15 garbage cans
Large picnic ground:
120 picnic tables and let y be the number of garbage cans
y= 45
Big campground with 120 picnic table needs 45 garbage cans
