Answer:
n = [tex]\frac{-1}{2}[/tex] - [tex]\frac{3}{2}[/tex]m or n = -0.5 - 1.5m
Step-by-step explanation:
21m + 14n = -7 (subtract 21m from each side)
14n = -7 - 21m (divide everything by 14)
n = [tex]\frac{-7}{14}[/tex] - [tex]\frac{21}{14}[/tex]m
n = [tex]\frac{-1}{2}[/tex] - [tex]\frac{3}{2}[/tex]m or n = -0.5 - 1.5m

Productivity: My candy bar company made 100 million bars last year, sold for $1 each. I also paid [L] people last year, with an average salary of $100K last year. I have overhead cost of $10M. What was my TOTAL productivity (no units, rounded to 2 decimal places)?
Answer:
5
Step-by-step explanation:
Productivity: My candy bar company made 100 million bars last year, sold for $1 each. I also paid [L] people last year, with an average salary of $100K last year. I have overhead cost of $10M. What was my TOTAL productivity (no units, rounded to 2 decimal places)?
Solution:
Total productivity is the average of labour and capital productivity weighted and adjusted to price fluctuations. It is the ratio of total output to the total input. The total productivity is given by the formula:
Total productivity = total output / total input
Total output = Revenue = number of bars sold * price per bar
Total output = 100 million * $1 = $100 million
Total input = Total salary + overhead cost
Total salary = number of people * average salary = 100 *$100000 = $10 million
overhead cost = $10 million
Total input = $10 million + $10 million = $20 million
Total productivity = total output / total input = $100 million / $20 million
Total productivity = 5
yuh help please haha
Answer:
B
Step-by-step explanation:
Plug the coordinates in the answer choices to see if they give you 18.
Option A: 5(5) - 2(3) = 25- 6 = 9. Not it
Option B: 5(4) - 2(1) = 20 - 2 = 18. Works.
It has to be B because we've already tested (5,3) in option A and it wasn't correct.

Multiply by 23% or .23 then subtract what you get from that to the total of what she bought in all. There is your answer.
Calculating average speed:
1. A person walks 6.0 meters in a time of 2.0 seconds. What is the average speed. PLEASE HELP!!!
Answer:
3 meters per second.
Step-by-step explanation:
The formula for finding speed is: [tex]s = \frac{d}{t}[/tex]. D is distance. T is time. So in your case, you would divide 6.0 (distance) by 2.0 (time). Your answer is 3. Add meters per second because you divided meters/seconds.

For his long distance phone service, Ravi pays a $2 monthly fee plus 12¢ per minute. Last month, Ravi's long distance bill was $12.68. For how many minutes was Ravi billed?
Answer:
[tex]89\ \text{minutes}[/tex]
Step-by-step explanation:
Let the number of minutes Ravi spoke for be [tex]x[/tex]
The fixed monthly fee is $2
Per minute Ravi is charged 12¢ = $0.12
The charge in a month will be
[tex]y=2+0.12x[/tex]
In one month Ravi was billed $12.68. So [tex]y=12.68[/tex]
[tex]12.68=2+0.12x\\\Rightarrow x=\dfrac{12.68-2}{0.12}\\\Rightarrow x=89\ \text{minutes}[/tex]
So, Ravi spoke for [tex]89\ \text{minutes}[/tex] that month.

Graph the line that passes through the points (9,-8) and (9,6) and determine the
equation of the line.
Answer:
x = 9
Step-by-step explanation:
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the y intercept
Note that the line does not have a slope and the x intercept of the line is a point where the line cuts the x axis. Hence the equation of the line will be expressed as x = c where c is the x intercept;
From the graph, the x intercept =9. Hence the equation of the given line is x = 9

Answer:
24/7
Step-by-step explanation:
Answer:
The first one, 24/7
Step-by-step explanation:
The first thing that you would want to do is find the most common denominator which would be 21. then the fractions would be 72/21 and 70/21. In this case, 24/7 is bigger.

A baker decorates 61 cupcakes in 30 minutes. She decorates cupcakes at a constant rate. How many cupcakes can the baker decorate per minute?
Answer:
2.03 cupcakes per minute.
Step-by-step explanation:
The baker can decorate (61/30) cupcakes per minute, hence she can decorate 2.03 cupcakes per minute.
Hope this helped!
Answer:
The baker can decorate 2 cupcakes per minute
Step-by-step explanation:
The baker can decorate 2 cupcakes per minute and to find this you would divide 61 by 30 and you'd get 2.03333 repeating but you can't decorate three hundredths of a cupcake so you would round it to the nearest whole number to get 2 cupcakes per minute
What is the rectangular form of z= 40(cos(7pi/6)+ i sin(7pi/6))
a. z= 20-20i rt3
b. z= 20rt3 -20 i
c. z= -20rt3 -20 i
d. z= -20-20 i rt3
Answer:
C. [tex]z = -20\sqrt{3}-i\,20[/tex]
Step-by-step explanation:
The rectangular form of a complex number is represented by the following formula:
[tex]z = a+i\,b[/tex] (1)
Where each coefficient can be determined as function of the polar components:
[tex]a = r\cdot \cos \theta[/tex] (2)
[tex]b = r\cdot \sin \theta[/tex] (3)
Where:
[tex]r[/tex] - Magnitude of the complex number, dimensionless.
[tex]\theta[/tex] - Direction of the complex number, measured in radians.
If we know that [tex]r = 40[/tex] and [tex]\theta = \frac{7\pi}{6}[/tex], then the rectangular form of the number is:
[tex]a = 40\cdot \cos \frac{7\pi}{6}[/tex]
[tex]a = -20\sqrt{3}[/tex]
[tex]b = 40\cdot \sin \frac{7\pi}{6}[/tex]
[tex]b = -20[/tex]
The rectangular form of [tex]z=40\cdot\left(\cos \frac{7\pi}{6}+i\,\sin \frac{7\pi}{6}\right)[/tex] is [tex]z = -20\sqrt{3}-i\,20[/tex]. The correct answer is C.

Which functions are symmetric about the y-axis? Check all of the boxes that apply.
The functions that are symmetric about the y-axis are;
1) The function in the first option; f(θ) = cos(θ)
2) The function in the third option; f(x) = x²
Reason for the above selection;
Definition;
A function is symmetric about the y-axis is also known to be an even function such that the same value of the function is arrived at when x is replaced with -x
Analysis of the graphs;
First Function Graph; The graph represents the graph of cos (θ)
∴ The function is f(θ) = cos(θ)
The value of the function when x = π, f(π) = -1
Similarly, the value of the when x = -π, f(-π) = -1
f(π) = f(-π)
∴ f(x) = f(-x)
Therefore; the first function is an even function
Second Function Graph; The function of the graph is x = y²
∴ y = √(x)
The value of the function when x = 4, y = f(4) = 2
However, the when x = -4, f(-4) does not exist
f(4) ≠ f(-4)
∴ f(x) ≠ f(-x)
Therefore; the second function is not an even function (the function, x = y², is however symmetric about the x-axis)
Third Function Graph; The function the graph represents is y = x²
The value of the function when x = 2, f(2) = 4
Similarly, the value of the when x = -2, f(-2) = 4
f(2) = f(-2)
∴ f(x) = f(-x)
Therefore; the third function is an even function
From the above, the functions which are symmetric about the y-axis, (even functions) are;
The first and the third functions
