The 40-hour work week did not become a U.S. standard until 1940.

x = -1/4, y = -1/2
Step by step.
(A) 2x + 3y + 2 = 0
(B) 2x + y = -1
I like to label my equations first, A and B.
I will change (B) into y intercept form for ease of doing the math.
(A) 2x + 3y + 2 = 0
(B) y = -2x -1
Now we will solve by substituting the y value of B into the y spot in the A equation.
2x + 3(-2x -1) + 2 = 0
Distribute parenthesis first
2x -6x -3 +2 = 0
Combine terms
-4x -1 = 0
Now we want to isolate x on one side of = by adding 1 to both sides
-4x -1 +1 = 0 +1
-4x = 1
Now solve for x
Divide both sides by -4
-4/-4 x = 1/-4
X = -1/4
Now to solve for y, substitute your x value into equation B
y = -2x -1
y = (-2)(-1/4) -1
y = 1/2 -1
y = -1/2
We can check our work by substituting our x and y values into equation B
y = -2x -1
-1/2 = -2(-1/4) -1
-1/2 = 1/2 -1
-1/2 = -1/2

Annika sells 6-inch pies for $5.00 and 8-inch pies for $9.00 each. Last week she sold twice as many 6 inch pies as she did 8-inch pies. She made $133.00 from her sales. Annika defined x as the number of 6 inch pies she sold and y as the number of 8-inch pies she sold. She wrote the system below.
6 x + 8 y = 133. 2 x = y.
Which statements about the system are true? Check all that apply.
1. Since the cost for each pie is $5 and $9, the first equation should be 5 x + 9 y = 133.
2. Since the 8-inch pies are 2 inches larger, the second equation should be x + 2 = y.
Since there are fewer 8-inch pies, the second equation should be x = 2 y to balance the values.
3. The first equation is correct because 6x represents the money earned for 6-inch pies and 8y represents the money earned for 8-inch pies.

Answer: Voluntary Response
Step-by-step explanation:

And we're asked to evaluate whether this is
A) Statistic
B) Random Sampling
C) Voluntary Response
A statistic is "any quantity computed from values in a sample which is considered for a statistical purpose."
Random sampling is "a method of data collection and analysis designed to select a representative sample of respondents out of a larger population."
Finally, we have voluntary response which is "a deliberately chosen reaction to a stimulus that may require a complex coordination of excitatory and inhibitory impulses with feedback from visual, motor, and other systems."
Out of all of the following definitions, voluntary response is what fits this scenario best. Voluntary response usually includes the response of people with very strong opinions, and recalling how Mrs. Finn reacted to her hotel, I'd say it fits.

To calculate the value of the account on January 1, 2021, we need to consider the compounding interest for each year.
First, we calculate the value of the initial deposit after three years (12 quarters) using the formula for compound interest:
Principal = $1,000
Rate of interest per period = 8% / 4 = 2% per quarter
Number of periods = 12 quarters
Value after three years = Principal * (1 + Rate of interest per period)^(Number of periods)
= $1,000 * (1 + 0.02)^12
≈ $1,166.41
Next, we calculate the value of the additional $1,000 deposit made on January 1, 2019, after two years (8 quarters):
Principal = $1,000
Rate of interest per period = 2% per quarter
Number of periods = 8 quarters
Value after two years = Principal * (1 + Rate of interest per period)^(Number of periods)
= $1,000 * (1 + 0.02)^8
≈ $1,165.16
Finally, we add the two values to find the total value of the account on January 1, 2021:
Total value = Value after three years + Value after two years
≈ $1,166.41 + $1,165.16
≈ $2,331.57
Therefore, the value of the account on January 1, 2021, is approximately $2,331.57.

A sporting goods manufacturer requires 5/6 yd of fabric to make a pair of soccer shorts. How many shorts can be made from 35 yds of fabric?
Answers
Answer:
\(42\)
Step-by-step explanation:
Another way to look at this question is: We make 5/6 yards of fabric from each pair of shorts. How many shorts do we need to make 35 yards of fabric.
So, we need to solve this equation for \(x\): \(x*5/6=35\).
We can multiply both sides of the equation by \(6\) to get \(x*5=210\).
We then divide by \(5\) on both sides to get \(x=42\).
So, we can make \(\boxed{42}\) pairs of soccer shorts.

According to the given definition, if f(x) is a polynomial function, we can obtain f(A) by replacing x with the matrix A in the polynomial expression.

area of shape = 112in
Answer:
The area of the figure is 112
Step-by-step explanation:
For area, you multiply length x width
For the triangle, you do HALF THE BASE x height
So for the square, it's fairly simple
10 x 10 = 100
For the triangle, it's a bit more complicated
So we know the length of the square is 10 inches
And we see a 6 inch mark at the top of the square, showing where the square ends and the triangle begins
So the base of the triangle is 10 - 6 = 4 inches
Also, the overall height of the figure is 16 inches, and the height of the square is 10 inches
So the height of the triangle is 16 - 10 = 6 inches
So 4 is the base of the triangle
And 6 is the height of the triangle
So we half 4, which gives us 2
2 x 6 = 12
The area of the triangle is 12
And we already determined that the area of the square is 100
100 + 12 = 112
The area of the whole figure is 112

10 cups

20 balloons
Since the cost of cups, plates, and balloons is written as 100 of them, we just have to divide each of the by the amount we got after dividing by 10 and use that same amount and divide the money...
1. 10 cups is 1/10 of 100 cups so we divide $5.45 by 10 = .545
2. 10 plates is 1/10 of 100 plates so we divide $4.75 by 10 = .475
3. 20 balloons is 1/5 of 100 balloons so we divide $7.80 by 5 = 1.56

The population of a city is P(t)=9e "
P(t)=9 e^{0.05 t} (in millions), where t is measured in years. (a) Calculate the doubling time of the population. (b) How long does it take for the population to triple in size? (c) How long does it take for the population to quadruple in size? (a) (b) (c)
Answers
(a) The doubling time of the population is approximately 13.86 years., (b) It takes approximately 23.10 years for the population to triple in size, (c) It takes approximately 27.72 years for the population to quadruple in size.
To calculate the doubling time of the population, we need to find the time it takes for the population to double from its initial value. In this case, the initial population is 9 million.
(a) Doubling Time:
Let's set up an equation to find the doubling time. We know that when the population doubles, it will be 2 times the initial population.
2P(0) = P(t)
Substituting P(t) = 9e^(0.05t), we have:
2 * 9 = 9e^(0.05t)
Dividing both sides by 9:
2 = e^(0.05t)
To solve for t, we take the natural logarithm (ln) of both sides:
ln(2) = 0.05t
Now, we can isolate t by dividing both sides by 0.05:
t = ln(2) / 0.05
Using a calculator, we find:
t ≈ 13.86
Therefore, the doubling time of the population is approximately 13.86 years.
(b) Time to Triple the Population:
Similar to the doubling time, we need to find the time it takes for the population to triple from its initial value.
3P(0) = P(t)
3 * 9 = 9e^(0.05t)
Dividing both sides by 9:
3 = e^(0.05t)
Taking the natural logarithm of both sides:
ln(3) = 0.05t
Isolating t:
t = ln(3) / 0.05
Using a calculator, we find:
t ≈ 23.10
Therefore, it takes approximately 23.10 years for the population to triple in size.
(c) Time to Quadruple the Population:
Similarly, we need to find the time it takes for the population to quadruple from its initial value.
4P(0) = P(t)
4 * 9 = 9e^(0.05t)
Dividing both sides by 9:
4 = e^(0.05t)
Taking the natural logarithm of both sides:
ln(4) = 0.05t
Isolating t:
t = ln(4) / 0.05
Using a calculator, we find:
t ≈ 27.72
Therefore, it takes approximately 27.72 years for the population to quadruple in size.
