Answer:
5y=50
Step-by-step explanation:
3y - 8 = 22, right? So y would equal to 10 because 3x10 is 30 and 30 minus 8 is 22. Then you times 5 by 10 and get 50.

The population of Austin, Texas, is more than 790,390 people.
4. The digit 7 is in the hundred thousands
place and has a value of?
Answer:
700,000
Step-by-step explanation:
To explain this, we need to know the basics.
If you look at the number 790,390, you should automatically know that you can also write the same number as:
700,000 + 90,000 + 300 + 90
How did we do this?
Because each number in 790,390 has a value.
In fact, we can do this for any number! Like this:
12,345
You can also write the same number like this:
10,000 + 2,000 + 300 + 40 + 5
Back to the original question. If there is a seven in the hundred thousands place, that means that the 9 is equal to 700,000
Examples:
12,345
The 3 in this number stands for 300, since it is in the hundreds place.
678,900
The 7 in this number stands for 70,000 because it is in the ten thousands place

The area of a rectangle is found by multiplying the length and the width. The length is represented by x+8 and the width is represented by X+6. The total area is 288 in2. Solve for x in order to find the length and width of the rectangle. State the length and width of the rectangle. Show all of your work and use complete sentences in your answer.
Answer:
(-24 + 8) and (10 + 6)
Step-by-step explanation:
A = L x W
L = x + 8
W = x + 6
A = (x + 8)(x + 6)
288 = (x + 8)(x + 6)
x = 10
x = -24, 10

Answer:
Thor is the best deal.
Step-by-step explanation:
Thor is $10.35, Lemon is $11.73, Patrick is $14.66, and Sarah is $16.63.
For Thor, multiply $1.15(2)=$2.30. Then multiply $1.15(7)=$8.05. Add these together to get $10.35.
For Lemon, multiply 17($1.15)=$19.55. Then subtract by $7.82 to get $11.73.
For Patrick, use the equation we already did 17($1.15) and subtract $4.89 from it to get $14.66.
Last, For Sarah multiply our $19.55 (.15) to find 15% and get 2.934. Then subtract $19.56 - 2.934 to get $16.626. Round to $16.63.

Write an equation of the line shown. Then use the equation to find the value of x when y=112
Answer:
[tex] y = 8x + 16 [/tex]
[tex] x = 12 [/tex]
Step-by-step explanation:
Given two points on the line (0, 16) and (3, 40), an equation for the line can be written using the slope-intercept line equation which takes the format [tex] y = mx + b [/tex].
Where,
[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
b = y-intercept or the point at which the line cuts the y-axis.
Let's find slope (m) using the slope formula:
Let,
[tex] (0, 16) = (x_1, y_1) [/tex]
[tex] (3, 40) = (x_2, y_2) [/tex]
[tex] slope (m) = \frac{40 - 16}{3 - 0} [/tex]
[tex] slope (m) = \frac{24}{3} [/tex]
[tex] slope (m) = 8 [/tex]
Find b. Substitute the values of x = 0, y = 16, and m = 8 in the slope-intercept formula to find b.
[tex] y = mx + b [/tex]
[tex] 16 = 8(0) + b [/tex]
[tex] 16 = 0 + b [/tex]
[tex] 16 = b [/tex]
[tex] b = 16 [/tex]
Plug in the values of m and b into the slope-intercept formula to get the equation of the line.
[tex] y = mx + b [/tex]
[tex] y = 8x + 16 [/tex]
Let's use the equation to find x when y = 112.
[tex] y = 8x + 16 [/tex]
Substitute y = 112 in the equation
[tex] 112 = 8x + 16 [/tex]
[tex] 112 - 16 = 8x [/tex]
[tex] 96 = 8x [/tex]
Divide both sides by 8
[tex] 12 = x [/tex]
[tex] x = 12 [/tex]

Carbon 14 is a radioactive isotope of carbon, the most common isotope of carbon being carbon 12. Carbon 14 is created when cosmic ray bombardment changes nitrogen 14 to carbon 14 in the upper atmosphere. The resulting carbon 14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis. Animals acquire carbon 14 by eating plants. When an animal or plant dies, it ceases to take on carbon 14, and the amount of isotope in the organism begins to decay into the more common carbon 12. Carbon 14 has a very long half-life, about 5730 years. That is, given a sample of carbon 14, it will take 5730 years for half of the sample to decay to carbon 12. The long half-life is what makes carbon 14 dating very useful in dating objects from antiquity.
Consider a sample of material that contains A(t) atoms of carbon 14 at time t. During each unit of time a constant fraction of the radioactive atoms will spontaneously decay into another element or a different isotope of the same element. Thus, the sample behaves like a population with a constant death rate and a zero birth rate. Make use of the model of exponential growth to construct a differential equation that models radioactive decay for carbon 14.
Solve the equation that you proposed in to find an explicit formula for A(t).
Answer:
Differential equation: [tex]\frac{dA}{dt} = k\cdot A(t)[/tex], [tex]k < 0[/tex], [tex]k = -\frac{1}{\tau}[/tex], [tex]\tau > 0[/tex].
Solution: [tex]A(t) = A_{o}\cdot e^{-\frac{t}{\tau} }[/tex]
Step-by-step explanation:
Let suppose that rate of change of the amount of Carbon-14 atoms are directly proportional to the current amount of Carbon-14 atoms. That is:
[tex]\frac{dA}{dt}\propto A(t)[/tex]
[tex]\frac{dA}{dt} = k\cdot A(t)[/tex]
Where:
[tex]A (t)[/tex] - Amount of Carbon-14 atoms, dimensionless.
[tex]k[/tex] - Proportionality constant, measured in [tex]\frac{1}{yr}[/tex].
[tex]k[/tex] must be negative as death rate is constant and birth rate is zero. ([tex]k< 0[/tex]). Dimensionally, we can rewritte this constant as following:
[tex]k = -\frac{1}{\tau}[/tex]
Where [tex]\tau[/tex] is the time constant ([tex]\tau > 0[/tex]), measured in years.
We can find the solution of the ordinary differential equation by separating each variable:
[tex]\frac{dA}{dt} = -\frac{1}{\tau}\cdot A[/tex]
[tex]\int {\frac{dA}{A} } = -\frac{1}{\tau} \int \, dt[/tex]
[tex]\ln A(t) = -\frac{t}{\tau} + C[/tex]
[tex]A(t) = e^{-\frac{t}{\tau}+C }[/tex]
[tex]A(t) = e^{C}\cdot e^{-\frac{t}{\tau} }[/tex]
[tex]A(t) = A_{o}\cdot e^{-\frac{t}{\tau} }[/tex]
Where [tex]A_{o}[/tex] is the initial amount of atoms of Carbon-14.
The company has 15 employees, who earn a total of $2,500 in salaries each working day. They are paid each Monday for their work in the five-day workweek ending on the previous Friday. Assume that December 31, 2019, is a Tuesday, and all 15 employees worked the first two days of that week. Because New Year’s Day is a paid holiday, they will be paid salaries for five full days on Monday, January 6, 2020.
Answer: Debit salaries expense 3920
Credit salaries payable 3920
Step-by-step explanation:
Note that the total amount that the company will pay to the employees on Monday, January 6, 2020, is approximately $1,166.69.
How to compute the aboveBased on the given information, we can calculate the total amount that the company will pay to the employees on Monday, January 6, 2020.
The company has 15 employees, and they earn a total of $2,500 in salaries each working day. Therefore, the daily salary per employee is $2,500 divided by 15, which is approximately $166.67.
From December 31, 2019, to January 6, 2020, there are a total of 7 days, including New Year's Day, which is a paid holiday.
The employees worked the first two days of that week (December 31 and January 1), which means they will be paid for those two days.
On January 6, 2020, the employees will be paid salaries for five full days, which includes the remaining three days of the previous week and the upcoming week.
To calculate the total amount paid on January 6, 2020, we add the salary for the two worked days and the salary for the five full days:
Total amount paid = (Salary per day * 2) + (Salary per day * 5)
= ($166.67 * 2) + ($166.67 * 5)
≈ $333.34 + $833.35
≈ $1,166.69
Hence, the total amount that the company will pay to the employees on Monday, January 6, 2020, is approximately $1,166.69.

Step-by-step explanation:
There isn't enough information about what y would be if you meant for solving for the value of x. However, to get the equation to solve for x, all you need to do is to isolate the x by itself, which in this case you would need to add 7y to both sides. The answer should be x=7y+8

Consider the function shown on the graph.
Which function does the graph represent?
The quadratic function graphed is defined as follows:
f(x) = 3(x - 3)(x - 7).
How to define the function?We are given the roots for each function, hence the factor theorem is used to define the functions.
The function is defined as a product of it's linear factors, if x = a is a root, then x - a is a linear factor of the function.
The roots of the function are given as follows:
x = 3.x = 7.Hence the linear factors of the function are:
x - 3.x - 7.The function then is:
f(x) = a(x - 3)(x - 7)
When x = 8, y = 15, hence the leading coefficient a is obtained as follows:
5a = 15
a = 3.
Hence:
f(x) = 3(x - 3)(x - 7).
