Final answer:
To find the amount for the monthly payments for a plasma-screen TV, subtract the down payment from the total cost and divide by the number of installments. The equation is: Monthly Payment = (Total Cost - Down Payment) / Number of Installments, which calculates to $195.75.
Explanation:
The student is seeking to find an equation that represents the cost of a plasma screen television being paid off with a down payment and equal monthly installments. Given the total cost of the television is $5250 and the down payment is $552, we can start by calculating the remaining balance after the down payment, which will be paid in 24 equal monthly payments.
First, subtract the down payment from the total cost to find the balance that needs to be paid in installments:
Total cost of television: $5250Down payment: -$552Balance to be paid in monthly installments: $5250 - $552 = $4698Next, we divide the balance by the number of monthly payments to find the amount of each payment:
Number of monthly payments: 24Monthly payment amount: $4698 / 24 = $195.75Therefore, the equation that represents the monthly payment after the down payment is:
Monthly Payment = (Total Cost - Down Payment) / Number of Installments
Applying the given numbers we get:
Monthly Payment = ($5250 - $552) / 24
Plugging in the values:
Monthly Payment = $4698 / 24 = $195.75
Scientists are studying the temperature on a distant planet. Let
y
represent the temperature (in degrees Celsius). Let
x
represent the height above the surface (in kilometers). Suppose that
x
and
y
are related by the equation
y=41-3x
.
Answer the questions below.
Note that a change can be an increase or a decrease.
For an increase, use a positive number. For a decrease, use a negative number.
what is the temperature on the surface of the planet?
what is the temperature change for each kilometer we go up from the surface?
Answer:
The temperature on the surface of the planet is 41 °C.The tempearture decreases 3 °C when the height increases 1 km.Step-by-step explanation:
The given equation is
[tex]y=41-3x[/tex]
Where [tex]x[/tex] is the height above the surface and [tex]y[/tex] is the temperature in degrees Celsius.
Now, the temperature on the surface can be find when the height above the surface is zero, that is [tex]x=0[/tex]. So, we replace this value and solve for [tex]y[/tex]
[tex]y=41-3x=41-3(0)\\y=41[/tex]
Therefore, the temperature on the surface of the planet is 41 °C.
The second question is about the constant rate of change of the given relation, which is also the slope of the linear expression. That constant rate of change is always the coefficient of variable [tex]x[/tex]. Therefore, the ratio of change is [tex]r=-3[/tex]. Which means the tempearture decreases 3 °C when the height increases 1 km.
The decreasing behaviour is deduct from the ratio of change, when it's negative, that means the function decreases, like in this case.

During a 52 week period, a company paid overtime wages for 19 weeks and hired temp help for 11 weeks. During 5 weeks, the company paid overtime AND hired temp help. If an auditor randomly examined the payroll for only one week, whats the probability that the payroll for that week contained overtime wages or temp help wages? ...?
The probability that the payroll for one week contained overtime wages or temporary help is [tex]\boxed{\frac{10}{13}}[/tex].
Further explanation:
It is given that during a [tex]52[/tex] week period, a company paid overtime wages for [tex]19[/tex] weeks and hired temporary help for [tex]11[/tex] weeks.
During [tex]5[/tex] weeks, the company paid overtime and hired temporary help.
Calculation:
A company paid overtime wages for [tex]19[/tex] weeks and [tex]5[/tex] weeks during the [tex]52[/tex] week period.
Therefore, the probability of overtime wages [tex]P(O)[/tex] is calculated as follows:
[tex]\begin{aligned}P(O)&=\dfrac{19}{52}+\dfrac{5}{52}\\&=\dfrac{19+5}{52}\\&=\dfrac{24}{52}\end{aligned}[/tex]
The probability of overtime wages is [tex]\frac{24}{52}[/tex].
The same company hired temporary help for [tex]11[/tex] weeks and [tex]5[/tex] weeks during the [tex]52[/tex] week period.
Therefore, the probability of temporary help [tex]P(H)[/tex] is calculated as follows:
[tex]\begin{aligned}P(H)&=\dfrac{11}{52}+\dfrac{5}{52}\\&=\dfrac{11+5}{52}\\&=\dfrac{16}{52}\end{aligned}[/tex]
The probability of temporary help is [tex]\frac{16}{52}[/tex].
Now, the combined probability [tex]P[/tex] that the payroll for one week contained overtime wages or temporary help is calculated by adding the probabilities of overtime wages and temporary help as follows:
[tex]\begin{aligned}P&=\dfrac{24}{52}+\dfrac{16}{52}\\&=\dfrac{24+16}{52}\\&=\dfrac{40}{52}\\&=\dfrac{10}{13}\end{aligned}[/tex]
The probability that the payroll for one week contained overtime wages or temporary help is [tex]\boxed{\dfrac{10}{13}}[/tex].

example of why division is not associative.
Division is not associative, as if you look at one of the operands to a nest of divisions, the result will vary either in proportion to it or inversely to it depending on whether it's to the right of an odd or even number of divisions. And the basic associative law changes the number of operations the rightmost operand is to the right of by 1.

lottie needs a driver. Drive A is offering his services for an initial $200 in addition to $80 per hour. Driver B is offering this service for an intal $230 and an addition of $70 per hour When will the two drivers charge the same amount
Driver A and Driver B will charge the same amount after 3 hours of service.
Explanation:The subject of this question is a problem involving linear equations, a topic in mathematics. Specifically, it pertains to the intersection point of two linear functions, representing the costs charged by the two drivers over time. Let's denote the driving time as 't' (in hours) and the total cost as 'C' to solve it.
Driver A's cost function could be formulated as C = 200 + 80t, while Driver B's as C = 230 + 70t.
To find out when both drivers will charge the same amount, set these two equations equal to each other:
200 + 80t = 230 + 70t
This simplifies to 10t = 30 after subtracting 200 from both sides and 70t from both sides. Finally, dividing by 10 gives us t = 3.
Therefore, both drivers would charge the same amount after 3 hours of service.

At first public inquiry showed there were 637000 women motorcyclists in the US up from 437000 just 8 years ago before it. Find the percent of increase in the number of women motorcyclists during these 8 years
The percent of increase in the number of women motorcyclists over the 8-year period is approximately 45.77%, calculated by finding the difference between the final and initial number of motorcyclists, dividing by the initial number, and converting the ratio to a percentage.
Explanation:To calculate the percent of increase in the number of women motorcyclists over the 8-year period provided, follow these steps:
Determine the initial and final values. Initial value: 437,000; Final value: 637,000.
Calculate the increase by subtracting the initial value from the final value: 637,000 - 437,000 = 200,000.
Divide the increase by the initial value to find the increase ratio: 200,000 / 437,000 ≈ 0.4577.
Multiply the increase ratio by 100 to convert it to a percentage: 0.4577 * 100 ≈ 45.77%.
Therefore, the percent of increase in the number of women motorcyclists during these 8 years is approximately 45.77%.

Solve. 3t < –15 (1 point)
t < –5
t > –5
t < –45
t > –45
The solution to the inequality 3t < –15 is t < –5, attained by dividing both sides by 3.
Explanation:The student's question involves solving an inequality, specifically 3t < –15. To solve for t, we need to isolate t on one side of the inequality. This can be done by dividing both sides of the inequality by 3. The solution to the inequality is:
Divide both sides by 3: t < –5Therefore, the correct answer to the inequality 3t < –15 is t < –5. The other options such as t > –5, t < –45, and t > –45 are incorrect.

x^2-14x-4=0, solve by completing the square
The solution of the equation found by completing the square are;
x = 7 - √(53) and 7 + √(53)
What is the completing the square method?Completing the square method involves writing the quadratic expression of the form a·x² + b·x + c as (x + d)² + e, where d and e are constants.
Moving the constant to one side of the equation, we get;
x² - 14·x = 4
We complete the square on the left side of the equation by adding and subtracting the square of the half the coefficient of x term inside the parenthesis. Therefore, we add and subtract (-14/2)² = 49, as follows;
(x² - 14·x + 49) - 49 = 4
Therefore; (x - 7)² - 49 = 4
The -49 is moved to the right side of the equation to get;
(x - 7)² = 4 + 49 = 53
Taking the square root of both sides, we get;
x - 7 = ± √(53)
Therefore; x = 7 ± √(53)
The solution is; x = 7 + √(53) and 7 - √(53)

The amount of weight that Sam loses is directly proportional to the number of hours he spends exercising. If Sam loses a pound of weight for each 3 hrs of exercise, how many hours must he spend exercising to lose 25 lbs?
A) 25 hrs
B) 50 hrs
C) 75 hrs
D) 80 hrs
Answer:
The answer is C. 75 hours.
Step-by-step explanation:
In order to determine the hours, we have to know about direct proportionality.
The direct proportionality happens when two variables increase at the same time and their rate is a constant. It means that if one variable is increased, so the other variable will be increased too.
I have attached an image that shows a graph of two variables with direct proportionality.
In this case, we can get the constant of both variables: losing weight and the spending time.
[tex]k=\frac{Weight}{Time}=\frac{1}{3} =0.33[/tex]
Then we need to know how many hours Sam will spend to lose 25 lbs:
[tex]\frac{25}{T}=k=0.33\\ T=\frac{25}{0.33}\\ T=75.76[/tex] hours.
Finally, Sam needs to spend 75 hours to lose 25 lbs.
