n = 15 when p=$213.75 and r=$9.50

Step-by-step explanation:

Given

p = overtime pay

n = number of hours

r = hourly pay rate

It is also given that the pay for working hours varied directly with Number of hours and hourly pay rate jointly

So

It can be denoted as:

p ∝ nr

It can also be written as:

[tex]p = knr[/tex]

where k is the constant of proportionality

Putting the given values of p,n and r in the equation

[tex]103.44 = k * 8 * 8.62\\103.44 = 68.96k\\k = \frac{103.44}{68.96}\\k = 1.5[/tex]

So the equation is now,

p = 1.5nr

Putting

p = 213.75

r = 9.50

[tex]213.75 = 1.5 * n * 9.50\\213.75 = 14.25n\\n = \frac{213.75}{14.25}\\n = 15[/tex]

Hence,

n = 15 when p=$213.75 and r=$9.50

Step-by-step explanation:

Given equation is:- [tex]C=35n+40[/tex]

where, C=Cost in dollars, n=hours.

Now, Amy charge $40 for service call and $35 for per hour service.

So,

For 0 hours:

[tex]C=35n+40[/tex]

[tex]C=(35\times 0)+40[/tex]

[tex]C=0+40[/tex]

[tex]C=40[/tex]

Therefore for 0 hours Amy charge $40.

For 1 hours:

[tex]C=35n+40[/tex]

[tex]C=(35\times 1)+40[/tex]

[tex]C=35+40[/tex]

[tex]C=75[/tex]

Therefore for 1 hours Amy charge $75.

For 2 hours:

[tex]C=35n+40[/tex]

[tex]C=(35\times 2)+40[/tex]

[tex]C=70+40[/tex]

Answer:

Step-by-step explanation:

The cyclist's speed is 0.35 kilometers per minute. She will travel 0.7 kilometers in 2 minutes.

The question deals with converting speed from kilometers per hour to kilometers per minute, and also calculating distance given a certain time and speed.

First, we convert speed from kilometers per hour to kilometers per minute. There are 60 minutes in an hour, so we divide the speed of the cyclist (21 kilometers per hour) by 60: 21/60 = 0.35 kilometers per minute.

Next, we calculate the distance the cyclist will travel in 2 minutes. Distance equals rate times time, so we multiply the cyclist's speed by the time: 0.35 kilometers per minute * 2 minutes = 0.7 kilometers.

Answer:

We will buy it at $9.95 plus  5% tax because it is slightly cheaper than other price

Step-by-step explanation:

$9.95 x 18 = 179.10 + 5% sales tax(8.95) = 188.055

$9.75 x 18 = 175.50 + 15 = 190.50

hence sales tax can be get back by submitting monthly return file. so the first method is cheaper than second one,

The first shop offers a better price for 18 rolls of film. You will pay [tex]$179.10[/tex]for 18 rolls of film at the first shop.

Let's calculate the total cost for each shop:

For the first shop:

- The price per roll is [tex]$9.95[/tex].

- There is a 5% sales tax.

- The total cost without tax for 18 rolls is [tex]18 rolls * $9.95/roll = $179.10[/tex].

- The sales tax on this amount is 5% of [tex]$179.10[/tex], which is [tex]0.05 = $8.955.[/tex]

- The total cost including tax is [tex]$179.10[/tex][tex]+ $8.955[/tex] [tex]=$188.055.[/tex]

 For the second shop:

- The price per roll is [tex]$9.75.[/tex]

- There is no sales tax.

- The shipping cost is a flat rate of [tex]$15.00.[/tex]

- The total cost for 18 rolls, excluding shipping, is 18 rolls *[tex]$9.75/roll[/tex] [tex]= $175.50.[/tex]

- Adding the shipping cost, the total cost is [tex]$175.50[/tex][tex]+ $15.00 = $190.50[/tex].

 Comparing the two total costs:

- First shop: [tex]$188.055[/tex] (approximately [tex]$179.10[/tex] without rounding the tax)

- Second shop: [tex]$190.50[/tex]

 The first shop offers a better price for 18 rolls of film. You will pay approximately [tex]$179.10[/tex] for 18 rolls of film at the first shop, which is less than the [tex]$190.50[/tex] you would pay at the second shop.

Answer: the answer would be c

Step-by-step explanation:

Kyle will have more time to play video games

Solution:

From given question,

Kyle’s parents told him that for every 5 hours of homework or reading he completes, he will be able to play 3 hours of video games.

5 hours of homework = 3 hours of video games

Victor’s parents told their son that he can play 30 minutes for every hour of homework or reading time he completed.

1 hour of homework = 30 minutes of playtime

Suppose if victor spends 5 hours doing homework or reading, then he could play,

5 hours of victor homework = 30 minutes x 5 = 150 minutes of play

That is,

150 minutes = 120 + 30 = 2 hours 30 minutes

This 2 hours 30 minutes playtime of victor is less than kyle playtime (which is 3 hours )

So Kyle gets more play time

Answer:

6.40=$12.60

Step-by-step explanation:

First, make the equation following the problem.

$7.50 + $0.85 = $12.60

Then, find the number of miles.

$7.50 * $0.85 = $6.40

$6.40=$12.60

Don't need to solve it because it is asking for the equation.

This is a linear equation problem in Mathematics. The equation to find out the number of miles for the given total charge would be 7.50 + 0.85m = 12.60. Through algebraic manipulation, it is found that the shuttle travelled 6 miles.

The subject of this question is in the field of Mathematics, specifically under linear equations in algebra. In this problem, the customer is charged a flat fee of $7.50 and then an additional $0.85 per mile. The total charge for this trip was $12.60, and we're tasked with finding the number of miles covered for this charge.

The equation to solve this problem would be 7.50 + 0.85m = 12.60, where 'm' represents the miles. We subtract 7.50 from both sides, then we get: 0.85m = 5.1. To solve for 'm', we divide both sides by 0.85, and we receive m = 6 miles.

Answer:

Domain: (-∞,∞) or  -∞ <[tex]x[/tex]<∞

Range: [1,∞) or [tex]y\geq 1[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=x^2-2x+2[/tex]

To find range and domain of the function.

Solution:

The given function is a second degree function as the highest exponent of the variable is 2. Thus, it is a quadratic function.

For all quadratic functions the domain is a set of all real numbers. So, the domain can be given as: (-∞,∞) or  -∞ <[tex]x[/tex]<∞

In order to find the range of the quadratic function, we will first determine if the function has a minimum point or the maximum point.

For a quadratic equation : [tex]ax^2+bx+c[/tex]

1) If [tex]a>0[/tex] the function will have a minimum point.

2) If  [tex]a<0[/tex] the function will have a maximum point.

For the given function: [tex]f(x)=x^2-2x+2[/tex]

[tex]a=1[/tex] which is greater than 0, and hence it will have a minimum point.

To find the range we will find the coordinates of the minimum point or the vertex of the function.

The x-coordinate [tex]h[/tex] of the vertex of a quadratic function is given by :

[tex]h=\frac{-b}{2a}[/tex]

Thus, for the function:

[tex]h=\frac{-(-2)}{2(1)}[/tex]

[tex]h=\frac{2}{2}[/tex]  [Two negatives multiply to get a positive]

[tex]h=1[/tex]

To find y-coordinate of the vertex can be found out by evaluating [tex]f(h)[/tex].

[tex]k=f(h)[/tex]

Thus, for the function:

[tex]k=f(1)=(1)^2-2(1)+2[/tex]

[tex]k=f(1)=1-2+2[/tex]

[tex]k=f(1)=1[/tex]

Thus, the minimum point of the function is at (1,1).

thus, range of the function is:

[1,∞) or [tex]y\geq 1[/tex]

Answer:

Step-by-step explanation:

We begin with the expression: [tex]0.5+(-\frac{3}{4} )+0.25-(-\frac{4}{5} )[/tex]

First, we need to convert the fractions into decimals to make this easier.

[tex]-\frac{3}{4}=-0.75[/tex] and [tex]-\frac{4}{5} =-0.8[/tex]

Once we have this, we can simplify it

[tex]0.5-0.75+0.25-(-0.8)\\\\0.5-0.75+0.25+0.8\\\\0.75-0.75+0.8\\\\0.8[/tex]

Answer:

[tex]\frac{24}{25}[/tex]

Step-by-step explanation:

Given

cosA = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]

Then the opposite side using Pythagorean triple is 4, thus

sinA = [tex]\frac{4}{5}[/tex]

Using the trigonometric identity

sin2A = 2 sinAcosA, then

sin2A = 2 × [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex]

         = [tex]\frac{2(4)(3)}{5(5)}[/tex] = [tex]\frac{24}{25}[/tex]

Answer:

[tex]\sin(2A)=\frac{24}{25}[/tex]

Step-by-step explanation:

Double angle identity for sine is

[tex]\sin(2A)=2\sin(A)\cos(A)[/tex].

We know [tex]\cos(A)[/tex]. We now need to find [tex]\sin(A)[/tex] to find our answer.

Recall the following [tex]Pythagorean Identity[/tex]:

[tex]\sin^2(A)+\cos^2(A)=1[/tex].

Replace [tex]\cos(A)[/tex] with [tex]\frac{3}{5}[/tex]:

[tex]\sin^2(A)+(\frac{3}{5})^2=1[/tex]

[tex]\sin^2(A)+\frac{9}{25}=1[/tex]

Subtract [tex]\frac{9}{25}[/tex] on both sides:

[tex]\sin^2(A)=1-\frac{9}{25}[/tex]

[tex]\sin^2(A)=\frac{25}{25}-\frac{9}{25}[/tex]

[tex]\sin^2(A)=\frac{25-9}{25}[/tex]

[tex]\sin^2(A)=\frac{16}{25}[/tex]

Now to finally get the value of [tex]\sin(A)[/tex] take the square of both sides:

[tex]\sin(A)=\pm \sqrt{\frac{16}{25}}[/tex]

Since [tex]A[/tex] is in the interval [tex](0,90)[/tex], then [tex]\sin(A)>0[/tex].

[tex]\sin(A)=\sqrt{\frac{16}{25}}[/tex]

[tex]\sin(A)=\frac{\sqrt{16}}{\sqrt{25}}[/tex]

[tex]\sin(A)=\frac{4}{5}[/tex]

So let's finally find the numerical value of [tex]\sin(2A)[/tex].

[tex]\sin(2A)=2\sin(A)\cos(A)[/tex]

[tex]\sin(2A)=2\cdot \frac{4}{5} \cdot \frac{3}{5}[/tex]

[tex]\sin(2A)=\frac{2(4)(3)}{5(5)}[/tex]

[tex]\sin(2A)=\frac{24}{25}[/tex]

Side note:

If [tex]A[/tex] is between 0 and 90 degrees, then we are in the first quadrant.

If we are in the first quadrant, both [tex]x=\cos(A)[/tex] and [tex]y=\sin(A)[/tex] are positive.

Final answer:

After subtracting the manufacturing costs of the computer, monitor, and scanner from the selling price for one unit and multiplying by 408 customers, the approximate total profit is $247,050.00, which rounds to option C. $240,000.00.

Explanation:

To calculate the profit the company makes for each computer sold at $1,196.91 after giving away a monitor and a scanner, we need to subtract the cost of manufacturing the computer, monitor, and scanner from the selling price, and then multiply it by the number of customers. The costs for the computer, monitor, and scanner are $393.29, $151.44, and $46.39 respectively. Therefore, the total cost of manufacturing one set is:

Total cost = Cost of computer + Cost of monitor + Cost of scanner

Total cost = $393.29 + $151.44 + $46.39 = $591.12

The profit for one computer set would then be:

Profit per computer = Selling price - Total cost

Profit per computer = $1,196.91 - $591.12 = $605.79

To find the total profit for 408 customers, we multiply the profit per computer by the number of customers:

Total profit = Profit per computer × Number of customers

Total profit = $605.79 × 408 ≈ $247,060.32

When rounding to the nearest 50 dollars, we get:

Total profit ≈ $247,050.00

The closest answer to this would be option C. $240,000.00.
