Eric plans to rent a Beach House for a week. He has a coupon for 20% off the daily base rate of $200. He will also have to pay an additional $20 a day for utilities. Which expression represents the situation. (d represents the number of days)

Answers

Answer 1

Answer: 180 d is the required expression.

Step-by-step explanation:

Since,  He has a coupon for 20% off the daily base rate of $200.

Therefore, His daily base cost = 80 % of 200 = [tex]\frac{20\times 80}{100}[/tex] = $ 160

Additional cost he pay in a day = $20

Therefore, his total cost of one day = 160 + 20 = 180

Thus, his total cost in d days = 180 d

Which is the required expression.


Answer 2

Answer:

180d C)

Step-by-step explanation:

40 is 20 percent of 200, if you remove 40 from 200 you get 160. then add 20 and you have 180.

How do you solve
8(x-1)-2x=-(x+50)

Answers

8X-8-2X = X+50
8x-2x-x= 50+8
5x=58
x=58/5   
= 11.6


The solution to the equation 8(x-1) - 2x = -(x + 50) is x = -6.

To solve the equation 8(x-1) - 2x = -(x + 50).

First, distribute the 8 to the terms inside the parentheses:

8x - 8 - 2x = -(x + 50)

Simplify the left side of the equation:

6x - 8 = -(x + 50)

Distribute the negative sign to the terms inside the parentheses:

6x - 8 = -x - 50

Isolate the x terms on one side and the constant terms on the other side:

6x + x = -50 + 8

Combine like terms:

7x = -42

Divide both sides of the equation by 7:

7x / 7 = -42 / 7

x = -6

Therefore, the solution to the equation 8(x-1) - 2x = -(x + 50) is x = -6.

A computer training institute has 625 students that are paying a course fee of $400. Their research shows that for every $20 reduction in the fee, they will attract another 50 students. What fee should the school charge to maximize their revenue?
$275
$380
$320
$325

Answers

1.
If no changes are made, the school has a revenue of :

625*400$/student=250,000$

2.
Assume that the school decides to reduce n*20$.

This means that there will be an increase of 50n students.

Thus there are 625 + 50n students, each paying 400-20n dollars.

The revenue is: 

(625 + 50n)*(400-20n)=12.5(50+n)*20(20-n)=250(n+50)(20-n)

3.

check the options that we have, 

a fee of $380 means that n=1, thus 

250(n+50)(20-n)=250(1+50)(20-1)=242,250   ($)


a fee of $320 means that n=4, thus

 250(n+50)(20-n)=250(4+50)(20-4)=216,000    ($)


the other options cannot be considered since neither 400-275, nor 400-325 are multiples of 20.

Conclusion, neither of the possible choices should be applied, since they will reduce the revenue.

Answer: it’s D $325

What is the five-number summary for these data?
Minimum = 72, Q1 = 83, median = 89, Q3 = 92, maximum = 94
Minimum = 80, Q1 = 85, median = 89, Q3 = 91, maximum = 93
Minimum = 80, Q1 = 83, median = 90, Q3 = 92, maximum = 93
Minimum = 72, Q1 = 85, median = 90, Q3 = 91, maximum = 94

Answers

The first step to do is to arrange the data set from least to greatest.

72  80  83  85  88 90  91 92  93  94

From the arrangement, we can see that the minimum is 72 and the maximum is 94. Next, the median is the middle number of the data. Since there are 10 data points, we take the average of the middle 2 numbers. The median is (88+90)/2 = 89. 

When you talk about the quartiles, you draw divisions in your set. Q₁ is the middle data between the smallest and the median; Q₂ is the median; and Q₃ is the middle data between the largest and the median.


72  80  83  85  88 | 89 | 90  91 92  93  94

Q₁ is 83
Q₂ is 89
Q₃ is 92

Therefore, in summary, the answer is: Minimum = 72, Q1 = 83, median = 89, Q3 = 92, maximum = 94

What is the rate of change between the interval x = π and x = three pi over two?

Answers

Final answer:

The rate of change between x = π and x = three pi over two is 6/π.

Explanation:

The rate of change between the interval x = π and x = three pi over two can be found by calculating the slope of the line connecting these two points on the graph. In this case, we can calculate the slope by finding the difference in y-values and dividing it by the difference in x-values:

Slope = (y₂ - y₁) / (x₂ - x₁) = (2 - (-1)) / (π - 3π/2) = (2 + 1) / (3π/2 - π) = 3 / (π/2) = 6 / π

Therefore, the rate of change between the interval x = π and x = three pi over two is 6/π.

Final answer:

The rate of change between x = π and x = three pi over two is 6/pi.

Explanation:

The rate of change between the interval x = π and x = three pi over two can be found by determining the slope of the line connecting the two points on the graph corresponding to these x-values.

Using the coordinates (pi, -1) and (3 pi over 2, 2), we can calculate the slope as follows:

Slope = (change in y)/(change in x) = (2 - (-1))/(3 pi over 2 - pi) = 3/(pi/2) = 6/pi

So, the rate of change between x = π and x = three pi over two is 6/pi.

The Cool Company determines that the supply function for its basic air conditioning unit is S(p) = 40 + 0.008p^3 and that its demand function is D(p) = 200 - 0.16p^2, where p is the price. Determine the price for which the supply equals the demand.

Answers

In this item, we are to determine the price to which there would be a breakeven between the supply and demand. This can be done by equating the equations given for each as shown below.
       S(p) = D(p)
     40 + 0.008p³ = 200 - 0.16p²

We transpose all the terms to left side of the equation. 
     0.008p³ + 0.16p² - 160 = 0
Then, we factor out the given function. This can either be done through long division or synthetic division. Divide the equation by 0.008.
        p³ + 20p² - 20000 = 0

One of the roots of the equation is 21.86. This is the only real root of the equation and the rest are imaginary. 

Hence, the price should be approximately $21.86 before the demand and supply is breakeven.

Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)


Answers

Final answer:

The circumference of a circle with a given area is 75.40 meters

Explanation:

To find the circumference of a circle, we can use the formula C = 2πr, where C is the circumference and r is the radius. First, we need to find the radius from the given area.

The formula for the area of a circle is [tex]A = \pi r^2[/tex]

Rearranging the formula, we get [tex]r = \sqrt{(A/\pi \p).[/tex]

Now, substitute the given area (452.16 square meters) into the formula and solve for r:

[tex]r = \sqrt{(452.16/3.1416)[/tex]

=  12.00 meters

Parent function of greatest integer function:

[tex]f(x)=[x][/tex]

For x = 0 to x= 1 , f(x)=0

For x =1 to x=2 , f(x)=1

We are given a function,

For x = 0 to x= 1 , f(x)=-6

For x = 1 to x= 2, f(x) = -5

If we shift 6 unit down the parent function. We will get original function.
