A kayaker travels X miles per hour down stream for three hours. On the for our return trip, the kayak or travels 1 mph slower. How far did the kayak or travel in total?
The scale on a map of Virginia shows that 1 inch represents 15 miles. The actual distance from Richmond, VA, to Washington, D.C., is 110 miles. On the map, how many inches are between the two cities? Enter your answer as a mixed number with the fraction in simplest form.
The distance on the map is __ in.
Answer:
The answer to your question is: 7 1/3 inches
Step-by-step explanation:
Data
1 inch --------- 15 miles
Distance from Richmond to Washington = 110 miles
Use a rule of three to solve it
1 inch ----------------- 15 miles
x -------------------- 110 miles
x = 110x 1 /15
x = 110 / 15 simplify dividing by 5
x = 22/3
Convert it to a mix number
22/3 = 7 1/3 inches
Final answer:
On the map, 7.6 inches are between the two cities
Explanation:
To find out how many inches are between two cities on a map given the scale and the actual distance. The scale here is that 1 inch represents 15 miles. Therefore, for an actual distance of 110 miles, we simply divide the actual distance by the scale factor to obtain the distance on the map.
By setting up the proportion:
1 inch / 15 miles = x inches / 110 miles, we cross-multiply and solve for x,
which is the number of inches on the map. The calculation would be:
(1 inch / 15 miles) * 110 miles = 110 inches / 15 = 7 3/5 inches or 7.6 inches.

Sviatoslav solved the quadratic equation x^2-x-1=0 by completing the square. In the process, he came up with the equivalent equation (x+a)^2 = b, where a and b are constants. What is b?
Answer:
[tex]x=\frac{1+\sqrt5}{2}[/tex] and [tex]x=\frac{1-\sqrt5}{2}[/tex]
and b=[tex]\frac{5}{4}[/tex]
Step-by-step explanation:
We are given that a quadratic equation
[tex]x^2-x-1=0[/tex]
We have to solve the equation by completing square and find the value of b.
[tex](x)^2-2\times x\times \frac{1}{2}+(\frac{1}{2})^2-(\frac{1}{2})^2-1=0[/tex]
[tex](x-\frac{1}{2})^2-\frac{1}{4}-1=0[/tex]
[tex](x-\frac{1}{2})^2-\frac{1-4}{4}=0[/tex]
[tex](x-\frac{1}{2})-\frac{5}{4}=0[/tex]
[tex](x-\frac{1}{2})^2-(\frac{\sqrt5}{2})^2=0[/tex]
[tex](x-\frac{1}{2})^2=(\frac{\sqrt5}{2})^2[/tex]
[tex]x-\frac{1}{2}=\frac{\sqrt5}{2}[/tex] and [tex]x-\frac{1}{2}=-\frac{\sqrt5}{2}[/tex]
[tex]x=\frac{\sqrt5}{2}+\frac{1}{2}=\frac{1+\sqrt5}{2}[/tex]
And [tex]x=\frac{1}{2}-\frac{\sqrt5}{2}=\frac{1-\sqrt5}{2}[/tex]
Therefore,[tex]x=\frac{1+\sqrt5}{2}[/tex] and [tex]x=\frac{1-\sqrt5}{2}[/tex]
and b=[tex]\frac{5}{4}[/tex]
Final answer:
To complete the square for the equation x²-x-1=0, we add (1/2)² = 1/4 to both sides, resulting in the equivalent equation (x-1/2)² = 5/4, where b is 5/4 or 1.25.
Explanation:
To solve the quadratic equation x²-x-1=0 by completing the square, we need to transform the equation into the form (x+a)² = b. First, we would rearrange the equation to isolate the terms with x: x² - x = 1. The next step is completing the square by adding (1/2 ×-1)² = (1/2)² = 1/4 to both sides of the equation, resulting in x² - x + 1/4 = 1 + 1/4. Therefore, the complete square form is (x-1/2)²= 5/4 and the constant b is 5/4 or 1.25.
The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation , where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total?
a.55
b.60
c.130
d.150
Answer:
b. 60
Step-by-step explanation:
We have been given a formula [tex]5x+10y=800[/tex], where x represents the number of small vehicles and y represents the number of larger vehicles.
To find the number of small vehicles, we will substitute [tex]y=50[/tex] in the given equation as:
[tex]5x+10(50)=800[/tex]
[tex]5x+500=800[/tex]
[tex]5x+500-500=800-500[/tex]
[tex]5x=300[/tex]
[tex]\frac{5x}{5}=\frac{300}{5}[/tex]
[tex]x=60[/tex]
Therefore, 60 small vehicles were washed in total and option 'b' is the correct choice.
if (fx)=5x, what is f^-1(x)
Answer:
x/5
Step-by-step explanation:
To get the inverse function you need to leave the x alone and then switch variables ( f(x) = y)
f(x) = 5x
y = 5x
y/5 = x
Now that x is alone you switch the x for y and the y for x and you get:
x/5 = y
And this new y is the inverse function of f(x) ( f^-1(x))
f^-1(x) = x/5

Answer: d. 75% of the screen is occupied by the image
Step-by-step explanation:
First we have to find a relation between image area and screen area.
Image area is the product of image dimensions.
Screen area is the product of screen dimensions.
We have to divide the major image dimension between the major screen dimension
Major image dim/Major screen dim = 20/5 = 4
Now we have to multiply this relation by the minor screen dimension
Minor screen dim x 4 = 4 x 4 = 16
Then we have found 5/4 = 20/16
Now we can calculate what percent of the screen area is occupied by the image area.
Major image dim x minor image dim/Major screen dim x minor screen dim
Since major image dim = major screen dim, we have:
Minor image dim/Minor screen dim = 12/16 = 0.75 = 75% of the screen
Answer: d. 75% of the screen is occupied by the image

Suppose your state lottery has an expected value of
−34%.
If you spend $40 per month on lottery tickets, how much money would you be expected to lose in an average year?
We can expect to lose $
.
Final answer:
With an expected value of −34% for the state lottery and monthly spending of $40 on tickets, a person can expect to lose $13.60 monthly or $163.20 annually.
Explanation:
If the expected value of playing the state lottery is −34%, and a person spends $40 per month on lottery tickets, we can calculate the expected annual loss as follows:
Firstly, an expected value of −34% means that on average, for every dollar spent, you would expect to lose 34 cents. So for $40 spent in one month, the expected loss would be 34% of $40, which equals $13.60.
Next, we can find the expected loss for a year by multiplying the monthly loss by the number of months in a year:
Monthly expected loss: 0.34 × $40 = $13.60Annual expected loss: $13.60 × 12 months = $163.20Therefore, on average, you can expect to lose $163.20 per year if you continue spending $40 on lottery tickets every month.

The function is increasing where its slope is positive, decreasing where its slope is negative. Where the slope changes sign, there may be a point where the slope is 0 or undefined. The function is neither increasing nor decreasing there, so those points are not part of the intervals for increasing or decreasing.
The function is positive when it is above the x-axis, negative when it is below the x-axis. The function is neither positive nor negative where it is on the x-axis or where it is undefined.
The domain is the horizontal extent of the function. Any points where the function is undefined are excluded.
The range is the vertical extent of the function, all of the y-values where the function output is defined. Here, m(2) is not defined, so y=-7 is not an output at that point. However, y=7 is an output for m(-14 2/3). Likewise, m(9) does not have an output of 0, but m(3) does, so 0 is part of the range.
X- and y-intercepts are where the graph intersects the x- or y-axis, respectively. M(x) is undefined at (9, 0), so there is no x-intercept there.
A relative minimum is any point where the y-values increase on either side of the point. For m(x), the function is undefined at its relative minima, so it cannot be said to have any.
A relative maximum is any point where the y-value decreases on either side of the point. M(x) has one at the vertex of the parabolic segment.

A wall has been built with two pieces of sheetrock, a smaller one and a larger one. The length of the smaller one is stored in the variable small. Similarly, the length of the larger one is stored in the variable large. Write a single expression whose value is the length of this wall.
Answer:
The answer is: small+large.
Step-by-step explanation:
If the variable of the smaller sheetrock is stored in small:
var small.
And the variable of the larger sheetrock is stored in large:
var large.
The length of the wall will be the sum of the two pieces of sheetrock:
small+largeFor example:
var small = 5;
var large = 10;
small+large = 5 + 10 = 15 is the length of the wall.
Final answer:
To calculate the total length of a wall made with two sheets of sheetrock, use the expression 'small + large'. The correct unit for measuring large objects like walls is often feet, and including units is essential for clarity in measurements.
Explanation:
The question asks for an expression to calculate the total length of a wall built with two pieces of sheetrock with lengths stored in the variables small and large. Since the total length of the wall will be the sum of the lengths of the two pieces of sheetrock, the expression you would write is small + large. This will give you the length of the entire wall when you substitute in the numerical values for the lengths represented by the two variables.
When measuring large objects like walls, the appropriate unit of measure is often feet, as inches would be too small and miles or kilometers would be excessively large. It's important to always include units in your measurements to avoid confusion and to ensure that the measurements are useful for practical applications, such as buying fabric or building materials.

Order the function from the least steep slope to the steepest slope.
The functions ordered from the least steep slope to the steepest slope are: logarithmic (log(x)), linear (x), quadratic (x²), exponential (eˣ), and cubic (x³).
Explanation:To compare the steepness of the slopes for different types of functions, we consider the growth or decay rates of each function. The order is determined by the behavior of the functions as x increases.
1. Logarithmic function (log(x)): It grows slowly and approaches infinity as x increases, making it the least steep slope.
2. Linear function (x): It has a constant slope, making it steeper than logarithmic but less steep than quadratic, exponential, and cubic functions.
3. Quadratic function (x²): It increases faster than linear but slower than exponential and cubic functions.
4. Exponential function (eˣ): It grows at an increasing rate, making it steeper than quadratic but less steep than cubic.
5. Cubic function (x³): It has the steepest slope as x increases, making it the most rapidly increasing function.
This order is based on the general behavior of each function type and their rates of growth or decay. Understanding the characteristics of these functions helps in comparing and ordering them in terms of steepness.

Have to bake a lot of brownies to sell! You have plenty of flour, cocoa, milk, and oil, but you only have 6 1/2 sticks of butter. You need to know how many batches of brownies you can bake, based on your limited amount of butter. You can cook partial batches in order to use up every bit of butter, which will also help you to bake the most brownies possible. Each batch needs 3/4 of a stick of butter.
Answer: 8 + 2/3 batches of brownies you can bake.
Step-by-step explanation:
6 1/2 butter = 6 + 1/2 = (2·6 + 1)/2 = 13/2 sticks of butter, we have this
Since we have 13/2 sticks of butter and each batch of brownies needs 3/4 of a stick of butter, we have to divide the amount of butter we have between the amount of butter we use to bake a batch of brownies.
13/2 butter ÷ 3/4 butter/batch = 13·4/2·3 batches = 52/6 batches = 8 + 2/3 batches
Answer: 8 + 2/3 batches of brownies you can bake.
[tex]\textit{\textbf{Spymore}}[/tex]
By dividing the total amount of butter (13/2 sticks) by the amount required per batch (3/4 stick), we find that it's possible to make 8 full batches of brownies with 6 1/2 sticks of butter, with some butter left over.
To determine how many batches of brownies you can bake with 6 1/2 sticks of butter, you have to divide the total amount of butter you have by the amount required for one batch. Since each batch requires 3/4 stick of butter, you calculate as follows:
Total sticks of butter: 6 1/2
Required per batch: 3/4
Now convert 6 1/2 to an improper fraction: 6 1/2 = 13/2.
Next, calculate the number of batches by dividing the total butter by the butter per batch:
Number of batches = (13/2) / (3/4) = (13/2) * (4/3) = 52/6
When you simplify 52/6, you get 8 with a remainder, meaning you can make 8 full batches of brownies, and you will have some butter left over.
A teacher divides the students into three groups for project each group has the same number of students in the total of number students prime or composite
Answer:
The total number of students is composite
Step-by-step explanation:
* Lets explain how to solve the problem
- A teacher divides the students into three groups for project
- Each group has the same number of students
- We need to know the total number of students is prime number or
composite number
∵ The least number of any group is 2 students
∵ There are three groups
∵ The number of students in each group equal
∴ The least number of the students is 6
∵ Any number of students must be multiple of 3 because it will
divide by 3
∵ Any prime number has only two factors 1 and itself
∵ Any multiple of 3 (except 3) has more than two factors
∵ The class can not be 3 students because when divided to 3
groups each group will have 1 students and the least number of
students in a group is 2
∴ The number of the students in the class must be composite
Final answer:
The question deals with evenly dividing students into three groups for a group assignment, indicating that the total number of students is composite, as it is divisible by three.
Explanation:
The question involves dividing a number of students into groups for a group assignment. A key concept here is understanding whether the total number of students is a prime or composite number.
If the students were evenly divided into three groups, this implies that the total number must be divisible by three, making it a composite number.
Examples of group work dynamics include cases where students divide work equally but one ends up doing the most of it, evenly distributing tasks, or each taking on different aspects of a complex problem.
A stand-up comedian uses algebra in some jokes, including one about a telephone recording that announces "You have just reached a pure imaginary number. Please multiply by i and dial again." Explain the joke.
Answer:
i * i = -1
Step-by-step explanation:
W hen you multiply an imaginary number or i number by another imaginary pure number, the answer is going to be a negative number, due that i *i= -1. The joke is funny because if you do what the recording is saying there you won't have a pure imaginary number and if you dial again, the same would happen again and again.
Answer:
When we work with imaginary numbers, we have that
i = √(-1)
then, we have that i*i = √(-1)*√(-1) = -1
An imaginary number is a number of form A + B*i, where A and B are real numbers.
Now, a purely imaginary number is a number of the form B*i, where B is a real number.
Then, if we multiply this number by i, we have that:
B*i*i = B*(-1) = -B
now we have a real number.
The joke is that now you can "reach" a real number.

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(275)?
Houses sell on the market for an average of $275,000 and stay on the market an average of 275 days before being sold.
Houses sell for an average of $275,000.
f(275) indicates houses stay on the market an average of 275 days before being sold.
f(275) represents the average number of days houses stay on the market before being sold for $275,000.
The problem states:
f(p) is the average number of days a house stays on the market before being sold for price p in $1,000s
So we know:
p is the price in $1000s and
f(p) is the number of days before its sold for p
This means f(275) would be the number of days before its sold for 275,000 (since p is in $1000s).
The answer is:
f(275) represents the average number of days houses stay on the market before being sold for $275,000.
The statement "f(275) represents the average number of days houses stay on the market before being sold for $275,000" best describes the meaning of f(275).
Given,
Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s.
In the given function f(p), the variable p represents the price of a house in thousands of dollars ($1,000s), and f(p) represents the average number of days a house stays on the market before being sold for that price.
Therefore, when you evaluate f(275), it tells you the average number of days houses stay on the market before being sold for $275,000.

What is the leading coefficient of this polynomial when written in standard form?
1-2x+5x^4
Answer:
5!!
Step-by-step explanation:
When writing the polynomial in standard form, we have:
5X⁴ - 2X + 1
The leading coefficient is 5, since it's part of the term with the highest degree.
Final answer:
The leading coefficient of the polynomial 1 - 2x + 5x⁴ in standard form is 5, as standard form requires terms to be in descending powers of x.
Explanation:
The question asks to identify the leading coefficient of a polynomial when written in standard form. The given polynomial is 1 - 2x + 5x⁴. The standard form of a polynomial requires the terms to be written in descending powers of x. Therefore, the standard form of the given polynomial is 5x⁴ - 2x + 1. The leading coefficient is the coefficient of the term with the highest power of x, which in this case is 5 for the term 5x⁴.
