For Kelley to pay for half of a new phone, she must put in 22.5 hours at her job. Her daily workday lasts three hours. Let x stand for the days she worked and y for the number of hours she still needs to put in to pay for the phone. hours overall still required to labor after x days.
What does the y-intercept of the graph represent?In algebra, the letter "x" is frequently used to denote a value that is still unknown. The term "variable" or "unknown" is used to describe it. Not only can a variable be "y," "w," or any other letter, name, or symbol, it can also be "x."
Time used minus the rate of work equals the amount of work completed. Time taken divided by the rate of work equals one. Time = 1 / Rate of Work. Work completed in a day equals 1/x if a task is completed over x days.The x-intercept and y-intercept are the points at which a line crosses the x- and y-axes, respectively.The location where a graph crosses the y-axis is known as the y-intercept.

Peter gave away 5/12 of his marbles and had 70 left how many marbles he had at first
Answer:
There were 120 marbles to start
Step-by-step explanation:
Let x be the number of marbles at the start
x* 5/12 = number of marbles given away
1 -5/12 = 7/12 = fraction of marbles left
x * 7/12 = number of marbles left
x * 7/12 = 70
Multiply each side by 12/7
x *7/12 * 12/7 = 70 * 12/7
x =120
There were 120 marbles to start
A tank contains 9,000 L of brine with 12 kg of dissolved salt. Pure water enters the tank at a rate of 90 L/min. The solution is kept thoroughly mixed and drains from the tank at the same rate. (a) How much salt is in the tank after t minutes? y = kg (b) How much salt is in the tank after 20 minutes? (Round your answer to one decimal place.) y = kg
Therefore, After 20 minutes, there are approximately 11.9 kg (rounded to one decimal place) of salt in the tank.
To solve this problem, we need to consider the rate of change of the amount of salt in the tank over time.
(a) Let's denote the amount of salt in the tank after t minutes as y (in kg). We can set up a differential equation to represent the rate of change of salt:
dy/dt = (rate of salt in) - (rate of salt out)
The rate of salt in is given by the concentration of salt in the incoming water (0 kg/L) multiplied by the rate at which water enters the tank (90 L/min). Therefore, the rate of salt in is 0 kg/L * 90 L/min = 0 kg/min.
The rate of salt out is given by the concentration of salt in the tank (y kg/9000 L) multiplied by the rate at which water leaves the tank (90 L/min). Therefore, the rate of salt out is (y/9000) kg/min.
Setting up the differential equation:
dy/dt = 0 - (y/9000)
dy/dt + (1/9000)y = 0
This is a first-order linear homogeneous differential equation. We can solve it by separation of variables:
dy/y = -(1/9000)dt
Integrating both sides:
ln|y| = -(1/9000)t + C
Solving for y:
y = Ce^(-t/9000)
To find the particular solution, we need an initial condition. We know that at t = 0, y = 12 kg (the initial amount of salt in the tank). Substituting these values into the equation:
12 = Ce^(0/9000)
12 = Ce^0
12 = C
Therefore, the particular solution is:
y = 12e^(-t/9000)
(b) To find the amount of salt in the tank after 20 minutes, we substitute t = 20 into the particular solution:
y = 12e^(-20/9000)
y ≈ 11.8767 kg (rounded to one decimal place)

Two homebuyers are financing $137,000 to purchase a condominium. They obtained a 15-year, fixed-rate loan with a rate of 5.05%. They have been given the option of purchasing up to three points to lower their rate to 4.87%. How much will the three points cost them? a. $6,919 b. $6,199 c. $4,110 d. $4,101
The cost of three points for the homebuyers is $739.80.
To calculate the cost of three points for the homebuyers, we need to determine the value of each point and then multiply it by three.
Given:
Loan amount: $137,000
Interest rate without points: 5.05%
Interest rate with points: 4.87%
The difference between the two interest rates is the value of one point.
Interest rate difference = 5.05% - 4.87% = 0.18%
To find the value of one point, we calculate 0.18% of the loan amount:
Value of one point = 0.18% * $137,000
Value of one point = 0.0018 * $137,000
Value of one point = $246.60
Now, to determine the cost of three points, we multiply the value of one point by three:
Cost of three points = $246.60 * 3
Cost of three points = $739.80
The price of three points for the homebuyers is therefore $739.80.

There are 120 ways in which 5 riders and 5 horses can be arranged.
We have,
5 riders and 5 horses,
Now,
We know that,
Now,
Using the arrangement formula of Permutation,
i.e.
The total number of ways \(^nN_r = \frac{n!}{(n-r)!}\),
So,
For n = 5,
And,
r = 5
As we have,
n = r,
So,
Now,
Using the above-mentioned formula of arrangement,
i.e.
The total number of ways \(^nN_r = \frac{n!}{(n-r)!}\),
Now,
Substituting values,
We get,
\(^5N_5 = \frac{5!}{(5-5)!}\)
We get,
The total number of ways of arrangement = 5! = 5 × 4 × 3 × 2 × 1 = 120,
So,
There are 120 ways to arrange horses for riders.
Hence we can say that there are 120 ways in which 5 riders and 5 horses can be arranged.

Find the length of side x in simplest radical form with a rational denominator
Answer:
(4\(\sqrt{3}\))/3
Step-by-step explanation:
From the diagram,
Applying
sinθ = Opposite/Hypotenuse................. Equation 1
From the diagram,
Given: θ = 60°, Opposite = 2, Hypotenuse = X
Substitute these values into equation 1
sin60° = 2/X
make X the subject of the equation
X = 2/sin60°.................. Equation 2
But,
sin60° = \(\frac{\sqrt{3} }{2}\)
Therefore,
X = 2/( \(\frac{\sqrt{3} }{2}\))
X = (2×2)/\(\sqrt{3}\)
X = 4/\(\sqrt{3}\)
Rationalising the denominator,
X = (4/\(\sqrt{3}\))×(\(\sqrt{3}\)/\(\sqrt{3}\))
X = (4\(\sqrt{3}\))/3

you cannot directly assign an enumerator to an int variable.
a. true b. false
Answer:
Step-by-step explanation:
True.
An enumerator is a special data type in some programming languages that allows us to give names to integer values, making the code more readable and easier to maintain.
However, an enumerator cannot be directly assigned to an int variable because they are not compatible data types. An int variable can only store integer values, while an enumerator is a named constant that represents an integer value.
To assign an enumerator to an int variable, we need to explicitly cast the enumerator to an int using type conversion.

do you remember how to find a discontinuity of a rational function? how is it different from an asymptote
the discontinuities of a rational function involves finding the values of x that make the denominator equal to zero, while finding the asymptotes of a rational function involves examining the behavior of the function as x approaches certain values.
Describe the function.
There will be questions on every subject, including created and real places as well as algebraic variable design, on the midterm test. a schematic illustrating the connections between various components that work together to produce the same outcome. A service is made up of many unique parts that work together to produce unique outcomes for each input.
To find the discontinuities of a rational function, we need to determine where the function is undefined. In general, a rational function is a function of the form:
f(x) = p(x) / q(x)
where p(x) and q(x) are polynomials in x, and q(x) is not the zero polynomial. The rational function f(x) is undefined at any value of x that makes the denominator q(x) equal to zero, since division by zero is undefined.
Therefore, to find the discontinuities of a rational function, we need to solve the equation q(x) = 0. The values of x that make q(x) equal to zero are called the "zeros" or "roots" of the denominator q(x). These values of x are the discontinuity points of the function, since the function is undefined at those points.
On the other hand, to find the asymptotes of a rational function, we need to examine the behavior of the function as x approaches certain values. In general, a rational function may have three types of asymptotes: horizontal, vertical, and oblique (also called slant).
Vertical asymptotes occur when the function approaches positive or negative infinity as x approaches a certain value, typically where the denominator q(x) equals zero.
Horizontal asymptotes occur when the function approaches a constant value as x approaches positive or negative infinity.
Oblique asymptotes occur when the degree of the numerator is exactly one greater than the degree of the denominator. In this case, the function approaches a straight line (i.e., a slant asymptote) as x approaches positive or negative infinity.
To summarize, finding the discontinuities of a rational function involves finding the values of x that make the denominator equal to zero, while finding the asymptotes of a rational function involves examining the behavior of the function as x approaches certain values.
