The middle school dance team had 3 separate car washes on Saturday to raise money for new uniforms. The Main Street location raised $50 more than the Back Street location. The Washington Street location raised $50 more than half the amount raised at the Back Street location. How much did the dance team raise at each location if they raised a total of $600?
HELP PLEASE
The amount of money that each team raised are;
Amount raised by Back Street location = $200
Amount raised by Main Street location = $250
Amount raised by Washington Street = $150
How to Solve Algebra Word Problems?We are told that the main street location raised $50 more than the Back Street location. Thus;
m.s = b.s + 50 ------(eq 1)
The Washington Street location raised $50 more than half the amount raised at the Back Street location. Thus;
w.s = ¹/₂b.s + 50 -------(eq 2)
Total raised = $600. Thus;
m.s + b.s + ws = 600 -------(eq 3)
-----------------------------
Plug in b.s + 50 for m.s and ¹/₂b.s + 50 for w.s in eq 3 to get;
(b.s + 50) + (¹/₂b.s + 50) + b.s = 600
Solve for b.s;
b.s + ¹/₂b.s + b.s + 50 + 50 = 600
(5/2)b.s + 100 = 600
(5/2)b.s = 500
b.s = $200 (amount raised by Back Street location)
m.s = b.s + 50
= 200 + 50
= $250 (amount raised by Main Street location)
w.s = (1/2)b.s + 50
w.s = 100 + 50
w.s = $150 (amount raised by Washington Street)

Percentage of unemployment is 58.33 % in the total household of 60,000.
What is Percentage?Although the abbreviations "pct.", "pct.", and "pct." are also used, the percent symbol, "%," is most commonly used. A percentage is a number with no dimensions and no standard measurement.
The English word "percentage" is derived from the Latin phrase "per centum," which means "by the hundred." Percentages are fractions with a numerator of 100. In other words, it is a relationship in which the total value is always assumed to be one hundred.
Percentage calculation is the process of determining a percentage of a whole in terms of 100. There are two ways to calculate a percentage:
Using the unitary approach
by adjusting fraction's denominator to 100.
It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation isn't applied. In these situations, we employ the unitary technique.
Total number of household is 60000
Total number of household which is unemployed is 35000
Percentage of unemployment = (35000/60000) * 100 = 58.33 %

Explain why the range of f(x)=arcsin(x) is different than g(x)=arccos(x) .
The range of a function is the set of all possible output values of the function. The range of f(x) = arcsin(x) is different than the range of g(x) = arccos(x) because the domain of each function is different.
The function f(x) = arcsin(x) is the inverse sine function, and its domain is the set of all real numbers between -1 and 1, inclusive. This is because the sine function has a range of [-1,1], and the inverse sine function takes the input value from the range of sine function and gives the corresponding angle in radians. So the range of arcsin(x) is [-π/2, π/2]
On the other hand, the function g(x) = arccos(x) is the inverse cosine function, and its domain is the set of all real numbers between -1 and 1, inclusive. This is because the cosine function also has a range of [-1,1], and the inverse cosine function takes the input value from the range of cosine function and gives the corresponding angle in radians. The range of arccos(x) is [0, π]
So, in summary, the difference in the range of f(x) = arcsin(x) and g(x) = arccos(x) is due to the difference in the domain of each function.
Answer:
Ok this is going to be a bit confusing, and I may have-actually nevermind.
Step-by-step explanation:
The range of a function is the set of all possible output values that the function can produce. The range of f(x) = arcsin(x) is different than the range of g(x) = arccos(x) because the domain of the two functions is different.
The domain of f(x) = arcsin(x) is -1 <= x <= 1. This means that x can only take on values between -1 and 1 inclusive. The range of f(x) = arcsin(x) is -(pi/2) <= f(x) <= (pi/2). This is because the arcsine function maps the interval [-1, 1] onto the interval [-(pi/2), (pi/2)].
On the other hand, the domain of g(x) = arccos(x) is also -1 <= x <= 1, but the range of g(x) = arccos(x) is 0 <= f(x) <= pi. This is because the arccosine function maps the interval [-1, 1] onto the interval [0, pi].
Both functions are defined for the same values of x, but the range of arcsin(x) is between -(pi/2) and (pi/2) while the range of arccos(x) is between 0 and pi. This means that the range of arcsin(x) is a subset of the range of arccos(x).
Another way to see this is that the arcsin(x) and arccos(x) are inverse functions, meaning that arcsin(x) = y is equivalent to arccos(sin(y)) = x and arccos(x) = y is equivalent to arcsin(cos(y)) = x.
Therefore the range of arcsin(x) will be the set of all possible y such that -1 <= sin(y) <= 1 and the range of arccos(x) will be the set of all possible y such that -1 <= cos(y) <= 1.

Solve the system of equations below. Enter the value of the y value from your solution (in the case of a fraction or decimal solution, round your answer to the nearest tenth).
According to your solution of the given system of equations, the value of y is 7.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given a system of equation y = 2x + 11 and 3x + 2y = 8
From equation 1 we will substitute the value of y in the form of x in equation 2
=> 3x + 2(2x + 11) = 8
=> 3x + 4x + 22 = 8
=> 7x = 8 - 22
=> 7x = -14
=> x = -2
Substitute this value in equation 1
=> y = 2* -2 +11
=> y = -4 + 11

What is a circle:A circle is a closed polygon and a two-dimensional object where every point in the plane is equally spaced from a central point. Examples are rings, discs, wheels, bangles, coins, etc.
In a circle angle at the center will always equal 360°. There is a number of circular items that we can observe in the real world.
Here we have
(x²)°, 10x°, and (5x+36)° angles made by 3 sectors in a circle
As we know the sum of the angles at the center of a circle = 360°
=> x² + 10x + 5x+36 = 360
=> x² + 15x +36 = 360
=> x² + 15x - 324 = 0
Now factorize the above equation for the 'x' value
=> x² + 27x - 12x - 324 = 0
=> x(x + 27) - 12(x + 27) = 0
=> (x + 27) (x - 12) = 0

A container of bead contain8 redbead, 7 yellow bead , and green bead. A bead will be drawn from the baket and replace 60 time what i a reaonable prediction for the number of time green or red bead i drawn
A reasonable prediction for the number of times a green or red bead will be drawn from the container of beads, after being replaced 60 times, would be 42.
A reasonable prediction for the number of times a green or red bead will be drawn from the container of beads, after being replaced 60 times, would be close to the proportion of green or red beads in the container. The container has 8 red beads and 6 green beads out of a total of 8 + 7 + 6 = 21 beads. The proportion of green or red beads is (8 + 6) / 21 = 14/21.
We can use this proportion to predict the number of times a green or red bead will be drawn from the container. By multiplying the proportion of green or red beads by the number of times the bead is replaced, we get (14/21) * 60 = 42.
In this scenario, we are using the concept of probability and proportion. The probability of drawing a green or red bead is 14/21, and by multiplying it by the number of trials (60), we get the expected number of times the green or red bead will be drawn. This concept is used in statistics and probability to make predictions based on the available data. It is important to note that this is only a prediction and actual results may vary.

a. ( 3, 4 )
b. ( -5, 2 )
c. ( 6,- 7)
d. ( 5,- 2)
Answer:
answer is (d) (5, -2)
Step-by-step explanation:
When a triangle is translated, each point is moved the same distance in the same direction. To translate a point right, we add the amount of units to the x-coordinate, and to translate it down, we subtract the amount of units from the y-coordinate.
So for point A, the original coordinates are (1,5) and it is translated right 4 and down 7. The new coordinates of point A' will be (1+4, 5-7) = (5,-2)

A scatter plot was made with a trend line that had an equation of y = -0.25x + 85, where y is the total number of cases of the flu and x is the total number of students who recieved the flu vaccine.
Predict how many students received a flu vaccine if a school had 65 cases of the flu.
Answer:
80 students
Step-by-step explanation:
To predict the number of students who received a flu vaccine if a school had 65 cases of the flu, we would substitute 65 for y in the equation of the trend line: y = -0.25x + 85.
y = -0.25x + 85
65 = -0.25x + 85
then we solve for x by isolating it on one side:
x = (y - 85) / -0.25
x = (65 - 85) / -0.25
x = -20 / -0.25
x = 80
So, if a school had 65 cases of the flu, it is predicted that 80 students received the flu vaccine.
