Rewrite the equation by completing the square.
x² + 4x = 0
Answer:
(x+2)^2 = 4
Step-by-step explanation:
x² + 4x = 0
Take the coefficient of the x term
4
Divide by 2
4/2 =2
Square it
2^2 =4
Add this to each side
x^2+4x+4 = 0+4
(x+4/2)^2 = 4
(x+2)^2 = 4

Of the 24,400 working hours logged at a beauty salon last year, Beatrice worked 976 hours. What percentage of the total hours did Beatrice work?
Answer: 4% (or 4.1% when rounded to the nearest tenth or 4.08 % when rounded to the nearest hundredth)
Step-by-step explanation:
First, you would need to put it into a fraction.
You have [tex]\frac{996}{24400}[/tex].
When you divided it, you would get:
0.04081....
Then you have to multiply times 100 to get it into percent form. This gives you:
4.081%
Then, round as you please!

Which number is an irrational number?
Answer:
0.6
Step-by-step explanation:
The sum of three numbers is -39.22. One of the numbers is 22.8. The other two numbers are equal to each other. What is the value of the other two numbers?
Answer:
The value of the other two numbers is 31.01
Step-by-step explanation:
Let the two numbers equal to each other be x
One of the numbers is 22.8
The sum of three numbers is -39.22.
So, x+x+22.8=-39.22
2x+22.8=-39.22
2x=-39.22-22.8
2x=-62.02
[tex]x=\frac{-62.02}{2}[/tex]
x=-31.01
Hence the value of the other two numbers is 31.01

Answer:
0.01 or 1%
Step-by-step explanation:
Find the original value of the stock by adding the amount lost to the end value.
$67.32 + $0.68 = $68.00
You would then divide the end value by the original value.
$67.32 / $68.00 = 0.99
To find what percentage the stock declined by, you would subtract.
1.00 - 0.99 = 0.01
To convert 0.01 to a percentage, you would multiply it · 100 to get 1%.

Which graph represents the equation y = --3x – 1?
Answer:
Step-by-step explanation:
The equation y = -3x - 1 represents a straight line with a slope of -3 and y-intercept of -1. The graph will be a line falling to the right and crossing the y-axis at -1.
Explanation:The question asks which graph represents the equation y = -3x - 1. This is a linear equation, where the coefficient of 'x', -3 here, gives us the slope of the line, and the constant, -1 here, gives us the y-intercept. A slope of -3 means for each step of 1 increase in x, the value of y decreases by 3. The y-intercept is the point where the line intersects with the y-axis, in this case at y = -1.
A graph representing this equation will be a straight line with a slope of -3 (indicating the line falls as we move along the positive x-axis) and will cut the y-axis at y = -1.

Can you subtract closed polynomials
Answer:
Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials.

which box plot represents a data set with a lower quartile or 24 and an upper quartile of 42
The box plot that represents a data set with a lower quartile of 24 and an upper quartile of 42 from the given option is D(The bottom option on the right end).
What are quartiles?When we get data that can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.
Quartiles are then selected as 3 points such that they create four groups in the data, each group approximately possessing 25% of the data.
The lower quartile, also called the first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.Similarly, the second quartile (also called median) is approximately in mid of the data.The third quartile (also called the upper quartile) has approx 75% in its left partition, and on its right lies approx 25% of the data.Left to right is said in the assumption that data were arranged increasingly from left to right
Since we need to find the box plot that has a lower quartile of 24 and an upper quartile of 42, therefore, we need to find a box plot whose rectangle starts at 24 and ends at 42, from left to right.
Hence, the box plot that represents a data set with a lower quartile of 24 and an upper quartile of 42 from the given option is D(The bottom option on the right end).

Consider the equation, 3x+4y=12.
Write the equation in slope-intercept form.
Identify the y-intercept.
Identify the slope.
The equation in slope-intercept form is y = -3x/4 + 3.
The y-intercept is 3.
The slope is -3/4.
What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
m is the slope or rate of change.x and y are the points.b is the y-intercept or initial value.Based on the information provided about this line, a linear equation that models it is given by;
y = mx + b
3x + 4y = 12
By making y the subject of formula, we have the following:
4y = -3x + 12
4y/4 = -3x/4 + 12/4
y = -3x/4 + 3
Therefore, the y-intercept is 3 and the slope is -3/4.

A motorboat travels 9 miles downstream (with the current) in 30 minutes. The return trip upstream (against the current) takes 90 minutesWhich system of equations can be used to find x, the speed of the boat in miles per hour, and y, the speed of the current in miles per hour? Recall the formula d = rt..
Answer:
Option B
Step-by-step explanation:
When moving with the current, the speeds of the boat and current will add up. The first situation can then be represented by:
9 = 0.5(x + y)
While opposing the current, the speeds will be subtracted. Forming:
9 = 1.5(x - y)
The second option contains this equation system, so it is correct.

Mrs. Henson's rectangular afghan is 2 feet
longer than it is wide. If the afghan has an
area of 24 square feet, what is its width?
(Remember, the area of a rectangle is its
length times its width.)
Answer:
The width is 4
Step-by-step explanation:
If the length is 6 feet, minus 2 will be 4. Six times 4 is 24, which is the area of the afghan rug. We are multiplying 6 and 4 because it is length times width in rectangle area.
Mrs. Henson's rectangular afghan width will be 4 feet
Area of a rectangleIt is the product of its length and width
How to solve this problem?
Let, x be width of rectangular afghanGiven,Length of afghan is 2 feet more than its width
∴ l = x+2
Area of rectangular afghan = 24 square feet
Now,Area of rectangular afghan = lw
[tex]24=x(x+2)\\24=x^{2} +2x\\x^{2} +2x-24=0\\x^{2} -4x+6x-24=0\\(x-4)(x+6)=0\\x=4 or -6[/tex]

One side of a rectangle is three times the other. Find the longer side if the perimeter is
29
Answer:
Answer: 10.875
Step-by-step explanation:
Let the short side be x.
Then the long side is 3x.
There are two opposite sides of each length, so the perimeter is
3x + 3x + x + x = 8x
The perimeter is 29, so we get the equation
8x = 29
Solve for x by dividing both sides by 8.
x = 29/8
x = 3.625
The longer side is 3x.
3x = 3(3.625) = 10.875
Answer: 10.875
Answer:
Answer:10.875
Step-by-step explanation:
Let the short side be x.
Then the long side is 3x.
There are two opposite sides of each length, so the perimeter is
3x + 3x + x + x = 8x
The perimeter is 29, so we get the equation
8x = 29
Solve for x by dividing both sides by 8.
x = 29/8
x = 3.625
The longer side is 3x.
3x = 3(3.625) = 10.875

4. If a student is chosen at random from

what is the probability that the student
participates in school sports, given that
the student is a male?
Answer choices:
0.379
0.476
0.524
0.621
Answer:
0.524
Step-by-step explanation:
To find the probability that a student participates in school sports given that the student is a male, we use conditional probability. The probability is approximately 0.624.
Explanation:To find the probability that a student participates in school sports given that the student is a male, we need to use conditional probability. Conditional probability is calculated by dividing the probability of two events happening together by the probability of the given condition.
Let's denote the event of a student participating in school sports as A and the event of a student being a male as B.
The probability of a student participating in school sports and being a male is given as 0.409. The probability of a student being a male is given as 0.654. Therefore, the conditional probability of a student participating in school sports given that the student is a male can be calculated as:
P(A|B) = P(A and B) / P(B)
P(A|B) = 0.409 / 0.654 ≈ 0.624
So, the probability that a student participating in the survey participates in school sports, given that the student is a male, is approximately 0.624.
