What is the value of y 79° And 37
The value of y is 64°
Solution:
The image of the question is attached below.
Given two angles of a triangle.
One angle is 79°.
Other angle is 37°.
Let the unknown angle be y.
Triangle sum property:
Sum of all the angles of a triangle = 180°
⇒ y + 79° + 37° = 180°
⇒ y + 116° = 180°
⇒ y = 180° – 116°
⇒ y = 64°
Hence the value of y is 64°.
A parallelogram has one angle that measures 120°. What are the measures One of three angles in a parallelogram?
Answer:
60 degrees
Step-by-step explanation:
First we need to know how many degrees are in a parallelogram. We can use the formula 180(n-2) (n is the number of sides)
This works out to 180(4-2)=360 degrees.
Now we can set up the following equation as:
2(120)+2x=360 Subtract 240 from both sides to get:
2x=120 Divide by 2 to get:
x=60 degrees
Therefore we know 2 angles are each 120 degrees and the other 2 are 60 degrees.

Which quadratic function is represented by the graph?
Of(x) = 0.5(x + 3)(x - 1)
f(x) = 0.5(x - 3)(x + 1)
f(x) = 2(x + 3)(x - 1)
f(x) = 2(x - 3)(x + 1)
The correct quadratic function represented by the graph is [tex]\(f(x) = 0.5(x + 1)^2 - 2\)[/tex], and doesn't match with any of the options provided.
To find the quadratic function represented by the given graph, we first identify the vertex and then use it to determine the coefficient [tex]\(a\)[/tex] in the quadratic function.
1. Vertex Calculation:
- The x-coordinate of the vertex, [tex]\(h\)[/tex], is the average of the x-intercepts: [tex]\(h = \frac{1 + (-3)}{2} = -1\).[/tex]
- Since the focus lies 2 units below the vertex, [tex]\(k = -2\).[/tex]
2. Vertex Form of the Quadratic Function:
The vertex form is [tex]\(f(x) = a(x - h)^2 + k\)[/tex], where [tex]\((h, k)\)[/tex] is the vertex.
Substituting [tex]\(h = -1\) and \(k = -2\)[/tex], we get [tex]\(f(x) = a(x + 1)^2 - 2\).[/tex]
3. Determine [tex]\(a\):[/tex]
Using the x-intercept (1, 0):
[tex]\[0 = a(1 + 1)^2 - 2\][/tex]
[tex]\[0 = 4a - 2\][/tex]
[tex]\[4a = 2\][/tex]
[tex]\[a = \frac{1}{2}\][/tex]
4. Quadratic Function:
Substitute [tex]\(a = \frac{1}{2}\)[/tex] into the vertex form:
[tex]\[f(x) = \frac{1}{2}(x + 1)^2 - 2\][/tex]
Therefore, the correct quadratic function represented by the graph is [tex]\(f(x) = 0.5(x + 1)^2 - 2\).[/tex]
The question probable maybe:
Which quadratic function is represented by the graph?
f(x) = 0.5(x + 3)(x - 1)
f(x) = 0.5(x - 3)(x + 1)
f(x) = 2(x + 3)(x - 1)
f(x) = 2(x - 3)(x + 1)

Unemployment is the ratio of
A. unemployed workers to employed workers
B. unemployed workers to total workers
C. workers to total population
D. workers to nonworkers
Answer:
C. Workers to total population.
Unemployment is defined as the condition of people who are able to work but cannot find jobs. The unemployment ratio is most accurately described by option B: 'unemployed workers to total workers'. This does not include people who are not part of the labor force.
Explanation:Unemployment is defined as the condition in which people who are able and willing to work cannot find jobs. In terms of the provided options, unemployment is best defined by option B: 'unemployed workers to total workers'. This is because the unemployment rate is calculated by dividing the number of unemployed individuals by the total number of individuals in the labor force (which includes both the employed and the unemployed) and then multiplying by 100 to get a percentage.
This measure gives a good representation of the number of people who are jobless compared to the overall amount of people who are either working or actively seeking work. It's important to keep in mind that it doesn't include people who are not part of the labor force, like children, retirees, and others who are not looking for work.

it to find for how many hours the total cost of the services is equal, Use the
variable h to represent the number of hours,
Answer:
8.8 hours
Step-by-step explanation:
Given: Happy Paws charges $20.00 plus $2.50 per hour to keep a dog.
Woof Watchers charges $9.00 plus $3.75 per hour.
Lets assume the number of hours service provided be "h".
First, writing an equation for Happy paws cost for service.
Total cost of service= [tex]\$ 2.5\times h+ \$ 20[/tex]--- equation 1
Second, writing an equation for Woof watchers cost of services.
Total cost of service= [tex]\$ 3.75\times h+ \$9[/tex]--- equation 2
Now, finding number of hours services provided, when cost of service will be equal for both service provider.
∴ [tex]2.5h+ 20= 3.75h+ 9[/tex]
Solving the equation now to find number of hour.
⇒ [tex]2.5h+ 20= 3.75h+ 9[/tex]
Subtracting both side by 2.5h
⇒ [tex]20= 3.75h+ 9-2.5h[/tex]
Subtracting both side by 9
⇒ [tex]1.25h= 11[/tex]
Dividing both side by 1.25
⇒[tex]h= \frac{11}{1,25}[/tex]
∴[tex]h= 8.8\ hours[/tex]
Hence, 8.8 hours is the number of hours when cost of service will be equal for both service provider.

lim x-1 x2 - 1/ sin(x-2)
Answer:
[tex]\lim_{x \to 1}\frac{x^2-1}{sin(x-2)}=0[/tex]
Explanation:
Assuming the correct expression is to find the following limit:
[tex]\lim_{x \to 1}\frac{x^2-1}{sin(x-2)}[/tex]
Use the property the limit of the quotient is the quotient of the limits:
[tex]\lim_{x \to 1}\frac{x^2-1}{sin(x-2)}=\frac{\lim_{x \to 1}x^2-1}{\lim_{x \to 1}sin(x-2)}[/tex]
Evaluate the numerator:
[tex]\frac{\lim_{x \to 1}x^2-1}{\lim_{x \to 1}sin(x-2)}=\frac{1^2-1}{\lim_{x \to1}sin(x-2)}=\frac{0}{\lim_{x \to 1}sin(x-2}[/tex]
Evaluate the denominator:
Since [tex]\lim_{x \to1}sin(x-2)\neq 0[/tex][tex]\frac{0}{\lim_{x \to1}sin(x-2)}=0[/tex]
One number is 5 more than the other. Their sum is 33. Find the numbers.
Final answer:
The two numbers are 14 and 19, where one number is 5 more than the other and their sum is 33.
Explanation:
To find the two numbers where one number is 5 more than the other and their sum is 33, we can set up a system of equations. Let's call the first number x, which means the second number would be x + 5 since it's 5 more than the first. Their sum is given as 33, so we can create the following equation:
x + (x + 5) = 33
Now we simplify the equation:
2x + 5 = 33
To solve for x, we subtract 5 from both sides:
2x = 33 - 5
2x = 28
Finally, we divide both sides by 2 to find the value of x:
x = 28 / 2
x = 14
Now that we have the first number, we can easily find the second number by adding 5:
The second number is x + 5 = 14 + 5 = 19.
The two numbers are 14 and 19.

Mrs. Morales wrote a test with 19 questions covering spelling and vocabulary. Spelling questions (x) are worth 5 points and vocabulary questions (y) are worth 10 points. The maximum number of points possible on the test is 100.
Part 1 out of 4
Write an equation in slope-intercept form to represent the number of questions on the test.
The equation is .
Answer:
# of questions : y = -x + 19
Step-by-step explanation:
if ur only wanting the equation for the number of questions on the test, then it would be : x + y = 19......y = -x + 19 in slope intercept form.
and if u were wanting the number of points, then it would be :
5x + 10y = 100.....10y = -5x + 100.....y = -1/2x + 10. in slope intercept form
To express the number of questions on Mrs. Morales' test in slope-intercept form, first write the total point equation 5x + 10y = 100, then simplify and solve for y to get the slope-intercept form y = -0.5x + 10.
Explanation:To write an equation representing the number of questions on Mrs. Morales' test, we must consider the total points possible and the value of each question type. The spelling questions (x) are 5 points each, and the vocabulary questions (y) are 10 points each. The total points for the test are 100, which leads us to the equation 5x + 10y = 100.
However, to put this into slope-intercept form, we solve for y. Dividing the entire equation by 10 gives us 0.5x + y = 10. Then, isolating y yields y = -0.5x + 10, which is now in slope-intercept form where the slope (m) is -0.5 and the y-intercept (b) is 10.
The slope-intercept form provides a way to see how many vocabulary questions (y) can be on the test for a given number of spelling questions (x).

The solution of the inequality is h > -3 ⇒ 2nd answer
Step-by-step explanation:
Let us revise very important notes about solving inequalities
You can add and subtract both sides of inequality by a number without change the sign of inequalityYou can multiply or divide both sides of inequality by a positive number without change the sign of inequalityYou can multiply or divide both sides of inequality by a negative number with change the sign of inequality (-2x < 4 ⇒ ÷ (-2) makes it x > -2)∵ -4 h - 3 < 9
- Start with adding both sides by 3 to separate the variable
in one side and the numerical term in the other side of the
inequality sign
∴ -4 h - 3 + 3 < 9 + 3
∴ -4 h < 12
- Now divide both sides by -4 and use the last note above
∵ -4 ÷ -4 = 1
∵ 12 ÷ -4 = -3
∵ < must change to > (because we divide both sides by (-) number
