Conversion a mixed number 8 1/6 to a improper fraction: 8 1/6 = 8 1/ 6 = 8 · 6 + 1/ 6 = 48 + 1/ = 49/6 To find a new numerator: a) Multiply the whole number 8 by the denominator 6. Whole number 8 equally 8 * 6/6 = 48/6
b) Add the answer from the previous step 48 to the numerator 1. New numerator is 48 + 1 = 49
c) Write a previous answer (new numerator 49) over the denominator 6.
Eight and one sixth is forty-nine sixths
Conversion a mixed number 1 7/8 to a improper fraction: 1 7/8 = 1 7/8 = 1 · 8 + 7/8 = 8 + 7/8= 15/8 To find a new numerator:
a) Multiply the whole number 1 by the denominator 8. Whole number 1 equally 1 * 8/8 = 8/8 b) Add the answer from previous step 8 to the numerator 7. New numerator is 8 + 7 = 15
c) Write a previous answer (new numerator 15) over the denominator 8. One and seven eighths is fifteen eighthsDivide: 49/6: 15/8= 49/6· 8/15 = 49·\.8/6 · 15 = 392/90= 2 · 196/=2 · 45= 196/45 Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 15/8 is 8/15) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, cancel by a common factor of 2 gives 196/ 45. In other words - forty-nine sixths divided by fifteen eighths = one hundred ninety-six forty-fifths.

A quadratic function has these characteristics:
x = 1 is the equation for the axis of symmetry.
x = –1 is an x-intercept.
y = –4 is the minimum value.
Determine the y-intercept of this parabola.
Explain your thought process.
Answer:
The y-intercept would be between 0 and -4 likely about -3.
Step-by-step explanation:
The y-intercept would be between 0 and -4 likely about -3.
Since the parabola has an axis of symmetry at x = 1 and a minimum of y = -4 then the vertex is (1,-4).
It has an x-intercept at x = -1 or (-1,0). This means from the vertex up to the x-intercept the function has to cross through the y-axis. This makes the y-intercept between 0 and -4 and likely at -3.
The y-intercept of the quadratic function given above is found to be at y = -3. This conclusion is reached by analyzing the vertex, its symmetry, and x-intercepts of the function, and applying these properties in the standard form of a quadratic function.
Explanation:The subject of this question is the properties of a quadratic function in mathematics. The given characteristics provide us with enough information to determine the y-intercept of the function. Let's analyze the information.
Since the axis of symmetry is 'x = 1', we know that the vertex of the parabola is at (1, y). Also, because it has a minimum value of 'y = -4', we know the y-coordinate of the vertex is -4. Therefore, the vertex of the parabola is at (1, -4).
An x-intercept at 'x = -1' means that (-1, 0) is a point on the parabola. From the nature of the symmetry of parabolas, we know that if there is a point (a, 0) on the parabola, there will also be a point on the other side of the axis of symmetry at (2h-a, 0), where 'h' is the x-coordinate of the vertex. So, we can calculate the other x-intercept as (2*1 - (-1), 0), which gives us (3, 0). Thus, a point on the parabola is also (3, 0).
Equipped with the vertex (1, -4) and a point on the parabola (3,0), we can use the form of a quadratic function y = a(x-h)² + k to determine the quadratic function. Substituting coordinates of the vertex into the formula for h and k, and the coordinates of the point into the formula for x and y, we get 0 = a(3-1)² + (-4). From that, we can solve for 'a', which equals 1.
So, our quadratic function is y = (x-1)² - 4. To find the y-intercept (the point where the function crosses the y-axis, where x=0), we substitute x=0 into our function, which yields y = (0-1)² - 4 = -3.
The y-intercept of the parabola is at y = -3.

The smallest angle is R, so the smallest side is opposite it, which is PQ
From largest to smallest
RQ, RP, PQ
Answer:
The correct answer is option 2
RQ > PQ > RP
Step-by-step explanation:
From the figure we can see that, a triangle PQR.
Three angles are given.
The angles are, <P = 105°, <R = 40° and <Q = 35°
To find the order of sides
We know that, the side opposite to the largest angle is the largest side, So we can write the three sides are in ascending order,

help plz( If the shell of a bass drum was cut down one side and laid flat, which expression would give the area, A, of the shell with the measurements shown? )
Answer:
Last option: [tex]A=2\pi rh[/tex]
Step-by-step explanation:
If the shell of a bass drum was cut down one side and laid flat, the resulting shape would be a rectangle.
The area of a rectangle can be calculated with the formula:
[tex]A=l*w[/tex]
Where l is the lenght and w is the width.
In this case, the lenght of the rectangle obtained (the lenght of the shell) is the circumference of the drum.
Remember that the circumference of the circle can be calculated with:
[tex]C=2\pi r[/tex]
Where r is the radius of the circle.
Then:
[tex]l=2\pi r[/tex]
The width is the height of the shell:
[tex]w=h[/tex]
Then, substituting into [tex]A=l*w[/tex], you get:
[tex]A=2\pi rh[/tex]
Meghan counted the candies she had in a jar. She discovered that half of the candies were red. If she had 50 red candies, in which equation does x represent the total number candies in the jar?
50x2=x
50 represents the red candies.
2 represents the other half of candies.
x represents the total amount of candies.
Hope this helps!
The equation representing the total number of candies in Meghan's jar, where x is the total, is x/2 = 50, giving us 100 candies in total. For Jenny's chocolates, Jenny initially had 14 chocolates before she ate two and gave half of the remaining to Lisa.
If Meghan discovered that half of the candies were red and she had 50 red candies, then to find the equation representing the total number of candies in the jar, we assign x to represent the total number. Since half of x is 50, the equation is x/2 = 50. To find x, we multiply both sides of the equation by 2, resulting in x = 100. Therefore, Meghan has 100 candies in total in her jar.
To address the question about Jenny and her chocolates: Initially, Jenny has some number of chocolates. When she eats two chocolates and gives half of the remainder to Lisa, and Lisa ends up with six chocolates, we can determine how many Jenny started with. Lisa's six chocolates represent half of what remained after Jenny ate two, which implies there were 12 before giving to Lisa, and so initially, Jenny had 14 chocolates.

Line m is parallel to the y-axis, and its slope is _____.
positive
negative
undefined
0
The answer is Undefined
Answer:
undefined
Step-by-step explanation:
The y-axis is a vertical line.
The point [tex](0,y_1)[/tex] and[tex](0,y_2)[/tex] lies on the y-axis.
The slope of this line is
[tex]=\frac{y_2-y_1}{0-0}[/tex]
[tex]=\frac{y_2-y_1}{0}[/tex]
Division by zero is undefined.
All vertical lines have undefined slopes because they are parallel to the y-axis.
Therefore the slope of m is undefined.

Sonji paid $25.00 for two scarves, which were different prices. When she got home she could not find the receipt. She
remembered that one scarf cost $3 more than the other. What was the price of the more expensive scarf?
Answer:
$14
Step-by-step explanation:
Sony paid for two scarves = $ 25
We are given that one scarf cost $3 more than the other
Let the cost of one scarf be x
So, cost of another scarf = x+3
Since the total cost is $25
So, [tex]x+x+3=25[/tex]
[tex]2x+3=25[/tex]
[tex]2x=22[/tex]
[tex]x=\frac{22}{2}[/tex]
[tex]x=11[/tex]
So, cost of one scarf = $11
Cost of another scarf = x+3=11+3=14
Hence the cost of the expensive scarf is $14

The number of angles that are alternate exterior angles with angle 5 is equal to 1.
What are parallel lines?In Mathematics, parallel lines are two lines that are cut through by a transversal and they always have the same (equal) distance apart and never meet.
What is the alternate exterior angle theorem?In Mathematics, the alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed lie outside the two (2) parallel lines, are located on opposite sides of the transversal, and are congruent angles.
In conclusion, we can logically deduce that both m∠5 and m∠11 are alternate exterior angles because they lie outside the two (2) parallel lines and are located on opposite sides of the transversal.

Is the answer H, I, J, or K
H. infinitely many I. no solution J. (0,5) K. (5,0)
Answer:
I would be our answer.
Step-by-step explanation:
So we need to solve both.

And we also need to solve -x+y=5.
Let's regroup them.
[tex]y-x=5[/tex]
Now we needt to subtract y from both sides.
[tex]-x = 5 -y[/tex]
Now let's multiply both sides by -1.
[tex]x = -5 + y[/tex]
Then we finally get
x = y - 5

False. Correct equation: [tex]\(2n - 7 = -5\)[/tex]. Your proposed equation [tex]\(7 - 5n = -5\)[/tex] does not accurately represent the relationship.
The answer is False.
Here's why:
1. The statement "seven less than twice a number" can be represented as [tex]\( 2n - 7 \)[/tex], where [tex]\( n \)[/tex] is the number.
2. The equation for "seven less than twice a number is negative five" should be [tex]\( 2n - 7 = -5 \)[/tex], as the phrase "is negative five" translates to the equation being equal to [tex]\( -5 \)[/tex].
3. Your proposed equation, [tex]\( 7 - 5n = -5 \)[/tex], is incorrect because it represents a different relationship. It suggests that [tex]\( 7 \)[/tex] subtracted by [tex]\( 5n \)[/tex] is equal to [tex]\( -5 \)[/tex], which does not align with the given statement.
4. To correct the equation, simply rewrite it as [tex]\( 2n - 7 = -5 \)[/tex], which accurately represents the relationship described in the statement.
Therefore, the statement is false because the given equation does not correctly represent the phrase "seven less than twice a number is negative five."
