Answer:
(2/7)
Step-by-step explanation:
As far as I know, an absolute value number is never negative. So you would do |-26/91| which would give you the positive fraction of (2/7). I don't think the fraction could get any simpler than that.

The coordinate -8 has a weight of 3 and the coordinate 4 has a weight of 1. Find the weighted average
The weighted average is -5
The formula for the weighted average is
= Σwixi/Σwi (1)
Where wi = are the weights and
xi are the coordinates
We have been given that
w1 = 3 , x1 = -8 and w2 = 1 , x2 = 4
Σwixi = w1x1 + w2x2
= 3*-8 + 1*4
= -24 + 4
= -20
Σwi = w1 + w2
= 3 + 1
= 4
Now putting the required value in equation (1) we get
Weighted average = -20/4
= -5
Hence the weighted average is -5

the perimeter of a rectangle is 260cm the length is 50 less than its width. find its dimensions
The dimensions of the rectangle is found as: (b = 90 cm) and (l = 40 cm
).
What is defined as the perimeter of the rectangle?The perimeter (P) of such a rectangle has been the total length of all of its sides. A rectangle does have two equal lengths as well as two equal widths because its opposite sides are equal. The perimeter of a rectangle is calculated as follows: perimeter = length + length + width + widthLet 'l' be the length of the rectangle.
Let 'b' be the width of the rectangle.
then,
Perimeter = 2(l + b)
The given value of the perimeter = 260 cm.
The length is 50 less than the width.
Thus, l = b - 50.
Put the values in the formula;
260 = 2( b - 50 + b)
Simplify the equation;
260 = 4b - 100
4b = 360
b = 90 cm
Put the value of b in the length;
l = b - 50
l = 90 - 50
l = 40 cm
The dimension are estimated as; (l = 40 cm) and (b = 90 cm).

On the 4th day of the school, the secret Quinten shared with his closest friend will be known to 16 persons.
What is Geometric progression?
A sequence in which the ratio of any term and its previous term is equal to a fixed constant called common ratio [r] is called geometric progression. For example -
3, 6, 12, 24, ... and so on.
Given that Quinten shares a secret with his friend and each person that hears the secret shares the secret with a new person each day.
On the first day only 2 people know the secret i.e. Quinten and his close friend. Now, they both will tell one new person on second day, which means that by the end of second day four persons will know the secret. Now, these four persons will share with new individual, this gives us a total of 8 persons, who knows the secret by the end of day three and so on.
Now, we get the following sequence -
2, 4, 8, ...... and on.
Now, we can clearly see that -
4/2 = 8/4 = 2
Therefore, this sequence is a geometric progression with common ratio
r = 2.
Assume the 4th term of GP is x. Therefore -
x/8 = 2
x = 16
Therefore, on the 4th day of the school, the secret Quinten shared with his closest friend will be known to 16 persons.

What is meant by a circle's circumference?
The distance along a circle's perimeter is referred to as its circumference. In other words, the circumference of a circle is equal to the length of a straight line formed by opening up the circle.
connect O and B
∵ OB = OD
∴ ∠ OBD = ∠ODB = x°
∴ ∠BOD = 180° - 2x°
∵ ∠BAD = y°
∴ ∠C = 180° - y°
∠BOD = 2∠C
180° - 2x° = 2 ( 180 - y° )

A model train is on a track 100 cm from its starting point. turning a switch displaces the train either forward or backward 25 cm along the track depending on which way the switch is turned. which equation models the position of the train along the track after you turn the switch?
The equation which models the position of the train along the track can be given as |x − 100| = 25.
One-variable linear equation is defined as the equation which can be written in the form of ax+b = 0, where a and b are two integers, and x is a variable. One-variable linear equation has only one solution. For example, the linear equation 4x+2=14 only has one variable and only one solution.
The location of the train is given by the value of x. Therefore, if x was equal to the value 85, it would be at the position 85 on the number line.
The distance between x and distance of track that is 100 is given as |x-100|. The distance can never be negative, so we take the absolute value. Because the switch is switched after the train has traveled 25 cm in one direction, we need this distance to be 25 cm.
Therefore, the equation which models the position of the train along the track is represented by |x − 100| = 25.

A 6 inch personal pizza has 610 calories, with 240 of those from fat. A 16 inch pizza is cut into 8 slices. Estimate the number of calories in one slice of a 16 inch pizza.
Answer:
203 1/3 calories
Step-by-step explanation:
I make a proportion for inches of pizza to calories
[tex]\frac{6}{610}[/tex] = [tex]\frac{16}{x}[/tex] I know that a 6 inch pizza has 610 calories, so I am trying to figure out how many calories are in a 16 inch pizza.
I can cross multiply to get
6x = (16)(610)
6x = 9760 Divide both sides by 6
x = 1626 [tex]\frac{2}{3}[/tex] This is how many calories are in a whole pizza. Now I want to know how many calories are in 1 slice. I would take this number and divide by 8.
1626 2/3 as an improper fraction would be
[tex]\frac{4880}{3}[/tex] ÷ 8 Which is the same as

A polynomial is a form of algebraic expression wherein all variable exponents are whole numbers. Variable exponents in any polynomial must be non-negative integers.The degree of a polynomial is the highest as well as greatest exponent of a variable in a polynomial. Utilising Descartes' Rule of Signs, the degree is used to estimate the optimum number of solutions to a polynomial equation.For the given algebraic expression 8x;
As, the highest exponent of the variable part 'x' is 1 that is why the degree of the polynomial is one.
