A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
First, we need to solve for a common denominator.
What is a common denominator?A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.
To get the common denominator between [tex]\frac{18}{7}[/tex] and [tex]\frac{5}{6}[/tex], we multiply their denominators.
7 × 6 = 42Now, we know the fractions would look like this:
[tex]\frac{?}{42} \frac{?}{42}[/tex]To solve for the numerators, we can use these equations:
18 × 6 = 1085 × 7 = 35Now, the fractions look like this:
[tex]\frac{108}{42}[/tex] and [tex]\frac{35}{42}[/tex]Adding them together:
[tex]\frac{108}{42} +\frac{35}{42} = \frac{143}{42}[/tex]Now, we can convert this into a mixed number.
[tex]\frac{143}{42} = 3\frac{17}{42}[/tex]Now that we have this, we can subtract that from 6 to get the missing value.
[tex]6 - 3\frac{17}{42}[/tex][tex]=2\frac{25}{42}[/tex]Therefore, the third fraction is [tex]2\frac{25}{42}[/tex].

in each part, determine the fundamental group up to isomorphism by showing it is homotopy equivalent to a space whose fundamental group is already known. which of the spaces are contractible?
If a map f:X→Y between connected CW complexes induces isomorphisms f∗:πn(X)→πn(Y) for all n, then f is a homotopy equivalence. In case f
is the inclusion of a subcomplex X↪Y , the conclusion is stronger: X is a deformation retract of Y.
A fairly generic notion called isomorphism can be found in many branches of mathematics. The word is derived from the Greek words morphosis, which means "to form" or "to shape," and iso, which means "equal." An isomorphism is a bijective morphism in formal terms. An isomorphism, as used informally, is a map that maintains sets and relationships between elements.

Step-by-step explanation:
If someone ate 3 out of 5 bagels, then there are 5 - 3 = 2 bagels left.
To find the percentage of the bagels that are left, you need to divide the number of bagels left by the total number of bagels and multiply by 100.
So, the percentage of the bagels that are left is (2 / 5) * 100 = 40%.
Suppose a is nn and the equation ax0 has only the trivial solution. Explain why a has n pivot columns and a is row equivalent to
The equation Ax = 0 has no free variables, so A has n pivot columns. Since A is square, the pivots must be on the main diagonal, so A is row equivalent to the n x n identity matrix Iₙ.
In order for the equation Ax = 0 to have only the trivial solution, there must be no free variables. This means that the matrix A must have n pivot columns. Since A is square, the n pivot positions must be in different rows, which means that the pivots must be on the main diagonal. This means that A is row equivalent to the n x n identity matrix Iₙ. To make it row equivalent, we can perform elementary row operations, such as adding or subtracting rows, or multiplying or dividing a row by a non-zero constant. Once we have done this, the matrix will be in echelon form and the main diagonal will be composed of all 1s. This means that A is row equivalent to Iₙ.
The complete question: Suppose A is nˣn and the equation Ax=0 has only the trivial solution. Explain why A has n pivot columns and A is row equivalent to Iₙ
Choose the correct answer below.
A. Suppose A is nˣn and the equation Ax = 0 has only the trivial solution. Then there are no free variables in this equation, thus A has n pivot columns. Since A is square and the n pivot positions must be in different rows, the pivots in an echelon form of A must be on the main diagonal. Hence A is row equivalent to the nˣn identity matrix, Iₙ.
B. Suppose A is nˣn and the equation Ax = 0 has only the trivial solution. Then there are no free variables in this equation, thus A has n pivot columns. Since A is square and the n pivot positions must be in different rows, the pivots in A must be on the main diagonal. Hence A is the nˣn identity matrix, Iₙ.
C. Suppose A is nˣn and the equation Ax=0 has only the trivial solution. Then there are n free variables in this equation, thus A has n pivot columns.

A farmer takes 250 chickens to be sold at a market. In the first hour he sells 8% of his chickens. In the second hour he sells 10% of those that were left. What percentage of the original number did he manage to sell in the two hours?
Answer:
17.2%
Step-by-step explanation:
In the first hour:
The farmer sells 8% of the total chickens:
[tex]= \frac{8}{100}[/tex]×[tex]250[/tex]
= 20 chickens
Therefore, the number of chickens left are:
= (250 - 20) chickens
= 230 chickens
In the second hour:
The farmer sells 10% of the chickens left:
= [tex]\frac{10}{100}[/tex]×[tex]230[/tex]
= 23 chicken
∴ The total number of chickens sold in the two hours = (20 + 23) chickens
= 43 chickens
43 has to be expressed as a percentage of the original number (i.e. 250)
Percentage = [tex]\frac{Number Of Chickens Sold}{Total Number Of Chickens}[/tex]×[tex]100[/tex]%
= [tex]\frac{43}{250}[/tex]×[tex]100[/tex]%

A rocket is launched in the air. Its height in feet is given by h(t)= -16t^2+88t where t represents the time in seconds after launch. How long is the rocket in the air?
Answer: ___ seconds
For the given height function h(t)= -16t²+88t the rocket is in the air for 5.5 seconds.
Height of the launched rocket is equal to :
h(t)= -16t²+88t
Time is represented by 't' in seconds after launch
'h' represents the height of the rocket.
For how long time rocket is in the air :
h(t) = 0
⇒ -16t²+88t = 0
⇒ t ( -16t+88 ) = 0
⇒ t = 0 or ( -16t+88 ) = 0
value of time 't' cannot be equal to zero.
This implies ( -16t+88 ) = 0
⇒16t = 88
⇒ t = 88 / 16
⇒ t = 5.5 seconds
Therefore, the time for which rocket is in the air as per given height function is equal to 5.5 seconds.

The graph of the system has been attached below. The solution has been obtained by using linear inequality.
What is linear inequality?
If the equals relation were used in its place, a linear inequality would produce a linear equation.
We are given two inequalities as x+y < 1 and 5x + y > 4
For plotting the points, we need to find x and y
1. x+y < 1
So, let y be 0, then
⇒x < 1
This gives us the point as (1,0).
Now, let x=0, then
⇒y < 1
This gives us the point as (0,1).
From these two points, the graph for the inequality is drawn and represented by red line.
2. 5x + y > 4
So, let y be -1, then
⇒5x > 5
⇒x > 1
This gives us the point as (1,-1).
Now, let x=0, then
⇒y > 4
This gives us the point as (0,4).
From these two points, the graph for the inequality is drawn and represented by green line.

Lauren has a coin collection. She keeps 3 of the coins in her box, which is 4% of the collection. How many total coins are in her collection?
The total coins in Lauren's coin collection = 75
Let us assume that there are 'n' total coins in Lauren's coin collection.
She keeps 3 of the coins in her box, which is 4% of the collection.
This means that 4 percent of 'n' is equal to 3.
Using the percentage formula,
4 % of m = 3
m × (4/100) = 3
We solve above equation for m.
⇒ m × 4 = 3 × 100 ..........(multiply both the sides by 100)
⇒ m × 4 = 300
⇒ m = 300/4 ..........(divide both the sides by 4)
⇒ m = 75

To find f(2) using synthetic division, we set up the synthetic division table with the coefficients of the polynomial:
What is synthetic division?Synthetic division is a shorthand method of dividing a polynomial by a linear factor of the form (x - a), where a is a constant. The method is used to simplify the long division process and is particularly useful for finding the roots of a polynomial.The basic idea behind synthetic division is to use the coefficients of the polynomial and the constant a to create a condensed division table that eliminates the need for writing out all the intermediate steps of the division process.2 │ 5 -13 4 -2
│ 10 -6 -2
└───────────
5 -3 -2 0
The last entry in the bottom row of the table gives the remainder of the division, which is f(2). Therefore, we have:
f(2) = 5(2)³ - 13(2)² + 4(2) - 2 = 40 - 52 + 8 - 2 = -6
So, the value of the function f(x) = 5x³-13x² + 4x-2 at x = 2 is f(2) = -6.

Put the equation in
slope-intercept form.
y - 4x = 17
y = 4x + [?]
Enter
Answer: To put the equation y - 4x = 17 in slope-intercept form, we need to isolate the y variable on one side of the equation and have the coefficient of x be the slope of the line and the constant term be the y-intercept.
Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.
Starting with the equation y - 4x = 17, we can isolate y by adding 4x to both sides:
y - 4x + 4x = 17 + 4x
y = 4x + 17
So, the equation in slope-intercept form is y = 4x + 17, where the slope (m) is 4 and the y-intercept (b) is 17.
Step-by-step explanation:
y-4x = 17
slope intercept= y= 4x + 17

Answer:
∠ABC = 115∘
Step-by-step explanation:
∠ABC = 1/2 ∠AOC
(Angle subtended by a chord on major area is half of that subtended on center)
∴ ∠ABC = 1/2 x 130 = 65
ABCD is a cyclic quadrilateral
Sum of opposite angles = 180∘
∴ ∠ABC + ∠AOC = 180∘
∠ABC + 65 = 180∘
