Ava and Wyatt are reading the same book. At the beginning of the month, Ava was on
page 10 and Wyatt was on page 30. Ava will read 20 pages per day and Wyatt will
read 15 pages per day. Let A represent the page of the book that Ava is on at the end
of t days into the month, and let W represent the page of the book that Wyatt is on at
the end of t days into the month. Graph each function and determine after how many

Ava and Wyatt will take 4 days to be on the same page of the book.
X-values must be chosen and entered into the equation in order to graph a function. You will obtain a y-value once those values have been entered into the equation. A single point's coordinates are made up of its x and y values.
From the given question we can get:
A = 10 ₊ 20t
W = 30 ₊ 15t
Graph the each function to get the number of days.
A function can only be graphed if X-values are selected and put into the equation. Once those values are introduced into the equation, a y-value will be produced. The values of x and y are the coordinates of a single point.
Hence we get the number of days as 4. and the graph is attached below.

Figure B is a dilated image of figure A. What is the scale factor?
A number raised to the fifth power.
proof let a be a square matrix of order n. (a)show that is symmetric. (b)show that is skew-symmetric. (c)prove that a can be written as the sum of a symmetric matrix b and a skew-symmetric matrix c, a
(a)Symmetric matrix -
Let matrix A be of order 3×3 =
[tex]\left[\begin{array}{ccc}1&3&8\\3&8&-4\\8&-4&6\end{array}\right][/tex]
So, the transpose of A will be -
A' =
[tex]\left[\begin{array}{ccc}1&3&8\\3&8&-4\\8&-4&6\end{array}\right][/tex]
So, we can say that A=A'. So, it is symmetric.
(b) Skew - symmetric matrix -
Let us consider a matrix B =
[tex]\left[\begin{array}{ccc}0&-6&4\\-6&0&7\\4&7&0\end{array}\right][/tex]
matrix B is said to be skew-symmetric if aij =−aji.
(B' =−B)
B' =
[tex]\left[\begin{array}{ccc}0&6&-4\\6&0&-7\\-4&-7&0\end{array}\right][/tex]
(c) A + A′ is a symmetric matrix for any square matrix A with real number entries, whereas A - A′ is a skew-symmetric matrix.
Proof: If B = A + A', then B ′ = (A + A ) ′
(A + B)′ = A′ + B′, thus = A′ + (A′)′
(as (A′)′ =A) = A′ + A
= B (because B + A = B + A′)
B = A+A′ is a symmetric matrix as a result.
Let C now equal A-A′.
Why does C' equal (A-A′)′=(A′)′?
= A′ - A (Why?)
=- (A - A′) = - C
A - A′ is a skew-symmetric matrix as a result.

The dog runs at 12 meters per second and the cat runs at 10 meters per second. Which does the dog reach first, the car or the end of the chain?
Answer: End of chain
Step-by-step explanation:
Dog is at pole and cat is at 8 meters if the dog runs at 12 meters a sec and cat runs at 10 in 2 secs the dog will reach end of chain. But the dog needs 4 secs to reach cat because the dog runs 2 meters a second faster than the cat. Hope it Helps!

Members of a sports club are junior, adult
or senior.
80 of these members were asked whether
they prefer tea, coffee or hot chocolate.
25 members are senior, of which 13
prefer coffee.
10 juniors prefer tea.
There are no adult members who prefer
hot chocolate.
2 out of the 18 juniors prefer coffee.
4 out of the 28 members who prefer tea
are seniors.
What fraction of members in the club
prefer hot chocolate?
Give your answer as a fraction in its
simplest form.
Fraction of members in the club that prefer hot chocolate = [tex]\frac{7}{40}[/tex]
It's Given that :
A sports club has 80 participants.
Senior Members = 25
Junior Members = 18
Adult Members = 80 - (25 + 18) = 80 - 43 = 37
JUNIOR MEMBERS :
Prefers tea = 10
Prefers Coffee = 2
Prefers hot chocolate = 18 - (10 + 2) = 18 - 12 = 6
SENIOR MEMBERS :
Prefers tea = 4
Prefers coffee = 13
Prefers hot chocolate = 25 - (4 + 13) = 25 - 17 = 8
ADULT MEMBERS :
Prefers tea = 28 - (10 + 4) = 28 - 14 = 14
Prefers coffee = 37 - 14 = 23
Prefers hot chocolate = 0 (none)
Calculation of Fraction of members in the club that prefer hot chocolate = 8 + 6 = 14 members out of 80 members
= [tex]\frac{14}{80} = \frac{7}{40}[/tex]
Therefore 7 / 40 of members prefer hot chocolate.

The vertices of ABCDE are A(-6, 0), B(-3, 0), C(0, -3), D(-3, -6), and E(-6, -3). Find the vertices
of the image after a translation using the rule (x,y) → (x + 9, y - 6) and a dilation with a scale
factor of 1/3 centered at the origin.
The coordinates of the image of the vertices of the polygon are A''(x, y) = (1, - 2), B''(x, y) = (2, - 2), C''(x, y) = (0, - 1), D''(x, y) = (- 1, - 2) and E''(x, y) = (- 2, - 1).
What are the images of the vertices of a polygon by using rigid transformations?
Rigid transformations are transformations applied on geometric loci such that Euclidean distances in such constructions are conserved. Translations and dilations are common examples of rigid transformations.
If we know that A(x, y) = (- 6, 0), B(x, y) = (- 3, 0), C(x, y) = (0, - 3), D(x, y) = (- 3, - 6) and E(x, y) = (- 6, - 3), then the coordinates of the image are determined below:
Translation
A'(x, y) = (- 6, 0) + (9, - 6)
A'(x, y) = (3, - 6)
B'(x, y) = (- 3, 0) + (9, - 6)
B'(x, y) = (6, - 6)
C'(x, y) = (0, - 3) + (9, - 6)
C'(x, y) = (9, - 9)
D'(x, y) = (- 3, - 6) + (9, - 6)
D'(x, y) = (6, - 12)
Dilation
A''(x, y) = (1 / 3) · (3, - 6)
A''(x, y) = (1, - 2)
B''(x, y) = (1 / 3) · (6, - 6)
B''(x, y) = (2, - 2)
C''(x, y) = (1 / 3) · (0, - 3)
C''(x, y) = (0, - 1)
D''(x, y) = (1 / 3) · (- 3, - 6)
D''(x, y) = (- 1, - 2)

a radioactive substance decays exponentially. a scientist begins with 180 milligrams of a radioactive substance. after 33 hours, 90 mg of the substance remains. how many milligrams will remain after 43 hours?
The radioactive substance remaining after 43 hours is: 62.7273 mg by unitary method.
What is unitary method?A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.
Now,
Given that 180 mg is present at t = 0 hours.
After t = 33 hours, substance left = 90mg
By unitary method, after = 1 hour, substance left = [tex]180-\frac{90}{33}=180 -\frac{30}{11}[/tex]mg
The substance left after t = 43 hours = [tex]180 - \frac{30\times43}{11}= 180 - \frac{1290}{11}=180 - 117=62.7273mg[/tex]

Algebra is the branch of mathematics that represents problems and situations in the form of mathematical expressions. It contains variables such as x, y, z, and operations such as addition, subtraction, multiplication, and division to form meaningful mathematical expressions.Algebra is used mostly in all areas of mathematics like trigonometry, calculus, and coordinate geometry. A simple example of an algebraic expression is 9x + 4 = 8. Algebra deals with symbols, and these symbols are related to each other by operators. It's not just a mathematical concept, it's a skill that we all use subconsciously in our daily lives.
Let x be the number of matinee tickets.
In that case, the number of student tickets is 2x.
The number of regular tickets is (8500-x-2x) = (8500-3x).
Total money
5x + 6*(2x) + 8.50*(8500-3x) = 64600
Simplifying and solving for x
5x + 12x - 8.50*3*x + 8.50*8500 = 64600
5x + 12x - 8.50*3*x = 64600 - 8.50*8500
Solving x , we get
x = 900
Number of matinee tickets = 900
Number of student tickets = 1800
Number of regular tickets = 8500 - (900+1800) = 5800

4. Joyce works at Coronado's Furniture. She is paid on commission. She receives
10% of her first $900 in sales and 15% of the balance of her sales. Last week she
earned $750. What was the total value of the furniture she sold?
The total value of the furniture she sold is $4400.
How to compute the value?Let the remaining sales be represented by x.
She receives 10% of her first $900 in sales and 15% of the balance of her sale.
This will be:
(10% × $900) + (15% × x) = 750
90 + 0.15x = 750
Collect like terms
0.15x = 750 - 90
0.15x = 660
Divide
x = 660/0.15
x = 4400
