7:40pm------What is 89 minutes more? (What time will it be?)
Answers
The current time is 08 : 09 pm
How to determine the current time?The given parameters are
Time = 7 : 40 pm
Minutes added = 89 minutes
The current time is calculated as
Current time = Time + Minutes added
So, we have
Current time = 7 : 40 pm + 89 minutes
Evaluate the sum
Current time = 7 : 129 pm
Rewrite properly as
Current time = 08 : 09 pm
Hence, the current time is 08 : 09 pm

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
Answers
(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 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.
Answers
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)
E''(x, y) = (1 / 3) · (- 6, - 3)
E''(x, y) = (- 2, - 1)

Values at one, two and three standard deviations are 77.9, 82.8 and 87.7 respectively. Values at -1, -2 and -3 standard deviations are 68.1, 63.2 and 58.3 respectively.
The average grade given = 73
So, the mean, μ = 73
The standard deviation, σ = 4.9
We need to find the 1,2 and 3 standard deviations and -1, -2 and -3 deviations from the mean.
We use the formula z = μ + nσ to find the values at nth deviations.
When n = 1
z = 73 + 1 x 4.9 = 77.9
When n = 2
z = 73 + 2 x 4.9 = 82.8
When n = 3
z = 73 + 3 x 4.9 = 87.7
When n = -1
z = 73 -1 x 4.9 = 68.1
When n = -2
z = 73 - 2 x 4.9 = 63.2
When n = -3
z = 73 - 3 x 4.9 = 58.3
Hence, these are the required values.

To find it, we just need to take the quotient between the number of students that walk to the school and the total number of students.
The number of students that walk to the school is:
42 + 36 = 78
The total number of students is:
85 + 77 + 30 + 47 + 42 + 36 + 44 + 39 = 400
Then the probability is:
P = 78/400 = 0.195

if w≠0, what is the additive inverse of the expression -3/w
Answers
The additive inverse of the expression -3/w is 3/w.
A number is known as the additive inverse of another, if the sum of the two numbers comes out to be zero. For example- given a number 3, its additive inverse will be -3, as 3 + (-3) = 0. The additive inverse of 0 is 0 itself.
Here, we are given an expression -3/w, such that w ≠ 0
Let us assume that the additive inverse of -3/w is x
Then, the sum of -3/w and x must be equal to zero
⇒ -3/w + x = 0
adding 3/w to both sides
⇒ x = 3/w
Thus, the additive inverse of -3/w is 3/w.

What fraction of members in the club
prefer hot chocolate?
Give your answer as a fraction in its
simplest form.
Answers
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.

b. If Mai-Lin's target heart rate is 153, then how old is she? What property justifies your calculation?
Answers
When Mai-Lin's target heart rate is 153, then her age is 16 years.
How to illustrate the function?From the information, the The American Heart Association suggests a target heart rate of T=0.75(220-a),
where T = person's target heart rate
a = his or her age.
Therefore, when the heart rate is 153, the age will be:
T = 0.75(220 - a)
153 = 165 - 0.75a
0.75a = 165 - 153
0.75a = 12
Divide
a = 12/0.75
a = 16
The person's age is 16 years.
