Answer: B: 11 and 12
Step-by-step explanation:
- An integer is simply a whole number
- So consecutive integers are simply whole numbers that follow each other (ex: 1, 2, 3)
- The square root of 125 (in decimals) is 11.1803398875, meaning it is higher than 11 but less than 12
- So 11.1803398875 falls between 11 and 12, making the answer B

Suppose A and B are 2x2 matrices and that AB = BA =
which of the following statements is correct?
The correct statement about the matrix is B. B^-1.
How to illustrate the matrix?From the information, it can be seen that the matrix is 2 by 2. Based on the information about the matrix, 1/3AB = 1/3BA.
From this, it can be depicted that the inverse of B illustrates that:
A(1/3B) = (1/3B)
This illustrates that the correct is B.

Mason is a songwriter who collects royalties on his songs whenever they are played in
a commercial or a movie. Mason will earn $30 every time one of his songs is played in
a commercial and he will earn $80 every time one of his songs is played in a movie.
Mason earned a total of $470 in royalties on 9 commercials and movies. Write a
system of equations that could be used to determine the number of commercials and
the number of movies on which Mason's songs were played. Define the variables that
you use to write the system.
Answer:479
Step-by-step explanation:470+9=479
We can write the system of equation that determines the number of commercials and the number of movies on which Mason's songs were played as → 30x + 80y = 470 and x + y = 9. The variables used in the system of equations are -
x - Number of times his song played in a commercial
y - Number of times his song played in a movie.
What is equation modelling?
Equation modelling is a method of writing a mathematical relation from a mathematical statement for mathematical analyses of the problem given.
Given is Mason who collects royalties on his songs whenever they are played in commercials or movies.
Assume that his song played in 'x' commercials and 'y' movies.
Cost per song when played in commercial = $30
Then for 'x' commercials, total cost will be = $30x
Cost per song when played in movie = $80
Then for 'y' movies, total cost will be = $80y
Total money earned through both = $470
We can write the system of equation that determines the number of commercials and the number of movies on which Mason's songs were played as -
30x + 80y = 470
The total number of commercials and movies combined -
x + y = 9
The variables used in the system of equations are -
x - Number of times his song played in a commercial
y - Number of times his song played in a movie.
Therefore, We can write the system of equation that determines the number of commercials and the number of movies on which Mason's songs were played as → 30x + 80y = 470 and x + y = 9. The variables used in the system of equations are -
x - Number of times his song played in a commercial
y - Number of times his song played in a movie.

Maria bought a stock for x dollars, and she sold it at a profit of 20 %. Write a
mathematical expression for the selling price.
Answer: 1.2x
Step-by-step explanation:
Profit = Selling price - Cost
She bought the stock at a cost of x dollars
Her profit was 20% of that, which is 0.2x dollars
Selling price = Profit + Cost = x + 0.2x = 1.2x
Tim Hortons is hiring and offers $200 every week plus $5 per hour. McDonalds offers $300 every week plus $2 per hour. State the conditions under which Tim Hortons is the better employer.
Answer: After working for 33 [tex]\frac{1}{3}[/tex] hours a week
Step-by-step explanation:
Let us write equations to represent these two places. Let x be hours worked and y be money earned.
Tim Hortons:
$200 + $5x = y
McDonalds:
$300 + $2x = y
Now, to find the conditions of which Tim Hortons is the better employer (on the basis of money earned) we must find the interval that Tim Hortons pays more. This can be found by setting up another equation, or by graphing. I have shown both. See attached for the graph.
$200 + $5x > $300 + $2x
$5x > $100 + $2x
$3x > $100
x > [tex]\frac{100}{3}[/tex]
x > 33.3334

Hence, since the numerator and denominator polynomials are of the same order, it follows that the horizontal asymptote is the quotient; 3/1 = 3.
Additionally, the vertical asymptote of the function is the value of x which renders the denominator equal to 0 and consequently, the function undefined.
Hence, x -2 = 0 and x= 2.

You withdraw $140 from your savings account. then you withdraw $49 more. using an integer, which number represents your balance?
The integer represent the balance in your account is Z = + Y. The representation of integer is positive because withdrawal is always less then or equal to the amount present in the bank account.
Total rupees withdraw from saving account is $149
Let total amount in account before withdrawing is X= $500
Amount left after withdraw the money is calculated by a
AMOUNT LEFT = TOTAL AMOUNT - WITHDRAW AMOUNT
So, put the values then
Y= X($500) - $149
Y= $500 - $149
Y= $351
If we represent the balance of saving account in the integer form then it become the Z = + Y. The representation of integer is positive because withdrawal is always less then or equal to the amount present in the bank account.

Solve each triangle – find any missing side and angle measures. Round answers to the nearest tenth.
Answer:
A = 55 degrees
B = 35 degrees
C = 90 degrees
side BA = 4.8 units
side AC = 2.7 units
side BC = 3.9 units
Step-by-step explanation:
Hello!
The things we know:
A = 55 degrees
C = 90 degrees
side BA = 4.8 units
AC = adjacent side
BC = opposite side
AB = hypothenuse
B = 180 - 55 - 90 degrees
B = 35 degrees
Let's find side AC
we can use the cos of theta.
cos(55) = AC/4.8
multiply 4.8 on both sides.
4.8cos(55) = AC
AC = 2.7 units
And now we just have to find BC
to calculate BC we can either use tangent or sin.
I will just use sin
sin(55) = BC/4.8
multiply 4.8 on both sides.
4.8sin(55) = BC
BC = 3.9
And now we know everything about the triangle
Hope I Helped!

Alex and Bobby are in the woods and are standing 240
yards apart.. Both boys spot a plane with angles of
elevation of 40 degrees and 45 degrees respectively. How
far from the plane is Bobby? Round to the nearest tenth of
a yard. Enter a number answer only.
The distance from Bobby to the plane is 154.7 yards.
How to find the distance of the plane to Bobby using angle of elevation?Sine law can be used to find the distance of the plane to Bobby.
Therefore,
x / sin 40 = 240 / sin 95
cross multiply
Hence,
x sin 95 = 240 sin 40
divide both sides by sin 95
x = 240 sin 40 / sin 95
x = 240 × 0.64278760968 / 0.99619469809
x = 154.08 / 0.9961
x = 154.683264732
x = 154.7 yards

For what values of k will the function f(x) = 9x² + 4x + k have 1 real roots.
Hello,
Answer:
for k = 4/9
Step-by-step explanation:
a = 9 ; b = 4 ; c = k
we search Δ = 0 (because 1 real root)
Δ = b² - 4ac = 4² - 4 × 9 × k = 16 - 36k
Δ = 0 ⇔ 16 - 36k = 0 ⇔ 36k = 16 ⇔ k = 16/36 = (4 × 4)/(4 × 9) = 4/9
⇒ k = 4/9
Answer:
[tex]\{\frac{4}{9} \}[/tex]
Step-by-step explanation:
First off, we are given a parabola by definition:
[tex]f(x) = 9x^2 + 4x + k \\ a = 9, b = 4, c = k;[/tex]
Since [tex]a > 0[/tex], our parabola has an upward opening.
Should we think about it graphically, it will be no wonder that we should pay our attention to the points of the parabola intersecting the abscissa axis. In other words, we need our vertex to intersect the x axis only once per se.
The vertex:
[tex]V_{x} = \frac{-b}{2a} = \frac{-4}{2 * 9} = - \frac{2}{9} \\ V_{y} = 9V_{x}^2 + 4V_{x} + k = 9(- \frac{2}{9})^2 + 4(- \frac{2}{9}) + k = 9 * \frac{4}{9^2} - \frac{8}{9} + k = \frac{4}{9} - \frac{8}{9} + k = - \frac{4}{9} + k[/tex]
As a result, our [tex]V_{y}[/tex] is parametric. [tex]k = \frac{4}{9}[/tex] suits us because [tex]V_{y} = - \frac{4}{9} + \frac{4}{9} = 0[/tex]. If [tex]k > \frac{4}{9}[/tex], we do not have any roots at all. We have two roots if [tex]k < \frac{4}{9}[/tex].
