What is the cost of a pair of jeans that sells for $49 if the sales tax rate is 6%
a pair of jenas that sell for $49
rate of tax is 6%
cost of that jeans is ?
Let the cost of jeans = x
through question
or, $49 = X + X×6%
or,$49 = X + X×6/100
or, $49 = 106X/100
or, $4900 = 106X
or, X = $4900/106
: X = $46.226
thus ; the cost of jeans is $46.226
Answer:
51.94
Step-by-step explanation:
6% of 49 is 2.94. 49 + 2.94 = 51.94

Prove each of these identities.
(a) tan x + cot x = secx cosecx
(b) cosec x - sin x = cos x cot x
Answer:
Identity (a) can be re-written as
[tex]sec x\ cosec x - cot x = tan x[/tex]
which we already proven in another question, while for idenity (b)
[tex](A)\frac 1 {sin x} -sin x = cos x \frac{cos x}{sin x}\\\\(B)\frac {1-sin^2x}{sin x} = \frac {cos^2x} {sin x} \\\\(C) \frac {cos^2x}{sin x} =\frac {cos^2x} {sin x}[/tex]
step A is simply expressing each function in terms of sine and cosine.
step B is adding the terms on the LHS while multiplying the one on RHS.
step C is replacing the term on the numerator with the equivalent from the pithagorean identity [tex]cos^2x + sin^2x = 1[/tex]

One rectangle is "framed" within another. Find the area of the shaded region if the
"frame" is 2 units wide.
10
7
The area of the shaded rectangle is 18 square units.
How to get the area of the shaded region?
The shaded region is the framed rectangle, and the white part is the frame.
We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:
width = 7 unitslength = 10 unitsNow, if we remove the frame, we will remove 2*2 units = 4 units for each measure (because for each measure we have the frame in both sides).
So the measures for the shaded rectangle are:
width = 7 units - 4 units = 3 unitslength = 10 units - 4 units = 6 units.And the area of a rectangle is given by the product between the width and length, then we have:
A = (3 units)*(6 units) = 18 square units.

Answer:
In total, Esme will need to purchase at minimum TWELVE (12) pieces of fence in order to encompass her entire rectangular garden.
Step-by-step explanation:
Let us start off by isolating each of the two different length sides, and figure out which fence pieces can be used to it off.
For the three meter (3 m) side, we could utilize the following THREE (3) pieces...
ONE (1) piece of 1.8 m length fenceTWO (2) pieces of 0.6 m length fenceAdding up those pieces provides us with our desired garden side length...
(1 × 1.8 m) + (2 × 0.6 m) = 3.0 m!
For the six meter (6 m) side, we could utilize the following THREE (3) pieces...
ONE (1) piece of 1.8 m length fenceTWO (2) pieces of 2.1 m length fenceAdding up those pieces provides us with our desired garden side length...
(1 × 1.8 m) + (2 × 2.1 m) = 6.0 m!
We ought to not forget about the opposite sides of the aforementioned, to make up the four sides of the rectangle! In short, we double the number of pieces that we currently have...
In the end, the smallest number of pieces of fence that Esme will need to buy is TWELVE (12), consisting of the following pieces:
TWO (2) pieces of 0.6 m length fence TWO (2) pieces of 1.8 m length fenceTWO (2) pieces of 2.1 m length fenceI hope this helps! :)
6. 2A and ZB are complementary angles. The measure of ZB is (4x), and the
measure of ZA is 50°. What is the value of x?
Answer:
x = 10°
Step-by-step explanation:
ZA + ZB = 90°
50° + 4x = 90°
4x = 90° - 50°
4x = 40°
x = 10°

a shop sells large and small oranges . a girl buys L large oranges ams S samll oranges. she buys al least three but fewer than nine large oranges. she also buys fewer than six small oranges. the maximum number of oranges needs to buy is 10
Answer:
Number of large oranges: x
Number of small oranges: y
y < 6
x + y <= 10
Hope it helps!!!!!!brainliest pls!!!!!!!!The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).
Let's represent the number of large oranges as "L" and the number of small oranges as "S."
From the given information, we have the following conditions:
At least three but fewer than nine large oranges: 3 ≤ L < 9
Fewer than six small oranges: S < 6
The maximum number of oranges she needs to buy is 10: L + S ≤ 10
Now, let's consider the possible combinations of L and S that satisfy these conditions:
L = 3, S = 0 (Total oranges = 3)
L = 4, S = 0 (Total oranges = 4)
L = 5, S = 0 (Total oranges = 5)
L = 6, S = 0 (Total oranges = 6)
L = 7, S = 0 (Total oranges = 7)
L = 8, S = 0 (Total oranges = 8)
L = 3, S = 1 (Total oranges = 4)
L = 4, S = 1 (Total oranges = 5)
L = 5, S = 1 (Total oranges = 6)
L = 3, S = 2 (Total oranges = 5)
L = 4, S = 2 (Total oranges = 6)
L = 3, S = 3 (Total oranges = 6)
As you can see, these are all the possible combinations of L and S that satisfy the given conditions. The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).

Which values complete the function? f(x) = (x – )(x ).
The values needed for completing the function to match with its graph is [tex]f(x) = -(x+4)(x-3)[/tex]
How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.Analysis of this leads to the relations which were used to make it.For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.The graph of the considered problem which is missing is attached below.
Let the completed function is
[tex]f(x) = a(x-b)(x-c)\\[/tex]
Then the roots of the function would be the values of x at which the function becomes 0, and they are [tex]x = b[/tex] and [tex]x = c[/tex]
Since the graph crosses the x axis at -4 and 3, therefore, as the points on x axis are the roots of the functions of variable x, therefore, we get:
b and c to be -4 and 3, therefore, the function is
[tex]f(x) = a(x-(-4))(x-3) = a(x+4)(x-3)[/tex]
Since the function crosses the y axis at y = 12, and since on y axis, the value of x is 0, therefore, putting x = 0, and equating the output to 12, we get:
[tex]f(x) = a(x+4)(x-3)\\12 = a \times 4 \times -3\\12 = a \times -12\\\\\text{Dividing both the sides by -12}\\\\\dfrac{12}{-12} = a\\\\a = -1[/tex]
Therefore, the completed function would look like:
[tex]f(x) = -(x+4)(x-3)[/tex]
Thus, the values needed for completing the function to match with its graph is [tex]f(x) = -(x+4)(x-3)[/tex]

How many different 4-digit PIN codes are there that only include the digits 4, 5, 7, 8 and 6
if each of those digits is only allowed to be used once?
Answer:
Available Digits = 4 (1, 2, 3 , 4)
Step-by-step explanation:
Now, if the digits can be used only once, it is a case of permuting 4 things out of 4 things i.e. 4P4=24ways
Alternatively, the units place can be filled in 4 ways, tens place can be filled in 3 ways, hundreds place can be filled in 2 ways and thousands place in 1 way.

Marcus is buying a plane ticket. If he purchases his ticket on the day of his departure, it will cost $239. The ticket costs less if he buys it earlier. If he purchases it 20 days before his departure, it will cost $189. Model this situation by using a linear function. Then determine the cost of the ticket if Marcus buys it 3 days before his departure.
The modelled situation in a linear format is y = [tex]-\frac{5}{2}x+239[/tex]
The cost of the ticket if Marcus buys it 3 days before his departure is $231.5
Linear equationy = mx + b
where
m = slope
b = y-intercept
b = 239
Therefore, let's model the situation to a linear equation.
y = mx + 239
using (20, 189)
189 = 20m + 239
189 - 239 = 20m
-50 = 20m
m = [tex]-\frac{5}{2}[/tex]
Therefore,
y = [tex]-\frac{5}{2}x +239[/tex]
where
x = The day before departure
y = cost of ticket
To determine the cost of the ticket if Marcus buys it 3 days before his departure.
y = [tex]-\frac{5}{2}(3)+239[/tex]
y = -7.5 + 239
y = $231.5

which number is divisible by 5? 83 45 94 99
Answer:
45
Step-by-step explanation:
9x5
=45
Answer:
45
Step-by-step explanation:
To be divisible by five, the number must end with a zero or a five, and forty-five is the only number that meets these conditions. Technically, all the numbers are divisible by five, but 83, 94, and 99 divided by five would equal a whole number with a decimal, meaning the only option that equals a whole number is forty-five (45).
