Answer:
Rushbu exchanges 300 USD at the buying rate of NRs 119.25, so she will receive:
300 x 119.25 = NRs 35775
After allowing a 10% discount, Rushbu will need to pay:
35000 - (10/100 x 35000) = NRs 31500
Including 13% VAT, Rushbu will need to pay:
31500 + (13/100 x 31500) = NRs 35655
Since Rushbu received NRs 35,775 after exchanging her 300 USD, she will have enough Nepali currency to buy the television, even after accounting for the discount and VAT.
Therefore, Rushbu will have enough money to buy the television, and she will have NRs 120 less than she received from exchanging her 300 USD, but that does not affect her buying capacity in this case.
Shebane rolls a standard six sides number cube. Find p
Answer:
2/3
Step-by-step explanation:
A six sided number cube :
Sample space = 1,2,3,4,5,6
Non composite numbers on a six sided number cube = 1,2,3,5
Probability of an event = required outcome / Total possible outcomes
Required outcome = number of non composite number = 4
Total possible outcomes = sample space = 6
P(not composite)= 4/6 = 2/3

What values of y and z make
The value of y and z are 11 and 11.
How to determine the valuesWe can see from the diagram that the two triangles are of equal lengths.
To determine the value of the variables, we have to note that;
In triangle QRS, the adjacent sides is y + 20
In triangle VX, the adjacent side is y = 31
Now, equate the values
y + 20 = 31
collect like terms
y = 31 -20
y = 11
Also, the hypotenuse sides are equivalent, then
y + 3z + 28 = 6y + z - 5
collect the like terms
y - 6y + 3z - z = -5 - 28
add or subtract the values
-5y + 2z = -33
Substitute the values
2z = -33 + 55
2z = 22
z = 11

Find the critical numbers and absolute extrema for….
Final Answer: The critical number is x = DNE. The absolute maximum is x = 0.2, and y = -125.The absolute minimum does not exist on the interval.
To find the critical numbers?we need to find the values of x where the derivative of y equals zero or does not exist. So, we first find the derivative of y: y' = 10x^{(-3)}
The derivative is defined for all x in the interval [0.2, 2], so there are no points where the derivative does not exist.
To find where y' = 0, we set the derivative equal to zero and solve for x: [tex]10x^{(-3)} = 0[/tex] x = DNE There are no critical numbers since the derivative does not equal zero at any point in the interval.
Next, we check the endpoints of the interval: [tex]y(0.2) = -5/ (0.2^2) =[/tex] [tex]-125y(2) = -5/(2^2) = -1.25[/tex] Since y is a decreasing function on the interval,
the absolute maximum occurs at the left endpoint x=0.2: Absolute maximum: [tex]y(-0.2) = -125[/tex]
Since y is an unbounded function as x approaches zero, there is no absolute minimum on the interval [0.2, 2].
Final Answer: The critical number is x = DNE.The absolute maximum is x = 0.2, and y = -125.The absolute minimum does not exist on the interval.

You mix gas and oil to obtain 2 and 1/2 gallons of mixture for an engine. The mixture is 40 parts gasoline and 1 part oil. How much gasoline must be added bring the mixture to 50 parts gasoline and 1 part oil?
We need to add a volume of 39.69 fluid ounces of gasoline to the mixture to bring it to 50 parts gasoline and 1 part oil.
What is mensuration?Mensuration is the branch of mathematics concerned with the measurement of geometric figures and parameters such as length, volume, shape, surface area, and lateral area.
According to information in the question:
The mixture is 40 parts gasoline and 1 part oil, there are 40 + 1 = 41 parts in total.
Let, the amount of oil in the mixture "x".
We know that there are 2 and 1/2 gallons of the mixture, which is the same as 2.5 * 128 = 320 fluid ounces.
So, the equation which can be formed is
x/41 * 320 = the amount of oil in the mixture (in fluid ounces)
Solving for "x":
x/41 * 320 = x/41 * 50 + 320 - (x/41 * 50)
Multiplying both sides by 41:
x * 320 = 50x + 41(320 - 50x)
Simplifying:
320x = 41(320)
x = 41 * 10 = 410 (fluid ounces of oil in the mixture)
Thus, amount of gasoline in the mixture is
40 parts gasoline / 41 parts total * 320 fluid ounces = 311.22 fluid ounces of gasoline.
Let the gasoline we need be "y", so a equation can be formed as follows
(311.22 + y)/(41 + y) * 320 = 410
Solving for y:
(311.22 + y)/(41 + y) = 410/320
Multiplying both sides by (41 + y) * 320:
311.22 + y = 410/320 * (41 + y) * 320
Simplifying:
311.22 + y = 205.625 * (41 + y)
311.22 + y = 8434.375 + 205.625y
Solving for y:
204.625y = 8123.155
y = 39.69 (fluid ounces of gasoline to add)
Therefore, we need to add 39.69 fluid ounces volume of gasoline to the mixture to bring it to 50 parts gasoline and 1 part oil.

f(x) = 2x - 1 g(x) = 7x + 8 find (gof) (x)
Answer:
(gof)(x) = 14x + 1
Step-by-step explanation:
We can think of (gof)(x) as g(f(x)). Writing it in this form shows that we must start with the inner function and work our way to the outer function.
Essentially, the input of the inner function yields an output and the output becomes the input of the outer function.
f(x) means that the input is x and since we're given no value for x (e.g. x = so and so), the output is the original function or 2x - 1
Now, this output becomes the input for g(x):
g(2x-1) = 7(2x - 1) + 8
14x -7 + 8
(gof)(x) = 14x + 1

These are parallelograms, meaning the opposite sides are parallel. Since they are parallel, that the line EA becomes a transversal and a bisector for the angle CEK. That means the angle 8 and 3 are equivalent and 7 and 4 are equivalent. This is due to Same Side Interior Angles. These are two halves of the big angle. If the halves are equal, so are the angles. Therefore, CEK = CAK.

If you know the coordinates for points between A and B, that you can use this method to determine the dimensions of the spot that is located (0, 1/3) between A and B.
What do coordinates number mean?A set of integers called coordinates are used to locate a spot or a shape in a two-dimensional plane. The x-coordinate as well as the y-coordinate are two integers that describe a point's location on a [tex]2D[/tex] plane.
To find the coordinates of the point that is [tex]1/3[/tex] of the way from point A to point B. we can use the midpoint formula, which states that the coordinates of the midpoint of the line segment joining two points [tex](x1, y1)[/tex]and [tex](x2, y2)[/tex] are:
[tex]((x1 + x2)/2, (y1 + y2)/2)[/tex]

How do I get domain for (x-7)(x-1) over (x+3)(x-1)
Answer:
To find the domain of the function f(x) = (x-7)(x-1)/(x+3)(x-1), we need to consider the values of x that make the denominator zero since division by zero is undefined.
In this case, the denominator (x+3)(x-1) is zero when x = -3 and x = 1. Therefore, we need to exclude these values from the domain.
So, the domain of f(x) is all real numbers except x = -3 and x = 1.
In interval notation, we can write the domain as (-∞, -3) U (-3, 1) U (1, ∞).

The linear function can be written as:
f(x) = -x/3 + 17/3
How to find the linear function?A general linear function can be written as:
f(x) = ax + b
Where a is the slope, and b is the y-intercept.
If we know two points on the line (x₁, y₁) and (x₂, y₂), then the slope of the linear function is:
a= (y₂ - y₁)/(x₂ - x₁)
Here we know the pairs:
f(-4) = 7
f(5) = 4
So we have the points (-4, 7) and (5, 4), then the slope is:
a = (4 - 7)/(5 + 4) = -3/9 = -1/3
Then we can write:
f(x) = -x/3 + b
now we can use one of the given points, like f(5) = 4, replacing that there we will get:
4 = -5/3 + b
4 + 5/3 = b
12/3 + 5/3 = b
17/3 = b
So the function is:
f(x) = -x/3 + 17/3

the unit rate for this relationship is 1 gallon per 18.25 minutes
The amount of liquid that can be processed in 2 hours at a unit rate of 1 gallon per 18.25 minutes is calculated to be approximately 6.58 gallons.
What is unit rate?
A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.
Assuming the unit rate of 1 gallon per 18.25 minutes, we can convert 2 hours to minutes by multiplying it by 60, which gives us 120 minutes.
So, in 120 minutes, the amount of liquid that can be processed at a unit rate of 1 gallon per 18.25 minutes would be:
(120 minutes) / (18.25 minutes/gallon) = 6.58 gallons
Therefore, the amount of liquid that can be processed in 2 hours at a unit rate of 1 gallon per 18.25 minutes is found out to be approximately 6.58 gallons.

In circle C with the measure of minor arc BD=42°, find mBED.
Answer: mBED = 2(42°) = 84°
Step-by-step explanation:
We are asked to find the measure of the central angle ∠BED in the circle given that the measure of the minor arc BD is 42°.
We can use the formula that states that the measure of a central angle is equal to twice the measure of its intercepted arc. That is,
m∠BED = 2*mBD
We can substitute the value of mBD, which is 42°, into our equation.
m∠BED = 2*42°
m∠BED = 84°
Therefore, the measure of the central angle ∠BED is 84°.

B.Slope is zero and the y-intercept is (0,-5)
C. Slope is zero and the y-intercept is (0,0)
D. Slope is -5 and the y-intercept is (0,-5)
Slope is zero and the y-intercept is (0,-5)
What is slope ?
In mathematics, slope is a measure of the steepness of a line. It is defined as the ratio of the vertical change (rise) between two points on the line to the horizontal change (run) between the same two points.
In other words, the slope of a line is the change in the y-coordinate divided by the change in the x-coordinate between any two points on the line. It can also be thought of as the rate at which the line rises or falls as it moves horizontally.
The formula for calculating slope is:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
According to the question:
The equation Y = -5 is already in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
Comparing the equation Y = -5 to y = mx + b, we can see that:
The slope, m, is 0, since there is no x-term in the equation.
The y-intercept, b, is -5, since that is the constant value in the equation.
Therefore, the correct answer is:
B. Slope is zero and the y-intercept is (0,-5)
