The angle 180  is not an acute angle.

We know that an angle is the figure, in which two rays meet at a common point (vertex).

The types of angles (based on their magnitude) are:

Acute Angle (angle measuring greater than 0° and less than 90°)

Obtuse Angle, (an angle which is less that 180° and greater than 90°)

and Right Angle (an angle that measures 90°)

There are some types of angle based on their rotation:    

Straight Angle, (an angle measuring 180 degrees)

Reflex Angle, (an angle which is greater than 180 degrees but less than 360 degrees )

and Full Rotation (an angle measuring 360 degrees)

From the definition of acute angle,

acute angle measures greater than 0° and less than 90°

So, 180 degrees can not be an acute angle.

Step-by-step explanation:

The total discount tickets sold are 8460 tickets.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.


The discount equals the difference between the price paid for and it's par value. Discount is a kind of reduction or deduction in the cost price of a product. It is mostly used in consumer transactions, where people are provided with discounts on various products. The discount rate is given in percentage.


We have that,
94% = 94/100
       = 0.94

By multiplying the tickets sold by the factor of 0.94, we get

0.94 × 9000
8460 tickets

The inequality that can be used to determine x, the maximum number of outfits Luis can purchase while staying within his budget is x ≤ 4

How is inequity resolved?

Luis has $420 to spend at a bicycle shop on new accessories and clothing.

He spends $209.67 on a brand-new bicycle.

He spends $6.04 apiece on two bicycle reflectors and $25.77 on a pair of cycling gloves.

He intends to use all or part of the remaining funds to purchase new riding clothing at $37.16 apiece.

Therefore,

x is the maximum amount of clothes Luis can buy on a tight budget.

In order to illustrate the scenario, the inequality that may be employed is as follows:

209.67 + 6.04(2) + 25.77 + 37.16x ≤ 420

235.44 + 12.08 + 37.16x ≤ 420

247.52 +  37.16x ≤ 420

37.16x ≤ 420 - 247.52

37.16x ≤ 172.48

divide both sides by 37.16

x ≤ 4.64155005382

x ≤ 4

Therefore, the inequality that can be used to determine x, the maximum number of outfits Luis can purchase while staying within his budget is x ≤ 4

The formula is a fact or a rule written with mathematical symbols. It usually connects two or more quantities with an equal sign.

In arithmetic, a chain is an enumerated series of gadgets in which repetitions are allowed and order matters. Like a hard and fast, it consists of contributors (additionally referred to as elements, or terms). The quantity of elements (possibly endless) is called the duration of the series.

Unlike a fixed, the same factors can appear a couple of times at distinct positions in a chain, and unlike a fixed, the order does be counted. formally, a chain can be described as a function from herbal numbers (the positions of elements inside the collection) to the factors at each position.

The solution to the system of inequalities given by x + y > −2 and −x + y < 1 is the ordered pair that lies under the conditions x > -3/2 and y > -1/2. One of which is (1, 0).

An inequality is a statement about the relative size or order of two values. It's a statement that one value is greater than, less than, greater than or equal to, less than or equal to, or not equal to another value. It's represented using mathematical symbols such as <, >, ≤, ≥, ≠.

To find the solution to a system of inequalities, rewrite any of the two inequalities as y in terms of x.

x + y > -2 can be rewritten as y > -x - 2

Substitute the value of y into the other inequality.

-x + y < 1 will become -x + (-x - 2) < 1

Solve for the value of x.

-x + (-x - 2) < 1

-2x -2 < 1

-2x < 1 + 2

-2x < 3

2x > -3

x > -3/2

Plug in the value of x into the equation of y and solve for y.

y > -x - 2

y > -(-3/2) - 2

y > -1/2

So, the solution of the system of inequalities will be the region where both of these conditions, x > -3/2 and y > -1/2, are true, which is the area where the graph of y > -x - 2 and y < x + 1 overlap.

One ordered pair (1 , 0) is a solution to the system of inequalities x + y > -2 and -x + y < 1.

We can check it by plugging in the ordered pair into the inequalities.

x + y > -2 becomes 1 + 0 > -2 which is true

-x + y < 1 becomes -1 + 0 < 1 which is true

So (1,0) satisfies both inequalities.

Answer:

y = 7x + 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

here m = 7 , then

y = 7x + b ← is the partial equation

to find b substitute (1, 8 ) into the partial equation

8 = 7(1) + b = 7 + b ( subtract 7 from both sides )

1 = b

y = 7x + 1 ← equation of line

No, "FG)(x)" and "g/f)(x)" are not inverse of each other."FG)(x)" refers to the composition of two functions, "F" and "G", where the output of "G" is used as the input for "F".

The notation for this is represented as "F(G(x))", where "x" is the input for both functions.

The function "F" is applied to the output of the function "G", meaning that the output of the function "G" is used as the input for the function "F".

On the other hand, "g/f)(x)" is not a standard notation in mathematics. It could be interpreted as applying the function "g" to the input "x", and then applying the function "f" to the result of "g". But it could also be interpreted as applying f to the input x and then applying g to the result of f.

Inverse functions are related to the idea of reversing the effect of a function. For example, if "f" is a function that maps a set of inputs to a set of outputs, then the inverse function "f^-1" maps the set of outputs back to the original set of inputs. The notation for an inverse function is typically represented as "f^-1(x)" or "f^(-1)(x)". It's important to note that not all functions have inverses, and the inverse of a function is also a function.

When you divide a fraction by a negative number, it doesn't matter what happens to the denominator because the entire result, or quotient, is the reverse of whatever the original fraction was.

In mathematics, a denominator is the lowest number in a fraction that indicates how many equal parts are divided into a whole.

It is a fraction's divisor. In this case, the denominator is 4, thus there are four components overall.

The top number in a fraction is referred to as the numerator, while the bottom number is referred to as the denominator.

4/5, for instance, is a fraction.

What happens to the denominator of a fraction when you divide it by a negative number is unimportant because the entire result, or quotient, is the opposite of whatever the original fraction was.

Write down the set of numbers for which you want to find the GCF.

Starting from 1, check if each number in the set is divisible by it. If all the numbers are divisible by it, mark it as a common factor.

Repeat step 2, incrementing the number by 1, until you reach the smallest number in the set.

The largest common factor that you marked in step 2 is the GCF.

This method is based on the idea of checking each number starting from 1 till the smallest number in the set and checking if it is divisible by all numbers in the set. It's a simple method that can be applied to find GCF of any set of numbers.

It's worth noting that this method may not be the most efficient way to find GCF of set of numbers, as it involves checking each number starting from 1 till the smallest number in the set. In cases where the numbers are large, more efficient methods like prime factorization and Euclidean algorithm are preferred.

Answer:

Approximately 2.3 hours after 12 noon

Step-by-step explanation:

We are given
Stock A price at 9AM = $13.45
It increases by $0.08 per hour

Stock B at noon = $14.20
It decreases by $0.14 each hour

We have to find when the two prices will be the same.

Since the base time references are different - 9am for A and noon for B, we have to establish the same time reference

Let's do this by finding the price of stock A at noon, then we have the same time base reference of noon

9am - noon = 3 hours

In 3 hours stock A would have risen by 0.08 x 3 = $0.24

Price of stock A at noon is 13.45 + 0.24 = $13.69

Thereafter stock A continues to increase by the same rate of $0.08 per hour
The equation to model stock A price starting at noon is
13.69 + 0.08x where x is the number of hours elapsed after 12 noon

Stock B price is $14.20 at 12 noon and decreases by $0.14 per hour
Equation to model stock B price after 12 noon is

14.20 - 0.14x where x is the elapsed time after 12 noon

For both prices to be the same after the same x hours, we have
13.69 + 0.08x = 14.20 - 0.14x

Solving for x will tell us how many hours it will take for both stock prices to be the same

Solving
13.69 + 0.08x = 14.20 - 0.14x

So the two stock prices will be the same 2.3 hours after 12 noon or about 2 hours and 18 minutes after 12 noon or roughly around 2:18pm

I got 18 minutes by multiplying 0.3 x 60 = 18

A rotation of 270° counterclockwise will map the blade formed by ΔFEG onto the blade formed by ΔHGI

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the first triangle be represented as ΔFEG

Let the second triangle be represented as ΔHGI

Now , for both the triangles to be similar , the mapping of the rotation of the blade should be rotated once in the clockwise or three times in the counterclockwise direction

So , for a rotation of 90° clockwise rotation: (x,y) becomes (y,-x)

So , for a rotation of 270° counterclockwise rotation: (x,y) becomes (y,-x)

Collecting all points in the plane where the gap between two fixed points and a fixed point is constant is known as a hyperbola.

With the foci on the y-axis and the x-axis serving as the hyperbola's centre, the graph of the equation y = k/x is a hyperbola. The y-axis serves as the hyperbola's centre of gravity, with the x-axis serving as its foci, on the graph of the equation xy = k.
