Answer:

Angle A is 20°

Step-by-step explanation:

The sum of the interior angles of a triangle is 180°.  

90 + 10x + x +13 = 180  Combine like terms

103 + 11x + 180  Subtract 103 from both sides

11x = 77  Divide both sides by 11

x = 7

Angle A is 13 + x.  X is 7, so 13 + 7 = 20

A graph which represent the solution to this inequality is: graph B.

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments:

Given the following inequality:

-1/4(12x + 8) ≤ -2x + 11

Opening the bracket, we have:

-3x - 2 ≤ -2x + 11

3x - 2x ≤ -11 - 2

x ≤ -13

Note: When the arrow points to the left and shaded, the inequality is either (≤).

In conclusion, a graph which represent the solution to this inequality is graph B.

The rational function with the given characteristics is [tex]f(x) = \frac{3x + 1}{x - 4} [/tex].

Any function that can be expressed mathematically as a rational fraction—an algebraic fraction in which both the numerator and the denominator are polynomials—is referred to as a rational function. The polynomials' coefficients don't have to be rational numbers,they can be found in any field K.

given that a vertical asymptote at x=-4.

A horizontal asymptote at y=3.

The denominator of the function cancels for this value and the numerator does not cancel at this value if the rational function has a vertical asymptote at x=4.

[tex]f(x) = \frac{p(x)}{(x - 4)} [/tex]

The degree of the numbered variable is equal to the degree of the denominator if the rational function has a horizontal asymptote at y=3, and the coefficient of the higher degree variable is three times larger.

Hence,

[tex]f(x) = \frac{3x + 1}{x - 4} [/tex]

Using the midpoint concept and the distance between two points, the correct statement is given by:

[tex]\sqrt{(0 - a)^2 + (2b - b)^2} = \sqrt{(2a - a)^2 + (0 - b)^2} = \sqrt{(a - 0)^2 + (b - 0)^2}[/tex]

The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.

Hence the coordinates of the midpoint of the hypotenuse are given as follows:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Hence the distance from the midpoint of the hypotenuse to any vertex is given by:

[tex]\sqrt{(0 - a)^2 + (2b - b)^2} = \sqrt{(2a - a)^2 + (0 - b)^2} = \sqrt{(a - 0)^2 + (b - 0)^2}[/tex]

Step-by-step explanation:

The word Inverse is used here because as the speed of traveled goes on increase, then the amount of time it takes to travel a particular distance will decrease .

The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity.

Let say if x and y are two values and k is a constant value, then

According to inverse variation

k = xy or y = k/x

In the question here, when we double your speed, it takes half as much time to reach the destination. The word Inverse is used here because as the speed of traveled goes on increase, then the amount of time it takes to travel a particular distance will decrease .

Answer:

y = 3 and x = 4

Step-by-step explanation:

Let's solve your system by substitution.

6x+5y=39;3x+5y=27

Step: Solve6x+5y=39for x:

6x+5y=39

6x+5y+−5y=39+−5y(Add -5y to both sides)

6x=−5y+39

6x/6=−5y+39/6

(Divide both sides by 6)

x=−5/6y+13/2

Step: Substitute −5/6y+13/2 for x in 3x+5y=27:

3x+5y=27

3(−5/6y+13/2)+5y=27

5/2y+39/2=27(Simplify both sides of the equation)

5/2y+39/2+−39/2=27+−39/2

(Add (-39)/2 to both sides)

5/2y=15/2

5/2y/5/2=15/2/5/2

(Divide both sides by 5/2)

y=3

Step: Substitute 3 for y in x=−5/6y+13/2:

x=−5/6y+13/2

x=−5/6(3)+13/2

x=4(Simplify both sides of the equation)

Two consecutive asymptotes are θ = - π / 20 and θ = 3π / 20 and the period is π / 5.

In this question we must look for two consecutive vertical asymptotes related to a trigonometric function. A function becomes undefined when its denominator is zero. Now we proceed to simplify the expression by trigonometric formulas:

y = 4 · csc (5θ - 3π / 4)

y = 4 / sin (5θ - 3π / 4)

y = 4 / (sin 5θ · cos 3π / 4 - cos 5θ · sin 3π / 4)

y = 4 / [(- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ]

The function is undefined for (- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ = 0:

(- √2 / 2) · sin 5θ - (√2 / 2) · cos 5θ = 0

(- √2 / 2) · sin 5θ = (√2 / 2) · cos 5θ

- sin 5θ = cos 5θ

tan 5θ = - 1

5θ = - π / 4 + i · π

θ =  - π / 20 + i · π / 5

θ = (π / 5) · (- 1 / 4 + i)

There are two consecutive asymptotes:

i = 0

θ = - π / 20

i = 1

θ = 3π / 20

And the period is ΔT = 3π / 20 - (- π / 20) = π / 5.

Answer: 0.22

Step-by-step explanation:

26.40/120

0.22

0.22 x 120 = 26.40

Step-by-step explanation:

I guess, the equation is meant to be in slope-intercept form :

y = ax + b

"a" is the slope, "b" is the y intercept (the y value when x = 0).

in a situation like this, where we have the slope and one point of the line, we can start with the point-slope form

y - y1 = a(x - x1)

"a" is again the slope, and (x1, y1) is the given point.

and then we transform this over to the slope-intercept form.

so, in our case here

y - 2 = 5/6 × (x - 5) = 5x/6 - 25/6

let's simplify this by multiplying everything by 6 :

6y - 12 = 5x - 25

6y = 5x - 13

y = 5/6 x - 13/6

or

y = 1/6 × (5x - 13)

Given data,

A piece of brass has a volume v cm'.

there were 6 cm'

mass would be 200 g

So,

We can write,

                       volume V = 6cm

                brass mass M = 200g

                        Find density d.

Define Density :

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centi meter.

                                  d = M/V

Where,

M: It is the mass

V: It is the volume

According to the data of the statement we have:

                                [tex]V = 6 cm^{1}[/tex]

                                [tex]M = 200g[/tex]

So, the density is given by:

                                d = M/V

                                d = [tex]\frac{200g}{6cm^{1} }[/tex]

                                d = [tex]33.33\frac{g}{cm^{1} }[/tex]

Therefore,

The density of the brass ornament is d = [tex]33.33\frac{g}{cm^{1} }[/tex]

Answer:

D.

Step-by-step explanation:

Hey there!

In order to find which description of the graph matches the problem, we must first create an equation or an inequality

So, we need to find how much more people the company needs to reach their goal to generate at least $7,300 in monthly revenue

We know that each person adds $300 to the already total of $5,500 per month

Now we can form the equation with this knowledge

[tex]300x + 5,500 \geq 7,300[/tex] where x is the number of people

Now we can simplify the equation

[tex]300x\geq 7500 - 5500\\ 300x\geq 2000\\x\geq 6.67[/tex]

Since we cannot have 6.67th of a person, we must round down because it means that we need more than 6 people

If we round up, it means that you need more 7 people in order to get $7,300 which isn't true

This means, you need more than 6 salespeople per month in order to meet the monthly quota of $7,300 in monthly revenue

Now that we know this, we can make a graph, or find the correct description of the graph

Since they need more than 6 people, the dot that sits on 6 in the number line will not be filled in, indicating that you need more than 6 salespeople

And since we need MORE, not LESS, the line will be pointing to the right

So, the correct answer would be D.

If the total price is $307.32 and tip rate is 20%, the original price given the total amount and tip rate is $256.10

What is the sum of the percentage of the original price and tip rate?

First and foremost, the tip rate is an added layer on the original price of 100%, which means that when the original price and the tip rate are added together, it gives 120%, hence, the total price of $307.32 is 120% of the original price

120% of original price=$307.32

1% of original price=$307.32/120

1% of original price=$2.561

100% of original price=$2.561*100

this is used in economics and for planning to maximize profits and minimize costs.

It depends on what you mean "simplify". Chances are the goal here is to resolve any exponents that are improper fractions, meaning we don't want exponents larger than 1, like 4/3, for instance, but smaller than 1, like 2/3, is okay.

Now, by the distributive property of exponentiation,

[tex]\left(x^4 y\right)^{2/3} = \left(x^4\right)^{2/3} y^{2/3}[/tex]

Since [tex](x^a)^b = x^{ab}[/tex], we have

[tex]\left(x^4 y\right)^{2/3} = x^{4\cdot2/3} y^{2/3} = x^{8/3} y^{2/3}[/tex]

Convert the improper fraction to a mixed number.

[tex]\dfrac83 = 3 + \dfrac23[/tex]

Then we can write

[tex]x^{8/3} = x^{3 + 2/3} = x^3 x^{2/3}[/tex]

since [tex]x^{a+b}=x^ax^b[/tex].

Finally, we group together the factors with the same power.

[tex]\left(x^4 y\right)^{2/3} = x^3 x^{2/3} y^{2/3} = \boxed{x^3 (xy)^{2/3}}[/tex]
