Answer:

The required equation is [tex]\angle W+3\angle W=180^{\circ}[/tex].

Step-by-step explanation:

Given information: WXYZ is a parallelogram, W and X are adjacent interior angles and measure of X is three times the measure of W.

According to the properties of parallelogram, the two adjacent interior angle are supplementary angle and their sum is 180 degrees.

[tex]\angle W+\angle X=180^{\circ}[/tex]            .... (1)

It is also given that the measure of X is three times the measure of W.

[tex]\angle X=3\angle W[/tex]

Substitute this value in equation 1.

[tex]\angle W+3\angle W=180^{\circ}[/tex]

[tex]4\angle W=180^{\circ}[/tex]

[tex]\angle W=45^{\circ}[/tex]

Substitute this value in equation 1.

[tex]\angle W=135^{\circ}[/tex]

Therefore the required equation is [tex]\angle W+3\angle W=180^{\circ}[/tex].

Answer:

The answer would be A.) 21 gallons.

Step-by-step explanation:

1.) The first thing you need to do is see how many miles per gallon the van is using by doing 168/14= 12.

2.) Then, you would apply this to the amount need to travel by doing 252/12= 21, meaning the answer is in fact A.) 21 gallons.

To find out how many gallons of gas a van would need to travel 252 miles, given that it travels 168 miles on 14 gallons, you can use a simple ratio and proportion calculation. This yields that the van would need 21 gallons to travel 252 miles.

The subject here is the mileage of a van, which is a problem of ratio and proportion. Given that the van travels 168 miles on 14 gallons of gas, we can find out how much it would need to travel 252 miles. We set up the proportion as follows:

168 miles / 14 gallons = 252 miles / X gallons

To find X (the unknown), we cross multiply:

168 * X = 252 * 14

After solving this equation, we find that X equals 21. Therefore, the van would need 21 gallons to travel 252 miles.

Answer:

n = S/180 + 2

Step-by-step explanation:

S = 180(n - 2)

First, divide both sides by 180.

S/180 = n - 2

Now add 2 to both sides.

S/180 + 2 = n

n = S/180 + 2

Answer:

n = (S/180) + 2

Step-by-step explanation:

You are solving for n, and so isolate the variable. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS:

PEMDAS =

Parenthesis

Exponent ( & roots)

Multiplication

Division

Addition

Subtraction

---------------------------------------------------------------------------------------------------------

First, divide 180 from both sides

(S)/180 = (180(n - 2))/180

S/180 = n - 2

Next, to isolate the variable (n) completely, add 2 to both sides

(S/180) (+2) = n - 2 (+2)

(S/180) + 2 = n

n = (S/180) + 2 is your answer

Answer:

Ambitious

In this case, you have to multiply the price of the one way journey ($2.65) by 8 (as this is the number of individual journeys made in one week. It's gives you $21.20. As he has 1 bottle of water at $1.45 each day for four days, you have to multiply these together, giving you $5.80 You then have to add together $21.20 and $5.80, giving you $27. Therefore, it costs Edgar $27 a week

Step-by-step explanation:

Answer:

$27.00

Step-by-step explanation:

To ride the bus to and from work costs

2* 2.65 = 5.30  for 1 day

He rides the bus 4 days a week

4 * 5.30 = 21.20      for 4 days

He buys a bottle of water on the way to work 4 days a week

4 * 1.45 = 5.80  for 4 days

Cost to ride the bus = bus fare for 4 days + water for 4 days

                                    = 21.20 + 5.80

                                     = 27.00

4 (2*2.65+ 1.45) = 27

Answer:

The common difference of the arithmetic sequence is 14.

Step-by-step explanation:

The arithmetic sequence is defined as

x:   1     2    3    4    5

y:  11   25  39  53   67

The common difference of the arithmetic sequence is

[tex]d=\frac{y_2-y_1}{x_2-x_1}[/tex]

Consider any two points, i.e.,(1,11) and (2,25).

[tex]d=\frac{25-11}{2-1}[/tex]

Answer:

arcBC = 148° ; ∠ACD = 26°

Step-by-step explanation:

Note that these two problems given to us uses the "inscribed angle theorem", which states that the angle is 1/2 the measurement of a central angle. Keep in mind that the central angle's measurement is the same as it's projected arc, and so the inscribed angle would also be 1/2 the measurement of the projected arc. This works vice versa too. The projected arc would be twice as large as the inscribed angle's measurement.

Final answer is x= -0.76 and y=2.57.

Step-by-step explanation:

We have been given two functions [tex]f(x)=x^3+3[/tex] and

[tex]g(x)=x^2+2[/tex]

Now question says to graph the given functions [tex]f(x)=x^3+3[/tex] and

[tex]g(x)=x^2+2[/tex] using some graphing tool. Then zoom as per requirement so that you can see the intersection point and read that point from graph which should be correct up to hundredth decimal place.

I'm using Desmos graphing calculator. Just type both functions then it will create graph for you. Click on intersection point as you can see in the attached picture. They intersect at point (-0.755,2.57).

Hence final answer is x=-0.76 and y=2.57.

Answer:

Step-by-step explanation:

The given functions are

[tex]f(x)=x^{3}+3\\ g(x)=x^{2} +2[/tex]

If we wanna find [tex]f(x)=g(x)[/tex] we can just graph and see such point, or we can do some algebra to find it. This problem, specifically, asks an answer using a graphic method. The graph with both functions is attached.

You can see that the interception point is (-0.755, 2.57), which rounded to the nearest hundred is (-0.76, 2.57). At this point the functions are equal ([tex]f(x)=g(x)[/tex]), that's what an interception means.

We obtained this point by just left-clicking on the interception point, as the problem indicates.

The area and the circumference of the circle are 28.26 square units and 18.84 units

Finding the area and the circumference of the circle

From the question, we have the following parameters that can be used in our computation:

Radius, r = 3 units

The area and the circumference of the circle are calculated using

Area = πr²

Circumference = 2πr

Substitute the known values into the equation

Area = 3.14 * 3² =  28.26

Circumference = 2 * 3.14 * 3 = 18.84

Hence, the area and the circumference of the circle are 28.26 square units and 18.84 units

Question

Find the area and the circumference of the circle

Answer:

1, 2, 3

Step-by-step explanation:

solve the inequality by dividing both sides by 2, hence

n ≤ 3

3 = 3 and 1, 2 < 3

hence 1, 2 and 3 all make the inequality true

Answer:

A = pi/2

Step-by-step explanation:

Area of a sector is given by

A = 1/2 r^2 theta when theta is given in radians

We know the area of the circle (pi * r^2) so we multiply by pi/pi

A = 1/2  pi/pi r^2 theta

A = 1/(2* pi)  * pi r^2 theta  

   =  1/(2* pi)  * Ac theta   where Ac is the area of a circle

Substituting what we know  Ac = 9 pi and theta = 1/9 * pi

A    =  1/(2* pi)  * 9*pi  1/9 * pi

A = 1/(2* pi)  * pi^2

A = 1/2 * pi

A = pi/2

Answer:

Its [tex]\frac{\pi }{2}[/tex] .

Step-by-step explanation:

Because the work shown below will show you how:

[tex]\frac{\theta}{2\pi } = \frac{A_s}{A_c}\\\frac{1}{9} /2\pi = \frac{A_s}{9\pi } \\\frac{1}{18} = \frac{A_s}{9\pi } \\\frac{1}{18} * 9\pi = A_s\\=\pi/2[/tex]

Answer:

x=-2

Step-by-step explanation:

Given points are (-2,2) and (-2,-3).

Now we need to find equation of the line passing through the given points.

So let's begin by finding slope

[tex]m=\frac{\left(y_2-y_1\right)}{\left(x_2-x_1\right)}=\frac{\left(-3-2\right)}{\left(-2-\left(-2\right)\right)}=\frac{\left(-5\right)}{\left(-2+2\right)}=-\frac{5}{0}[/tex]

which is undefined. That means graph of the line must be vertical as you can see that in given points, x-value is not changing.

Equation of vertical line is given by x=k where k is the fixed value of x-coordinate.

x-coordinate is -2 in given points.

Hence final equation is x=-2.

Answer:

x=-2

Answer:

Wanda and Dave will catch each other in 54 seconds after Dave starts walking.

Step-by-step explanation:

Let Wanda and Dave catch each other when x be the time after Dave starts walking and y be the distance covered by them

It is given that Wanda started walking along a path 27 seconds before Dave and the constant speed of Wanda is 3 feet per second.

[tex]speed=\frac{distance}{time}[/tex]

[tex]3=\frac{y}{x+27}[/tex]

[tex]y=3(x+27)[/tex]

 [tex]y=3x+81[/tex]                          .... (1)

The constant speed of Dave is 4.5 feet per second.

[tex]4.5=\frac{y}{x}[/tex]

[tex]y=4.5x[/tex]                                .... (2)

Equate equation (1) and (2).

[tex]3x+81=4.5x[/tex]

[tex]81=1.5x[/tex]

Divide both sides by 1.5.

[tex]\frac{81}{1.5}=x[/tex]

[tex]54=x[/tex]

Therefore, Wanda and Dave will catch each other in 54 seconds after Dave starts walking.

Answer:

3(m - 32.97) = 3.09

Step-by-step explanation:

She started with m money for each of the three children.

A pair of pants costs $12.99. Each polo shirt costs $9.99.

A pair of pants and 2 polo shirts cost

$12.99 + 2 * $9.99 = $12.99 + $19.98 = $32.97

For each child, she had m money and spent $32.97.

For each child, she had m - 32.97 money left.

For the three children, the amount of money left was 3(m - 32.97).

We are told that for the three children, the amount of money left is $3.09.

That means that 3(m - 32.97) must equal $3.09.

The equation is:

3(m - 32.97) = 3.09

Answer:

The answer to your expression is 94.

Step-by-step explanation:

Given Expression -> 3 ( 7 - 5 ) + 8 ( 9 + 2 )

Order of Operations Parenthesis -> 3 ( 2 ) + 8 ( 11 )

Multiplcation Left to Right -> 6 + 8 ( 11 )

Multiplcation Left to Right -> 6 + 88

Addition -> 94

Final answer:

To evaluate the expression 3(7 - 5) + 8(9 + 2), we first solve the expressions within parentheses, then multiply, and finally add the results to get the answer, which is 94.

Explanation:

To evaluate the expression 3(7 - 5) + 8(9 + 2), we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Then we add the results of the multiplications: 6 + 88.

So, the expression 3(7 - 5) + 8(9 + 2) evaluates to 94.

Answers:

1) Given

2) angle 2 ** see note below

3) angle 3 ** see note below

4) converse of alternate exterior angle theorem

note: you can swap the answers for 2 and 3 and it doesn't matter

========================================================

Explanations:

1) This is given so we just simply state "given". It seems silly to repeat what is given, but this is how you start any geometry proof.

2 & 3) The answers here are angle 2 and angle 3 because they are both interior angles (on the inside of the parallel lines m and L) and they are on alternate sides of the transversal line q. So they are both alternate interior angles and are congruent due to line L parallel to line m (alternate interior angle theorem)

4) If you have a pair of parallel lines, then the alternate exterior angle theorem says that alternate exterior angles are congruent. Going in reverse, the converse of this theorem says that having a pair of congruent alternate exterior angles (angle 1, angle 2) leads to the lines being parallel (p and q).
