What is the linear pair angles?

Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°.

We have,

Angles:

6x° + 35°

z°

8x° + 51°

To find the values of x and z

from the given figure

Linear pair angles:

6x° + 35° + 8x° + 51° = 180

14x° + 86° = 180

14x° = 180° - 86°

14x° = 94°

x° = 94°/14°

x° = 6.71°

Vertically opposites angles are equal

6x° + 35° = z°

z° =  6( 6.71°)° + 35

z° = 40.26 + 35

z° = 75.26°

Hence, the value of x and z are x° = 6.71°, z° = 75.26° simulataneously.

The equation of the line that passes through point (8, -7) and parallel to the line x + 2y = 18 is

A linear function consists of functions where the variables has exponents of 1.

The graph of linear functions is a straight line graph and the relationship is expressed in the form.

y = mx + c

definition of variable

y = output variable

m = slope

x = input variable

c = y intercept

x + 2y = 18

rewriting gives : y = -x/2 + 9

when the line is parallel the slope is equal hence the slope of the line is -1/2.

using the point slope formula for point (8, -7) which is

(y - y') = m(x - x')

(y + 7) = -1/2(x - 8)

y + 7 = -x/2 + 4

y = -x/2 - 3

the equation of the line is y = -x/2 - 3

Sample is biased. Based on her findings, Arianna revealed the percentage in her state after polling 600 residents of her city. Thus, the sample fails to accurately reflect the population. Option (4) is correct.

When some members of a population are systematically more likely to be chosen in a sample than others, this is known as sampling bias. What makes sampling bias significant? Sampling bias poses a risk to external validity since it restricts the applicability of your findings to a larger population. When some population members have a higher or lower sampling probability than others, the sample is biased.

This includes choosing or sampling people according to their hobbies, gender, or age. Therefore, a fair or impartial sample must be representative of the entire population under investigation. When a research study design fails to gather a representative sample of a target population, the phenomenon known as sampling bias takes place. This usually happens as a result of the respondents' selection criteria not capturing a broad enough sampling frame to include all points of view.

Since, We catch the other car if our speed of our car is 60mph.

When you catch up, the distance traveled is the same

Let us consider x as the velocity.

Therefore, our velocity is x + 10

We know that:

Distance = rate x time

According to the question:

r = uncle's rate

30 min = 30/60 hr = uncle's time

25 min = 25/60 hr =  your time

and

Uncle's distance = Your distance

Now,

(r)(30/60) = (r + 10)(25/60)

⇒ (r)(1/2) = (r + 10)(5/12)

⇒ r/2 = 5r/12 + 50/12

Answer:

80 kg

Step-by-step explanation:

To find the mass of the skater, you can use the formula for centripetal force:

F_centripetal = m * v^2 / r

Where F is the centripetal force, m is the mass of the object, v is the velocity of the object, and r is the radius of the circular path.

Plugging in the values you know, you get:

720 N = m * (15 m/s)^2 / 25 m

Solving for m, you find that the mass of the skater is:

m = 720 N * 25 m / (15 m/s)^2

= 720 N * 25 m / 225 m^2/s^2

= 80 kg

So the mass of the skater is approximately 80 kilograms.

Explanation:

x = amount she travels on each of those three remaining days

3x = total amount traveled over those three remaining days

3x+24 = total amount traveled over the four days

3x+24 = 120 miles total

This equation is in the form px+q = r where:

Let's solve for x. We follow PEMDAS in reverse to undo what's happening to x, so we can isolate it.

3x+24 = 120

3x+24-24 = 120-24 .... subtract 24 from both sides

3x = 96

3x/3 = 96/3 .... divide both sides by 3

x = 32

Triana must travel 32 miles per day for those remaining three days.

Doing so means she travels 3x = 3*32 = 96 miles over those three remaining days. Then add on those 24 miles traveled on the first day to get 96+24 = 120 miles total. This helps confirm the answer.

Another way to confirm the answer is to plug x = 32 into 3x+24 = 120. After simplifying both sides, you should get 120 = 120 which is a true statement.

The equivalent expression could be 4×3·4×4−s

Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value for the variable, two algebraic expressions that are equivalent have the same value.

Think about the numbers 3²+1 and 5×2. They both add up to 10. These two expressions are equivalent, so to speak.

Let's now have a look at some expressions with variables, such 5x+2.

It is possible to rewrite the expression as 5x+2=x+x+x+x+x+1+1.

The right side of the equation can be regrouped to 2x+3x+1+1, x+4x+2, or another combination. When the same value is used as x, all of these equations have the same result. These two expressions are equivalent, so to speak.

When two expressions have the same value regardless of the value of the variable(s) they contain, they are said to be equivalent.

Here, 4×3=12 and 4×4=16

therefore, 4×3·4×4−s is equal to the expression 12⋅16−s

The value of baseball card has increased by 160(%) percentage.

What is the percentage?

A number or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word per cent means. The letter "%" stands for it.

Increase = New Number - Original Number

Then: we divide the increased number by the original number and multiply by 100.

Therefore, % increase = (Increase ÷ Original Number)× 100.

Given, the new price of a baseball card = $13

The original price of a baseball card = $5

Then from the above definition,

Increase = 13-5 = 8

% increase = (8/5)*100 = 160%

Hence, its value has increased by 160 percentage.

Therefore,

m∠ABD = 100 degrees

m∠ABC = m∠2

m∠CBD = m∠1

3. 32, 28, 30

4. 38, 142

Step-by-step explanation:

3. (x + 3) + (x - 1) + (x + 1) = 90

3x + 3 = 90

3x = 87

x = 29

angle 1: x + 3 = 29 + 3 = 32

angle 2: x - 1 = 29 - 1 = 28

angle 3: x + 1 = 29 + 1 = 30

4. x + (x + 104) = 180

2x + 104 = 180

2x = 76

x = 38

angle 1: x = 38

angle 2: x + 104 = 38 + 104 = 142

Answer:

Step-by-step explanation:

To solve this equation, you can use the process of polynomial algebra.

First, you can rearrange the terms on the left side of the equation so that all the terms with an x^2 coefficient are on one side and all the other terms are on the other side. You can do this by adding x^2 to both sides of the equation:

5x^2 - 2x - 6 + x^2 = -x^2 + 6x + x^2

This gives you:

6x^2 - 2x - 6 = 6x

Now, you can rearrange the terms on the right side of the equation in the same way:

6x^2 - 2x - 6 = 6x^2 - 6x

To solve for x, you can now use the process of polynomial algebra to combine like terms on each side of the equation. This gives you:

6x^2 - 2x - 6 = 6x^2 - 6x

Combining like terms on the left side of the equation gives you:

6x^2 - 6x - 6 = 6x^2 - 6x

Combining like terms on the right side of the equation gives you:

6x^2 - 6x - 6 = 6x^2 - 6x

Now, you can subtract 6x^2 - 6x from both sides of the equation to obtain:

-6x - 6 = 0

Dividing both sides of the equation by -6 gives you:

x + 1 = 0

Finally, you can solve for x by subtracting 1 from both sides of the equation, which gives you:

x = -1

Therefore, the solution to the original equation is x = -1.
