The value of x that makes m ║n is 60 degree.

What is consecutive interior angles?

Pairs of angles that are between two lines and on the same side of the line that cuts through the lines are referred to as consecutive internal angles.

The "consecutive interior angle theorem" asserts that each pair of consecutive interior angles is supplementary, meaning that the sum of the consecutive interior angles equals 180°, if a transversal intersects two parallel lines.

Here to make m ║n  the angles x and 2x are consecutive interior angles.

Since consecutive interior angles are supplementary.

So,

x + 2x = 180

3x = 180

x = 180/3

x = 60 degree.

Therefore, the value of x is 60 degree that makes m ║n.

10 blocks are the shortest distance between Caroline and Mattie's homes.

Given data,

Caroline steps outside and makes a 6 block trek to the north. To go to Mattie's house, she does a turn and travels 8 blocks to the east.

To get the shortest distance between Caroline and Mattie's houses we need to it as a triangle and apply the Pythagorean theorem.

Pythagorean theorem:

The well-known geometric axiom is that the hypotenuse (the side across from the right angle) of a right triangle is equal to the sum of the squares on its legs. Or, in popular algebraic form, a² + b² = c².

The shortest distance (c);

Let, a = 6

      b = 8

⇒ a² + b² = c²

   6² + 8² = c²

   36 + 64 = c²

   c = [tex]\sqrt{100}[/tex]

   c = 10

Therefore, the shortest distance between Caroline’s and Mattie’s houses is 10 blocks.

The correct options are first, second and fourth

What are parallel lines?

Two lines are said to be parallel if on extending them indefinitely, they will never intersect

Here,

From the figure,

For the first option,
m∠1=m∠5 [Corrosponding angles are equal]

First option is correct

For the second option,
m∠7=m∠11 [Corrosponding angles are equal]

Second option is correct

For the third option,
m∠5 ≠ m∠12 [ c is not parallel to b]

Third option is wrong

For the fourth option,
m∠4 = m∠5 [Alternate interior angle are equal]

Flour is defined as a food product that is the main ingredient for baking of different recipes such as cakes, breads, plate pies just to mention a few.

The amount of flour needed by Karina for the recipe= 3/5 = 0.6.

The amount of flour owed by the mother = 3/7 = 0.45

The difference between the available flour = 0.6 - 0.45 = 0.15

The answer, Arianna's battery, as a percentage, 3.75t hours after Arianna left her house.

What is percentage?

A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. Percentage refers to one in a hundred. The % sign is used to denote it.

The initial charge of Arianna's phone = 45%

now the charge remaining in Arianna's battery = 15%

If after 4 hours of leaving her house, the battery had 15% remaining battery life, then the battery is discharging at the rate of ( 15% / 4 hours)

=3.75% per hour.

Thus, the charge remaining in Arianna's battery after she left her house will be, B = 3.75t

Step-by-step explanation:

first you find the slope which is 5/4 then you do y=mx+b but replace the y and the x with points on the line giving you 2=5/4•4+b then you solve for b and get -3 giving you your answer.

Answer: -5/4x+7

Step-by-step explanation:

1)First find the slope passing through (8,-3) (4,2) using this formula

y2-y1/x2-x1 (this: 2--3/4-2) to get -1.25 or -5/4. this is your slope.

2) Then to get the y-intercept choose one of your points (doesn't matter which I chose (8,3) but you can choose any of the two) and create this formula y=mx+b.

3) Input your x and y from the point you chose and your slope (m) to create this -3=(8)+b.

4) Now solve for b. This should get you Postitve 7 (REMEMBER it is VERY IMPORTANT if you result is negative or positive. One mess up could make the whole thing wrong.)

5) Finally take your slope and y-intercept and put it together to get:

There are a total of seven different ways for eight individuals to sit around a circular table: (8-1)!=7!. We are using the concept of circular permutation.

By using circular permutation we have,

7!=5040

All of the seating is included in these 5040 ways. Given that everyone has the same two neighbors, regardless of whether they are left or right neighbors, two seating are said to be equal. To achieve the desired outcomes, we must divide the total number of methods by 2.

[tex]\left(sec(x) = \dfrac{1}{cos(x)}\right)[/tex]  and [tex]\left(csc(x) = \dfrac{1}{sin(x)}\right)[/tex] to give the following

trigonometric identity;

Trigonometric identities are equations of trig functions which are valid for all values of the input variable at which the expressions on both sides of the equality are defined.

The trigonometric expression in the question is simplified as follows;

[tex]\dfrac{tan( x)}{1+sec( x)} +\dfrac{1+sec( x)}{tan( x)} = \dfrac{tan( x)}{1+\dfrac{1}{cos(x)} } +\dfrac{1+\dfrac{1}{cos(x)}}{tan( x)}[/tex]

[tex]\dfrac{tan( x)}{1+\dfrac{1}{cos(x)} } +\dfrac{1+\dfrac{1}{cos(x)}}{tan( x)} = \dfrac{cos(x)\times tan( x)}{cos(x)+1} } +\dfrac{cos(x)+1}{cos(x)\times tan( x)}}[/tex]

[tex]\dfrac{cos(x)\times tan( x)}{cos(x)+1} } +\dfrac{cos(x)+1}{cos(x)\times tan( x)}} = \dfrac{sin(x)}{cos(x)+1} } +\dfrac{cos(x)+1}{sin( x)}}[/tex]

[tex]\dfrac{sin(x)}{cos(x)+1} } +\dfrac{cos(x)+1}{sin( x)}} = \dfrac{sin^2(x)+(cos(x)+1)^2}{sin( x)\cdot (cos(x)+1)} }[/tex]

[tex]\dfrac{sin^2(x)+(cos(x)+1)^2}{sin( x)\cdot (cos(x)+1)} }=\dfrac{sin^2(x)+cos^2(x)+2\cdot cos(x)+1}{sin( x)\cdot (cos(x)+1)}[/tex]

[tex]\dfrac{2\cdot cos(x)+2}{sin( x)\cdot (cos(x)+1)} =\dfrac{2\cdot (cos(x)+1)}{sin( x)\cdot (cos(x)+1)} = \dfrac{2}{sin( x)}[/tex]

[tex]\dfrac{2}{sin( x)} = 2\cdot csc(x)[/tex]

Answer:

Step-by-step explanation:

If the number B of federally insured banks could be approximated by B ( t ) = − 329.4 t + 13747 from 1985 to 2007 where t = 0 correspond to year 1985

In order to determine the amount of federally insured banks that were there in 1990, we will first calculate the year range from initial time 1985 till 1990

The amount of time during this period is 5years. Substituting t = 5 into the modeled equation will give;

B ( t ) = − 329.4 t + 13747

B(5) = -329.4(5) + 13747

B(5) = -1647+13747

B(5) = 12100

This shows that there will be 12100 federally insured banks are there in the year 1990.
