A junction is a place where two lines come together or cross. In the illustration above, "point K is the intersection of line segments PQ and AB" is what we would state. The phrase "the line segment PQ crosses AB at position K" is another option.

Keep in mind that two line segments do not always need to intersect. In the illustration above, move point B higher until the intersection of the two line segments disappears. However, keep in mind that lines (as opposed to line segments) continue indefinitely in both directions, thus unless they are absolutely parallel, they will always cross someplace.

The range did usage vary​ over from 823.81 to 2461.97 kilowatt-hours.

Kilowatt-hours are units of energy that represent one kilowatt of electricity for one hour (SI symbol: kWh or kWh; typically abbreviated as kWh). It is 3.6 megajoules in terms of standard units (MJ). For electrical energy supplied to customers by electric utilities, kilowatt-hours are a typical billing unit. The abbreviation "kWh," which is derived from the letters kilowatt and hour, stands in for the kilowatt-hour and is a commonly used abbreviation. In addition to being often used in commercial, academic, and scientific publications as well as in the media, it is also frequently employed by electric utility companies to bill consumers for energy delivered to them. One kilowatt (kW) sustained for one hour (multiplied by one) is equivalent to one kilowatt-hour, a composite unit of energy.

$64.34=6434 cents

$192.28=19228 cents

So 6434 cents  correspond to 6434/7.81

The difference between partitioning a directed line segment MN in a 2:7 ratio versus a 7:2ratio because of following

To understand this let us take the line segment MN which is of a length is divided into 9 equal parts. Here, we are dividing it into nine parts because the proportions 2 and 7 make a sum of 9.

When we divide the line segment MN in the ratio 2:7, the first two parts out of the nine from the left side are separated from the rest 7. This means that the first proportion from the left hand side of the line is smaller than the other.

Now, when we divide the line segment MN in the ratio7:2, the first seven parts out of the nine from the left side are separated from the rest two. This means that the first proportion from the left hand side of the line is larger than the other.

If Tom choose one marble then the probability that it will blue is 1/3.

According to the given question.

Total number of red marbles in a bag = 5

Total number of blue marbles in a bag = 4

Total number of yellow marbles in a bag = 3

So, the total number of marbles in a bag = 5 + 4 + 3 = 12

As we know that, the probability is the measure of the likelihood of an event to happen. It measures the certainty of the event.

According to the statement

We have to find that the equation using the polynomial function.

So, For this purpose, we know that the

A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation

From the given information:

The standard form with zeros 1,-1, 2, and 4:

Polynomial with Zeros 1, - 1, 2 and 4 can be expressed thus :

x = 1 : x - 1

x = - 1 :x + 1

x = 2 :x - 2

x = 4 :x - 4

Hence, we have :

(x - 1)(x + 1)(x - 2)(x - 4) = 0

We can then expand ;

(x - 1)(x + 1) = x² + x - x - 1 = x² - 1

(x² - 1)(x - 2) = x³ - 2x²-x + 2

(x³ - 2x² - x + 2)(x - 4)

A has no solution.

15x - 45 = 15x + 75

-45 = 75

in other words, when you add to the same thing different amounts, the result cannot be identical ever.

B has a solution

-45x - 45 = -75x + 75

-120x = 120

-x = 1

x = -1

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

2y + 50 + y + 10 = 180

3y + 60 = 180 ( subtract 60 from both sides )

3y = 120 ( divide both sides by 3 )

y = 40

2y = 2 × 40 = 80

y + 10 = 40 + 10 = 50

Answer:

y = 40

2y = 80

y + 10 = 50

Step-by-step explanation:

The sum of the angles of a triangle is 180°

Using values given,

2y + (y + 10) + 50 = 180

2y + y + 10 + 50 = 180

3y + 60 = 180

3y = 180-60 = 120

y = 120/3 = 40

2y = 80

y + 10 = 40 + 10 = 50

Step-by-step explanation:

The difference between the depths in February and July is 19 feet.

To find the difference between the depths in February and July, we need to subtract the depth in February from the depth in July.

The depth in February is given as |−6|, which is 6 feet, and the depth in July is given as |−25|, which is 25 feet.

Difference = Depth in July - Depth in February

Difference = 25 feet - 6 feet

Difference = 19 feet

Therefore, the difference between the depths in February and July is 19 feet.In February, the depth of the lake is given as |−6|, which represents the absolute value of -6. The absolute value of a number disregards its sign, so |−6| is equal to 6 feet.

In July, the depth of the lake is given as |−25|, which represents the absolute value of -25. Again, disregarding the sign, |−25| is equal to 25 feet.

To find the difference between the depths in February and July, we subtract the depth in February from the depth in July:

Difference = Depth in July - Depth in February

Difference = 25 feet - 6 feet

Difference = 19 feet

Therefore, the difference between the depths in February and July is 19 feet. This means that the lake experienced a change of 19 feet in depth between those two time points.

To find the scale factor:

When both the original dimensions and the new dimensions are known, the scale factor may be determined.

The following is a basic formula to determine a figure's scale factor:

Scale factor = Dimension of the new model ÷ Dimension of the actual car
