Find the value of X and 2x

Answer:

  24.98 units

Step-by-step explanation:

You want the perimeter of triangle ABC with vertices A(-5, 4), B(1, -2), and C(3,6).

The distance between two vertices can be found using the formula ...

  d = √((x2 -x1)² +(y2 -y1)²)

The  distance between A and B is ...

  d = √((1 -(-5))² +(-2 -4)²) = √(6² +(-6)²) = 6√2 ≈ 8.485

The attached spreadsheet performs the same calculation on all the pairs of points. (The distance from each point to the one below it is listed.)

The perimeter of the triangle is the sum of the segment lengths. That is also shown in the spreadsheet.

  P = AB +BC +CA

  P = 8.485 +8.246 +8.246 ≈ 24.98

The perimeter of triangle ABC is about 24.98 units.

The graph of the equation, y = -50x + 300, is given in the attachment below.

The equation of a line, where m is the slope or unit rate, and b is the y-intercept or starting value, is expressed as y = mx + b in the slope-intercept form.

Given the situation above, first determine the value of the starting value / y-intercept (b) and that of the slope / unit rate (m).

The starting value / y-intercept is b = 300.

The slope / unit rate is m =  - 50 [this is negative because the distance from home reduces as she drives at the speed of 50 mph]

To write the equation, substitute m = -50 and b = 300 into y = mx + b:

y = -50x + 300.

Thus, the graph of this equation, y = -50x + 300 is shown in the mage attached below.

The estimate expected mean time for the given activity E from the give table data is equal to 101days.

As given in the question,

Let optimistic time be represented by [tex]T_{o}[/tex]

Most like time be represented by [tex]T_{m}[/tex]

And Pessimistic time be represented by [tex]T_{p}[/tex]

Optimistic time for activity E is equal to  [tex]T_{o}[/tex] = 91

Most likely time for activity E is [tex]T_{m}[/tex] = 100

Ans Pessimistic time for activity E is [tex]T_{p}[/tex] = 115

Estimated expected mean time

= [tex]( T_{o} + 4T_{m} + T_{p} ) / 6[/tex]

= [ 91 + 4(100) + 115 ] / 6

Mrs. Jones will make 55 wax warmers when she produces 77 candles.

The given table shows the ratio of the number of candles to the number of wax warmers she makes.

Let's assume that "x" wax warmers will she make when she makes 77 candles

According to the given question, we can write the ratio would be as:

7 Candles : 5 Wax Warmers = 77 Candles : x Wax Warmers

⇒ 7/5 = 77/x

⇒ 7x = (77)(5)

Divided by 7 on both sides of the above equation,

⇒ x = (77)(5)/7

⇒ x = 11 × 5

Apply the multiplication operation, we get

⇒ x = 55

Thus, when she makes 77 candles, she will also produce 55 wax warmers.

Thus the answer is ‘ true’.

A population is any entire group that has at least one trait in common that is relevant to a given issue or experiment in statistics.

A probability sample is one that is drawn using a method of random selection that is compatible with the known odds for each member of the population to be selected, and that takes these probabilities into account when generating estimates from the sample.

If the chosen sample does not accurately reflect the total population of data, there has been a sampling error, which is a statistical error resulting from sampling.

On Thursday when the correct time is 5:00h, watch shows 4:24h.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

The watch is set at 11:00 h on Sunday.

Also, the watch loses 8 seconds in every hour.

To determine the time in watch on Thursday,

In one day total hours = 24 hours.

from Sunday 11:00 to Thursday 11:00

Total hours = 24 x 4 = 96 hours

And 11:00 to 5:00, total = 6 hours

Total hours = 96 + 6 = 102 hours

Since, watch loses 8 seconds in 1 hour

So in 102 hours watch losses = 102 x 8 = 816 seconds

816 seconds = 816/60 minutes = 13.6 minutes

The watch loses 13.6 minutes in 102 hours.

So the exact time will be, 4 : 24.

The line has a 17/5 slope and y has a value of 51 which will be (15, 51).

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

The general equation for every straight line is y = MX + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y -axis).

So, the water level rises by 17 cm in 5 minutes.

Then in 15  minutes, the water will rise by:

15 * 17/5

3*17

51

Then (x, y) will be (15, 51).

Obtaining the slope as follows:

Formula: m = y1 - y2/x1 - x2

m = y2 - y1/x2 - x1

m = 17  - y/5 - x

m = 17/5

Therefore, the line has a 17/5 slope and y has a value of 51 which will be (15, 51).

The rate of change in the attendance of students between 2018 and 2021 is 1.24.

The term "rate of change" (ROC) describes the rate at which something changes over time.

Thus, it is not the number of individual changes themselves but rather the acceleration or deceleration of changes (i.e., the rate).

The rate of change is a tool used in finance to comprehend price returns and spot trend momentum.

Divide the change in y-values by the change in x-values to determine the average rate of change.

Identifying changes in measurable values like average speed or average velocity calls for the knowledge of the average rate of change.

So, according to the given table:

The rates of change between 2018 and 2021 are:

It is a supposition that it is true if two points are equally far apart from a third point and the three points are collinear.

If three or more points lie on a single straight line, they are said to be collinear. An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two points determine a line, two points are trivially collinear.

Collinear points are those that are situated along a  identical straight line.

The supposition is correct since all three points are located on the same line.

if the two points create a straight angle that includes the third point, then the conjecture is true.

If the two points do not create a straight angle with the third point, then the conjecture is false.

Answer: He will work for 19 days.

Step-by-step explanation:

If Nicholas has 234 dollars and the computer he wants to put is 899 dollars, you have to subtract to see how much he has to take the loan from his parents in order to buy the computer.

899 - 234 = 665

He took a loan of 665 dollars from his parents

To figure out how many days he needs to work to pay that amount, you divide the amount he earns each day with the amount of loan he took.

So 665 divided by 35 = 19

He has to work 19 days to pay off the 665 dollar loan he took from his parents.

We can check this answer by multiplying 35 x 19 , which equals to 665.

Answer: x = 25

Step-by-step explanation:

(x-7) = 36/2

x-7 = 18

x = 18 +7

x = 25

Answer: x = 1 and x = 13.

Step-by-step explanation: To solve the equation (x - 7)^2 = 36, we can first rewrite the equation as x^2 - 14x + 49 = 36.

Next, we can rewrite the equation as x^2 - 14x + 13 = 0.

To solve for x, we can then use the quadratic formula:

x = (-b +/- sqrt(b^2 - 4ac)) / (2a)

where a = 1, b = -14, and c = 13.

Substituting these values into the formula, we get:

x = (14 +/- sqrt(14^2 - 4(1)(13))) / 2

x = (14 +/- sqrt(196 - 52)) / 2

x = (14 +/- sqrt(144)) / 2

x = (14 +/- 12) / 2

The values of x are therefore 1 and 13.

Therefore, the correct answer is x = 1 and x = 13.
