Answer:

[1, 4]; 1 = m

Step-by-step explanation:

According to the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE terms of what they really are, so in this case, the coordinates are [1, 4]. Now, the rate of change [slope] is 1 because an invisible coefficient is always assumed to be 1.

I am joyous to assist you anytime.

Answer:

The slope of the line is 1 and it passes through the point (1,4).

Step-by-step explanation:

If a line passes through a points [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is

[tex]y-y_1=m(x-x_1)[/tex]            .... (1)

The given equation of line is

[tex]y-4=(x-1)[/tex]                .... (2)

We need to find the slope and the coordinates of a point on the given line.

On comparing (1) and (2) we get

[tex]m=1[/tex]

[tex]x_1=1[/tex]

[tex]y_1=4[/tex]

Therefore, the slope of the line is 1 and it passes through the point (1,4).

Answer:2 to 4%

Step-by-step explanation:

your odds are 1/30 then your persentage would be 3 percent so your range of 20 to 30 students would be 2 to 4 percent chances

Final answer:

The estimated probability of a specific student's name being drawn from a class of 20-30 students is 4% or 1 in 25.

Explanation:

The probability of a specific student's name being drawn from a class with a number of students between 20 and 30 can be estimated by taking the inverse of the average of the maximum and minimum possible number of students. We calculate the average by adding 20 (the minimum) to 30 (the maximum) and dividing by 2, resulting in an average class size of 25 students.

To estimate the probability of drawing any one student's name, we take the inverse of 25, which is 1/25 or 0.04. Thus, the estimated probability is 4% that any particular student would be chosen in a random draw from a class size between 20 and 30 students.

Answer:

300, 600, 300.

Step-by-step explanation:

324:  The tens digit is 2 so we do nothing to the hundreds digit so its 300.

558:  The tens digit is 5 so we round up the 5 . So it is 600.

In a similar way 256 becomes 300.

Answer:

300, 600, 300

Step-by-step explanation:

When you round a number up by the nearest 100. The digit in the tens place must be equal to or more than 5.

For example: 250 is rounded up to 300, but 240 can not be rounded up to 300.

When you have a number like 240, it can only be rounded down to 200

324 is rounded down to 300 because the tens place digit is less than 5

558 is rounded up to 600 because the tens place digit is higher than 5.

256 is rounded up to 300 because the tens place digit is 5.

Hope this helped.

EF is a segment so it's a line with the end points as E and F. Line RS bisects(cuts in half) line EF. Then where the two lines meet is where A is.

To draw segment EF so that it bisects segment RS and mark their intersection point A, follow these steps:

Draw segment RS. This will be your starting line segment.

Find the midpoint of segment RS. To do this, measure the length of RS and mark the point that is exactly halfway between R and S. Let's call this point M.

Draw a straight line segment EF that passes through point M. This line segment will bisect segment RS.

Where segment EF intersects segment RS, mark the point of intersection as point A.

Answer:

The value of x is 2

Step-by-step explanation:

* Lets explain how to find a distance between 2 points

- If the endpoints of a segment are [tex](x_{1},y_{1})[/tex] and

 [tex](x_{2},y_{2})[/tex] is [tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

- Triangle ABC has a perimeter of 12 units

∵ The perimeter of any triangle is the sum of lengths of its sides

∴ P Δ ABC = AB + BC + AC

* Lets find the length of the three sides

∵ A = (x , 2) , B = (2 , -2) , C = (-1 , 2)

∵ [tex]AB=\sqrt{(2-x)^{2}+(-2-2)^{2}}[/tex]

∴ [tex]AB=\sqrt{(2-x)^{2}+(-4)^{2}}[/tex]

∴ [tex]AB=\sqrt{(2-x)^{2}+16}[/tex]

∵ [tex]BC=\sqrt{(-1-2)^{2}+(2--2)^{2}}[/tex]

∴ [tex]BC=\sqrt{(-3)^{2}+(4)^{2}}[/tex]

∴ [tex]BC=\sqrt{9+16}[/tex]

∴ [tex]BC=\sqrt{25}[/tex]

∴ BC = 5

∵ [tex]CA=\sqrt{(x--1)^{2}+(2-2)^{2}}[/tex]

∴ [tex]CA=\sqrt{(x+1)^{2}+(0)^{2}}[/tex]

∴ [tex]CA=\sqrt{(x+1)^{2}}[/tex]

- The √ is canceled by power 2

∴ CA = (x + 1)

∵ AB + BC + CA = 12

∴ [tex]\sqrt{(2-x)^{2}+16}[/tex] + 5 + (x + 1) = 12

- Add 5 and 1

∴ [tex]\sqrt{(2-x)^{2}+16}[/tex] + 6 + x = 12

- subtract 6 and x from both sides

∴ [tex]\sqrt{(2-x)^{2}+16}[/tex] = (6 - x)

- To cancel (√ ) square the two sides

∴ (2 - x)² + 16 = (6 - x)²

- Simplify the two sides

∴ [(2)(2) + (2)(2)(-x) + (-x)(-x)] + 16 = (6)(6) + (2)(6)(-x) + (-x)(-x)

∴ 4 - 4x + x² + 16 = 36 - 12x + x²

- Subtract x² from both sides

∴ 20 - 4x = 36 - 12x

- Add 12x to both sides and subtract 20 from both sides

∴ 12x - 4x = 36 - 20

∴ 8x = 16

- Divide both sides by 8

∴ x = 2

* The value of x is 2

Answer:

50 hours.

Step-by-step explanation:

First I found how how much the man was paid in a week for the base 40 hours which was 384. Then i subtracted that from the wage from the week so i could just have the overpay amount which was 144. I then multiplied 9.6 by 1.5 to get the hourly pay for overtime and god 14.4 dollars an hour. Lastly, i divided 144 by 14.4 and got 10 extra hours which got me to my answer of 50 hours because i added the 40 initial hours.

Final answer:

In this case, the man worked 10 hours of overtime.

Explanation:

The question pertains to calculating the regular and overtime pay of a man who earns $9.60 per hour for a standard 40-hour work week and time and a half for any hours worked beyond that. To find how many hours of overtime he worked when he earned $528.00 in a week, we need to use mathematical equations.

First, we calculate the man's regular weekly pay for 40 hours: 40 hours × $9.60/hour = $384.00. Since his total pay is $528.00, the overtime pay is $528.00 - $384.00 = $144.00.

Overtime pay is time and a half, so the overtime rate is $9.60/hour × 1.5 = $14.40/hour. We then divide the total overtime pay by the overtime rate: $144.00 / $14.40/hour = 10 hours of overtime work.

Thus, the man worked 10 hours overtime in addition to his regular 40 hours to make a total of $528.00.

Answer:

The coordinates of Z are (2,7)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

[tex]Y=(\frac{x1+x2}{2} ,\frac{y1+y2}{2})[/tex]

we have

X(-10,9),Y(-4,8)

Let

(x2,y2) ----> the coordinates of Z

substitute the values

[tex](-4,8)=(\frac{-10+x2}{2} ,\frac{9+y2}{2})[/tex]

Solve for x2

[tex]-4=(-10+x2)/2\\-8=-10+x2\\x2=10-8\\x2=2[/tex]

Solve for y2

[tex]8=(9+y2)/2\\16=9+y2\\y2=16-9\\y2=7[/tex]

therefore

The coordinates of Z are (2,7)

Answer:  The required co-ordinates of Z are (2, 7).

Step-by-step explanation:  Given that Y is the midpoint of XZ  and the co-ordinates of X are (-10, 9) and the of Y are (-4, 8).

We are to find the co-ordinates of Z.

Let (a, b) represents the co-ordinates of the point Z.

We know that

the co-ordinates of the midpoint of a line segment with endpoints (x, y) and (z, w) are given by

[tex]\left(\dfrac{x+z}{2},\dfrac{y+w}{2}\right).[/tex]

So, according to the given information, we have

[tex]\left(\dfrac{-10+a}{2},\dfrac{9+b}{2}\right)=(-4,8)\\\\\\\Rightarrow \dfrac{-10+a}{2}=-4\\\\\Rightarrow -10+a=-8\\\\\Rightarrow a=-8+10\\\\\Rightarrow a=2[/tex]

and

[tex]\dfrac{9+b}{2}=8\\\\\Rightarrow 9+b=16\\\\\Rightarrow b=16-9\\\\\Rightarrow b=7.[/tex]

Thus, the required co-ordinates of Z are (2, 7).

The volume of a rectangular prism is found by multiplying its length, width, and height. Given the dimensions as 1 3/4 ft by 1 3/4 ft by 2 1/4 ft, when converted to improper fractions and multiplied together, we find that the volume of the suitcase is 220.5 cubic feet.

The subject of the student's question is focused on the mathematical concept of volume, specifically the volume of a rectangular prism. To find the volume of the suitcase, we need to multiply the length, width, and height of the suitcase. Given that the suitcase's dimensions are 1 3/4 ft by 1 3/4 ft by 2 1/4 ft, we first convert these mixed numbers into improper fractions (7/4 ft by 7/4 ft by 9/4 ft). Then, we multiply them together:

Volume = Length x Width x Height.
Volume = (7/4 ft) x (7/4 ft) x (9/4 ft) = 220.5 ft³.

The volume of the rectangular prism (suitcase) is 220.5 cubic feet.
