Round the following numbers to the nearest 100. The numbers they have 324,558,256
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.

Triangle ABC has a perimeter of 12 units. The vertices of the triangle are A(x,2), B(2,-2), and C(-1,2). Find the value of x.
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
Describe a real world situation that can be represented by the quotient -85\15.
Final answer:
A real world situation that can be represented by the quotient -85/15 is paying off a credit card debt.
Explanation:
A real world situation that can be represented by the quotient -85/15 is the following:
Suppose you owe $85 on your credit card and you make monthly payments of $15. You want to know how many months it will take for you to pay off your debt completely.
To find the answer, you divide the amount you owe ($85) by the monthly payment ($15):
-85/15 = -5.67
This means it will take approximately 5.67 months to pay off your debt.
Solve the formula for the specified variable
A=p+prt solve for r
Answer:
Step-by-step explanation:
The first step is to take p on both sides:
[tex]A - p = p + p*r*t - p[/tex]
On the right hand side, cancel p and -p, since [tex]p-p=0[/tex]. The equation will be:
[tex]A - p = p*r*t[/tex]
Then, divide both sides of the equation by p*t:
[tex]\frac{A-p}{p*t} = \frac{p*r*t}{p*t}[/tex]
On the right hand side, p*t can be cancelled:
[tex]\frac{A-p}{p*t} = r[/tex]
Answer:
r=A-p (the line is the bar so this is a-p over pt)
pt
Step-by-step explanation:
P + Prt = A
P r t=A −P isolate the term which contains r
P rt=A−P

A classroom teacher randomly draws the name of a student. If the teacher has between 20 and 30 students in her class, what is a good estimate of the probability of a specific student's name being drawn?
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.

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).

find the coordinates of Z if Y is the midpoint of XZ , X( -10, 9) , and Y( -4,8)
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).
A man is paid $9.60 per hour for a 40 hour week and he is paid at a time and a half for overtime he worked when his wage for a certain week was $528.00.
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.
