Which answer is a reasonable estimate to the following problem? 194 x 476
To estimate the product of 194 x 476, we round each number to the nearest hundred and multiply. After rounding, the multiplication is 200 x 500, which equals 100,000. This is a reasonable estimate for the multiplication problem.
Explanation:The subject of this question is Mathematics, and the grade level appears to be Middle School. The student is asking for a reasonable estimate of the product of 194 and 476.
To estimate the product of 194 x 476, we should round each number to a convenient figure before multiplying. Both numbers round to the nearest hundred, with 194 rounding down to 200 and 476 rounding up to 500.
The estimate calculation would therefore be:
Round 194 down to 200 (because it is closer to 200 than to 300).Round 476 up to 500 (because it is closer to 500 than to 400).Multiply the rounded numbers: 200 x 500.When we multiply these rounded figures, we get:
200 x 500 = 100,000
This is a reasonable estimate for the product of 194 x 476.

9.1÷3576 rounded to the nearest whole number
Answer:
Answer is 0
Step-by-step explanation:
[tex]\frac{9.1}{3576}=0.0025447427[/tex]
Whole numbers are the set of numbers represented by {0,1,2,3.......}, So basically counting numbers with a 0. Whole numbers does not contain fractions or negative numbers.
Rounding off is a way of simplifying a number so that it is close to the value of the original number. 0.0025447427 lies in between the whole number 0 and 1. But is is a very small value and is close to 0 than 1. So the closet whole number is 0.

Solve y−3x=13 for y.
Answer:
y=13+3x
Step-by-step explanation:
The equation y - 3x = 13 can be solved for y as y = 13 + 3x after adding 3x both sides.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The linear equation is:
y - 3x = 13
It is required to solve for x
The expression can be defined as the combination of constants and variables with mathematical operators.
Make the subject as y:
Add 3x on both sides:
y - 3x + 3x = 13 + 3x
y = 13 + 3x
Thus, the equation y - 3x = 13 can be solved for y as y = 13 + 3x after adding 3x both sides.

For each order pair ,determine whether is it a solution to 7x+4y=-23
Simplifying
7x + -4y = 23
Solving
7x + -4y = 23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
7x + -4y + 4y = 23 + 4y
Combine like terms: -4y + 4y = 0
7x + 0 = 23 + 4y
7x = 23 + 4y
Divide each side by '7'.
x = 3.285714286 + 0.5714285714y
Simplifying
x = 3.285714286 + 0.5714285714y
An order pair is a solution to the given equation 7x+4y=-23 if substituting the values of the order pair into the equation makes the equation correct. Using this method it can be determined for instance that (1,-6) is not a solution whereas (-1,-5) is a solution to the equation.
Explanation:To determine whether an order pair is a solution to the given equation 7x+4y=-23, you'll need to substitute the values of x and y from the order pair into the equation and see if both sides of the equation balance out.
For instance, if your order pair is (1, -6), you would substitute x=1 and y=-6 into the equation. The equation would then become: 7(1) + 4(-6) = -23. Simplifying this, you get 7 - 24 = -23, which is incorrect.
If you were to take the order pair (-1,-5), the equation 7(-1) + 4(-5) = -23 simplifies to -7 - 20 = -23 , which is indeed correct. Therefore, the order pair (-1,-5) is a solution to the given equation.

The coordinates of the vertices for the figure HIJK are H(0, 5), I(3, 3), J(4, –1), and K(1, 1).
To determine if it is a parallelogram, use the converse of the parallelogram diagonal theorem. This states that if the diagonals , then the quadrilateral is a parallelogram.
The midpoint of HJ is and the midpoint of IK is (2, 2).
Therefore, HIJK is a parallelogram because the diagonals , which means they bisect each other.
Answer: The quadrilateral HIJK is a parallelogram.
Explanation:
It is given that the coordinates of the vertices for the figure HIJK are H(0, 5), I(3, 3), J(4, –1), and K(1, 1).
The parallelogram diagonal theorem states that the quadrilateral is a parallelogram if both diagonal bisects each other.
If HIJK is a quadrilateral, then HJ and IK are the diagonals of HIJK.
First we find the midpoint of HJ.
[tex]\text{Midpoint of HJ}=(\frac{0+4}{2}, \frac{5-1}{2})[/tex]
[tex]\text{Midpoint of HJ}=(2,2)[/tex]
Now, find the midpoint of IK.
[tex]\text{Midpoint of IK}=(\frac{3+1}{2}, \frac{3+1}{2})[/tex]
[tex]\text{Midpoint of IK}=(2,2)[/tex]
The midpoint of both diagonal are same. It means the diagonals of HIJK bisects each other.
By parallelogram diagonal theorem, we can say that the quadrilateral HIJK is a parallelogram.

In the lunch room at your school, 5 people can sit at one table. If you put two tables together, 8 people can sit. If you put three tables together, 11 people can sit. How many people can sit if you put 20 tables together?
Based on the pattern, with each added table, 3 more people can sit. Now, let's see, how many people can sit when we put 20 tables together.
1. First, count the number of 'extra' tables after the first one. With 20 tables in total, we subtract 1 for the initial table to obtain 19 extra tables.
2. We know that for each extra table, 3 more people can sit. So, we then multiply the 19 extra tables by 3, which results in 57.
3. Recall that with the first table, 5 people could sit.
4. To get the total number of people that can sit, we then add the calculated extra seats, which is 57, to the initial 5 seats. So, 57 + 5 equals 62.
So, when you put 20 tables together, 62 people can sit according to the pattern we have noticed.

The most general proccedure for this type of problems is the following:
For a quadratic function of the following form [tex]f(x)=x^2+bx+c[/tex]; where b and c are real numbers.
1) Identify the value that accompanies the x, that is, the value "b"
2) Divide the value of b by 2 and then square it: [tex](\frac{b}{2})^2[/tex]
3) Add and subtract in the function the value of [tex](\frac{b}{2})^2[/tex]
4) Write the complete function of the form [tex]f(x) = (x+\frac{b}{2})^2-(\frac{b}{2} )^2+c[/tex]
For the function presented [tex]f(x)=x^2 +12x+6[/tex] the result is as follows:
1) The value of b is 12
2) [tex](\frac{12}{2} )^2=36[/tex]
3) [tex]f(x)=(x^2+12x+36)-36+6[/tex]
4)[tex]f(x)=(x+6)^2-36+6[/tex]
