Shane said that he could write related multipication and addition sentences for 6+4+3. does shane's statement make sense? explain
Answer:
Shane's statement is not correct.
Step-by-step explanation:
Shane said that he could write related multiplication and addition sentences for 6+4+3.
No, Shane's sentence does not make any sense as if we add the digits we get = [tex]6+4+3=13[/tex]
But when we multiply the digits we get = [tex]6*4*3=72[/tex]
So, how can he relate these two different things.
Hence, i guess no is the answer.

To multiply the given radicals, first simplify the radicals to get like terms, then multiply coefficients and like radicals separately. The result of multiplying 4√3 × 10√12 × √6 × √2 is 480√3.
The task is to multiply the following radical expressions: 4√3 × 10√12 × √6 × √2.
First, let's simplify the radicals where possible. We know that √12 can be broken down into √4×√3, because 4 is a perfect square and 4×3=12. Thus, √12 simplifies to 2√3. Now, our expression looks like: 4√3 × 10×2√3 × √6 × √2.
Next, we multiply the coefficients (numbers outside the radicals) and the like radicals separately:
Coeficients: 4 × 10 × 2 = 80Radicals: √3 × √3 × √6 × √2 Multiplying the radicals, we get (√3)^2 × √6 × √2. Since the square of a square root equals the number itself, (√3)^2 = 3. Therefore, we have 3 × √6 × √2.Simplifying further, we can pair √6 and √2 to get √12, which we already simplified earlier into 2√3. Thus, 3 × 2√3 = 6√3.
Finally, we multiply the coefficient we got from our first step (80) by the simplified radical (6√3) to get the final answer: 480√3.
Which two points are on the graph of y = x - 3?
(1, -2), (-1, 3)
(1, 2), (0, 3)
(0, -3), (4, 1)
(3, 0), (0, 3)
Answer:
(0, -3), (4, 1)
Step-by-step explanation:
Given: Graph of y = x - 3
We need to find which points are on the graph of y = x - 3 .
A point [tex]\left ( x_1,y_1 \right )[/tex] is said to lie on the graph of y = f(x) if it satisfies the equation. i.e if [tex]y_1=f(x_1)[/tex]
Here, we will first check if points (0, - 3), (4, 1) lie on the graph:
For (0, - 3):
L.H.S = y = - 3
R.H.S = x - 3 = 0 - 3 = - 3
L.H.S = R.H.S
So, (0, - 3) satisfies the given equation.
For (4, 1):
L.H.S = y = 1
R.H.S = x - 3 = 4 - 3 = 1
L.H.S = R.H.S
So, (4, 1) satisfies the given equation.
Therefore, two points (0, - 3), (4, 1) satisfy the equation y = x - 3
△ABC is mapped to △A′B′C′ using each of the given rules.
Which rules would result in △ABC being congruent to or not congruent to △A′B′C′ ?
Drag and drop each rule into the boxes to classify it as Congruent or Not Congruent.
Answer:
Congruent: (x, y)→(x+3, y-4); (x, y)→(-x, -y)
Not Congruent: (x, y)→(3x, 3y); (x, y)→(0.4x, 0.4y); (x, y)→(x/3, y/3)
Step-by-step explanation:
Transformations that result in congruent figures are translations, rotations and reflections. Translations that result in figures that are not congruent are dilations.
The first transformation, (x, y)→(x+3, y-4) is a translation 3 units to the right and 4 units down. This will result in congruent figures, since it only slides the figure.
The second transformation, (x, y)→(3x, 3y) is a dilation by a factor of 3. A dilation is a stretch or a shrink; a dilation factor of 3 will stretch the figure. Since it is stretched, it is not the same size and therefore not congruent.
The third transformation, (x, y)→(0.4x, 0.4y) is a dilation by a factor of 0.4. This dilation will shrink the figure. Since it is shrunk, it is not the same size and therefore not congruent.
The fourth transformation, (x, y)→(x/3, y/3) is a dilation by a factor of 1/3. This dilation will shrink the figure. Since it is shrunk, it is not the same size and therefore not congruent.
The fifth transformation, (x, y)→(-x, -y) is a reflection. This does not change the size of the figure, just the placement and orientation of it. Since the size is not changed, the figure is congruent.
Answer:- Congruent = (x, y)→(x+3, y-4)
(x, y)→(-x, -y)
Not Congruent= (x, y)→(3x, 3y)
(x, y)→(0.4x, 0.4y)
(x, y)→(x/3, y/3)
Explanation:
1.The transformation (x, y)→(x+3, y-4) is a translation ,where the x coordinates of points of ΔABC translate 3 units toward right and the y coordinate translate 4 units downwards .Translation is rigid transformation which does not change the size of the figure, it just translate every point of a figure by a fixed distance to create its image. Thus this would result in △ABC being congruent to △A′B′C′.
2.The transformation (x, y)→(3x, 3y) is a dilation by a factor of 3.Since after dilation the size of image becomes different, thus this would result in △ABC being not congruent to △A′B′C′.
3.The transformation (x, y)→(0.4x, 0.4y) is a dilation by a factor of 0.4.Since after dilation the size of image becomes different, thus this would result in △ABC being not congruent to △A′B′C′.
4.The transformation (x, y)→(x/3, y/3) is a dilation by a factor of 1/3. Since after dilation the size of image becomes different, thus this would result in △ABC being not congruent to △A′B′C′.
5.The transformation (x, y)→(-x, -y) is a reflection. Reflection is a rigid transformation which does not change the size of the figure, it create exactly same sized image of the original figure, Thus this would result in △ABC being congruent to △A′B′C′.
For what value of x must ABCD be a parallelogram?
For ABCD to be a parallelogram, the value of x must be?
Answer: The value of x must be 7 units.
Step-by-step explanation:
Since we have given that
ABCD is a parallelogram.
Suppose that AC and BD intersect at o.
So, AO = OC.
And we have given that
AO = 5x
OC = 6x-7
According to question,
[tex]5x=6x-7\\\\5x-6x=-7\\\\-x=-7\\\\x=7[/tex]
Hence, the value of x must be 7 units.
In geometry, for ABCD to be a parallelogram, certain conditions must hold true, such as equal opposite sides or equal opposite angles. The specific value of x would be determined based on the specific properties or relations outlined in your question.
Explanation:In Mathematics, specifically in geometry, a quadrilateral ABCD is a parallelogram if opposite sides are equal in length (i.e., AB = DC and BC = AD), or if opposite angles are equal (i.e., ∠A = ∠C and ∠B = ∠D), or if one pair of opposite sides are both parallel and equal (i.e., AB || DC and AB = DC).
The value of x would be determined based on the specific properties or relations given in your problem. You would have to set up the equations based on these properties or relations, and solve for x.

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees who have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees who have been with the company for at least three years, but fewer than six years can expect an increase of $1.00. Employees who have been with the company for at six years, but fewer than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but fewer than twelve years receive an increase of $2.00.

Magnesium combines with oxygen to form magnesium oxide. A 100-gram sample of magnesium combines with 65.8 grams of oxygen. A 10-gram sample of magnesium combines with 6.58 grams of oxygen. Which point of Dalton’s atomic theory is supported by these findings? All atoms of the same element have the same mass, and atoms of different elements have different masses. All elements are composed of atoms. In a particular compound, atoms of different elements always combine in the same way.
Answer: The correct answer is in a particular compound, atoms of different elements always combine in the same way.
Explanation:
Postulates of Dalton's theory were:
Matter is made up of indivisible particle which are known as atoms.The properties of all the atoms of an element are same including its mass. It can also be said that the mass of all the atoms of an element is same while the mass of all atoms of different elements are different.Atoms of different elements combine in fixed ratio by their mass to form compounds. Atoms are neither created nor destroyed. It can also be said that in a chemical reaction, atoms can neither be created nor be destroyed.We are given a reaction of magnesium with oxygen to produce magnesium oxide.
Case 1:Mass of magnesium = 100 grams
Mass of oxygen = 65.8 grams
Mass ratio of magnesium and oxygen = [tex]100:65.8=1.51:1[/tex]
Case 2:Mass of magnesium = 10 grams
Mass of oxygen = 6.58 grams
Mass ratio of magnesium and oxygen = [tex]10:6.58=1.51:1[/tex]
From both the cases, it is visible that magnesium and oxygen are combining in a fixed ratio by their masses to form magnesium oxide.
Hence, the correct answer is in a particular compound, atoms of different elements always combine in the same way.
Answer:
In a particular compound, atoms of different elements always combine in the same way.
Step-by-step explanation:
Dalton's atomic theory postulate:
1.All matter consist of indivisible particles called atoms.
2.Atoms of same element are identical in shape and mass. Atoms of different element are different in shape and mass.
3.Atoms cannot be created or destroyed.
4.Atoms of different elements may combine with each other in a fixed , simple, whole number ratios to form compounds.
5.Atoms is the smallest unit of matter that can take part in a chemical reaction.
Mass of magnesium in a sample=100 g
Mass of oxygen in a sample=65.8 g
Ratio of Mg to O=100:65.8=1.52:1
Mass of magnesium in other sample=10 g
Mass of oxygen in other sample=6.58 g
Ratio of Mg to O=10:6.58=1.52:1
Hence, the ratio of Magnesium to oxygen in each sample=1.52:1
Therefore, the point supported by given information is

One of two complementary angles is 8 degrees less than the other.
Which of the following systems of equations represents the word problem?
x + y = 90 and x - y = 8
x + y = 90 and 90 - x = 8
x + y = 90 and y = 8x
Answer:
( x+y = 90 ) and ( x - y = 8 )
Step-by-step explanation:
In this question we will form the equation as per statements given.
"One of two complementary angle is 8 degrees less than the other."
Let the two angles are 'x' and 'y'
By the statement ( y = x - 8 )
y - x = (-8)
or x - y = 8 -----------(1)
"Both the angles are complementary."
x + y = 90° -----------(2)
Therefore, system of equations will be
( x+y = 90 ) and ( x - y = 8 )
