What fraction is located at Point AAA on the number line?

Given expression: 21 + (36 + 0 + 19)

Using identity property of addition: a + 0 = a

21 + (36 + 0 + 19) = 21 + (36 + 19)

Using commutative property of addition: a + b = b + a

21 + (36 + 19) = 21 + (19 + 36)

Using associative property of addition: a + (b + c) = (a + b) + c

21 + (19 + 36) = (21 + 19) + 36

Now, add two numbers inside the bracket.

(21 + 19) + 36 = 40 + 36

Using closure property of addition: a + b = c any number.            

40 + 36 = 76

Hence 21 + (36 + 0 + 19) = 76.

Answer:

[tex]x=-3[/tex]

Step-by-step explanation:

Given the equation

[tex]7=|3x+9|+7[/tex]

1. Use Addition property of equality, add -7 to both sides:

[tex]7-7=|3x+9|+7-7\\ \\0=|3x+9|[/tex]

2. The absolute value of the number is 0 if and only if the number is 0, so

[tex]3x+9=0[/tex]

3. Use Addition property of equality, add -9 to both sides:

[tex]3x+9-9=0-9\\ \\3x=-9[/tex]

4. Use Division property of equality, divide both sides by 3:

[tex]\dfrac{3x}{3}=\dfrac{-9}{3}\\ \\x=-3[/tex]

The solution is x = -3.

To solve the equation 7 = |3x + 9| + 7, let us follow these steps:

First, we simplify absolute value expression:

7 = |3x + 9| + 7

0 = |3x + 9|

The absolute value of a number is zero only when the number itself is zero. So, we set the expression inside the absolute value equal to zero:

3x + 9 = 0

3x = -9

x = -3

The solution to the equation is x = -3.

45 fake dollar.

Step-by-step explanation:

Given: teacher offer 5 fake dollar for each perfect score in Math test.

           One of Student get perfect score on 4 maths test.

          Student already have 25 fake dollor.

Now, solving to find total number of fake dollar teacher offered to student.

As given teacher offer 5 dollar for each perfect score in maths test and student got perfect score on 4 maths test.

Number of fake dollar offer to the student= [tex]Fake\ dollar\ offered\ for\ each\ perfect\ score\ \times\ number\ of\ maths\ test\ with\ perfect\ score[/tex]∴ Number of fake dollar offered to the student=  [tex]5\times 4= 20\ fake\ dollar[/tex]

We know, student already have 25 fake dollar.

Next, finding total number of fake dollar student have.

Total fake dollar student have= [tex]fake\ dollar\ offered\ by\ teacher + fake\ dollar\ student\ already\ have[/tex].

Total fake dollar student have= [tex]20+25= 45\ fake\ dollar[/tex]

Hence, student have total 45 fake dollar to spend in the class store.

Answer:

Parallelogram

Rhombus

Square

Rectangle

Step-by-step explanation:

The quadrilateral ABCD has 2 sets of parallel sides. That is all I know about it.

Now, we have to choose from the options that are the classifications for the quadrilateral.

The quadrilateral ABCD can be a parallelogram with opposite sides are equal and no angles are 90°.

The quadrilateral ABCD can be a rhombus with all sides are equal and no angles are 90°.

The quadrilateral ABCD can be a square with all sides are equal and all angles are 90°.

The quadrilateral ABCD can be a rectangle with opposite sides are equal and all angles are 90°. (Answer)

Answer:

YES

Step-by-step explanation:

Quadrilateral have 4 sides and their sum  of angles is 360 and parallelogram also have 4 sides and sum of angles is 360

Final answer:

The statement that a parallelogram is a quadrilateral is true. A parallelogram is a type of quadrilateral with parallel opposite sides, and its properties are related to the parallelogram law in vector addition.

Explanation:

A parallelogram is indeed a type of quadrilateral with two pairs of parallel sides. In geometry, quadrilaterals are four-sided polygons, and parallelograms are a specific class within that category. Furthermore, in the context of vector addition, the parallelogram law shows how two vectors can combine to form the sides of a parallelogram. This law is closely related to the triangle law of vector addition as both can depict how vectors combine.

An example of the parallelogram's properties in advanced concepts would be where two objects at rest have world-lines that define a rectangle which may become a parallelogram in a different frame of reference. Additionally, the concept of vectors is also relevant when discussing the diagonals of a rhombus, which is a special type of parallelogram with all sides equal in length. Using vectors and their scalar products, it can be shown that the diagonals of a rhombus are always perpendicular to each other.

Answer:

Yes

Step-by-step explanation:

Since the longest side is 6.5 cm, so let it be hypotenuse c.

Verifying by right angle formula

c^2=a^2+b^2

(6.5)^2=(3.9)^2+(5.2)^2

42.25=15.21+27.04

42.25=42.25

Hence the given triangle is a right angles triangle

The simple interest rate was: 1.25%

Step-by-step explanation:

Simple interest is given by:

[tex]A = Prt\\Here\\A => Interest\\P=>Principal\ Amount\\r => Rate\\t => Time\ in\ years[/tex]

Given

Principal amount =$3000

Time = t = 2 years

Interest amount = A = $75

putting the values in the formula

[tex]75 = 3000 * r * 2\\75 = 6000r[/tex]

Dividing both sides by 6000

[tex]\frac{6000r}{6000} = \frac{75}{6000}\\r = 0.0125\\[/tex]

So,

The rate is:

0.0125 * 100 = 1.25%

Hence,

the simple interest rate was: 1.25%

n=1/2×4/3

n=4/6

n=2/3

Answer:

No

Step-by-step explanation:

No, only if the triangle is a right triangle.

Final answer:

No, the centroid of a triangle is not necessarily the center of the circle circumscribing it. The centroid and circumcenter are distinct points that coincide only in equilateral triangles.

Explanation:

No, the centroid of a triangle is not necessarily the center of the circle circumscribing it. The centroid is the point of intersection of the medians of the triangle, which are the lines connecting each vertex to the midpoint of the opposite side. On the other hand, the circumcenter of a triangle is the center of the circle that passes through all three vertices of the triangle.

In some cases, the centroid and circumcenter might coincide, but this happens only when the triangle is equilateral. In all other cases, the centroid and circumcenter are distinct points.

For example, an equilateral triangle has its centroid and circumcenter at the same point. However, in an isosceles triangle, the centroid will lie on the line segment connecting the midpoint of the base to the opposite vertex, while the circumcenter will lie on the perpendicular bisector of the base.

Answer:

[tex]x^{2} +14x=0[/tex]

Step-by-step explanation:

Given:

Given root is

[tex]x=-14,\ 0[/tex]

Now we need to find the quadratic equation for given roots.

Solution:

The given roots are -14 and 0.

So, the sum of the roots.

[tex]\alpha +\beta = -14 + 0[/tex]

[tex]\alpha +\beta = -14[/tex]

Product of the given roots

[tex]\alpha\times \beta = -14\times 0[/tex]

[tex]\alpha\times \beta = 0[/tex]

Therefore, the required quadratic equation is.

[tex]x^{2} -(\alpha +\beta )x+\alpha\times \beta=0[/tex] -------------------(1)

Now we substitute [tex](\alpha +\beta )[/tex] and [tex](\alpha\times \beta)[/tex] in equation 1.

[tex]x^{2} -(-14)x+0=0[/tex]

[tex]x^{2} +14x=0[/tex]

Therefore, the quadratic equation for the given root is. [tex]x^{2} +14x=0[/tex]

Answer: -15

Step-by-step explanation:

[tex]x^{4}[/tex] + 24 = 105

subtract 24 from both sides of the equation .

[tex]x^{4}[/tex] = 105 - 24

[tex]x^{4}[/tex] = 81

find the fourth root of both sides

x = 3

Therefore : substitute x = 3 to find the value of [tex]x^{2} -24[/tex]

[tex]x^{2}[/tex] - 24  =  [tex]3^{2}[/tex] - 24

= 9 - 24

= - 15

So you have a diagram or picture of the triangle?

Anyways...

Answer: 36

Explanation:

3:5:7 is the ratio of the triangle's angles

The sum of all angles = 180 degrees.

3 + 5 + 7 = 15

Lets assume 'a' is the smallest angle with the ratio of 3

b is the second largest with a ratio of 5

And c is the largest angle with the ratio of 7

In other words:

a + b + c = 180

For 15 to get to 180 => 180 ÷ 15 = 12

So 15 × 12 = 180

So for 3 to get to a => 3 × 12 = 36

Thus the smallest angle is 36 degrees

Answer:s

The three angles are 36, 60, and 84 degrees

Smallest angle is 36 degrees

======================================================

Explanation

The ratio 3:5:7 is equivalent to 3x:5x:7x as we can multiply all parts of any ratio by the same number, and still have it be the same ratio.

So we can think of the three angles as 3x, 5x, 7x

Add up those angles. Set them equal to 180 and solve for x.

3x+5x+7x = 180

15x = 180

x = 180/15

x = 12

Use this x value to find the three angle measures

3x = 3*12 = 36

5x = 5*12 = 60

7x = 7*12 = 84

As a check, add up the angles to get: 36+60+84 = 180

So the answer is confirmed.

[tex]x = 4.82[/tex]

Step-by-step explanation:

Given equation is:

6.2 ÷ (2x+1) = 2 1/3 ÷4

Applying the division operation

[tex]\frac{6.2}{2x+1} = 2\frac{1}{3} * \frac{1}{4}\\\frac{6.2}{2x+1} = \frac{7}{3}*\frac{1}{4}\\\frac{6.2}{2x+1} =\frac{7}{12}\\[/tex]

Cross multiplication

[tex]6.2(12) = 7(2x+1)\\14x+7 = 74.4\\14x = 74.4-7\\14x = 67.4[/tex]

Dividing both sides by 14

[tex]\frac{14x}{14} = \frac{67.4}{14}\\x = 4.8142857....[/tex]

Rounding off to nearest hundredth

[tex]x = 4.82[/tex]

Answer:

You can say it as 1 : 24

Step-by-step explanation:

Let us see...

50 head of cattle = 24,500

Divide everything by 50: 1 head of cattle = $490

37 head of cattle = 18,870

Divide the entire equation by 37: 1 head of cattle = $510

The second choice would cost a person $20 more than the first choice, so 50 head of cattle for $24,500 is a better buy.

Answer:

Step-by-step explanation:

Value of x should be  less than (-6).

x = { .......,-9,-8,-7}

For example:

-15*-7 +80 = 105+80 = 185 >170

The solution to the inequality -15x + 80 > 170 is x < -6. We subtract 80 from both sides and then divide by -15, remembering to reverse the inequality sign.

The question provided asks for the solution to the inequality -15x + 80 > 170. To solve the inequality, we can follow these steps:

Therefore, the solution to the inequality is all values of x that are less than -6.

Use the rule a÷b/c=a*c/b

[tex]\frac{2}{3} *\frac{1}{16}+ \frac{11}{12}/ \frac{1}{3}[/tex]

Use the rule a/b*c/d=ac/bd

[tex]\frac{2}{3*16}+ \frac{11}{12}/ \frac{1}{3} \\\\\frac{2}{48} +\frac{11}{12}/ \frac{1}{3} \\\\\frac{1}{24}+\frac{11}{12}/\frac{1}{3}[/tex]

Use the rule a÷b/c=a*c/b

[tex]\frac{1}{24} +\frac{11}{12} *3[/tex]

Use the rule a/b*c=ac/b

[tex]\frac{1}{24}+ \frac{11*3}{12}[/tex]

Simplify three times then you're done.

[tex]\frac{1}{24}+ \frac{33}{12}= \frac{1}{24}+ \frac{11}{4} =\frac{67}{24}[/tex]

Answer: 14

Step-by-step explanation: If you add 7 to 8 you get 15 so if he spent half of his allowance you multiply 7 by 2 so your answer is 14.

James's weekly allowance is calculated by setting up an equation based on the information given. After spending half of his allowance on clothes and earning an additional $8, the equation 0.5A + $8 = $15 is solved to reveal that James's weekly allowance is $14.

The student's question involves solving for James's weekly allowance, given that he spent half of it on clothes and earned an additional $8 by cleaning the oven, which resulted in him having a total of $15 at the end. To solve the problem, we need to set up an equation where 'A' represents James's weekly allowance.

James spent half of his allowance on clothes, which means he has half of it left. So, we can represent this as 0.5A. Then he adds $8 from cleaning the oven: 0.5A + $8 = $15. We isolate 'A' by subtracting $8 from both sides of the equation: 0.5A = $15 - $8, which simplifies to 0.5A = $7. To find the full value of his allowance (A), we divide by 0.5: A = $7 / 0.5, so A = $14.

Thus, James's weekly allowance is $14.

Answer:

Explanation:

The variability of a sample may be described by using some common statistics like the variance and the standard deviation.

The variance and the standard deviation measure the difference between the values of the data  and the mean. The variance is the average square of those differences or deviations. The standard deviation is the square root of the variance.

Thus, both variance and deviations, being an average of the differences of the data from the mean contain the number of data in the denominator of the equation.

That lets you know to conclude that the larger the number of data (the larger the sample) the smaller the variance and the standard deviation, this is the lower the variability of the data.

Hence, Network C, which has the greatest number of voters sampled (1,800) is likely to have the least variability.
