The quadrilateral ABCD indicates that it is a rhombus.

A quadrilateral with four equal-length sides is known as a rhombus in plane Euclidean geometry (plural rhombi or rhombuses). Another name for this object is an equilateral quadrilateral because all of its sides are equal in length.

The rhombus is frequently referred to as a "diamond" after the diamonds suit in playing cards, which resembles the projection of an octahedral diamond, or as a "lozenge," though the former term is occasionally used to refer specifically to a rhombus with a 60° angle which some authors refer to as a calisson after the French sweet , and the latter term is occasionally used to refer specifically

Brianna will use 0.17 liters of the liquid

We know that an equation in which two ratios are set equal to each other is called as proportion.

Here, Brianna has a container which has 0.85 L of liquid in it.

Brianna needs to use 0.2 of this liquid.

Assume that 0.85 L represents the 100% of the liquid.

Then 0.2 represents 0.2 × 100 = 20% of the liquid .

Let Brianna will use x liters of liquid.

Consider a proportion.

It is proved that a triangle is divided into four congruent triangles by the line segments connecting the middle points of its sides.

A triangle in geometry is a three-sided polygon with three edges and three vertices.

The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.

This characteristic is known as the triangle's angle sum property.

If ABC is a triangle, it is written as ABC, where A, B, and C represent the triangle's vertices.

In Euclidean geometry, a triangle is a two-dimensional shape that is represented by three non-collinear points in a single plane.

A closed, two-dimensional shape is a triangle. It is a polygon with three sides. Straight lines make up all of the sides.

The vertex is the intersection of two straight lines. The triangle therefore has three vertices.

Hence, It is proved that a triangle is divided into four congruent triangles by the line segments connecting the middle points of its sides.

The area of circle with circumference 5πm is 6.25π square meters.

What is circumference and area of a circle?

The measurement of the circle's perimeter, also known as the circle's boundary, is called its circumference.

Circumference of circle(C)= 2πr

The area of a circle is the space encircled or encompassed by its circumference. It has a square unit of measurement.

Area of circle(A)= πr^2

We are given the circumference of circle(C)= 5π

This implies that 2πr= 5π because C= 2πr

On solving the equation,

2πr= 5π

r=5/2

=2.5

Now, area of circle(A)= πr^2

So, A= π (2.5)^2

A= 6.25π square meters

Hence, The area of circle with circumference 5πm is 6.25π square meters.

yes. 904 is divisible  by 8  and quotient is 113.

Divisibility Rule of 8

If the last three digits of a number are divisible by 8, then the number is completely divisible by 8. Example: Take number 24344. Consider the last two digits i.e. 344. As 344 is divisible by 8, the original number 24344 is also divisible by 8.

What is an arithmetic progression?

"Arithmetic Progression is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value."

Let, there are 'n' terms less than 904 divisible by 3.

Now, the first term divisible by 3 is(a) = 3.

The second term divisible by 3 is = 6.

Therefore, the common difference between terms divisible by 3 is(d)

Answer:

Equation:

Value of x:

[tex]x = 20[/tex]

Step-by-step explanation:

In the figure, we are given 2 angles, 150° and (7x+10)°.

These 2 angles are vertical angles because they are directly opposite of each other and formed by intersecting lines.

Vertical angles are congruent, which means the same.

Thus, to make an equation to solve for x, we need to set the angles equal to each other.

Equation: [tex]7x + 10 = 150[/tex]

Solving for x:

[tex]7x + 10 = 150[/tex]

⇒ [tex]7x = 140[/tex] . . . . . . . . . subtract 10 from both sides of the equation

Step-by-step explanation:

the equation for g(x)= 32x-7

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

EXPLANATION

We want to find the equation for g(x).

First, the function is stretched vertically by a factor of 4. This means that the function changes as follows:

f(x)→4f(x)

Therefore, the function becomes:

4(8x)

=32x

Then, it is translated 7 units down. This means that the function changes as follows:

f(x)→f(x)-7

Therefore, the equation for g(x) is:

g(x)=32x-7

Hence, the equation for g(x)= 32x-7.

The solution of (x^2 +  6x - 16) is ( x+8 )( x−2 ).

Lets solve the equation (x^2 +  6x - 16) in order to find its solution:

The equation is ( x^2 + 6x − 16 )

Now factorizing it

= ( x^2 + 8x − 2x − 16)

Taking x common from the first two terms and -2 common from the last two terms:

= [x (x+8) −2 (x+8) ]

Now,

= [ (x+8) (x−2) ]

Therefore, it is shown that the solution of the equation "(x^2 +  6x - 16)" is (x+8)(x−2) which is obtained through factorization.

Step-by-step explanation:

See attached worksheet.  The derivation of the answer, x - $69 = $31 (then x = $100) is shown.  Convert the written question into an equation:  If x is the amount given the cashier, then once $69 is subracted, Lemon receives $31:

   x - $69 = $31

This can be rearranged to:  x - $31 = $69, the second answer option.  Other options have errors, noted by the red circles.  There are no reasons that inequalities are involved, and seemingly random values of $61 and $30 have no relationship to the problem.

Answer:

B)  Let x = amount paid to cashier

         x - $31 = $69

         x = $100

Step-by-step explanation:

We want to determine the amount Lemon paid the cashier.  Therefore, the unknown variable is:

If Lemon received $31 in change, then the amount he paid the cashier less the change is equal to the cost of the walnuts:

To solve the equation, add $31 to both sides:

On a negatively skewed curve The mean is lower than the median which is lower than the mode. The correct answer is E.

In statistics, a distribution is said to be negatively skewed if more values are concentrated on the right side (tail) of the distribution graph and the left tail is longer.

Positive skew is characterized by a longer or fatter tail on the right side of the distribution, and negative skew is characterized by a longer or fatter tail on the left. These two skews represent the direction or weight of the distribution.

The central tendency of a distribution is defined as its mean, median, and mode. The fact that the mean, median, and mode of the typically skewed data are all equal demonstrates the equality of wealth and income distribution as well as the significance of governmental policies and economic progress.

The distributions have a wide gap because the negative side is so heavily weighted. For instance, the data shows that the distribution of income is unequal and negatively skewed, and the central tendency is as follows:

Mode > Median > Mean.

To find the equation of an asymptote from a graph, look for the line that the graph approaches but never touches. Then calculate the slope of the line and the y-intercept. This will give you the equation of the asymptote.

To find the equation of an asymptote from a graph, look for the line that the graph approaches but never touches. Asymptotes usually run parallel to the x-axis or the y-axis, so look for a straight line that is horizontal or vertical.

Once you have identified the line, calculate the slope of the line and the y-intercept. The slope of the line is the ratio of the change in the y-values to the change in the x-values.  

Once you have found the slope and the y-intercept, you can use the slope-intercept form of a line to find the equation of the asymptote: y = mx + b, where m is the slope and b is the y-intercept. This will give you the equation of the asymptote.

Step-by-step explanation:

The length of side m is, 5.08 inches.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In ΔMNO,

⇒ o = 8 inches, m ∠M = 28° and m ∠O = 48°.

Now, Let the length of side m = x

So, By sine rule, we get;

⇒ sin M / m = Sin O / o

Substitute all the values, we get;

⇒ sin28°/  x = sin 48° / 8

⇒ 0.47 / x  = 0.74 / 8

⇒ x = 0.47 × 8 / 0.74
