Decending order- From greatest to least
To order them start with the dight with the highest number in the place that isn't equal. In this case it the 4 in the hundredths place so are top 3 numbers are 0.741, 0.7412, and 0.744. As this point you continue to look at the greatest number when the dights aren't equal so the top three would be ordered 0.744,0.7412
0.744,0.7412, and 0.741. As for the bottom 2 numbers you do the same thing with the top three numbers so the rest of the list is 0.70411 and 0.7041
WRITING IN MATH Explain why a triangle cannot have an obtuse, acute, and a right exterior angle.
A triangle cannot be both right-angled and obtuse-angled. Because a right-angled triangle has only one right angle, its other two are acute.
Triangle property defined as:The sum of all triangle angles (of all types) equals 180°. The total of the lengths of a triangle's two sides is higher than the length of something like the third side. Similarly, the length of something like the third side is less than the differences between two sides of a triangle.
What are the various types of triangles?Triangles are categorized in two ways: thus according to internal angles and based on the side length. There are three sorts of triangles based on internal angles: acute, right, and obtuse-angled triangles. Triangles are categorized into three types based on the length of its sides: Scalene, Isosceles, and Equilateral triangles.

A. 0.11
B. 0.17
C. 0.33
D. 0.39
E. 0.67
The probability that the chosen marble will be red is, 0.27.
Probability:
Probability is calculated by using the formula,
P(A) = n(A)/n(S)
Where,
P(A) is the probability of an event “A”
n(A) is the number of favorable outcomes.
n(S) is the total number of events in the sample space.
Given,
A box contains 7 blue marbles, 6 red marbles, 2 white marbles, and 3 black marbles.
Here we need to find If one marble is chosen at random, then what is the probability that it will be red.
According to the formula,
number of favorable outcomes = 6
total number of events in the sample space = 7 + 6 + 2 + 3 = 22.
Then the probability of getting red marbles is,
=> P(A) = 6/22.
It can be simplified as,
=> P(A) = 3/11
=> P(A) = 0.27
Therefore, the probability of getting red marble is 0.27.

Write an equation of the line through each pair of points in slope-intercept form.
(2,4) and (-4,-11)
The equation of line is:
y = (5/2) x - 11
Given,
Points (x₁, y₁) = (2, 4) and (x₂, y₂) = (-4, -11)
We can find the slope using the equation for slope
m = (y₂ - y₁) / (x₂ - x₁)
= (-11 -4) / (-4 -2)
= -15 / - 6
= 5/2
We know the slope and a point, so we can use point slope form to make an equation
y-y₁ = m(x-x₁)
y - (-4) = 5/2 (x-2)
Distribute
y+4 = 5/2x – 5/2 x 2
y+4 = 5/2x - 5
Add -4 to each side
y +4 -4 = 5/2x – 5 - 4
y = 5/2x - 11

A triangle is dilated with the center of dilation at point U. Point E is a vertex of the triangle and point E ’ is the corresponding vertex of the image. If UE = 2 centimeters and UE ’ = 10 centimeters, the scale factor is 5 cm
Scale Factor Definition
A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. If the scale factor is a whole number, the copy will be larger. If the scale factor is a fraction, the copy will be smaller.
By definition, a Dilation is a transformation in which the image has the same shape as the pre-image but size changes.
The center of dilation is a fixed point in the plane, and the scale factor is the ratio of the corresponding sides of the image to the pre-image.
Scale Factor In Geometry
Scale is used in geometry to make accurate reproductions of figures; they are different sizes, but same proportions. Figures are similar but to scale.
Based on the information provided in the exercise, you know that:
UE = 2 centimeters

Define Scale Factor
The ratio between comparable measurements of an object and a representation of that object is known as a scale factor in mathematics. The copy will be larger if the scaling factor is a whole number. A fractional scaling factor means that the duplicate will be smaller.
A dilation is, by definition, a transformation in which the size of the image changes but the shape remains the same as the pre-image.
The scale factor is the ratio of the corresponding sides of the image to the pre-image, and the center of dilatation is a fixed point in the plane.

The density of the rock is 25g.

If the water rose 7 ml−2ml=5ml then the stone had a volume of 5 ml or 5cc
With a mass of 25 g it must have a density of = 25 g

m = slopeb = y-interceptTherefore, using (-2, 0)(3, -4) let's find the slope
m = -4 - 0 / 3 - (-2)
m = - 4 / 3 + 2
m = - 4 / 5
Hence, the y = mx + b can be defined as follows:

Answer:
x= 82⁰The measure of angle RST = 88⁰x= 12⁰x = 10⁰x = 51⁰x = 128⁰x= 10⁰x = 5⁰The measure of angle JGH = 57⁰ The measure of angle GEF = 33⁰Step-by-step explanation:
To answer question one you first make a equation for the angle we know that x+63=145. Then do the inverse of addition which would be subtraction so x+ 63- 63 = 145 -63which is x=82⁰Since angle RSU and UST equal to angle RST you would combine both values 41 and 47 together (41+47) and you will get the measure of RST which is 88⁰To answer question 3, 4, 5 and 6 (question 3 is the demonstration) Create an equation with the given numbers: We know that m< JKL is 131 and that is the combination of m< JKN (48⁰) and m< NKL (7x -1)⁰ that is 7x-1 + 48 = 131Combine like terms (if any): the only like terms in the equation are -1 and 48 so the new equation is 7x+47=131 Do the inverse operations: For instance the first operations you would do is subtracting 47 on both sides (the point is to islolate x) 7x + 47- 47 = 131 - 47 now the new equation is 7x=84. Divide 7 on both sides the final answer is x=124. To answer questions 4,5 and 6 you would apply the same steps for question 3. Your final answer for question 4 is x = 10.
5. The only difference for question 5 is that the measure of the angles combine is not explicitly given and it is a right angle (from the square in the corner) which means the total is 90⁰ and the final answer is for question 5 is 51⁰
6. For question 6 you need to know that the total is 180⁰. The final answer is 128⁰
7. Steps to solve questions 7,8,9 and 10 (question 7 is the demonstration) :
Combine like terms: The terms 6x and 5x (in 6x+5x+2=112) are like terms so you add them together. the new equation is 11x +2 = 112 Do the inverse operations: Subtract 2 from both sides 11x+2-2= 112-2 which is 11x = 110. Divide 11 from both sides the final answer is x = 108. Apply the same step for question 7: the final answer is x = 5
9. Apply the same steps for step 7 however you substitute x in m < JGH which is 4x + 1 which is 57⁰
10. Apply the same steps for step 7 however you substitute x in m < GEF (11x) which is 33⁰

Write an equation of each line.slope =-1 ; through (-3,5)
The equation of the line in point-slope form, with slope equal to -1 and passing through the point located at (-3 , 5), is (y - 5) = -1(x + 3).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Using the point slope form, plug in the values to set up the equation.
(y - y1) = m(x - x1)
where m = -1 and (x1 , y1) = (-3 , 5)
(y - 5) = -1(x - -3)
(y - 5) = -1(x + 3)
In slope-intercept form, the equation of the line is:
(y - 5) = -1(x + 3)
y - 5 = -x -3
y = -x + 2
In standard form, the equation of the line is:
y = -x + 2
x + y = 2

What is fraction?Fractions represent portions of a whole or set of objects. A fraction is divided into two pieces. The numerator is the number at the top of the line. It indicates how many equal chunks of the total or collection are taken. The denominator is the number below the line. It indicates the total number of equal pieces into which the whole is divided or the total number of the same objects in a collection.
If 72 spoons is 3.89
Then 1 spoons is 3.89/72
