4th number after decimal is 6, which is greater than 5. the value of 3rd number after dp goes up by 1
therefore 0.566

Order the sides of DEF in order from least to greatest
The sides of DEF in order from least to greatest will be x + 6, (5x - 8) and (9x + 2).
How to calculate the angle?The total angles that can be found in a triangle is 180°.
Therefore, the angles will be illustrated thus:
x + 6 + (5x - 8) + (9x + 2) = 180°
x + 6 + 5x - 8 + 9x + 2 = 180°
15x = 180°
Divide
x = 180° / 15.
x = 12°
Therefore,
x + 6 = 12 + 6 = 18°
(5x - 8) = 5(12) + 8
= 60 + 8
= 68°
(9x + 2) = 9(12) + 2
= 108 + 2
= 110°

In triangle RST, m∠R > m∠S + m∠T. Which must be true of triangle RST? Check all that apply.
m∠R > 90°
m∠S + m∠T < 90°
m∠S = m∠T
m∠R > m∠T
m∠R > m∠S
m∠S > m∠T
The option that must be true of triangle RST include:
m∠R > 90°
m∠S + m∠T < 90°
m∠R > m∠T
m∠R > m∠S
How to illustrate the triangle?From the information illustrated in the triangle, R > S + T. It should be noted that based on the information, one angle is more than the sum of the other two angles.
Sum of angles in a triangle = 180°
If an angle is 90°, the sum of the other two angles will be 90°.
Therefore, if R = 120°, it so greater than 90°. The correct options are illustrated above.

The y-intercept is y = 10, and that is the initial height of the flower in inches.
And the rate of change between n = 1 and n = 5 is:
R = 0.21
What is the y-intercept?For any function y = f(x), the y-intercept is the value that y takes when we evaluate in x = 0.
In this case, we have the exponential function:
g(n) = 10*(1.02)^n
Evaluating in n = 0 we get:
g(0) = 10*(1.02)^0 = 10*1 = 10
The y-intercept is y = 10, and it means that the initial height of the flower is 10 inches.
Now we want to get the average rate of change on the interval [1, 5].
Remember that for a function f(x) the average rate of change on an interval [a, b] is:
R= [ f(b) - f(a)]/(b - a)
In this case we will have:
R = [ g(5) - g(1)]/(5 - 1) = [g(5) - g(1)]/4
Where:
g(5) = 10*(1.02)^5 =11.041
g(1) = 10*(1.02) = 10.200
Replacing that:
R = [11.041 - 10.200]/4 = 0.21
This means that the plant increases about 0.21 inches per day on these 4 days.

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Let b represent the number of books.
So, the equation will be
5b - 7 = 58
Now, add 7 to both sides of the equation
5b = 65.
b = 13.
Thus, she bought 13 books at 5 dollars a piece.
After she gets a 7 dollar discount off of 65 dollars, so she paid a total of 58 dollars after the discount.

HELP
Answer: 700x+1700
This represents the total amount spent over the x weeks that have gone by.
===========================================
Explanation:
x = number of weeks
700x = amount spent over those x weeks ($700 per week)
700x+1700 = total amount spent when adding on the $1700 tv.
------
An example:
Let's say x = 10 weeks have elapsed. He spends $700 a week, so 700x = 700*10 = 7000 dollars have been spent so far if we ignore the tv. Then add on the $1700 tv cost to get 7000+1700 = 8700 dollars total spent.
Then note how 700x+1700 = 700*10+1700 = 8700 matches what we got earlier.
I recommend trying out other values of x to get a better idea of what's going on.

The solution to the given system of linear equations is x = -2 and y = -8. That is, (-2, -8).
Solving system of linear equationsFrom the question, we are to determine the solution to the given system of linear equations.
The given system of linear equations is
y = 5x + 2 ---------- (1)
4x - y = 0 ---------- (2)
Substitute equation (1) into equation (2)
4x - y = 0
4x - (5x + 2) = 0
4x - 5x -2 = 0
-x -2 = 0
-2 = x
x = -2
Substitute the value of x into equation (1)
y = 5x+ 2
y = 5(-2) + 2
y = -10 + 2
y = -8

The statement 'If an integer is negative, its absolute value is also its additive inverse.' is True.
In this question, we have been given a statement 'If an integer is negative, its absolute value is also its additive inverse.'
We know that for any non zero real number 'm', the additive inverse is '-m'
as m + (-m) = 0
We know that the absolute value of any non-zero real number is always positive.
Consider a negative integer -p.
The absolute value of -p is |-p| = p

10-6x + 9x = x+2 solving variables
The required value of the variable x is - 4
What are variables ?A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are utilised. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants.
The given equation is :
10-6x + 9x = x+2
On solving this equation we get :
10 + 3x = x + 2
Subtract - 3x on both sides and we will get
10 = - 2 x + 2
Subtract 2 on both sides
we get
8 = -2x
On dividing both sides of the equation by 2 we get
x = - 4
Thus the required value of the variable x is - 4

Option (A) is the correct answer: Panel a illustrate Increasing Return to Scale and panel b illustrate Constant Return to Scale.
Return to Scale:
It is the Variation or change in productivity that is the outcome from a proportionate increase of all the input.
Increasing Return to Scale:
An increasing return to scale occurs when the output increase by a larger proportion than the increase in inputs during the production process. For Example: if input is increased by 3 times but output increases by 3.75 times, then the firm or economy has experienced an increasing return to scale. This increase is due to many reasons like division external economies of scale.
Constant Return of Scale:
Constant Return of Scale refers to the production situation in which output increases exactly in the same proportion in which factors of production are increased. In simple words, if factors of production are doubled output will also be doubled. In this case, internal and external economies are exactly equal to internal and external diseconomies. This situation arises when after reaching a certain level of production, economies of scale are balanced by diseconomies of scale. For Example: A car wash in which one car wash takes 30 minutes. If there is one wash space and two workers running two 8 hours shifts total product would be 32.

Required percentage value = a
total value = b
Percentage = a/b x 100
