A. Using subtraction, the distance between the two birds = |-2.5 - 2.5| = |-5| = 5 meters.

B. Using additive inverses, the distance = 2.5 + 2.5 = 5 meters

The distance between any two points on a number line is the absolute difference of the coordinates of the two points.

The additive inverse of a number is the number that is added to the number to make it zero. For example, the additive inverse of a is -a.

Part A:

Using subtraction, the distance between the two birds = |-2.5 - 2.5| = |-5| = 5 meters.

Part B:

The additive inverse of -2.5 is 2.5.

Using additive inverses, the distance = 2.5 + 2.5

Using additive inverses, the distance = 5 meters

The solution to question 8, in scientific notation is  9.563 x 10¹¹.

The solution to question 9, in scientific notation is  9.83 x 10⁸.

The solution to question 10, in scientific notation is 1.35759 x 10⁹.

The solution to question 11, in scientific notation is  8.70366 x 10⁴.

Scientific notation is a form of presenting very large numbers or very small numbers in a simpler form.

(9.5 x 10¹¹) + (6.3 x 10⁹)

= (950 x 10⁹) + (6.3 x 10⁹)

= (950 + 6.3) x 10⁹

= 956.3 x 10⁹

= 9.563 x 10¹¹

(1.03 x 10⁹) - (4.7 x 10⁷)

= (103 - 4.7) x 10⁷

= 98.3 x 10⁷

= 9.83 x 10⁸

(1.357 x 10⁹) + 590,000

= (1.357 x 10⁹) + (5.9 x 10⁵)

= (13570 x 10⁵) + (5.9 x 10⁵)

= (13570 + 5.9) x 10⁵

= 13,575.9 x 10⁵

= 1.35759 x 10⁹

87,100 - (6.34 x 10¹)

= 87,100 - 63.4

The measure of each angle of the triangle is 40°, 40° and 100°.

What is the triangle?

Given:

In an isosceles triangle two of the three angles measure the same.

Let the two angles be equal to x.

The third angle is 20 more than twice the measure of either angle, which means 2x+20.

The angles of a triangle add up to 180 degrees.

(x)+(x)+(2x+20)=180

4x+20=180

4x=160

x=40 degrees

So, the two angles measure 40° each and the third angle would be,

2x+20

=2*40+20

=100°

Therefore, the measure of each angle of the triangle is 40°, 40° and 100°.

Step-by-step explanation:

Because a person who switch with 9 people, then another person switch with 8 people (because the first person was already counted), then another person who switch with 7 people (becsuse the first and the second person was already counted)... and you will get 9!. 9! is 9 factorial which is 9×8×7×6×5×4×3×2×1. :)

The total amount including the tax rate is found as $34.

For the stated conditions in the question.

The original amount = $31.69.

The tax rate is 6%.

The total mount will be the sum of original amount and tax price.

First calculated the tax price;

6% of 31.69 = 6×31.69/100

6% of 31.69 = 1.9014

Tax price = $1.9014.

Total price = original amount + tax price

Total price = $31.69 + 1.9014

Total price = 33.5914

Total price = $34 (Round to the nearest cent.)

Thus, the total amount is estimated as $34.

The correct option is D). The element is sodium, and it is highly reactive.

The atomic number of the element sodium (Na) is 11. It means that the sodium has 11 protons in total and because it is neutral it has 11 number of electrons.

Valence electrons (VE) refers to the electrons that usually presents in the outer shell of an atom. Thus, the sodium has only 1 valence electron.

Basically, the mass number of an element tells about the number of protons and neutrons in an atom and sodium is the atom that has 11 atomic number.

2. combine like terms

3. simplify on both sides

For the given sides AB and BC the angle included would always be Angle B

When we form a triangle we name the vertex as A, B and C. So, the sides AB and BC will always have an Angle B regardless of the naming convention we use.

A triangle is a polygon with three vertices and three edges that has three sides. It is a basic geometric shape. The term "abc" refers to a triangle containing the vertices a, b, and c. Any three non-collinear points in Euclidean geometry combine to create a singular triangle and a singular plane.

A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below. An example of a fraction is 8/25. 8 is the numerator and 25 is the denominator.

When Kyle finishes building the shed, he would have finished building a fraction of 1/1 of the shed. S

So, the amount of shed, that Kyle still needs to build to complete the shed is 1 ÷ 5/8

The solution of the radical equation of x is 1.

A linear equation in one variable is an equation which can be represented in the form of ax+b where x is the variable and 'a' is the coefficient and 'b' is  the two constants.

A radical equation is defined as an equation where the variable is under a radical or root.

We know that n-th root of a variable x can be written as x to the power of (1/n). Mathematically : [tex]\sqrt[n]{x} =x^{\frac{1}{n} }[/tex]

In the given equation:

∛x-1=√x-1

adding 1 to both sides we get:

or, ∛x=√x

Cross multiplying we get:

or, ∛x/√x =1

We know that (aˣ/aⁿ)=a⁽ˣ⁻ⁿ⁾

therefore :

or, [tex]x^{\frac{1}{3}-\frac{1}{2} }=1[/tex]

or, [tex]x^{-\frac{1}{6} }=1[/tex]

or, x=1

Hence the value of x in the radical equation is 1

The contrapositive statement is:

If x ≠ 2, then x^2 ≠ 4

And it is false.

First, we have two propositions:

p = "x^2 = 4"

q = "x = 2"

The contrapositive statement is:

¬q → ¬p

The negation of the propositions are:

¬q  = "x ≠ 2"

¬p = "x^2 ≠ 4"

Then the contrapositive statement with the given propositions is:

If x ≠ 2, then x^2 ≠ 4

Now, is this statement true?

No, because we can have:

x = -2 (which is different than 2, so the hypothesis is true)

and x^2 = (-2)^2 = 4

Then the conclusion is false, so the statement is false.

Answer:

x + y = 29   equation 1 

Five more than means add 5+5 three times the smaller number:

 3x equals the larger number:  = y 3x + 5 = y    equation 2

 From equation 1x + y = 29subtract x from both sidesy = 29 - x 

We now have two things that are both equal tothe larger number y.

  They must be equal to each other. 
3x + 5 = 29 - x

 Add x to both sides 3x + x + 5 = 29 - x + x4x + 5 = 29

subtract 5 from both sides 4x + 5 - 5 = 29 - 54x = 24

divide both sides by 44x/4 = 24/4x = 6 

We now know x = 6

We also know y=29-x y = 29 - 6y = 23
