Answer: zero and zero nineteenth thousandths

Step-by-step explanation:

The number 0.019 in expanded form is written as 0.010 + 0.009, which represents one-hundredth and nine-thousandths respectively.

The student is asking for the number 0.019 to be written in expanded form. Expanded form is a way to break down a number to show the place value of each digit. The number 0.019 in expanded form can be written as:

0.010 + 0.009

The first 0.010 represents one-hundredth and the second 0.009 represents nine-thousandths.

Answer:

His car's speed rate to the nearest thousandth of an hour is 100.489

Step-by-step explanation:

First: This is the only step, round the speed rate to the nearest thousandth:

When rounding always look at the place value they're telling you to round to and the place value to the right of it. Since, the question wants us to round to the nearest thousandth, look at the thousandths place but more specifically the place value to its right. The thousandths is the third digit behind the decimal point and the one to its right would be the fourth.

100.4893

So, if the number to the thousandths' right is less than 5 turn that number into a zero and keep the rest of the number the same. If the number is greater than or equal to 5 round up by making the number in the thousandths place a digit bigger.

Since 3 is smaller than 5, we'll turn the 3 into a zero and keep the rest the same.

100.4890

Since the zero is behind the decimal point and it is the number farthest to the left we can take it out.

100.489

Answer:

The change in the index is - 69/50

Step-by-step explanation:

* Lets explain what is the rational number

- A rational number is a number that can be expressed as a fraction

 a/b where a and b are integers and b ≠ 0

- A rational number have numerator and denominator

- Whole numbers, integers, fractions, terminating decimals and

 repeating decimals are all rational numbers

- The rational numbers includes all positive numbers, negative

  numbers and zero that can be written as a fraction

- To convert a Decimal to a Fraction follow these steps:

# Write down the decimal divided by 1

# Multiply both top and bottom by 10 for every number right the

  decimal point

# Simplify (or reduce) the fraction

* Lets solve the problem

- A stock market index drops by 1.38 points

- We need to find the rational number represents the change in

 the index

∵ Drop means the stock is become less

∴ The value of change will be negative

∵ The stock is drops by 1.38

∴ -1.38 = -1.38/1

- Multiply up and down by 100 because there are 2 digits right the

 decimal point

∴ -1.38 = -138/100

- Divide up and down by 2

∴ -1.38 = - 69/50

∴ The change in the index is - 69/50 (-1.38)

Answer: [tex]\dfrac{69}{50}[/tex]

Step-by-step explanation:

A rational number is in the form of [tex]\dfrac{p}{q}[/tex] , where [tex]q\neq0[/tex]. and p and q are integers.

Given : A stock market index drops by 1.38 points.

To convert 1.38 into rational , we divide and multiply it by 100 ( 1.38 is decimal expression up to hundredth) , we get

[tex]1.38\times\dfrac{100}{100}=\dfrac{138}{100}[/tex]

Now , we divide  numerator and denominator by 2 , we get

[tex]\dfrac{69}{50}[/tex]

Hence, the rational number represent the change in the index is [tex]\dfrac{69}{50}[/tex].

Answer:

3 / 4

Step-by-step explanation:

Answer:

a

Step-by-step explanation:

Given

2| x - 3 | + 5 = 17 ( subtract 5 from both sides )

2| x - 3 | = 12 ( divide both sides by 2 )

| x - 3 | = 6

The absolute value function always returns a positive value but the expression inside can be positive or negative, that is

x - 3 = 6 OR -( x - 3) = 6

x - 3 = 6 ( add 3 to both sides )

x = 9

OR

-( x - 3) = 6 ← distribute left side

- x + 3 = 6 ( subtract 3 from both sides )

- x = 3 ( multiply both sides by - 1 )

x = - 3

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

x = 9 → 2|9 - 3| + 5 = 2|6| + 5 = (2 × 6) + 5 = 12 + 5 = 17 ← True

x = - 3 → 2|- 3 - 3| + 5 = 2| - 6 | + 5 = (2 × 6) + 5 = 12 + 5 = 17 ← True

Hence x = 9 or x = - 3 are the solutions → a

Triangles are similar if their angles are congruent, supported by the AAA theorem. The similarity of triangles implies that the corresponding side lengths are proportional, which can be expressed algebraically or in words.

To justify that the triangles are similar, we look for congruent angles and proportional sides. The student indicated that the triangles have the same angles, which satisfies the AAA (Angle-Angle-Angle) similarity theorem. Because the angles are congruent, the sides are proportional, which means the ratios of corresponding sides are equal.

With words, we can express the relationship of corresponding lengths in similar triangles as the ratio of one triangle's side lengths to the other's. Algebraically, if we have corresponding sides a, b, and c from Triangle 1, and sides d, e, and f from Triangle 2, then a/d = b/e = c/f.

To solve for an unknown quantity, we algebraically isolate the variable in our equation, plug in the known values, calculate the answer, and then check to ensure the result is reasonable. For example, if we know sides a, b, d, and e, and we want to find side c, we would set up the proportion c/f = a/d, and after substituting the known values, we solve for c.

Answer:

C

Step-by-step explanation:

EFGH is a kite, so EF ≅ FG and EH ≅ HG.

The area of the kite consists of two area of triangles EFG and EHG.

1. Area of triangle EFG:

[tex]A_{\trangle EFG}=\dfrac{1}{2}\cdot EG\cdot h,[/tex]

where h is the height drawn from point F to the side EG.

1. Area of triangle EHG:

[tex]A_{\trangle EHG}=\dfrac{1}{2}\cdot EG\cdot H,[/tex]

where H is the height drawn from point H to the side EG.

3. Note that

[tex]EG \cong \text{rectangle's length}[/tex]

[tex]h+H\cong \text{rectangle's width}[/tex]

So,

[tex]A_{\text{kite }EFGH}\\ \\=A_{\triangle EFG}+A_{\triangle EHG}\\ \\=\dfrac{1}{2}\cdot EG\cdot (h+H)\\ \\=\dfrac{1}{2}\cdot \text{rectangle's length}\cdot \text{rectangle's width}\\ \\=\dfrac{1}{2}A_{\text{rectangle}}[/tex]

Thus, option C is true (the area of the kite doesn't depend on ratio in which points E and G divide the side)

Answer:

C.) The area of EFGH is always 1/2 of the area of the rectangle.

Any number plus 0 is the same as the first number.

Step-by-step explanation:

6 + 0 = 6, 8 + 0 = 8,9+ 0 = 9, 100 + 0 = 100.

Conclusion: Any number plus 0 is the number.

For example: x + 0 = x

x is the number.

Answer: 0

Step-by-step explanation:

100+0=100.

Just basic addition too. 100+0=100. That simple.

No other number can give off 100 like 0 can. 100 plus 0 just gives it the number itself.

Just like how 6+0=6. 6 is just being added to itself.

So, your answer for this is 0. No other number can give off a better answer than the 0 for this problem.

Answer:

y = -2

Step-by-step explanation:

You would use the Point-Slope Formula since we are given a point:

y - y₁ = m(x - x₁)

y + 2 = 0

y = -2

Because there was no rate of change [slope] given, it was automatically assumed to be a zero slope, which is a horizontal line.

Final answer:

The angle of rotation for rotational symmetry of a regular pentagon is 72°, which is found by dividing the full rotation of 360° by the number of sides (5).

Explanation:

The angle of rotation for rotational symmetry of a regular pentagon is the angle you rotate the pentagon until it looks exactly the same as it did before the rotation. A regular pentagon has five sides that are all of equal length, and the amount of rotation required to bring one vertex to the position of the next is 360° divided by the number of sides. Therefore, the angle of rotation for a regular pentagon is 360°/5, which equals 72°.

The answer would be {3, 5, 7, 9, 11, 13, 15}.

Answer:

$159.95

Step-by-step explanation:

Let price of trumphet be defined by [tex]x[/tex]

price of clarinet = $139.95

Number of clarinets sold = 19

Earning through clarinets' sale = [tex]19*139.95 = 2659.05[/tex]

Total earning of store = $4578.45

Earning through trumphets' sale = [tex]4578.45 - 2659.05 = 1919.40[/tex]

price of one trumohet = [tex]\frac{1919.40}{12} = 159.95[/tex]
