2 and 200

10 and 100

13 and 52

one thousand and one million

Answer:

m<2 = 63

m<3 = 117

Step-by-step explanation:

<1 and <2 are alternate interior angles and are therefore equal. M<1 = 63 degrees,  so m<2 must be the same thing.

<2 and <3 are on the same straight line.

They are supplementary.

Therefore they equal 180 degrees.

63 + m<3 = 180                  Subtract 63 from both sides.

63 - 63 +m<3 = 180 - 63   Collect like terms

m<3 = 117

Answer:

28 miles per gallon

Step-by-step explanation:

you divide 420 by 15 to see how many miles per gallon and

420 divided by 15= 28 (gallons)

28 miles I think I’m not sure but just divide 15 into 420 and you should get the answer.

Answer:   A. Line segment

Step-by-step explanation:

A line is a one-dimensional geometric straight -undefined figure which has no thickness or depth . It extends infinitely in both directions.  

A line segment is a part of a line having end-points on both the sides.

It has only length therefore, it is one dimensional.

Thus , the objects is considered to be one-dimensional because it has length but no width or height is a line segment.

The triangle is 2-dimensional , point has no-dimensions,  and cube  is 3-dimensional.

A line segment is the correct answer, as in mathematics it is considered one-dimensional because it only has length but no width or height. It extends in one direction, unlike a triangle and a cube, which have more dimensions. The point does not have length.

In mathematics, a line segment is considered to be one-dimensional as it only possesses a property of length but no width or height. This means it only extends in one direction, often represented on a number line. In comparison, other options presented such as a triangle, point or cube have other dimensions involved. Specifically, a triangle falls in two dimensions as it has both length and width; a cube is a three-dimensional object possessing length, width, and height; and a point, though it lacks all three dimensions, is not accurate as it doesn't have length, which is the key criterion in the question.

Answer:

The answer is 0.42525 TONS (METRIC)

North Carolina = 3 * Utah

North Carolina = 2 * Oregon

Arkansas = Oregon - 1,000,000

North Carolina + Utah + Oregon + Arkansas = 27,000,000

North Carolina = 3 * Utah

Utah = 1/3 * North Carolina

Utah = 1/3 * (2 * Oregon)

(2 * Oregon) + (1/3 * (2 * Oregon)) + Oregon + (Oregon - 1,000,000) = 27,000,000

2O + (1/3 * 2O) + O + O - 1,000,000 = 27,000,000

2O + 2/3O + O + O - 1,000,000 = 27,000,000

4 2/3 O - 1,000,000 = 27,000,000

4 2/3 O = 28,000,000

O = 6,008,584

NC = 2O

NC = 2(6,008,584)

NC = 12,017,167

A = O - 1,000,000

A = 6,008,584 - 1,000,000

A = 5,008,584

NC = 3U

12,017,167 = 3U

U = 4,005,722

The populations of the four states are as follows:

- Utah has a population of 4 million.

- Oregon has a population of 6 million.

- North Carolina has a population of 12 million.

- Arkansas has a population of 5 million.

Let's denote the population of Utah, Oregon, and Arkansas as U, O, and A, respectively. According to the information given:

1. North Carolina has three times the population of Utah: [tex]\( NC = 3U \).[/tex]

2. North Carolina has twice the population of Oregon: [tex]\( NC = 2O \).[/tex]

3. Arkansas has 1 million people fewer than Oregon: [tex]\( A = O - 1 \).[/tex]

4. The total population of these four states is 27 million: [tex]\( U + O + A + NC = 27 \).[/tex]

From equations (1) and (2), we can equate the populations of Utah and Oregon since both are related to the population of North Carolina:

[tex]\( 3U = 2O \) or \( O = \frac{3}{2}U \).[/tex]

Now, substitute the value of O from equation (3) into the total population equation (4):

[tex]\( U + \frac{3}{2}U + ( \frac{3}{2}U - 1 ) + 3U = 27 \).[/tex]

Combine like terms:

[tex]\( U + \frac{3}{2}U + \frac{3}{2}U - 1 + 3U = 27 \),[/tex]

[tex]\( U + 3U + 3U - 1 = 27 \),[/tex]

[tex]\( 7U - 1 = 27 \).[/tex]

Now, solve for U:

[tex]\( 7U = 27 + 1 \),[/tex]

[tex]\( 7U = 28 \),[/tex]

[tex]\( U = \frac{28}{7} \),[/tex]

[tex]\( U = 4 \)[/tex] million.

Now that we have the population of Utah, we can find the populations of the other states:

[tex]\( O = \frac{3}{2}U = \frac{3}{2} \times 4 = 6 \)[/tex] million,

[tex]\( NC = 2O = 2 \times 6 = 12 \)[/tex] million,

[tex]\( A = O - 1 = 6 - 1 = 5 \)[/tex] million.

that is true if that's 1/3n=7/12

if it's 1/3n-7/12 then the first step is to equal it to zero

Yes, the second step in solving 1/3n = 7/12 is to divide both sides of the equation by 1/3.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In a fraction say (x/y), [y] is called denominator.

We have the equation -

(1/3)n = (7/12)

We have -

(1/3)n = (7/12)

Dividing both sides by (1/3), we get -

[(1/3)/(1/3)]n = [7/12 x 3]

n = 7/4

Therefore, yes, the second step in solving 1/3n = 7/12 is to divide both sides of the equation by 1/3.

Answer:

The answer is C, 220 units.

Answer:

The answer is the third

S = 16 t²

Step-by-step explanation:

* Lets study the order pairs in C to find what is the relation

  between the input (t) and the output (S)

∵ C = {(t , S): (0 , 0) , (1 , 16) , (2 , 64) , (3 , 144) , .............}

∵ (0 , 0) is the first point

∴ There is no plus or minus in the relation between S and t

∴ We refused the last answer S = 16(t + 1)² because

  if t = 0 then S = 16(0 + 1) = 16 ≠ 0

- If we chose the first answer:

∵ S = 16t  

∵ t = 0 ⇒ S = 16(0) = 0 ⇒ its right

∵ t = 1 ⇒ S = 16(1) = 16 ⇒ its right

∵ t = 2 ⇒ S = 16(2) = 32 ⇒ its wrong

∴ We refused the first answer

- If we chose the second answer:

∵ S = (16t)²

∵ t = 0 ⇒ S = (16×0)² = 0 ⇒ its right

∵ t = 1 ⇒ S = (16×1)² = 256 ⇒ wrong

∴ We refused the second answer

- If we chose the third answer:

∵ S = 16 t²

∵ t = 0 ⇒ S = (16)(0)² = 0 ⇒ its right

∵ t = 1 ⇒ S = (16)(1)² = 16 ⇒ its right

∵ t = 2 ⇒ S = (16)(2)² = 16 × 4 = 64 ⇒ its right

∵ t = 3 ⇒ S = (16)(3)² = 16 × 9 = 144 ⇒ its right

∴ every time we multiply 16 by the square of the value of t

∴ We accept the third answer

Area of circle = [tex]\pi[/tex][tex]r^{2}[/tex]

First, we can put in our values. For now, we can leave [tex]\pi[/tex] alone.

Our radius is 5.5 so we have to square it which gives us a product of 30.25

then, we can multiply our radius squared by [tex]\pi[/tex] and we get

Area, A = 95.033177771091 [tex]in^{2}[/tex]

Answer:

The wall is 3 ft high and 5 ft long.

Step-by-step explanation:

Recall:  Area of the rectangular wall is A = (length)(height).

Let the height be represented by h.  Then the length is represented by h + 2.

The formula A = (length)(height) then becomes A = h(h+2) = 15 ft², which, written in the standard form of a quadratic equation, is h² + 2h - 15 = 0.

Let's solve this last equation for h using completing the square:

h² + 2h - 15 = 0 becomes h² + 2h + 1 -1 - 15 = 0, or (h + 1)² = 16.  Taking the square root of both sides, we get:

h + 1 = ±4, which is equivalent to h = 3 and h = -5.  Discard the negative result.  Then h = 3 and w = 3+2 = 5.

The wall is 3 ft high and 5 ft long.  Its area is (3 ft)(5 ft) = 15 ft²

The height and the length of the rectangular wall is 3 feet and 5 feet respectively.

Area of a rectangle = 15 square feet

Length = x feet

Height = (x - 2) feet

Area of a rectangle = height × length

15 = x × (x - 2)

15 = x² - 2x

set to quadratic equation

x² - 2x - 15 = 0

x² - 5x + 3x - 15 = 0

x(x - 5) + 3(x - 5) = 0

(x + 3)(x - 5) = 0

x + 3 = 0 or x - 5 = 0

x = -3 or x = 5

The length of a rectangle cannot be negative

Therefore,

Length = x feet

= 5 feet

Height = (x - 2) feet

= 5 - 2

= 3 feet

[tex]90cm^2[/tex]

Step-by-step explanation:

The side length AB of triangle ABC corresponds to side length of PQ of triangle PQR.

The scale factor from ABC to PQR is [tex]k=\frac{6}{4}=1.5[/tex]

The area of triangle PQR will change by [tex]k^2=1.5^2=2.25[/tex] centimeters square.

Since we know the area of triangle ABC to be [tex]40cm^2[/tex], the area of triangle PQR [tex]=2.25\times 40=90cm^2[/tex]

Answer:

The area of the triangle PQR is 90 cm^2.

Step-by-step explanation:

We are given two triangles, ABC and PQR, which are similar to each other.

If two triangles are similar, then the ratio of their areas is the square of the ratio of their sides.

Given that area of the triangle ABC is [tex]40cm^2[/tex], we are to find the area of the triangle PQR.

Finding the scale factor [tex]k=\frac{6}{4} =1.5[/tex]

So square of this scale factor will be [tex]k^2=(1.5)^2=2.25[/tex]

Area of triangle PQR = [tex]2.25 \times 40[/tex] = 90cm^2
