Answer:

1)  y = 6

2) Paul has 20 quarters

Step-by-step explanation:

The relationship between the ∠4 and ∠6 is that both are alternate interior angle.

Given,

The angles = ∠4 and ∠6

Here,

The ∠4 and ∠6 lie on the opposite sides of the transversal and both are nonadjacent interior angles

So, ∠4 and ∠6 are alternate interior angle.

Hence, The relationship between the ∠4 and ∠6 is that both are alternate interior angle.

Answer:

6 inches

Step-by-step explanation:

it's just 36/6 which equals 6

The dimensions of the sticker are 6 centimeters and 9 centimeters, respectively.

According to the statement, we find a rectangular sticker whose perimeter and area are known. By the perimeter and area formulas of the rectangle we have the following system of equations:

x · y = 54                      (1)

2 · (x + y) = 30              (2)

By (2):

2 · x + 2 · y = 30

2 · x = 30 - 2 · y

x = 15 - y

(2) in (1):

(15 - y) · y = 54

15 · y - y² = 54

y² - 15 · y + 54 = 0

(y - 9) · (y - 6) = 0

The solutions are y₁ = 9 and y₂ = 6, respectively.

By (2):

x₁ = 15 - y₁

x₁ = 15 - 9

x₁ = 6

x₂ = 15 - y₂

x₂ = 15 - 6

x₂ = 9

The solutions are x₁ = 6 and x₂ = 9, respectively.

The dimensions of the sticker are 6 centimeters and 9 centimeters, respectively.

Answer:

x= -(2y+7)/(4)

Step-by-step explanation:

4x+2y=7

4x = -2y+7

x= -(2y+7)/(4)

Answer:

x = [tex]\frac{7-2y}{4}[/tex]

Step-by-step explanation:

4x + 2y = 7 ( subtract 2y from both sides )

4x = 7 - 2y ( divide both sides by 4 )

x = [tex]\frac{7-2y}{4}[/tex]

The equation of the line which is perpendicular to 2x - y = 4 and passing through (4, 1) will be y = (-1/2)x + 3

Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.

The equation of the line is given below.

2x - y = 4

Then the slope of the perpendicular line will be

y = 2x - 4

m = 2

Then the equation of line will be

y = -(1/2)x + d

Then the line is passing through (4, 1), then we have

1 = -(1/2)4 + d

3 = d

The equation of the line which is perpendicular to 2x - y = 4 and passing through (4, 1) will be y = (-1/2)x + 3

The required value of x is 4 by using constant of proportion.

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of y

When a quantity varies directly with others, then we have a relation, y = kx, where k is the constant of the proportion      —-- 1

Now, find k for given x = 2 and y = 6, we need to put these values in equation 1, i.e.

6 = k(2)

k = 6/2

k = 3

Further calculate x for given y = 12 and constant of variation = 3 i.e.

12 = (3)x

x = 4

Hence, the required value of x is 4.

Triangle classification will always help us to prove congruency in triangle. Each of the three angles in an acute triangle is acute. One right angle and two acute angles make up a right triangle. Additionally, an obtuse triangle has two acute angles and one obtuse angle.

The triangles are congruent when two sets of corresponding sides and the corresponding angles between them are in agreement. Two triangles that have a congruent angle in the middle and two congruent sides.

Instead of using the unit measure, it is based on the proportion of the side lengths to one another. As a result, triangles are categorized according to how many of their sides are the same length as one another or not at all equal.

Angles are another way to categorize triangles. Each of the three angles in an acute triangle is acute (less than 90 degrees). One right angle and two acute angles make up a right triangle. Additionally, an obtuse triangle has two acute angles and one obtuse angle (greater than 90 degrees).

Luis and Baca would be the same weight after 60 weeks of weightlifting.

A linear equation is one in which the highest power of the variable is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation.

To create an equation that Luis and Baca can use to determine how long it will take for them to be the same weight:

Let the time taken by Luis and Baca to be of the same weight be x weeks,

Given:

Initial weight of Luis = 194 pounds

Initial weight of Baca = 218 pounds

Then,

Weight gained by Luis in x weeks = 0.6x pounds

Weight gained by Baca in x weeks = 0.2x  pounds

Total weight of Luis after x weeks = (194 + 0.6x ) pounds

Total weight of Baca after x weeks = (218 + 0.2x) pounds

For Luis and Baca to be of the same weight,

Total weight of Luis after x weeks = Total weight of Baca after x weeks

Therefore, we equate the total weight gained by Luis and Baca after x weeks to determine the value of x

⇒ 194 + 0.6x  = 218 + 0.2x

⇒ 0.6x - 0.2x =218 - 194

⇒ 0.4x = 24

⇒ x = 60

Hence, Luis and Baca would be the same weight after 60 weeks of weightlifting.

An infinite geometric series is the outcome of an unlimited geometric sequence. If the value of S = 12 and r = 1/6 then the value of a₁ = 10.

An infinite geometric series is the outcome of an unlimited geometric sequence. This series wouldn't have a finish. It is possible to calculate the sum of all finite geometric series. The terms in the sequence will grow steadily larger, but adding the larger numbers together will not provide a solution if the common ratio of an infinite geometric series is greater than one.

The sum of an infinite geometric series be S = a/1-r

S be the sum = 12

a₁ be the first term = ?

r -be the common ratio = 1/6

We know,

S = a₁/1-r

substitute the values in the above equation, we get

12 = a₁/1-(1/6)

simplifying the equation,

12 = 6a₁/5

a₁ = 60/6 = 10

Given the area, the equation that Noor should use to determine the width of pen is x² + 3x = 70.

The length and width of the rectangular pen are 10m and 7m respectively.

The area of a rectangle is expressed as;

A = l × w

Where l is length and w is width.

Given the data in the question;

Let the width of the rectangular pen be 'x'

To determine the equation that Noor will use to find the width of the pen, plug the values into the equation above.

A = l × w

70 = (x+3) × x

70 = x² + 3x

x² + 3x = 70

We can go further and solve for the width of the pen.

x² + 3x = 70

x² + 3x - 70 = 0

Factor sing AC method; find two integer whose addition gives 3 and multiplication gives -70.

-7 and 10

(x-7) (x+10) = 0

x - 7 = 0, x + 10 = 0

x = 7, x = -10

But the dimension of the width can not be negative.

Hence

x = 7

Width = x = 7m

Length x + 3 = 7 + 3 = 10m
