Vertical angles or contrary angles are the statement that Terra's proof is still absent. The angles formed opposite to each other when two lines cross each other are equal.

Terra describes the parallelogram nature of the diagram. Because they are vertical or opposite angles, these angles are equal.

The angles formed opposite to each other when two lines cross each other are equal. As a result, we have discovered that either vertical angles or opposite angles make up Terra's proof.

The equation of the linear function represented by the table below in slope-intercept form is y = 7x + 4

The equation of a line in point-slope form is expressed as y = mx + b

where

m is the slope

b is the intercept

Using the coordinate points (0,4) and (1, 11)

Slope = 11-4/1-0

slope = 7

The y-intercept is at the point (0,4)

Determine the equation

y = mx + b

y = 7x + 4

Hence the equation of the linear function represented by the table below in slope-intercept form is y = 7x + 4

3) CDAB is a parallelogram (a quadrilateral with two pairs of parallel sides is a parallelogram)

4) ∠B is congruent to ∠D (opposite angles of a parallelogram are congruent)

5) m∠B = m∠D (congruent angles)

6) m∠D=115° (transitive property)

7) m∠EDA=65° (linear pair)

8) m∠EAD=65° (base angle of an isosceles triangle)

9) m∠E = 50° (sum of angles in a triangle)

Answer:

Step-by-step explanation:

3 c = 1728

divide both sides by 3

c = 576

Calculate the lengths of the 3 sides of the triangle:

AB =

[tex] \sqrt{(7 - ( - 1)) ^{2} + (( - 2) - ( - 8))^{2} } = 10[/tex]

BC =

[tex] \sqrt{(( - 1) - 5) ^{2} + (( - 8) - 0)^{2} } = 10[/tex]

Answer:

The first answer is correct.  See the picture below

Step-by-step explanation:

The image of the points after they are reflected across the x-axis are J'(1, -9), K'(7, -4), L'(8, -13), M'(-2, -1)

From the question, we have the following parameters that can be used in our computation:

J(1, 9), K(7, 4), L(8, 13), M(-2, 1)

Also from the question we have the transformation to be

Transformation: reflection across the x-axis

The rule of the reflection across the x-axis is represented as

(x, y) = (x, -y)

Substitute the known values J(1, 9), K(7, 4), L(8, 13), M(-2, 1) in the above equation, so, we have the following representation

J'(1, -9), K'(7, -4), L'(8, -13), M'(-2, -1)

Hence, the image of the points are J'(1, -9), K'(7, -4), L'(8, -13), M'(-2, -1)

By unitary method, we get that the total cost of mixture per pound = 50 cents.

A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.

Given:

Cost of 1 pound sunflower seeds = 32 cents.

Cost of 1 pound cracked corn = 18 cents.

Available sunflower seeds = 10lb = 10 pounds

Available cracked corn = 16lb = 16 pounds

To find: Cost of the mixture per pound

Finding:

By unitary method, Cost of 1 pound sunflower seeds = 32 cents.

Cost of 10 pounds sunflower seeds = 32(10) = 320 cents.

Again, by unitary method,

Cost of 1 pound cracked corn = 18 cents.

Cost of 16 pound cracked corn

= 18(16) cents

= 288 cents.

Therefore, total cost of mixture per pound

Answer:

59. a₁ = 4

60. a₁ = 10

Step-by-step explanation:

The general equation for the sum of the first n terms Sₙ of a geometric sequence with common ratio r and first term a₁ is

[tex]S_n = a_1 \dfrac{1-r^n}{1-r}[/tex]    

Problem 59

Here we are given
[tex]S_n = \dfrac{31}{4}\\\\r = \dfrac{1}{2}[/tex]

So we can plug these values into the above equation and get [tex]a_1[/tex]

Let's first compute [tex]1 - r^n[/tex]
[tex]1 - r^n = 1 - \left(\dfrac{1}{2}\right)^5\\\\\left(\dfrac{1}{2}\right)^5 = \dfrac{1}{32}\\\\1 - r^n = 1 - \left(\dfrac{1}{2}\right)^5 = 1-\dfrac{1}{32} = \dfrac{32}{32}-\dfrac{1}{32} = \dfrac{31}{32}[/tex]

[tex]1- r = 1 - \dfrac{1}{2} = \dfrac{1}{2}[/tex]

So
[tex]\dfrac{1-r^n}{1-r} = \dfrac{31}{32} \div \dfrac{1}{2} = \dfrac{31}{32} \times \dfrac{2}{1} = \dfrac{31}{16}[/tex]

Substituting this value into [tex]S_n = a_1 \dfrac{1-r^n}{1-r}[/tex]  we get

[tex]\dfrac{31}{4} = a_1\dfrac{31}{16}[/tex]

Multiplying both sides by [tex]\dfrac{16}{31}[/tex]
[tex]\dfrac{31}{4} \times\dfrac{16}{31} = a_1\dfrac{31}{16} \times\dfrac{16}{31}\\\\4 = a_1 \textrm{or alternatively }\\ \\\boxed{a_1 = 4}[/tex]

Problem 60

Use the same technique as above

[tex]S_8 = 2550, r = 2\\\\S_8 = a_1 \times \dfrac{1-r^8}{1-r}\\\\\\2550 = a_1 \times \dfrac{1-2^8}{1-2}\\\\2550 = a_1 \times \dfrac{1 - 256}{1-2}\\\\2550 = a_1 \times \dfrac{-255}{-1}\\\\2550 = a_1 \times255\\\\== > a_1 = \dfrac{2550}{255}\\\\\boxed{a_1=10}[/tex]

If the main courses at a restaurant all contain rice or onion and of the 23 choices, 17 contain onion and 14 contain rice, then the number of dishes containing both rice and onion will be equal to 8.

The number of dishes that contain both rice and onion at the restaurant can be calculated by using an algebraic expression.

An algebraic expression can be defined as an equation in which both numerals and letters are present.

An algebraic expression for this problem can be given as,

(14 - x) + x + (17 - x) = 23

Here x is equal to the number of dishes containing both rice and onion.

14 + 17 - x + x - x = 23

A recycling center claims to give 96 cents for every 12 aluminum cans turned in. How much cents will they give if u recycled 96 cans?

Answer: XYW = 32, WYZ = 85

Step-by-step explanation:

We are looking for what x is, which we can find with the formula:

117 = (6x+44) + (-10x+65)

117 = -4x + 109

8 = -4x

x = -2

We can verify this is correct by plugging it in and seeing if they add up to 117.

6x + 44 (XYW)

= 6(-2) + 44

= -12 + 44

= 32

-10x + 65 (WYZ)

= -10(-2) + 65

= 20 + 65

= 85

32 + 85 = 117

Answer:
