Answer:20/24

Step-by-step explanation:

To find the fraction of members that voted yes, we need to divide the number of members that voted yes by the total number of members.
Given:
- Total number of members (two dozen): 1 dozen is 12 members, so two dozen is 2 x 12 = 24 members.
- Number of members that voted 'yes': 20 members.
Now, to find the required fraction, we perform the following division:
Fraction of members that voted yes = (Number of members that voted 'yes') / (Total number of members)
                                   = 20 / 24
This fraction can be simplified to its lowest terms by dividing both the numerator (20) and the denominator (24) by their greatest common divisor (GCD), which is 4:
Simplified fraction = (20 ÷ 4) / (24 ÷ 4)
                    = 5 / 6
Therefore, the fraction of members that voted yes is 5/6.

The necessary conditions are: B. Opposite sides are parallel, A. Alternate interior angles, and D. Alternate interior angles are supplementary.

To prove that the opposite sides of a parallelogram are congruent, the following conditions are necessary:

1. **Opposite sides are parallel (Option B)**: This is a fundamental property of parallelograms. Parallel sides ensure that corresponding angles are congruent and alternate interior angles are congruent.

2. **Alternate interior angles (Option A)**: If the opposite sides are parallel, then alternate interior angles will be congruent. This property is essential in establishing the equality of corresponding sides.

3. **Alternate interior angles are supplementary (Option D)**: This property is crucial in proving the congruence of opposite sides. It guarantees that when opposite angles are equal, the opposite sides will also be equal.

Therefore, the correct options are A, B, and D. These conditions collectively ensure the congruence of opposite sides in a parallelogram.

Answer:

y = -5x + 46

Step-by-step explanation:

We are trying to find an equation in y=mx+b form

Okay so we know two points on the graph,  from which we can get the slope (value of m) by the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]

plugging in the values:  [tex]\frac{6 -1}{8-9}[/tex]

the resulting slope is -5

to find our b value we can plug in one of our coordinants into the equation and solve for b

1 = -5(9) + b

1 = -45 + b

46 = b

so our equation in y = -5x + 46

Answer:

(6,-2)

Step-by-step explanation:

2x + 3y = 6

 x + y = 4

Multiply the second equation by -2 to eliminate x

-2(x+y) = -2*4

-2x-2y = -8

Add this to the first equation

2x + 3y = 6

-2x -2y = -8

---------------------

       y = -2

Now we need to find x

x+y = 4

x-2 = 4

Add 2 to each side

x-2+2 = 4+2

x = 6

(6,-2)

Answer:

(6,-2)

Step-by-step explanation:

Given equations are [tex]2x + 3y = 6[/tex] and [tex]x + y = 4[/tex].

Solve 2nd equation  [tex]x + y = 4[/tex] for y

[tex]x + y = 4[/tex]

[tex]y = 4-x[/tex] ...(i)

Plug value of y from equation (i) into first equation  [tex]2x + 3y = 6[/tex]

[tex]2x + 3(4-x) = 6[/tex]

[tex]2x + 12-3x = 6[/tex]

[tex]12-x = 6[/tex]

[tex]-x = 6-12[/tex]

[tex]-x = -6[/tex]

[tex]x = 6[/tex]

Plug x=6 into equation (i)

[tex]y = 4-x[/tex]

[tex]y = 4-6[/tex]

[tex]y = -2[/tex]

Hence final answer is x=6, y=-2 or we can write that in (x,y) form as (6,-2)

Answer:

The solution to this system is (4, 1/6).

Step-by-step explanation:

Please separate these two equations for clarity.  I like to write them in column format:

2.5y + 3x = 27

5x – 2.5y = 5

---------------------

8x           = 32, and x = 4.

Subbing 4 for x in the second equation yields 5(4) - 2.5y = 5.

Then 20 - 2.5y = 5, or 15 = 2.5y.  Solving for y, we get y = 1/6.

The solution to this system is thus (4, 1/6).

Answer: The resultof adding the two equations is 3x= 32.  

The solution to the system is ( 4; 6).

Step-by-step explanation:

Hi, first we add the two equations.

2.5y + 3x =27

+

-2.5y +5x   = 5

----------------------

8x= 32

The resultof adding the two equations is 3x= 32

the next step is solving the equation:

8x= 32

x=32/8

x= 4

Substituting the value of x in any of the original equations:

2.5y +3x= 27

2.5y +3(4) =27

2.5y +12=27

2.5y  = 27-12

2.5y = 15

y= 15/2.5

y=6

So, the solution to the system is ( 4; 6)

Associative property of addition

Step-by-step explanation:

We are given the statement [tex] ( a + b ) + c [/tex] and we are to determine whether which of the given answer options allows it to be written as [tex] c + ( a + b ) [/tex].

According to the associative property of addition, you can add the numbers regardless of how they are grouped.

Therefore, (a + b) + c = c + (a + b) is possible with associative property of addition.

The answer is commutative - addition!

The reason it is not associative is because while the direction changes, the parentheses does not move! In the associative, the parenthesis moves, but in (a + b) + c = c + (a + b), the parenthesis contains a + b in both of them. Also here is some picture proof. (Attached)

Answer:

x = -7 and x = 3

Step-by-step explanation:

x² + 4x - 21 = 0 factors as follows:  (x + 7)(x - 3) = 0.

Then x = -7 and x = 3.

Answer:

[tex]x = 3\\x = -7[/tex]

Step-by-step explanation:

We have the following quadratic equation

[tex]x^2 + 4x - 21 =0[/tex]

To solve the equation we must factor it.

To factor the equation we must find 2 numbers b and c that when adding them, you obtain as result 4 ([tex]c + b = 4[/tex]) and when multiplying them, you obtain as result -21 ([tex]c * b = -21[/tex]).

Then the polynomial will be factored in the following way:

[tex](x+c)(x + b) = 0[/tex]

You can verify that the numbers that meet this condition are:[tex]b = 7\\c = -3[/tex]

So

[tex]x^2 + 4x - 21 =(x-3)(x + 7)=0[/tex]

Finally the solutions are:

[tex]x = 3\\x = -7[/tex]

arctan(2.6) = 68.96

Step-by-step explanation:

To find the arctan of 2.6, we are going to use calculator:

Then, we have that arctan(2.6) = 68.96.

The principal value of arctan(2.6) is 1.231 radians or approximately [tex]70.43^o[/tex].

The arctan function, also known as the inverse tangent function, is the inverse of the tangent function. It is denoted as arctan(x), atan(x), or tan^(-1)(x).

The arctan function takes a real number as input and returns the angle whose tangent is equal to that number. In other words, if y = arctan(x), then tan(y) = x.

In other words, the principal value of arctan refers to the primary angle within a specific range for which the tangent function yields a given value. In the case of arctan(2.6), we are seeking the principal angle whose tangent is equal to 2.6.

We can determine the principal value of arctan(2.6) to be approximately 1.231 radians or approximately [tex]70.43^o[/tex]. It is important to note that the angle can be expressed in either radians or degrees, depending on the desired unit of measurement.

Answer:

Hence final answer is [tex]x<-8[/tex] or [tex]x>\frac{1}{5}[/tex]

correct choice is B because both ends are open circles.

Step-by-step explanation:

Given inequality is [tex]\frac{x+8}{5x-1}>0[/tex]

Setting both numerator and denominator =0 gives:

x+8=0,  5x-1=0

or x=-8, 5x=1

or x=-8, x=1/5

Using these critical points, we can divide number line into three sets:

[tex](-\infty,-8)[/tex], [tex]\left(-8,\frac{1}{5}\right)[/tex] and [tex](\frac{1}{5},\infty)[/tex]

We pick one number from each interval and plug into original inequality to see if that number satisfies the inequality or not.

Test for [tex](-\infty,-8)[/tex].

Clearly x=-9 belongs to [tex](-\infty,-8)[/tex] interval then plug x=-9 into [tex]\frac{x+8}{5x-1}>0[/tex]

[tex]\frac{-9+8}{5(-9)-1}>0[/tex]

[tex]\frac{-1}{-46}>0[/tex]

[tex]\frac{1}{46}>0[/tex]

Which is TRUE.

Hence [tex](-\infty,-8)[/tex] belongs to the answer.

Similarly testing other intervals, we get that only [tex](-\infty,-8)[/tex] and [tex](\frac{1}{5},\infty)[/tex] satisfies the original inequality.

Hence final answer is [tex]x<-8[/tex] or [tex]x>\frac{1}{5}[/tex]

correct choice is B because both ends are open circles.

Answer:

[tex]x \:<\:-8[/tex] or  [tex]x \:>\:\frac{1}{5}[/tex].

Step-by-step explanation:

The given inequality is [tex]\frac{x+8}{5x-1} \:>\:0[/tex]

For this statement to be true, then we must have the following cases:

Case 1

[tex]x+8 \:<\:0\:and\:5x-1\:<\:0[/tex]

[tex]x \:<\:-8\:and\:x\:<\:\frac{1}{5}[/tex]

The intersection of these two inequalities is [tex]x \:<\:-8[/tex].

The solution to this first case is  [tex]x \:<\:-8[/tex].

Case 2

[tex]x+8 \:>\:0\:and\:5x-1\:>\:0[/tex]

[tex]x \:>\:-8\:and\:x\:>\:\frac{1}{5}[/tex]

The intersection of these two inequalities is [tex]x \:>\:\frac{1}{5}[/tex].

The solution to this second case is  [tex]x \:>\:\frac{1}{5}[/tex].

Therefore the solution to the given inequality is

[tex]x \:<\:-8[/tex] or  [tex]x \:>\:\frac{1}{5}[/tex].

The equation for the annual driving cost, C, in terms of d, the number of miles driven is C = 0.125 d + 5000.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

annual cost of driving = $5000 per year

operating costs of car =  12.5 cents per mile = $0.125

Let total distance drive annually be dmile

So, operating costs of car annually  = $0.125 of total distance drive

⇒operating costs of car annually  = $0.125  of d

⇒operating costs of car annually  = $0.125 d

So,  equation for the annual driving cost, C, in terms of d, the number of miles driven is given as,

annual driving cost, C = operating costs of car annually + annual cost of driving

⇒ C = 0.125 d + 5000

Hence,The equation for the annual driving cost, C, in terms of d, the number of miles driven is C = 0.125 d + 5000.

The expression representing the length of a rectangle could vary depending on context, such as using graph measurements (Δx = 41 m), significant figures (1.25 cm), or scaling factors (4 inches × 2 = 8 inches).

To determine the expression that represents the length of a rectangle, we generally use the formula for the perimeter or area, depending on what information is available. In this case, information provided suggests different scenarios involving measurements and area calculations. From one scenario, the length of a rectangle is calculated using graph paper measurements, resulting in Δx = 41 m. In another scenario, we're given information about a rectangle's width being 1.25 cm with three significant figures.

In physics-related contexts, references to frame of reference and speed c suggest considering displacement in spacetime, though this might not relate directly to the geometrical dimensions of a rectangle. Lastly, one mention involves the scaling up by a factor, such as a square with side length doubled, resulting in a side length expression of 4 inches × 2 = 8 inches. Without further context, it is not possible to provide a definitive expression for the length of a rectangle.

43785 is not divisible by 2 because it's not an even number, and this also means it's not divisible by 10 because 10 = 2*5.

The sum of its digits is 4 + 3 + 7 + 8 + 5 = 27, which is divisible by 3 since 27 = 3*9, so 43785 is divisible by 3. We have 43785 = 3*14595.

It would be divisible by 9 if 14595 were also divisible by 3. That number has digital sum 1 + 4 + 5 + 9 + 5 = 24, which is divisible by 3, so 14595 is too and 14595 = 3*4865. So 43785 = 9*4865, and it is indeed divisible by 9.

14595 is clearly divisible by 5 because its ends with a 5.
