Using a calculator, 1200/180 = 6.67 approximately

If you use long division, then you'll get what you see in the diagram below

The 6's go on forever after the decimal point, but if you round to two decimal places, then you'll get that approximate value of 6.67

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

If you want a remainder, then 1200/180 = 6 remainder 120

You can think of it like you having 1200 cookies and 180 friends. Each friend will get 6 whole cookies and there will be 120 left over as the remainder.

Answer:

1. Basically, a ratio is a relation between two values, such that the change of one value will result in the same proportional change in the other (if one value increases 6 times, or decreases 4 times, for example, the same will happen with the other value too.

Since Mrs. Jollie will save $60 for every two panels, then the ratio is:

2 panels: $60

Every ratio can be written in a form of fraction, by simply dividing these values:

2/60  

or, as a reduced fraction:

1/30

2. Now we are given several ratios, which we need to use to find price for 9 panels.

First way:

we can set a proportion because we already said that if we change one value, others will change proportionally as well. So, we take any of these ratios and make a proportion:

2 : $3,000 = 9 : $ x

Solving for x, we get:

x = $3,000 • 9 / 2

x = $13,500

Second way:

From the ratio, we can find the price for a single panel. Then, we simply multiply that with 9 and find the price for nine panels:

one panel costs $3,000 / 2 = $1,500

nine panels cost $1,500 • 9 = $13,500

3. Now, we are again given several ratios and we need to find the price per hour for each company. We can do this by simply dividing:

- ABC Co. 5h : $128

so, price per hour is $128/5 = $25.6

- Solar R' Us 6h : $181

so, price per hour is $181/6 = $30.17

- Light in the Sky 8h: $195

so, price per hour is $195/8 = $24.4

So, the best deal means that the price per hour is the lowest, so the best deal is the Light in the Sky company.

y is some number and it is equal to -4x+2

y being that same number is also equal to x-3

therefore, we can equate -4x+2 and x-3 to get x-3 = -4x+2

This is the same as starting with y = -4x+2 and replacing the y with x-3

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

Let's solve for x

x-3 = -4x+2

x-3+4x = -4x+2+4x .... add 4x to both sides

5x-3 = 2

5x-3+3 = 2+3 .... add 3 to both sides

5x = 5

5x/5 = 5/5 .... divide both sides by 5

x = 1

With this x value, you can now find the y value. Pick any equation that has x and y in it. If we picked the first equation, then

y = -4x+2

y = -4*1+2 ... plug in x = 1

y = -4+2

y = -2

Or we can pick the second equation

y = x-3

y = 1-3 .... plug in x = 1

y = -2

Final answer:

By using the elimination method to solve the given system of linear equations, we find that x = 18 and y = 15.

Explanation:

We are looking to solve the system of linear equations:

3x – 2y = 24

x + 2y = 48

To find the values of x and y, we can use substitution or elimination methods. In this case, the elimination method is very straightforward since the y coefficients in the two equations are additive inverses. If we add both equations together, the y terms will cancel out:

3x + x = 24 + 48

4x = 72

Dividing both sides by 4 gives us the value of x:

x = 18

To find y, we can substitute x back into either of the original equations. Let's use the second equation:

18 + 2y = 48

Subtracting 18 from both sides:

2y = 30

Dividing by 2:

y = 15

Thus, the solution to the system of equations is x = 18 and y = 15.

Opposite angles of a parallelogram are equal.

So [tex]3y^{\circ}=123^{\circ}[/tex]

⇒ y= [tex](\frac{123}{3})^ {\circ}[/tex]

and sum of adjacent angle is = [tex]180^{\circ}[/tex]

Therefore, [tex](2x-5)^{\circ} + 123^ {\circ}=180^{\circ}[/tex]

⇒[tex](2x-5)^{\circ} =180^{\circ}-123^ {\circ}[/tex]

⇒[tex]2x^\circ=57^\circ+5^\circ[/tex]

⇒x=[tex]31^\circ[/tex]

Therefore x=[tex]31^\circ[/tex] and y= [tex](\frac{123}{3})^ {\circ}[/tex]

The diagonals  of rectangle bisect each other.

so, 2x=x+9

⇔2x- x=9

⇔x = 9 units

Again opposite sides are congruent.

So,3y -9 =y+12

⇔3y - y =12+9

⇔y [tex]=\frac{21}{2}[/tex] units =10.5 units

Therefore x = 9 units and y = 10.5 units

19.

[tex]3x^\circ=45^\circ[/tex]         [∵ they are transversal angles]

⇔[tex]x=15^\circ[/tex]

And opposite sides are equal

7y = 4y + 21

⇔7y - 4y = 21

⇔3y = 21

⇔y = 7 units

Therefore [tex]x=15^\circ[/tex] and y = 7 units

Answer:

Angle 2=   110 degrees

Angle 3 =  70 degrees

Angle 4 = 70 degrees

Step-by-step explanation:

Finding angle 2

In the figure attached below,the angles 1 and 2  Corresponding angles

When two lines are crossed by another line that is  called the Transversal, then, the angles in matching corners are called corresponding angles.

Corresponding angles are equal so

angle 2 = 110 degrees

Finding angle 3

Similarly 2 and 3 are consecutive angles and Consecutive angles are supplementary . That is the sum of the consecutive angles is 180 degree

then

angle 2  +angle 3 = 180

110  + angle 3 = 180

angle 3 = 180 -110

angle 3 = 70 degrees

Finding angle 4

Now angle 3 and angle 4 are alternate interior angle and they are equal

angle 3 = angle 4

so angle 4 is 70 degree

Step-by-step explanation:

Distributive property of Addition:

                            a(b + c) = ab + bc

In other words, 'a' is distributed over 'b' and 'c'.

Also, note that a mixed fraction, of the form [tex]$ \textbf{c} \frac{\textbf{x}}{\textbf{y}} = \textbf{c} + \frac{\textbf{x}}{\textbf{y}} $[/tex]

If a mixed fraction is of the type [tex]$ \textbf{-p}\frac{\textbf{q}}{\textbf{r}} \hspace{1mm} \textbf{=} \hspace{1mm} \textbf{-(p + } \frac{\textbf{q}}{\textbf{r}}) \hspace{1mm} \textbf{=} \hspace{1mm} \textbf{-p} \hspace{1mm} \textbf{-} \hspace{1mm} \frac{\textbf{q}}{\textbf{r}} $[/tex]

OPTION A:

[tex]\textbf{3} \bigg ( \textbf{-4} \frac{\textbf{1}}{\textbf{2}} \bigg )[/tex]

This can be written as: [tex]$ 3 \bigg ( - 4 - \frac{1}{2} \bigg ) $[/tex]

Now, we distribute 3 over -4 and [tex]$ -\frac{1}{2} $[/tex].

[tex]$ = 3(-4) + 3\bigg (-\frac{1}{2} \bigg ) $[/tex]

Therefore, OPTION A is incorrect.

OPTION B: [tex]$ \textbf{2} \frac{\textbf{1}}{\textbf{4}} \bigg ( \textbf{1} \frac{\textbf{3}}{\textbf{4}} \bigg ) $[/tex]

Now, this is written as: [tex]$ 2 + \frac{1}{2} \bigg ( 1 + \frac{3}{4} \bigg ) $[/tex]

We have distribute 2 and [tex]$ \frac{1}{2} $[/tex] separately over 1 and [tex]$ \frac{3}{4} $[/tex].

So, we should have [tex]$ 2 (1) + 2 \bigg ( \frac{3}{4} \bigg ) + \frac{1}{2} (1) + \frac{1}{2}. \frac{3}{4} $[/tex]

So, OPTION B is incorrect.

OPTION C: [tex]$ \textbf{-4} \bigg( - 5 \frac{\textbf{1}}{\textbf{3}} \bigg ) $[/tex]

[tex]$ = - 4 \bigg ( -5 - \frac{1}{3} \bigg) $[/tex]

[tex]$ = -4(-5) + (-4) \bigg (- \frac{1}{3} \bigg ) $[/tex]

The expected number of bases for Ichiro Suzuki in a typical at-bat in 2001 is approximately 0.448, which rounds to 0.441 (Option D) to the nearest thousandth. Thus , the correct option is D.

To calculate the expected number of bases for Ichiro Suzuki in a typical at-bat in 2001, we can use the following formula:

E(X) = (0 ×P(Out)) + (1 × P(Single)) + (2 × P(Double)) + (3 × P(Triple)) + (4 ×P(Home Run))

First, we need to calculate the probabilities for each outcome:

P(Out) = (692 - 192 - 34 - 8 - 8) / 692 = 450 / 692 ≈ 0.651

P(Single) = 192 / 692 ≈ 0.278

P(Double) = 34 / 692 ≈ 0.049

P(Triple) = 8 / 692 ≈ 0.012

P(Home Run) = 8 / 692 ≈ 0.012

Now, plug these probabilities into the formula:

E(X) = (0 × 0.651) + (1 ×0.278) + (2 × 0.049) + (3 × 0.012) + (4 × 0.012)

E(X) ≈ 0.278 + 0.098 + 0.036 + 0.036 ≈ 0.448

Rounding to the nearest thousandth, E(X) is approximately 0.448.

So, the answer to the question is D. 0.441, which is the closest option provided.

Answer:

The relationship ⇒ 25x + 40y = 12,250

Step-by-step explanation:

The number of student memberships = x

The number of adult memberships = y

The monthly membership fee for a student = $25

The monthly membership fee for an adult = $40

The total fee = 25x + 40y

Al's Athletic Club receives $12,250 in membership fees for the month of January.

So, the relationship between x and y is:

25x + 40y = 12,250

For every 2 student memberships (2x$25=$50), there were 305 adult memberships.

To represent the relationship between the number of student memberships (2) and the number of adult memberships (y) at Al's Athletic Club for the month of January, we can use an equation based on the given information. Let's assume that there were 2 student memberships and y adult memberships in January. The monthly membership fees for students and adults are $25 and $40, respectively. The total membership fees collected for the month were $12,250.

The total fees can be represented as:

Total Fees = (Number of Student Memberships * Monthly Fee for Student) + (Number of Adult Memberships * Monthly Fee for Adult)

Using the given information, we can write the equation:

$12,250 = (2 * $25) + (y * $40)

Now, we can simplify this equation:

$12,250 = $50 + $40y

To isolate the variable y, we can subtract $50 from both sides of the equation:

$12,250 - $50 = $40y

$12,200 = $40y

Now, divide both sides by $40 to find the relationship:

y = $12,200 / $40

y = 305

So, the relationship between the number of student memberships (2) and the number of adult memberships (y) for the month of January is represented by the equation y = 305. This means there were 305 adult memberships in January for every 2 student memberships.
