Answer:

see explanation

Step-by-step explanation:

Let ∠4 be x then ∠6 is [tex]\frac{1}{8}[/tex] x

∠4 and ∠6 are same side interior angles and are supplementary, thus

x + [tex]\frac{1}{8}[/tex]x = 180

Multiply through by 8 to clear the fraction

8x + x = 1440, that is

9x = 1440 ( divide both sides by 9 )

x = 160

Hence ∠4 = 160° and ∠6 = 160° ÷ 8 = 20°

Answer:

[tex]m \angle 4 = 160 \°\\m \angle 6 = 20 \°[/tex]

Step-by-step explanation:

From the graph, we can say that

[tex]m \angle 6 + m \angle 4 = 180 \°[/tex]

Because they are consecutive interior angles, and they sum 180° by definition. So, the reason of third statement is "by definition of consecutive interior angles".

We already know that

[tex]m \angle 6 = \frac{1}{8} \times m \angle 4[/tex]

But,

[tex]m \angle 6 + m \angle 4 = 180 \°\\m \angle 6 = 180\° - m \angle 4[/tex]

Replacing this, we have

[tex]180\° - m \angle 4=\frac{1}{8}(m \angle 4)\\(\frac{1}{8}+1) (m\angle 4)=180\°\\\frac{9}{8}(m\angle 4) = 180 \°\\ m \angle 4 = \frac{180(8)}{9}= 160\°[/tex]

Then,

[tex]m \angle 6 + m \angle 4 = 180 \°\\m \angle 6 + 160\° =180\°\\m \angle 6 = 180-160=20[/tex]

Therefore, the measures of these two angles are

[tex]m \angle 4 = 160 \°\\m \angle 6 = 20 \°[/tex]

Answer: The value of x is 40

Step-by-step explanation:

Given triangle SRT,

Angle SRT = 20 and Angle SRT = Angle STR

To find Angle STU:

We know that

The sum of all interior angles of triangle is equal to 180.

Angle SRT + Angle STR + Angle RST =180

Also, Angle SRT = Angle STR =20

20+20+Angle RST=180

Angle RST=140.

Now. The exterior angle of triangle is equal to sum of opposite interior angles of triangle,

Angle STU=4x=Angle RST+Angle SRT

4x=20+140

4x=160

x=40

Therefore, The value of x is 40

The area of pasture is 60000 square feet.

Step-by-step explanation:

Perimeter of rectangular pasture = 1000 feet

Width of pasture = w

Length of pasture = l = w+100

We know that,

Perimeter = 2(Length+width)

[tex]1000=2(w+100+w)\\1000=2(2w+100)\\1000=4w+200\\1000-200=4w\\800=4w\\4w=800[/tex]

Dividing both sides by 4

[tex]\frac{4w}{4}=\frac{800}{4}\\w=200[/tex]

Width is 200 feet.

Length = w+100 = 200+100 = 300 feet

Area of pasture = A = Length * Width

[tex]Area\ of\ pasture=300*200\\Area\ of\ pasture=60000 \ ft^2[/tex]

The area of pasture is 60000 square feet.

The question is about calculating the area of a rectangular pasture given its perimeter and relation between its length and width. After setting up equations based on the given conditions and calculating, the area of the pasture is found to be 60,000 square feet.

The subject of this question is Mathematics, specifically dealing with the calculation of area from given perimeter and length-width relationship in a rectangle. Let's denote the width of the rectangular pasture as 'w', and its length would then be 'w+100'.

The formula for the perimeter of a rectangle is 2*(length + width). As given, the perimeter is 1000 feet, so we set up the equation: 1000 = 2*(w+100 + w).

Simplify this to get the width 'w' which is 200 feet and the length is 'w+100', so 300 feet.

The area of a rectangle is calculated by the formula length*width, therefore, calculating gives 200*300 = 60,000 square feet.

Final answer:

18 is 60% of 30, calculated by dividing 18 by 30 and then multiplying the result by 100.

Explanation:

Calculating the Percentage

To determine what percentage 18 is of 30, you can use the formula for calculating percentages:

Divide the number you want to find the percentage of (18 in this case) by the total number or 'whole' value (which is 30).

Multiply the result from step 1 by 100 to find the percentage.

So, the calculation is (18 ÷ 30) × 100, which equals 60%. Therefore, 18 is 60% of 30.

Final answer:

The expression equivalent to (6i)^3 is -216i, achieved by cubing the digit 6 to get 216 and remembering that i^3 is -i.

Explanation:

To find an expression equivalent to (6i)^3, we follow the rules of exponentiation and imaginary numbers. First, we cube the digit part, which is 6, to get 6^3 = 216. Next, we cube the imaginary unit i. Recall that i is the imaginary unit where i^2 = -1. Thus, i^3 is the same as i^2 multiplied by i, which equals to -i.

Combining these, we obtain (6i)^3 = 6^3 * i^3 = 216 * (-i) = -216i. This is the simplified form of the original expression.

Answer:

The amount which real estate agency gets is $  21,010  .

Step-by-step explanation:

Given as :

The selling price for a house = $ 382,000

The commission rate for real estate agency = 5.5 %

The commission rate for the agent = 30 %

So, the commission which real estate agency get = 5.5 % of $ 382,000

I.e the commission which real estate agency get = 0.055 × $ 382,000

Or, the commission which real estate agency get = $ 21,010

Again ,

The commission which agent get = 30 % of $ 382,000

I.e the commission which agent get = 0.3 × $ 382,000

Or, the commission which agent get = $ 114,600

Hence The amount which real estate agency gets is $  21,010  . answer

The agent earns a commission of $6,303 from the $382,000 house sale. This is calculated by first determining the real estate agency's commission of 5.5% on the sale price, which is $21,010. Then calculating 30% of this figure, which is the agent's earnings.

To calculate the total commission the agent will receive, you first have to calculate how much the real estate agency gets, and then calculate the agent's earnings based on that number.

The real estate agency's commission is 5.5% of the total sold price of the house. This can be calculated as:

(5.5 / 100) * $382,000 = $21,010

The agent then receives 30% of this amount, which you calculate as:

(30 / 100) * $21,010 = $6,303

Therefore, the agent earns a commission of $6,303 from the sale of the house.

Now, 44 ft arc length is equivalent to 360°  

Hence, 24.42 ft arc length is equivalent to [tex]\frac{360}{44} \times 24.42 = 199.8[/tex] degree.

Answer:

The line 2 and Line 3 are perpendicular to each others

But There is no relation between Line 1 and Line 2  , Line 1 and Line 3

Step-by-step explanation:

Given as :

The three line equation is

Line 1 : 2 y = 5 x + 6

Line 2 : y = [tex]\frac{2}{5}[/tex] x - 1

Line 3 : 10 x + 4 y = - 6

Now, The standard equation of line is

y = m x + c

where m is the slope of line

And c is the y intercept

So, From Line 1

2 y = 5 x + 6

or , y =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{6}{2}[/tex]

I.e y =  [tex]\frac{5}{2}[/tex] x + 3

So,  slope of this line = [tex]m_1[/tex] =  [tex]\frac{5}{2}[/tex]

Again , From Line 2

y = [tex]\frac{2}{5}[/tex] x - 1

So, slope of this line =  [tex]m_2[/tex] =  [tex]\frac{2}{5}[/tex]

Similarly , From Line 3

10 x + 4 y = - 6

I.e 4 y = - 6 - 10 x

or, y = - [tex]\frac{6}{4}[/tex] -  [tex]\frac{10}{4}[/tex] x

I.e y =  - [tex]\frac{5}{2}[/tex] x  - [tex]\frac{6}{4}[/tex]

So, Slope of this line = [tex]m_3[/tex] = - [tex]\frac{5}{2}[/tex]

Now, If the lines are parallel , then the slope of the lines are equal

And  If the lines are perpendicular , then the product of the slopes of the lines = - 1

Now, From given lines

[tex]m_2[/tex] × [tex]m_3[/tex] = [tex]\frac{2}{5}[/tex] × ( - [tex]\frac{5}{2}[/tex] )

I.e [tex]m_2[/tex] × [tex]m_3[/tex] = - 1

So, The line 2 and Line 3 are perpendicular to each others

But There is no relation between Line 1 and Line 2  , Line 1 and Line 3

Hence The line 2 and Line 3 are perpendicular to each others

Or

h=f/8g

To solve for the variable h in the formula f = 8gh, divide both sides of the equation by 8g. The formula for the variable h is h = f / (8g).

To solve the formula for the variable h, we need to isolate h on one side of the equation. In this case, the equation is f = 8gh. To isolate h, we divide both sides of the equation by 8g. This gives us:

h = f / (8g)
