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.

A point B is (1 , -9)

Step-by-step explanation:

The formula of the slope of a line is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

where [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are two points

lie on the line

We need to find a point B that makes that true

Assume that point B is (x , y)

∵ Point A = (5 , 3)

∵ Point B = (x , y)

∴ [tex]x_{1}=5[/tex] and [tex]x_{2}=x[/tex]

∴ [tex]y_{1}=3[/tex] and [tex]y_{2}=y[/tex]

- Substitute these values in the formula of m

∴ [tex]m=\frac{y-3}{x-5}[/tex]

∵ m(A , B) = 3

- Equate the formula of the slope by 3

∴ [tex]\frac{y-3}{x-5}=3[/tex]

- By using cross multiplication

∴ y - 3 = 3(x - 5)

- Simplify the right hand side

∴ y - 3 = 3x - 15

- Add 3 for both sides

∴ y = 3x - 12

To find point B chose any value for x and substitute it in the

equation to find y

∵ x = 1

∴ y = 3(1) - 12 = 3 - 12

∴ y = 9

∴ Point B = (1 , -9)

V.I.N: You can find many values of point B by chose different values of x and find the corresponding values of y

A point B is (1 , -9)

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

Answer:

$9.40

Step-by-step explanation:

well since you work 37.5 hours and you earn $352.50 you divide them to get your hourly wage

352.5 ÷ 37.5 = 9.4

so your hourly wage is $9.40

Final answer:

To calculate the hourly wage, the total earnings of $352.50 should be divided by the total work hours of 37.5. The hourly wage comes out to be $9.40.

Explanation:

To find out your hourly wage, you need to divide your total earnings by the number of work hours. In this instance, you worked 37.5 hours (since 1/2 an hour is equivalent to 0.5 hours) and earned $352.50. So, your hourly wage would be calculated as follows:

Hourly Wage = Total Earnings ÷ Number of Work Hours

Hourly Wage = $352.50 ÷ 37.5 hours

Hourly Wage = $9.40 per hour

Therefore, your hourly wage is $9.40.

Now, the circumference of the circle is given by the formula C = 2πr

So, [tex]C = 2 \times \frac{22}{7} \times 7 = 44[/tex] ft.

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.

Therefore, the central angle is 199.8° (Answer)

Answer:

The radius of the circle is 12.006 m.

Step-by-step explanation:

Let us assume the radius of the circle = r

Circumference  = 75.4 m

Now, CIRCUMFERENCE OF A CIRCLE = 2 π r

⇒ 75 .4 m = 2 π r

Now, putting  π = 3.14, we get:

75 .4 m = 2 (3.14)  r

⇒ 75.4 = 6. 28 r

or, r = 75.4/6.28 =  12.006

or, r  = 12.006 m

Hence, the radius of the circle with circumference 75.4 m is 12.006 m.

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.

4. 3/4 of the students in Mr. Ben's class do not have siblings in the same school.

5. There are 14 students with glasses and 7 without glasses.

Step-by-step explanation:

1. Let's review the information given to us for solving the questions:

Number of students in the school = 482

Ms. Ashley's Grade 4 class = 21 students

Ms. Ashley's Grade 4 class boys = 15 students

Ms. Ashley's Grade 4 class girls = 6 students

Ms. Ashley's Grade 4 class with glasses = 2/3 * 21 = 42/3 = 14 students

Mr. Ben's Grade 4 class = 24 students

Mr. Ben's Grade 4 class boys = 10 students

Mr. Ben's Grade 4 class girls = 14 students

Mr. Ben's Grade 4 class with siblings in the school = 1/4 * 24 = 24/4 = 6 students

2. Let's answer all the questions:

1. What fraction of the students in the school are in grade 4?

(Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)/ Number of students in the school

21 + 24 / 482 = 45/482

2. What fraction of the grade 4 students are boys?

(Ms. Ashley's Grade 4 boys + Mr. Ben's Grade 4 boys)/ (Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)

15 + 10 / 21 + 24

25 / 45 = 5/9

3. What fraction of the grade 4 students are in Ms. Ashley's class?

Ms. Ashley's Grade 4 class / (Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)

21 / 21 + 24

21 / 45 = 7/15

4. What fraction of the students in Mr. Ben's class that do not have siblings in the same school?

(Mr. Ben's Grade 4 class - Mr. Ben's Grade 4 class with siblings in the school)/ Mr. Ben's Grade 4 class

24 - 6 / 24

18 / 24 = 3/4

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.

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.
