Answer:

Cost of the first house : $480,000

Cost of the second house : $320,000

Step-by-step explanation:

An estate agent has three houses for sale. The prices of the houses were

in the ratio 6:4:3 and the cheapest house was priced at $240 000. What

were the prices of the other two houses? (SHOW WORKING)​

The prices of the house has a ratio of

6:4:3

Sum total = 6 + 4 + 3 = 13

Cheapest house = $240,000

The sum total cost of the 3 houses = x

x is calculated as:

= 3/13 × x =$ 240,000

= 3x = $240,000 × 13

x = $240,000 × 13/3

x = $1,040,000

The Cost of the first house =

6/13 × $1,040,000

= $480,000

Cost of the second house

= 4/13 × $1,040,000

=$320,000

Therefore,

Cost of the first house : $480,000

Cost of the second house : $320,000

Answer:

40 inches

Step-by-step explanation:

Similar Triangles

In similar triangles, corresponding sides are always in the same ratio.

Let x be the length of the missing side.

Therefore:

\(\implies \sf x:16=30:12\)

\(\implies \sf \dfrac{x}{16}=\dfrac{30}{12}\)

\(\implies \sf 16 \cdot \dfrac{x}{16}=16 \cdot \dfrac{30}{12}\)

\(\implies \sf x=\dfrac{480}{12}\)

\(\implies \sf x=\dfrac{40 \cdot 12}{12}\)

\(\implies \sf x=40\)

Therefore, the length of the missing side is 40 inches.

An equation of the plane passing through the points (3, 7, −7), (3, −7, 7), (−3, −7, −7) is x + y − z = 3.

Given points are (3, 7, −7), (3, −7, 7), and (−3, −7, −7).

Let the plane passing through these points be ax + by + cz = d. Then, three planes can be obtained.

For the given points, we get the following equations:3a + 7b − 7c = d ...(1)3a − 7b + 7c = d ...(2)−3a − 7b − 7c = d ...(3)Equations (1) and (2) represent the same plane as they have the same normal vector.

Substitute d = 3a in equation (3) to get −3a − 7b − 7c = 3a. This simplifies to −6a − 7b − 7c = 0 or 6a + 7b + 7c = 0 or 2(3a) + 7b + 7c = 0. Divide both sides by 2 to get the equation of the plane passing through the points as x + y − z = 3.

Summary: The equation of the plane passing through the given points (3, 7, −7), (3, −7, 7), and (−3, −7, −7) is x + y − z = 3.

Based on the given data, the probability of rolling a 4 on the next roll of this die is 0.3 or 30%.

It is used to predict and estimate the likelihood of future events and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

The probability of rolling next is a 4:

The total number of times the die was rolled is:

⇒ 8 + 4 + 3 + 9 + 2 + 4 = 30

The number of times the die landed on 4 is 9.

Then, the probability of rolling next a 4 is:

⇒ 9/30 = 3/10

⇒ 9/30 = 0.3

Therefore, based on the given data, the probability of rolling a 4 on the next roll of this die is 0.3 or 30%.

Answer:

D. The trinomial is equivalent to (x+2)(x-1)

Step-by-step explanation:

1. Factor out the common term x:

= x(x^2+x-2)

2. Factor the equation:

= x(x - 1)(x + 2)

From this, we can see that because the equation was factorable, it is not prime. Option B is not completely factored, so it is incorrect. The final ordered pair shown in Option C is has (x + 1), when it should be (x - 1), so it is also incorrect. Option D is the true statement.

Answer:

B.

Step-by-step explanation:

The quickest and most fool-proof way to do this is to using a graphing calc to graph the given equations. When you do so, you should see that B is the right choice. You can also tell from the asymptotes. x cannot equal 1 or -1, so B.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (11 - 10)/(6 - 5)

Slope (m) = 1/1

Slope (m) = 1

At data point (5, 10) and a slope of 1, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 10 = 1(x - 5)  

y = x - 5 + 10

y = x + 5 ≡ w = c + 5

The value of x is 3, while the length of the rectangle is 30 units and the width is 24 units.

The given parameters are:

Base = 5(x+3)

Height = 2(x+9)

Perimeter = 108

The perimeter of a rectangle is

P = 2 *(Base + Height)

So, we have:

2 *(5(x + 3) + 2(x + 9)) = 108

Divide both sides by 2

5(x + 3) + 2(x + 9) = 54

Open the brackets

5x + 15 + 2x + 18 = 54

Evaluate the like terms

7x = 21

Divide by 7

x = 3

Substitute x = 3 in Base = 5(x+3) and Height = 2(x+9)

Base = 5(3+3) = 30

Height = 2(3+9) = 24

Hence, the value of x is 3, while the length of the rectangle is 30 units and the width is 24 units.

Step-by-step explanation:

The value of the expression, (2x − 12) + (1/2xy-10), for x = 8 and y = 2 will be 2.

According to the question,

We have the following expression:

(2x − 12) + (1/2xy-10)

Now, the values of x and y are given to be 8 and 2 respectively.

So, we will put these values of x and y in the given expression:

(2*8-12)+(1/2*8*2-10)

First, we will use multiplication:

(16-12)+(8-10)

4+(-2)

(Note that when two integers are of different signs then the integers are subtracted but the sign in the result is of the larger integer.)

The function g(x) is a transformation of the parent function f(x) it was transformed to make g(x) - Horizontal or vertical stretch.

Let's start thinking about vertical stretching and compression by simply looking at the graphs rather than starting with a ton of math.

Vertical stretching is the process of making a function taller by stretching it out vertically.

Vertical compression entails squashing the function down vertically, making it shorter.

Stretching and compression genuinely appear like that. It's time to start doing some math to figure out how to modify the function so that the graph can be stretched or compressed.

When the function that generated the original graph is changed in a way that necessitates a smaller x-value in order to get the same y-value, this is known as horizontal compression.

This happens when a constant c with a value larger than 1 is multiplied by the x-value of a function.

Hence, The function g(x) is a transformation of the parent function f(x) it was transformed to make g(x) - Horizontal or vertical stretch.
