Problem
The sum of 3 consecutive even numbers is 132.
What is the third number in this sequence?

Answer: Area=35km^2

Step-by-step explanation:

You need to find the areas of the rectangle and then the triangle.

First, you start with splitting up the figure to a rectangle and a triangle.

Secondly 6*5= 30 so the area of the rectangle is 30 km.

Thirdly, you add that to the area of the triangle, which you figure out because the opposite side of the figure is 6 km so the remaining length is going to be 2km. The area of a triangle is (1/2)(Base)(Height), so (1/2)(5)(2)= 5.

Add the 30 with the 5 and you get a total of 35 km for the area.

Answer:

i think the answer is 240km cuz you multiply 8x5x6. hope this helps, boo!

Step-by-step explanation:

Ngoc should predict that the home is located in Smavile based on the real estate advertisement

From the question, we have the following parameters that can be used in our computation:

Function 1: p = 150 + 0.041a (Smavile)

Function 2: p = 250 + 0.198a (Fancyville )

Where

a = area

p = price

From the question, we have

a = area = 2800

p = price = 280000

Using the above as a guide, we have the following:

So, we have

Function 1: p = 150 + 0.041 * 2800 (Smavile)

Evaluate the expression

p = 264.8 -- false

Function 2: p = 250 + 0.198 * 2800 (Fancyville )

Evaluate the expression

p = 804.4 --- false

264.8  is closer to 280 than 804.4

Hence, the home is in Smavile

The equation of the line passing through the points (0, -6) and (7, 4) in slope-intercept form is y = [tex]\frac{10}{7}[/tex]x - 6.

Slope of a line is defined as the tangent of the angle that the line makes with X axis.

Slope, usually denoted by 'm' of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by,

m = (y₂ - y₁) / (x₂ - x₁)

The equation of a line in slope-intercept form is y = mx + b, where b is y intercept and m is the slope.

Here, we have two points (0, -6) and (7, 4).

m = (4 - -6) / (7 - 0) = 10/7

y intercept is the y coordinate of the point where the line touches with the Y axis. x coordinate will be zero there.

We already have such point (0, -6).

So b = -6

Substituting these in slope-intercept form,

y =  [tex]\frac{10}{7}[/tex]x - 6

Hence, the equation of the given line in slope intercept form is y = [tex]\frac{10}{7}[/tex]x - 6.

Answer:

option 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = [tex]\frac{0-(-2)}{4-0}[/tex] = [tex]\frac{0+2}{4}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

constructing cones a right triangle whose hypotenuse is 23 m long is revolved about one of its legs to generate a right circular cone. radius: 11.5 m height: 23 m volume: 1650.6 m³

The hypotenuse of the triangle is 23 m. This means that the two sides are 11.5 m and 11.5 m. This gives us the radius of the cone.

The height of the cone is the same as the hypotenuse, so the height is 23 m.

The volume of a right circular cone can be calculated using the following formula: V = (πr²h)/3. In this case, the radius is 11.5 m, the height is 23 m, and π = 3.14. Plugging these values into the formula, we get a volume of 1650.6 m³.

V = (πr²h)/3

V = (3.14 × 11.5² × 23)/3

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units:  y=f(x+c) (same output, but c units earlier)

Right shift by c units:  y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the length of the line segment be = A

Now , the initial length of the line segment = 16 units

The line is reflected across the y-axis

So , when you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y)

And , the resulting line is translated 5 units down

But , the line segment does not change in dimension at all

So , the reflection and a translation does not affect the length of the line segment

Hence , the length of the line segment is 16 units

So, the correct option is option (B).

Mekala has MP3 player Jumble has 4 techno songs, 2 country songs, and 3 jazz songs on it.

firstly, we represent this songs in ratio format :

Now, the ratio of techno songs to country songs to jazz songs = 4 : 2 : 3

Let the total number of songs which is unknowns be" x". So,

Total number of techno songs = 4x

Total number of country songs = 2x

Total number of jazz songs = 3x

Total number of songs that Mekala plans to Listen = 270

Then, 4 x + 2 x + 3 x = 270

=> 9 x = 270

Dividing both sides by 9, we get

=> x = 30

So, Number of techno songs = 4 × 30

= 120

Number of country songs = 2×30 = 60

Number of jazz songs = 3 × 30 = 90

Therefore lifetime value is such that   the total lifetime of all batteries in a package exceeds that value for only 5% of all packages is 13.548 hours

In statistics, the standard deviation measures how widely distributed or how much a bunch of values can vary. While a big standard deviation shows that values are scattered throughout a wider range, a low standard deviation suggests that values are frequently close to the set's mean.

Here,

given that the  lifetime of a certain type of battery is normally distributed with mean value 13 hours and standard deviation 1 hour.

Sample size=n =9

Sample mean =X' N is(13,1/3)

If c is the lifetime value, then only 5% of all packages will have a total battery lifetime that is longer than that amount.

Then we have P(X>c) =0.05

Convert into Z score to get

P(x-13/(1/3) > z) = 0.05

z =1.645 from std normal distribution table

Hence x = 13 + 1.645/3

x=13.548

Therefore lifetime value is such that   the total lifetime of all batteries in a package exceeds that value for only 5% of all packages is 13.548 hours.

Unitary method is the process in which the value of single unit can be calculated from the value of multiple unit and the value of multiple unit can be calculated from the value of single unit. Sometimes Value of single unit can be less than the value of multiple unit. For example - The relation between the cost of a commodity and the quantity of the commodity

Sometimes Value of single unit can be more than the value of multiple unit. For example - The relation between the number of men and the number of days taken by those men to do a certain job.

Ratio is used to determine how much one quantity is bigger  as compared to another. The first part of the ratio is called antecedant and the second part of the ratio is called consequent.

Suppose there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage.

The value of the larger of the two numbers is 5.73.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Two numbers = M and N

M + N = 8 _____(1)

M = 8 - N _____(2)

MN = 13 _____(3)

Putting (2) in (3) we get,

(8 - N)N = 13

8N - N² = 13

N² - 8N + 13 = 0

This is in the form of ax² + bx + c = 0

a = 1, b = -8 and c = 13

Using the determinant we have,

N = -b ± √(b² - 4ac) / 2a

N = 8 ± √(64 - 52) / 2

N = 8 ± √12 / 2

N = 8 ± 2√3 / 2

N = 4 ± √3

N = 4 + √3 and N = 4 - √3

[√3 = 1.73]

N = 5.73

N = 2.27

Now,

When N = 5.73, M = 8 - 5.73 = 2.27

When N = 2.27, M = 8 - 2.27 = 5.73
