Answer:

The percentage decrease in price of Air conditioner is 33.33%  

Step-by-step explanation:

Given as :

The initial price of air conditioner = Rs 27000

The reduce price of air conditioner = Rs 24000

Let the rate of percentage = x %

So,  % decrease = [tex]\frac{\textrm initial value - \textrm final value}{\textrm initial value}[/tex] × 100

Or,  % decrease = [tex]\frac{\textrm 27000 - \textrm 24000}{\textrm 27000}[/tex] × 100

Or , % decrease = [tex]\frac{3000}{27000}[/tex]  × 100

Or,  % decrease = [tex]\frac{100}{9}[/tex]

Or. % decrease = 33.33 %

Hence The percentage decrease in price of Air conditioner is 33.33%   Answer

Answer:

y = 2x

Step-by-step explanation:

Note the relationship between x and y, that is

x = - 42 → y = - 84 ← that is y = 2x

x = - 14 → y = - 28 ← that is y = 2x

x = 14 → y = 28 ← that is y = 2x

x = 42 → y = 84 ← that is y = 2x

Thus the linear equation is y = 2x

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the table we have the points (14, 28) and (42, 84).

Substitute:

[tex]m=\dfrac{84-28}{42-14}=\dfrac{56}{28}=2[/tex]

Put the val;ue of a slope and the coordinates of the point (14, 28) to the equation of a line:

[tex]28=2(14)+b[/tex]

[tex]28=28+b[/tex]    subtract 28 from both sides

[tex]28-28=28-28+b\\\\0=b\to b=0[/tex]

Finally we have:

[tex]y=2x+0=2x[/tex]

Answer:

The value of y for x = 8 is 60  .

Step-by-step explanation:

Given expression as :

For x = 2  , y = 15

Let the equation be written with constant k'

So, y = k x

Or, k = [tex]\dfrac{y}{x}[/tex]

∴   k =  [tex]\dfrac{15}{2}[/tex]

Now, again

For x = 8

equation can be written as

   y = k x

Or,  y =  [tex]\dfrac{15}{2}[/tex] × 8

Or,  y = [tex]\frac{15\times 8}{2}[/tex]

∴    y = 15 × 4

I.e  y = 60

Hence The value of y for x = 8 is 60  . Answer

Answer:

28 n 2 + 64 n + 16

Step-by-step explanation:

The sum of 5 consecutive odd integers is 145. These are the other 4 consecutive odd numbers. Now if we add all of these up we will get this : 25 + 27 + 29 + 31 + 33 = 145.

Hope I helped! ☺☼

The five consecutive odd numbers that sum up to 145 are 25, 27, 29, 31, and 33.

Let's call the middle of the five consecutive odd numbers n. Because these numbers are odd and consecutive, the two numbers before n will be n-2 and n-4, and the two after will be n+2 and n+4. The sum of these five numbers is:

n-4 + n-2 + n + n+2 + n+4 = 5n.

Since the sum of the five numbers is 145, we have:

5n = 145.

To find the value of n, we divide both sides by 5:

n = 145 / 5,

n = 29.

So the middle number is 29, and the five consecutive odd numbers are 25, 27, 29, 31, and 33.

The above question is incomplete, the complete question is:

The sum of 5 consecutive odd numbers is 145. find the numbers.

Answer:

x = - 3

Step-by-step explanation:

x = 8 is the equation of a vertical line parallel to the y- axis.

Thus a line parallel to it will also be vertical with equation

y = c

Where c is the value of the x- coordinates the line passes through

The line passes through (- 3, - 2) with x- coordinate - 3, thus

x = - 3 ← equation of parallel line

There is no equation of a line that is parallel to x=8 and passes through the point (-3, -2).

To find the equation of a line parallel to x = 8 and passing through the point (-3, -2), we need to know that a line with an equation x = a is a vertical line passing through the point (a, 0), and it has no slope. Since we need to find a line with the same slope as x = 8, we can set the equation to x = -3, which represents a vertical line passing through the point (-3, 0).

However, this line is parallel to x = 8 rather than passing through the point (-3, -2). Therefore, there is no equation of a line that is parallel to x = 8 and passes through the point (-3, -2).

Answer:

D

3. Reflexive Property of (Congruence) ≅

4. SSS (Side to Side to Side Congruence rule)

Step-by-step explanation:

3. Any geometric figure compared to itself is congruent to itself so this is why:

[tex]\overline{AC}\cong \overline{CA}\\\angle B\cong \angle B\\(...)[/tex]

4. Since we have a parallelogram, therefore we can say:

[tex]\overline{BC}\cong \overline{DA}\\\\\overline{BA}\cong \overline{DC}\\\\\overline{CA}\cong \overline{AC}\\[/tex]

Both triangles ABC and CDA satisfy the side to side to side congruence, since their 3 sides are congruent.

So, It's D.

Answer:

During January it decreased by $3,530.

Step-by-step explanation:

Given data:

Value of stocks in January 1st = $8,474

Value of stocks on March 1st = $3,323

Decrease value during February = $1,621

To find the decrease value during January.

Solution:

Let the decrease value in dollars during January be = [tex]x[/tex]

So, value of stocks in dollars on 1st February will be = [tex]8474-x[/tex]

So, value of stocks in dollars on 1st March will be = [tex]8474-x-1621[/tex]

So, we have

[tex]8474-x-1621=3323[/tex]

[tex]6853-x=3323[/tex]

Subtracting both sides by 6853.

[tex]6853-x-6853=3323-6853[/tex]

[tex]-x=-3530[/tex]

Multiplying both sides by -1.

∴ [tex]x=3530[/tex]

Thus, during January it decreased by $3,530.

Hey there! :)

Equation 1) -2x + y = 14

Equation 2) 4x - 6y = 4

Add 2x to both sides of equation 1 so that we can get the value of y.

y = 2x + 14

Now, plug the value of y into our second equation.

4x - 6(2x + 14) = 4

Simplify.

4x - 12x - 84 = 4

Add 84 to both sides.

4x - 12x = 4 + 84

Simplify.

-8x = 88

Divide both sides by -8.

x = -11

Now, plug our value of x into our first equation in order to find y.

-2x + y = 14

-2(-11) + y = 14

22 + y = 14

y = -8

Therefore, the systems of equation variables are : (-11, -8)

x=(240m*1/2t)/90m

x=120/90

x=4/3t

The construction crew can clear 8/3 tons of dirt in 4 hours.

To find out how much dirt the construction crew can clear in 4 hours, we need to first determine their rate of clearing dirt. The question states that they can clear 1/2 ton of dirt in 90 minutes. To calculate their rate, we divide the amount of dirt cleared (1/2 ton) by the time taken (90 minutes):

Rate = 1/2 ton / 90 minutes

Simplify the rate:

Rate = 1/2 × 2/90 ton/minute = 1/180 ton/minute

Now, to find how much dirt they can clear in 4 hours, we multiply their rate by the number of minutes in 4 hours:

Dirt cleared = Rate × Time

Dirt cleared = 1/180 ton/mintue × 4 hours × 60 minutes/hour

Simplify the units:

Dirt cleared = 1/180 × 4 × 60 ton

Calculate the result:

Dirt cleared = 8/3 ton

Therefore, the construction crew can clear 8/3 tons of dirt in 4 hours.

-82.5, -41 4/5, -13 1/8, -4.3

Final answer:

To arrange the numbers from least to greatest, you order them based on their value on the number line, with larger negative values representing smaller quantities. The numbers from least to greatest are -82.5, -41 4/5, -13 1/8, and -4.3.

Explanation:

To arrange the numbers -4.3, -82.5, -41 4/5 (which is -41.8), and -13 1/8 (which is -13.125) from least to greatest, we must compare their values on the number line. Larger negative numbers are those with the greater absolute value or those that are farther from zero in the negative direction.

Focusing on the given numbers:

-82.5 is the largest negative number, so it is the least.

-41 4/5 (or -41.8) is next, being less negative than -82.5.

-13 1/8 (or -13.125) is less negative than both -82.5 and -41.8.

-4.3 is the smallest negative number, so it is the greatest of the negatives.

Therefore, when ordered from least to greatest, the numbers are:

-82.5

-41 4/5

-13 1/8

Answer:

In descending order the function are represented as [tex]D>F>A>B>E>C[/tex]

Step-by-step explanation:

Whether it is increasing or is the larger or smaller number it all depends on its slope.

Equation of line [tex]y=m(x)+c[/tex],and [tex]m[/tex] is the slope.

So we will work with the slopes of each equations and arrange them in descending order.[Greater to larger number sequence]

Slopes are [tex]\frac{4}{3}, \frac{5}{4}, \frac{-2}{1},\frac{7}{4}, \frac{6}{5}, \frac{8}{5}[/tex]

We will equate the denominator by taking LCD of it then multiply numerator and denominator with a fix number which can bring all the denominator same.

LCD of the denominator [tex](1,3,4,5)=60[/tex]

Example:

[tex]\frac{4}{3}=\frac{4\times 20}{3\times 20}= \frac{80}{60}[/tex]

Similarly we will equate all the fractions.

So the slope are [tex]\frac{80}{60}, \frac{75}{60}, \frac{-120}{60},\frac{105}{60}, \frac{72}{60}, \frac{96}{60}[/tex]

In descending order the numbers are:

[tex]\frac{105}{60},\frac{96}{60}, \frac{80}{60}, \frac{75}{60},\frac{72}{60},\frac{-120}{60}[/tex]

According to the option the right choice are as follows:

[tex]D>F>A>B>E>C[/tex]

To find increasing functions, examine the slope of each equation, which must be positive for the function to be increasing. Functions A, B, D, E, and F are increasing, with D having the largest unit rate. C is a decreasing function and is not classified with the others.

To determine which functions are increasing, we look at the coefficient of x in each equation since that represents the slope of the line. For a function to be increasing, its slope (unit rate) must be positive. Comparing the slopes will help us classify each function as having a larger unit rate or a smaller unit rate than the function represented in the graph. Without the specific function from the graph for comparison, we'll just compare the given functions to each other.

Based on the slopes, D has the largest unit rate, followed by F, A, B, and E, in that order. Function C is not increasing and thus not part of this classification.
