Answer:

x=180

Step-by-step explanation:

The triangles are similar by AA, They both have a right angle and vertical angles are congruent.

[tex]\cfrac{90}{135} =\cfrac{120}{x} \\\\\cfrac{2}{3} =\cfrac{120}{x} \\\\2x*3(120)\\\\x=\cfrac{3(120)}{2} \\\\x=180[/tex]

Answer:

33 percent

Step-by-step explanation:

Let's see what we have here.

A shopkeeper sold Item X for a his selling price (SP).

Let SP = x

Since the question says that

Profit is 25% of the selling price,

we have: Profit = 25% SP = 0.25x

Now, we already know that:

Profit = SP - Cost

This part is the catch.

To find out how much Item X originally cost,

Cost = SP - Profit = x - 0.25x = 0.75x

Now that we know the original cost of Item X,

we can easily calculate the

Real profit % using this formula:=

(Profit/Cost)*100=

(0.25x/0.75x)*100= 33%

Answer: C

Step-by-step explanation:

to get the equation of any straight line, we simply need two points off of it, let's use the ones in the picture below.

[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{9})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{13}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{13}-\stackrel{y1}{9}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{1}}}\implies \cfrac{4}{2}\implies 2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{9}=\stackrel{m}{2}(x-\stackrel{x_1}{1}) \\\\\\ y-9=2x-2\implies y=2x+7[/tex]

it would be $2400

Step-by-step explanation:

1) if the point A(7;2) and the given line is in slope-interception form, then the  required parallel line has the same slope, its equation can be written as: y=-9x+C, where C - unknown number;

2) to calculate the C it is needed to substitute the A(7;2) into the required equation of the parallel line:

2=-9*7+C; ⇒ C=65.

3) the parallel line is: y=-9x+65.

4) if the point A(7;2) and the given line is in slope-interception form, then the slope of the perpendicular line is: (-1)/(-9)=1/9, and the required equation of the perpendicular line can be written as:

y=1/9 *x+C, where C - unknown number;

5) to calculate the C it is enough to substitute the A(7;2) into the required equation of the parallel line:

2=1/9 *7+C; ⇒ C=11/9;

6) the perpendicular line is:

[tex]y=\frac{1}{9} x+\frac{11}{9}.[/tex]

Answer:

Area = 99cm^2

Step-by-step explanation:

Seen cardboard = Total cardboard - picture

Total cardboard = 18 * 13

Total cardboard = 234

Picture = 15 * 9

Picture = 135

Seen cardboard = 234 - 135

Seen cardboard = 99

Answer:

99

Step-by-step explanation:

15x9=135

135 cm

18x13=234

234 cm

234-135=99

=99

Answer:

the numerator is 31 and the bottom is 8

Step-by-step explanation:

Answer: The slope is -3

and the y-intercept is 2

Step-by-step explanation:

Since this is in slope-intercept form, we can easily find the slope and the y-intercept.

The form for slope-intercept form is: y = mx + b

where m is the slope and b is the y-intercept.

Therefore, -3 is the slope and 2 is the y-intercept.

Search up slope-intercept form on the internet for more details.

Answer:

p is equal to 8.125

Step-by-step explanation:

Direct proportion formula : Y = kx ,k is constant

p = x = 3.2

r = y = 4

4 = k * 3.2

k = 4/3.2 = 1.25

y = 1.25x

Now, substitute x = 6.5 and find y.

y = 1.25 * 6.5 = 8.125

Hence p is equal to 8.125

Answer:

y= 7- 1/2.72x

Step-by-step explanation:

1. Graph your coordinates

2. Point down your y-intercept

3. Look for your slope

Note: the x of the equation doesn't have to be an exact answer

The equation of the line that passes through two points (3, 6) and (8, 4) is y = (-2/5)x + (36/5).

The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of a line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Here:

(x₁, y₁) = (3, 6) and (x₂, y₂) = (8, 4)

m = (4 - 6) / (8 - 3) = -2 / 5

Now we can choose either point and plug in the values for x₁, y₁, and m to get the equation of the line:

y - y₁ = m(x - x₁)

y - 6 = (-2/5)(x - 3)

Simplifying the equation, we can write it in slope-intercept form:

y = (-2/5)x + (36/5)

Therefore, the equation is y = (-2/5)x + (36/5).

Answer:

y=4/3x+4

Step-by-step explanation:

y-y1=m(x-x1)

y-(-8)=4/3(x-(-9))

y+8=4/3(x+9)

y=4/3x+36/3-8

y=4/3x+12-8

y=4/3x+4

Answer:

The second one from the top (f(X)2)

Solution:

If a triangle is translated 4 units left and 2 units up, it means that the coordinates of A, B, and C will move 4 units left and 2 units up.

We know that:

Translating the coordinate 2 units up and 4 units left.

If we put them together, we get A(-4, 3) B(-3, -1) C(0, 1).

New coordinate after transforming  4 units left and 2 units up will be A'(-4, 3) , B'(-3, -1) and C'(0, 1).

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given coordinates are

A(0, 1) B(1, -3) and  C(4, -1)

By transforming 4 units left and 2 units up

New coordinates will be

A(0 - 4, 1 + 2) ⇒  A'(-4, 3)

B(1 - 4, -3 + 2) ⇒ B'(-3, -1)

C(4 - 4, -1 + 2) ⇒ C'(0, 1)

Hence " New coordinate will be A'(-4, 3) , B'(-3, -1) and C'(0, 1)".

Answer:

120 cubic feet

Step-by-step explanation:

volume is length times width times height

since the base numbers are the same you can add 24+ 96 = 120 or

24 ÷ 3 = 8

96 ÷ 3 = 32

8 + 32 = 40 × LWH 3 = 120

d + (-7)

i don't know if this is what you mean

A shape is similar if corresponding angles are equal & if one is an enlargement of the other.

(I. E., one shape is twice as big as the other one.)

So, compare the lengths to find a common scale factor (of 2, for example, where you multiple by 2 to get a value & divide to get original value, from one shape to another.)
