Answer:

5000 rupees

Step-by-step explanation:

Given the following :

Dimension of room = 5m × 2.5m

Cost of granite = 600 rupees per square meter

Cost of marble = 1000 rupees per square meter

Additional cost of using marble instead of granite :

Area of room = Area of rectangle = Length * width

Area of room = 5m × 2.5m = 12.5m^2

Cost of using granite:

Area of room × cost of granite per square meter

12.5 × 600 = 7500 rupees

Cost of using marble:

Area of room × cost of marble per square meter

12.5 × 1000 = 12,500 rupees

Difference in cost :

(12500 - 7500) rupees = 5000 rupees

Additional cost incurred if marble is used = 5000 rupees

Answer:

Original Area : 48 square inches

Step-by-step explanation:

Let's say that the width of this rectangle is x, and the length of this rectangular is y. Remember that they are even consecutive integers as well, so let's make the length 2 greater than the width.

x = width,

x + 2 = length

And remember that the width decreases by 3 inches, to result in a rectangle of area 24. So the width will be x - 3, and the area will be (x - 3)(x + 2). Therefore we have the quadratic equation (x - 3)(x + 2) = 24, in which we can solve for x and y to determine the area of the original rectangle.

Step # 1 : Expand the expression (x - 3)(x + 2),

x² - x - 6 = 24

Step # 2 : Simplify and factor the expression x² - x - 6

x² - x - 30 = 0 ⇒ (x + 5)(x - 6) = 0

Step # 3 : Apply the Zero Factor Principle

x + 5 = 0, and x - 6 = 0

x = - 5, x = 6

Now remember that the width can't be negative, so it will be 6 inches long. That would make the length 6 + 2 = 8 inches. The area of the original rectangular will be 6 [tex]*[/tex] 8 = 48 square inches.

Answer:

  48 square units

Step-by-step explanation:

Let L and W represent the length and width of the rectangle.

  L = W +2 . . . . . . assuming the length is more than the width

  L(W -3) = 24 . . . . the area after the reduction in width

__

  (W +2)(W -3) = 24

So, we're looking for factors of 24 that differ by 5. We know that 24=8·3, so we have ...

  W+2 = 8

  W = 6 . . . . . . . matches W-3=3, also

Then the length is ...

  L = W+2 = 8

and the area of the original rectangle is ...

  A = LW = (8 inches)(6 inches) = 48 square inches

So he makes 14 points per 8 minutes, and you need to find how many points he scores in 21 minutes.

[tex]\frac{8}{14} = \frac{21}{x}[/tex]

To get from 8 to 21, you have to multiply by 2.625

So do the same thing to the denominator; 14 × 2.625 = 36.75

Since 0.75 point is no point so you round down.

Jack scores 36 points in 21 minutes.

Answer:

x =36.75 points or approximately 37 points

Step-by-step explanation:

We can use a ratio to solve

8 minutes         21 minutes

----------------- = ----------------

14 points            x points

Using cross products

8x = 14*21

8x =294

Divide by 8

8x/8 = 294/8

x =36.75 points or approximately 37 points

Answer:

Asistieron 252 personas

Se recaudó una cantidad de $ 32760.

252 people attended the show.

$ 32760 amount was raised.

Step-by-step explanation:

Spanish

Número total de entradas = 255

Costo de un boleto = $ 130

Costo total = Número total de boletos * Costo de 1 boleto

          = 255 * 130 = $ 33150

Entonces se devolvieron 5 boletos y se vendieron dos más. La cantidad devuelta fue (5-2) * 130 = $ 390

Restando $ 390 de $ 33150 da $ 32760.

Asistieron 252 personas.

Como

255-5 + 2 = 252

y

Se recaudó una cantidad de $ 32760.

Esto también se puede resolver multiplicando = $ 130 * 252 = $ 32760

English

Total number of tickets = 255

Cost of one ticket = $ 130

Total Cost = Total Number of tickets * Cost of 1 ticket

          = 255 * 130= $ 33150

So 5 ticket was returned and two more were sold. The amount returned was (5-2) * 130= $ 390

Deducting $ 390 from $ 33150  gives $ 32760.

252 people attended the show.

As

255-5 + 2= 252

and

$ 32760 amount was raised.

This can also be solved by multiplying=  $ 130 *252= $ 32760

angle BCG=180-90-12=180-78=102

X=(108-102)/2=39

Answer:39°

Step-by-step explanation:

If you know some properties of circle you may solve it like this:

Since ∠CDF = 90°, FC is the diameter of the circle passing through C, D and F.

So B is the centre of the circle mentioned above as B is the mid-point of FC.

Then we have BF = BC = BD since they are all radii of the same circle.

∠BDF = ∠BFD = 12°

∠BDA = 90° + 12° = 102°

∠BDA + ∠BAD + ∠ABD = 180°

102° + x + x = 180°

x = (180° - 102°)/2 = 39°

Answer:

The correct option;

136 cubic inches

Step-by-step explanation:

The dimension of the rectangular flour canister are;

Length = 5 1/2 inches (5.5 inches)

Width = 4 inches

Height = 10 inches

The dimensions of the smaller sugar canister

Length = 3 1/2 inches (3.5 inches)

Width = 3 inches

Height = 8 inches

The volume of a cube is given by the relation;

V = Length × Width × Height

Therefore, we have;

The volume of the rectangular flour canister  = 5 1/2 × 4 × 10 = 220 in³

The volume of the rectangular sugar canister  = 3 1/2 × 3 × 8 = 84 in³

The difference in volume between the two canisters = 220 in³ - 84 in³ = 136 in³

The difference in volume between the two canisters = 136 in³

Answer:  see proof below

Step-by-step explanation:

Use the Double Angle Identity: sin 2Ф = 2sinФ · cosФ

Use the Sum/Difference Identities:

sin(α + β) = sinα · cosβ + cosα · sinβ

cos(α - β) = cosα · cosβ + sinα · sinβ

Use the Unit circle to evaluate: sin45 = cos45 = √2/2

Use the Double Angle Identities:   sin2Ф = 2sinФ · cosФ

Use the Pythagorean Identity: cos²Ф + sin²Ф = 1

Proof LHS → RHS

LHS:                                  2sin(45 + 2A) · cos(45 - 2A)

Sum/Difference: 2 (sin45·cos2A + cos45·sin2A) (cos45·cos2A + sin45·sin2A)

Unit Circle:    2[(√2/2)cos2A + (√2/2)sin2A][(√2/2)cos2A +(√2/2)·sin2A)]  

Expand:        2[(1/2)cos²2A  + cos2A·sin2A + (1/2)sin²2A]

Distribute:              cos²2A   + 2cos2A·sin2A + sin²2A  

Pythagorean Identity:    1 + 2cos2A·sin2A

Double Angle:                1 + sin4A

LHS = RHS:  1 + sin4A = 1 + sin4A   [tex]\checkmark[/tex]

Answer: [tex]x = \frac{\pi}{4} \ \text{radians}, \ \ y = \frac{\sqrt{2}}{2}[/tex]

Note: pi/4 radians is equal to 45 degrees

===========================================

To get this answer, you can use the unit circle to see that at 45 degrees or pi/4 radians, the sine and cosine value are both [tex]\frac{\sqrt{2}}{2}[/tex]

You could also use your calculator to graph y = sin(x)-cos(x) to find the x intercept in the interval [tex]0 < x < \frac{\pi}{2}[/tex] to find the approximate x intercept to be x = 0.70710678

Then note how [tex]\frac{\sqrt{2}}{2} \approx 0.70710678[/tex]

-----------------------------

Or you could do the following steps

sin(x) = cos(x)

sin^2(x) = cos^2(x)

sin^2(x) = 1 - sin^2(x)

sin^2(x) + sin^2(x) = 1

2sin^2(x) = 1

sin^2(x) = 1/2

sin(x) = sqrt(1/2)

sin(x) = sqrt(2)/2

Again you'll have to turn to the unit circle, or some reference sheet, to determine the x value that makes the last equation above to be true. That x value is x = pi/4 radians.

Answer:

Definition and Equation

This form of the equation of a line is called the slope-intercept form. The y-intercept of a line (b), is the y-coordinate of the point where the graph of the line crosses the y-axis. As we have seen in the Wild About Cupcakes example, it is the value of y when x = 0.

Hope it helped u if yes mark me BRAINLIEST!

Tysm!

:)

Answer: Hi!

Slope - intercept form is a type of equation (or formula.) It shows you how to graph a line and find the slope and y - intercept of that line.

Slope - intercept form looks like this: y = mx + b

M represents the slope of the line. B represents the y - intercept.

The y - intercept is where the line would intercept the y - axis. The slope is kind of like the angle the line is at (For example: it slopes downward.)

The height Abby climb above their original starting position is 20 feet.

Suppose the considered function whose graph is to be made is

f=f(x) f(x)

The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values

f=f(x) f(x)

are plotted on the vertical axis.

They are together plotted on the point

f(x)) (x,y) = (x, f(x))

This is why we usually write the functions as:

f(x) y = f(x)

We are given that;

Time= 12min

Now,

To find how high Abby climbed above their original starting position, we need to look at the graph and find the highest point of Abby’s climb.

We can see that Abby’s climb is represented by the blue line on the graph.

The highest point of Abby’s climb is at (6, 22), which means that after 6 minutes, Abby reached a height of 22 feet.

Since the original starting position is at (0, 2), which means that at the beginning, Abby was at a height of 2 feet, we can subtract 2 from 22 to find how high Abby climbed above their original starting position.

Abby climbed 22 - 2 = 20 feet above their original starting position.

Therefore, by the graph the answer will be 20 feet.
