Answer:

The percent increase in the price of the car is 31.36%.

Step-by-step explanation:

Given:

A car dealer buys a luxury car for $65,200 and sells it for $85,650.  

Now, to find the percent increase in the price of the car.

Cost price of the luxury car = $65,200.

Sell price of the luxury car = $85,650.

So, the price of the car increased by:

Sell price of the luxury car - Cost price of the luxury car.

[tex]=\$85,650-\$65,200\\\\=\$20,450.[/tex]

Thus, the price of car increased by $20,450.

Now,to get the percent increase in the price of the car:

[tex]\frac{20450}{65200} \times 100[/tex]

[tex]=0.3136\times 100[/tex]

[tex]=31.36\%.[/tex]

Therefore, the percent increase in the price of the car is 31.36%.

Answer:

StartFraction pi Over 4 EndFraction times StartFraction 180 degrees Over pi EndFraction.

Step-by-step explanation:

We know the relation between radian and degree is that, π radians = 180°.

Then we have to calculate the degree that is equivalent to [tex]\frac{\pi }{4}[/tex] radians.

Now, using the unitary method, we can calculate the degree value.

Therefore, [tex]\frac{\pi }{4}[/tex] radians is equivalent to [tex]\frac{\pi }{4} \times \frac{180}{\pi } = \frac{180}{4} = 45 ^{\circ}[/tex].

So, it is StartFraction pi Over 4 EndFraction times StartFraction 180 degrees Over pi EndFraction. (Answer)

Answer:

The area of the orange ​band is 576 + 48x square inches

Step-by-step explanation:

Step 1: Area of the green square

The area of the green square =[tex]side^2[/tex]

The area of the green square  =  [tex]x^2[/tex] square inches

Step 2: Area of the orange square

The area of the orange square =[tex]side^2[/tex]

The side of the orange square  =  12+12 + x = 24 +x

Now the area of the orange square  =[tex](x+24)^2[/tex]

Step 3: The area of the orange ​band

Area of the orange ​band =  area of the orange square - area of the green square

Area of the orange ​band =   [tex](x+24)^2 - x^2[/tex]

expanding and solving the equation we get

[tex]x^2 + 24^2 +48x - x^2[/tex]

[tex]576 + 48 x[/tex] square inches

Final answer:

The area of the orange band surrounding the central green square on the rug is found by subtracting the area of the green square from the area of the entire rug. The formula for the area of the orange band is 48x + 576 square inches, where x represents the side length of the green square.

Explanation:

To find the area of the orange band on the rug, we need to calculate the area of the entire rug and subtract the area of the central green square. The width of the orange band is given to be 12 inches. Therefore, each side of the orange rug is increased by 2 times 12 inches (for both the left and the right side of the green square), making the total length of the rug's side x + 2(12) inches.

The area of the entire rug, which is a larger square, is[tex](x + 24)^2[/tex] square inches. The area of the central green square is [tex]x^2[/tex]square inches. To find the area of the orange band, we subtract the area of the green square from the area of the entire rug which is: [tex](x + 24)^2 - x^2[/tex].

Expanding the squared term we get: [tex]x^2 + 48x + 576 - x^2[/tex], which simplifies to 48x + 576 square inches. That's the area of the orange band surrounding the green square.

Answer:

40X^3 - 34X^2 + 4X + 15

Step-by-step explanation:

Using Algebraic expansion, the first number in bracket with its coefficience multiplies the second bracket. Equally , the second number in the first bracket is also used to multiply the second bracket, taking note of the sign (addition and minus sign)

5x(8x^2 -2x +5) +3 (8x^2 -2x +5)

= 40X3 - 10X^2 + 10X -24X^2 - 6X + 15

= 40X^3 - 34X^2 + 4X + 15

After evaluating the expression with the given values for x, y, and z by following the order of operations, the final result of the expression is 28.

To evaluate the expression given x=4, y=9, and z=7, we follow the order of operations, which means we perform the operations inside the parentheses first before multiplying by x.

First, calculate the value inside the parentheses as follows:

y + z - 3 squared

= 9 + 7 - 32

= 9 + 7 - 9

= 16 - 9

= 7

Now, multiply this result by x:

x(y + z - 3 squared)

= 4(7)

= 28

So, the evaluated expression equals 28.

Answer:

The scale factor is 3.

Step-by-step explanation:

Let the origin O(0,0) is the reference point and the coordinates of the point A are given by (3,-6).

Therefore, the distance OA is given by [tex]\sqrt{(3 - 0)^{2} + (- 6 - 0)^{2}} = 3\sqrt{5}[/tex] units.

Again, the coordinates of point A' are (1,-2).

Therefore, the distance OA' is given by [tex]\sqrt{(1 - 0)^{2} + (- 2 - 0)^{2}} = \sqrt{5}[/tex] units.

Hence, the scale factor is [tex]\frac{OA}{OA'} = \frac{3\sqrt{5} }{\sqrt{5}} = 3[/tex]. (Answer)

Step-by-step explanation:

Given,

The product of two numbers = a

To find, the both numbers = ?

Let the two numbers = x

∴ x × x = a

⇒ [tex]x^{2}[/tex] =  a

⇒ [tex]x^{2} =\sqrt{a}^2[/tex]

Comparing the powers, we get

⇒ x = [tex]\sqrt{a}[/tex]

∴ First number = [tex]\sqrt{a}[/tex] and Second number = [tex]\sqrt{a}[/tex]

Thus, the product of two numbers is a,  [tex]\sqrt{a}[/tex] of both numbers.

The proportion that could be used to solve for the variable is [tex]\frac{16}{40}=\frac{3}{h}[/tex] ; h = 7.5 ⇒ answer b

Step-by-step explanation:

A proportional relationship: one variable is always a constant value times the other, that constant is called the constant of proportionality

The number of walls and the number of hours are increased or decreased together

∴ The number of walls and the number of hours are proportion

∵ 16 walls in 40 hours

∵ 3 walls in h hours

- By using the second rule above

∴ [tex]\frac{16}{40}=\frac{3}{h}[/tex]

The proportion that could be used to solve for the variable is  [tex]\frac{16}{40}=\frac{3}{h}[/tex]

Let us solve it to find h

∵  [tex]\frac{16}{40}=\frac{3}{h}[/tex]

- By using cross multiplication

∴ 16 × h = 3 × 40

∴ 16 h = 120

- Divide both sides by 16

∴ h = 7.5

The value of h is 7.5 hours

For a.

Since there are already two angles given for the triangle, we can measure the last angle using this formula:

90 + 55 + a = 180

Now solve for "a".

90 + 55 + a = 180

145 + a = 180

a = 180 - 145

a = 35°

For b.

From the picture above, the two triangle's tip are touching and having to form vertical angles. This means that the angles are congruent to each other.

Now that we have two angles in the second triangle(35 and 120), we can use the same formula:

35 + 120 + b = 180

Now solve for "b":

35 + 120 + b = 180

155 + b = 180

b = 180 - 155

b = 25°

Answer:

a = 35     b = 25

Step-by-step explanation:

Triangles always add up to 180 degrees.  Knowing this we can first solve the triangle with the right angle.

55 + 90 + a = 180

Before we solve this, keep in mind that the reflective property will be used on angle a, giving the answer to the third angle in the second triangle.

145 + a = 180

-145        -145

a = 35

Now that we have a solved use the reflective property to get it on the second triangle.

120 + 35 + b = 180

155 + b = 180

-155        -155

b = 25

There you have your two angles.

Hope this helped you out.

Answer: Angle X = 30

Step-by-step explanation: First and foremost, we should recognize that an isosceles triangle has two sides equal and the two angles subtended by the two equal sides are also equal in measurement.

This means. In the diagram on the left, line DE = line DF and that is 10cm.

The similar angles are the ones subtended by the lines identified as being equal, that is

Angle E = angle F and that is 75. If both angles measure a combined total of 150 the third angle can be derived simply as

180 - (75+ 75)

{Sum of angles in a triangle = 180}

180 - (150)

= 30

Therefore angle D = 30.

However having been given in the question that both triangles are similar and are isosceles, then

Angle D = Angle X and that is 30
