The value of x is given from proportion and x = 9

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the first polygon and second polygon be similar

So , the ratio of their corresponding sides will also be similar

Substituting the values in the equation , we get

( x -1 ) / 6 = 16 / 12   be equation (1)

On simplifying the equation , we get

Multiply by 6 on both sides of the equation , we get

( x - 1 ) = ( 16 x 6 ) / 12

( x - 1 ) = 16 / 2

On simplifying the equation , we get

x - 1 = 8

Adding 1 on both sides of the equation , we get

x = 9

And ,

( y + 1 ) / 21 = 32 / 24   be equation (2)

On simplifying the equation , we get

Multiply by 21 on both sides of the equation , we get

( y + 1 ) = ( 4 x 21 ) / 3

y + 1 = 4 x 7

y + 1 = 28

Subtracting 1 on both sides of the equation , we get

y = 27

Hence , the value of x is 9

Step-by-step explanation:

Remark

The formula you use is (Electricity / Total Income ) * 100

The ratio becomes 53.7/1725  * 100%

The ratio is 53.7/1725 * 100 = 0.03113 * 100

The % = 0.03113 * 100 = 3.113

To the closest tenth that is 3.1%

Answer:

Thank to Goalscore24 correcting me, its actually Maria walking faster

Because 40 divided by 25 is 1.6

and 30 divided by 10 is 3

So Maria runs 3 miles in 1 second, and Luke runs 1.6 miles in 1 second

So Maria is faster.

Answer:

Step-by-step explanation:

The volume of a rectangular prism is

V=xyz, where x,y,z are the three dimensions, in this case

V=10(4.5)6.25

V=281.25 ft^3

Given:

The function is

[tex]f(x)=2x^3+kx-9[/tex]

The remainder when f(x) is divided by x−2 is 23.

To find:

The value of k.

Solution:

According to the remainder theorem, if a polynomial P(x) is divided by (x-c), then the remainder is P(c).

It is given that, the remainder when f(x) is divided by x−2 is 23. By using remainder theorem, we get

[tex]f(2)=23[/tex]       ...(i)

Put x=2, to find the value of f(2).

[tex]f(2)=2(2)^3+k(2)-9[/tex]

[tex]f(2)=2(8)+2k-9[/tex]

[tex]f(2)=16+2k-9[/tex]

[tex]f(2)=2k+7[/tex]          ...(ii)

Using (i) and (ii), we get

[tex]2k+7=23[/tex]

[tex]2k=23-7[/tex]

[tex]k=\dfrac{16}{2}[/tex]

[tex]k=8[/tex]

Therefore, the value of k is 8.

Answer:

30%

Step-by-step explanation:

Given data

Area of Home= 2,200 square feet

Area of wood flooring=  660 square feet

The percent of wood flooring in the house can be gotten as

Answer:

They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units

Step-by-step explanation:

Remember your y-intercept has an x value of zero, so line B has a y intercept of (0,-2)

now let's find b in the original equation so

y - 8 = -2x - 2 so y = -2x -2 + 8, so y = -2x + 6

So line A has a y-intercept of (0,6)

They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units

Answer:

1 and 7

Step-by-step explanation:

(x+4)(x-2) = x²+2x-8

set up proportion:

2x-3/ x²+2x-8 = 1/5

cross-multiply:

5(2x-3) = x²+2x-8

10x-15 = x²+2x-8

Combine Like Terms:

x²-8x+7

Factor:

(x-7)(x-1)

set each factor equal to zero and solve:  x = 1, x = 7

Answer:

[tex] \frac{(2x - 3)}{(x + 4)(x - 2)} = \frac{1}{5} \\ \frac{2x - 3}{x {}^{2} - 2x + 4x - 8} = \frac{1}{5} \\ x {}^{2} - 2x + 4x - 8 = 5(2x - 3) \\ x {}^{2} + 2x - 8 = 10x - 15 \\ x {}^{2} + 2x - 10x = - 15 + 8 \\ x { }^{2} - 8x = - 7 \\ x {}^{2} - 8x + 7 = 0 \\ x {}^{2} - x - 7x + 7 = 0 \\ x(x - 1) + 7(x - 1) \\ x + 7 = 0 \\ x = - 7or \\ x - 1 = 0 \\ x = 1[/tex]

Answer:

36(x + 1)^2 = 0 or 36x^2 + 72x + 36

Step-by-step explanation:

s^2 = area of a square

(6x + 6) (6x + 6)

6x*6x = 36x^2

6x*6 = 36x

6*6x = 36x

6*6 = 36

36x^2 + 36x + 36x + 36

36x^2 + 72x + 36

36(x + 1)^2 = 0
