Answer 1

Answer:

x = 9

Step-by-step explanation:

(3x-20)/9 = 56/72

72(3x-20) = 9(56)

216x-1440 = 504

add 1440 to each side

216x = 1944

divide both sides by 216

x = 9

Answer 2

Answer:

9

Step-by-step explanation:

If you draw a segment parallel to a side of triangle that intersects two sides of the triangle, that segment divides the intersected sides into segments of proportional lengths.

9/72 = (3x - 20)/56

1/8 = (3x - 20)/56

3x - 20 = 1/8 * 56

3x - 20 = 7

3x = 27

x = 9

Answer: 9

Which graph shows a dilation?

Answers

Answer:

there is no picture..

Step-by-step explanation:

The first graph shows a dilation.

Option A is the correct answer.

What is dilation?

Dilation is a transformation that changes the size of an object without changing its shape.

It involves scaling an object by a factor called the scale factor.

We have,

First graph:

The initial shape is a rectangle.

The dilated shape is also a rectangle.

So it is a dilation.

Second graph:

The initial shape is a square.

The dilated shape is a rectangle.

So it is not a dilation

Third graph:

The initial shape is a rectangle.

The dilated shape is also a rectangle but the size is not dilated in similar dimensions.

So it is not a dilation.

Thus,

The first graph shows a dilation.

A concert venue has 20 seats in the first row and an 5 additional seats in each successive row. If there are 35 rows of seats then how many people can attend a sold-out show? 3,675 190 2,100

Answers

3,675 people

Step-by-step explanation:

First row, a = 20

Common difference, d = 5

number of terms, n = 35

Sn = n/2 {2a + (n - 1)d}

= 35/2 {2*20 + (35 - 1)5}

= 35/2 {40 + ( 34)5}

= 17.5(40 + 170)

= 17.5(210)

= 3,675 people

The answer is actually 3675.

Answers

Answer:

y = 3[tex]\sqrt{7}[/tex]

Step-by-step explanation:

The 2 right triangles inside the right triangle are similar, then ratios of corresponding sides are equal, that is

[tex]\frac{y}{9}[/tex] = [tex]\frac{7}{y}[/tex] ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = [tex]\sqrt{63}[/tex] = 3[tex]\sqrt{7}[/tex]
