Answer:

GH = 20

Step-by-step explanation:

Set each segment to a multiple of x: 6x, 4x, x

If you add up the line segments, you get 55

So:

6x + 4x + x = 55

11x = 55

x = 5

GH is 4x so 4*5 is 20

Answer:

It would increase by 1

Step-by-step explanation:

Step 1: Find the mean of the original

(9+6+1+1+3)/5 = 4

Step 2: Find the mean of the new

(9+6+1+1+8)/5 = 5

Step 3: Find the difference

5 - 4 = 1

Elimination<br>3x +2y=9<br>3x ty=0<br>1

muminat

Answer:

$y = 9$

$x = -3$

Step-by-step explanation:

Given

$3x + 2y = 9$

$3x + y = 0$

Required

Solve by elimination

To do this, we subtract both equations (to eliminate x)

$3x + 2y = 9$

- $3x + y = 0$

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

$3x - 3x + 2y - y = 9-0$

$y = 9$

Substitute $y = 9$ in $3x + y = 0$

$3x + 9 = 0$

Solve for 3x

$3x =- 9$

Solve for x

$x = -9/3$

$x = -3$

The sum of two consecutive terms in the arithmetic sequence 3, 6, 9, 12, ... is 303; find these two terms.

Nikolay [14]

1st consecutive term is x. 2nd consecutive term is (x + 3)
x + x + 3 = 303
2x + 3 = 303
2x = 303 - 3
2x = 300
x = 300/2
x = 150

x + 3 = 150 + 3 = 153

so ur 2 numbers are 150 and 153

The circle will be enlarged by a scale factor of 4.

sertanlavr [38]

Answer:

The area of the new circle is $144\pi \ in^2$

Step-by-step explanation:

Given:

radius of the circle = 3 in.

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared.

Let

z-----> the scale factor

x-----> the area of the enlarged circle

y-----> the area of the original circle

So;

$z^2= \frac{x}{y}$

In this problem we have

$z=4$ ----> the scale factor

The area of the original circle is equal to

$y = \pi r^2= \pi (3)^2= 9\pi \ in^2$

Now substituting value of y and solve for x we get;

$4^2=\frac{x}{9\pi}\\ \\x= 16\times9\pi= 144\pi \ in^2$

Hence Area of the new Circle is $144\pi \ in^2$

Also The area of the enlarged circle is 16 times the area of the original circle.
