Answer:

  x = √70

Step-by-step explanation:

The right triangles are all similar, so we can write the ratio of long side to hypotenuse as ...

  x/(7+3) = 7/x

  x^2 = 7(10) = 70

  x = √70

_____

Additional comments

This is called a "geometric mean", where x is the square root of the product of two numbers, 7 and 10. Those happen to be the lengths of the adjacent segment of the hypotenuse and the whole hypotenuse.

The same relation holds for BC:

  BC = √(CD·CA)

__

A slightly different geometric mean relation holds for the altitude BD:

  BD = √(DC·DA)

Answer:

28 8/21

Step-by-step explanation:

18 5/7 + 9 2/3 (hint: remember you have to turn them into common denominators)

so ther least common denominator would be 21 so...

18 15/21 + 9 14/21

then add it together

28 8/21

Answer:

I got 28 8/21. There's a picture of how I did it.

Step-by-step explanation:

I used a method called the butterfly method. I did 18 + 9 which equals 27. Then I did 5/7 + 2/3 and got 29/21, and divided the fraction and got 28 8/21.

Answer:

RS = 47 units

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

3x + 5 = [tex]\frac{1}{2}[/tex] ( 2x + 15 + 6x - 37)

3x + 5 = [tex]\frac{1}{2}[/tex] (8x - 22) = 4x - 11 ( subtract 4x from both sides )

- x + 5 = - 11 ( subtract 5 from both sides )

- x = - 16 ( multiply both sides by - 1 )

x = 16

Thus

RS = 2x + 15 = 2(16) + 15 = 32 + 15 = 47

what value of x makes this statement true?
3x=2x+12

A) 2
B) 5
C) 6
D) 12

Answers

Answer:

The value of x = 12, makes the statement [tex]3x=2x+12[/tex]  true

Option D is correct option.

Step-by-step explanation:

What value of x makes this statement true?

[tex]3x=2x+12[/tex]

We need to solve the equation to find value of x

[tex]3x=2x+12[/tex]

Subtract 2x on both sides

[tex]3x-2x=2x+12-2x\\x=12[/tex]

So, the value of x is: x=12

So, The value of x = 12, makes the statement [tex]3x=2x+12[/tex]  true

Option D is correct option.

Mr. JB has a rectangular lot that measures 550 meters by 550 km. What is the area of the land in square meter. He i selling the whole lot for 206,250,000 pesos how much is the price per square meter?

Answers

9514 1404 393

Answer:

  15/22 peso/m^2 ≈ 0.68182 peso/m^2

Step-by-step explanation:

The area is the product of the dimensions. 1 km = 1000 m.

  A = (550 m)(550·1000 m) = 302,500,000 m^2

The price per square meter is ...

  206,250,000/302,500,000 peso/m^2

  = 15/22 peso/m^2 ≈ 0.68182 peso/m^2
