Find the ratio created when AB is partitioned by C.

Blizzard [7]

Answer:

Step-by-step explanation:

From the picture attached,

Segment AB has been divided into four equal parts.

Let each part measures equal length = 1 unit

Point C is 2 units apart from both the points A and B.

Length of AC = Length of BC = 2 units

Therefore, point C will be the mid point of segment AB.

And ratio of AC and BC = 1:1

AC:BC = 1:1

Similarly, AC:AB = 2:4

= 1:2

And BC:AB = 2:4

= 1:2

What is the value of x in the equation x - y = 30, when y = 15?<br> O4<br> O 8<br> O 80<br> O 200

olganol [36]

$\frac{1}{5}x - \frac{2}{3} y = 30 \\$

Putting the value of Y = 15

$\frac{1}{5} x - \frac{2}{3} \times 15 = 30 \\ \frac{1}{5} x = 30 + 10 \\ \frac{1}{5} x = 40 \\ x = 5 \times 40 \\ x = 200$

So, X = 200

Does anyone know how to find the side length of this square.if so then, i will mark brainlist.

kvv77 [185]

Hello!

To find the side length you use the equation

$a = \sqrt{2} \frac{d}{2}$

a is side length
d is diagonal

Put in the number we know

$a = \sqrt{2} * \frac{27}{2}$

Divide

$a = \sqrt{2} * 13.5$

Multiply

a = 19.091

The answer is 19.09

Hope this helps!
