Answer:

The length of AB is 19.

Step-by-step explanation:

Lengths BC and AD are congruent to each other.

BC: 17x + 4 equals AD:18x

17x + 4 = 18x .... that's the equation it makes and the equation we are going to solve.

$\ 17x + 4 = 18x \\ \frac{ - 17x \: \: \: \: \: \: \:\: = - 17x} {4 = 1x} \\ \\ \frac{4 }{1} = \frac{1x}{1} \\ 4 = x$

Since we found out the value for 'x', now we are going to plug it in 4x + 3.

$4x + 3 \\ 4(4) + 3 \\ 16 + 3 \\ 19$

The length of AB is 19.

Calculate the area shaded

Rudiy27

Answer:

7.722 cm^2

Step-by-step explanation:

Step 1: Find the area of the square.

Area of square = s^2, where s = side
6^2 = 36 cm^2

Step 2: Find the area of the circle.

We are given the diameter of the circle as 6 cm, so the radius must be 3 cm.
Area of circle is $\pi r^2$ , so now we plug in and simplify.
$3.142 * 3^2$
$3.142 * 9$
$28.278$

Step 3: Subtract area of circle from area of square.

$36 - 28.278$
$7.722$

Therefore, the area of the shaded region is 7.722 cm^2.

Consider a steel ball floating on the surface of mercury in a half-filled container. What happens when the rest of the container

Helen [10]

Answer

The steel ball will be caught up in between the mercury and water medium.

Step-by-step explanation:

Mercury with a density of 13546 kg/m^3

water with a density of 1000 kg/m^3
Steel with a density of 8050 kg/m^3

From the factual density of both substances given above ,it shows that mercury is more heavier than water. In that case mercury will be at the lower layer when mixed with water.

The steel ball will be caught in between both mixtures as the density of steel is 8050 kg/m^3.Which is more than Water but less than Mercury.
