Option B: \frac{AB}{BC}=\frac{AE}{ED} is sufficient to prove that BE ll CD

Explanation:

Given that ACD is a triangle.

The line EB intersects the sides AC and AD of the triangle.

The point E intersect the side AD and B intersect the side AC.

We need to prove that BE ll CD

Then, the side splitter theorem states that "If a line intersects two sides of a triangle and divides the sides proportionally, the line is parallel to the third side of the triangle".

From the side splitter theorem, the line EB intersects the two sides of the triangle AC and AD and divides the sides proportionally.

Thus, the proportion of the sides is given by

\frac{AB}{BC}=\frac{AE}{ED}

This proportionality shows that the line is parallel to the third side of the triangle.

Hence, \frac{AB}{BC}=\frac{AE}{ED} is sufficient to prove that BE ll CD

Therefore, Option B is the correct answer.

A blacksmith blends one alloy of silver that is 35% silver and another that is 95% silver. To the nearest ton, how much of the a
hammer [34]

Answer:

Let x be the unknown quantity of 50% silver.

Look at the silver concentrations...   This will be 0.5x of actual silver,

Added to 5% silver in 500g or 0.05(500)g of actual silver

Totaling to (500+x)g of 20% silver which will have 0.2(500+x)g of silver

 

Your equation is:

 

0.5x + 0.05(500) = 0.2(500+x)

 

Solve for x to find the grams of 50% silver used

The time it takes for an object stopped from a certain speed can be modeled by the equation
yanalaym [24]
Given: 
t = 1/2 √v
v = speed of object meters per second

t = 3 seconds

3 = 1/2 √v
3 * 2 = √v
6 = √v
6² = √v²
36 meters = v

v = 36 meters per second

Find the distance between (3,4) and (4,-6) if necessary, round to the nearest tenth.
Ratling [72]

Answer:

The distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

Step-by-step explanation:

Given the points

  • (3,4)
  • (4,-6)

The distance 'd' between (3,4) and (4,-6)

\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):

d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

substituting the points values

   =\sqrt{\left(4-3\right)^2+\left(-6-4\right)^2}

   =\sqrt{1+10^2}

   =\sqrt{1+100}

   =\sqrt{101}

   =10.0  units (Rounded to the nearest the Tenths Place)

Thus, the distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)
