tyler has a rectangular garden measuring 12m by 20 m that he wants to split diagonally from corner to corner using a fence. how
adelina 88 [10]

Answer:

23.3

(or 4\sqrt{34} (let me know if you wanted this one and is you want it explained) lol)

Step-by-step explanation:

To find the length of the fence, use the Pythagorean theorem because, if you cut a rectangle diagonally, you will create two right triangles, and this formula only works with right triangles:

a^{2} +b^{2} =c^{2}

Insert values:

12^{2} +20^{2} =c^{2}

Solve for c:

Evaluate exponents

144+400=c^2

Simplify addition

544=c^2

Find the square root of both

\sqrt{544} =\sqrt{c^2}\\\\\sqrt{544} =c\\\\23.324=c\\\\c=23.3

The fence needs to be approximately 23.3 m.

algol [13]

Answer:

Jon did determine the probability correctly.

Step-by-step explanation:

<em>In Jon's closet, there are a total of 24 clothes. Among those pieces of clothing, there are a total of 9 out of 24 clothes that are black. There are also 11 shirts out of 24 clothes. </em>

<em />

<em>When a probability has OR in it, it means to add.</em>

<em />

<em>11/24 plus 9/24 gives you 20/24.</em>

<em />

<em>Therefore, Jon is correct.</em>

The triangles below are similar. Find x showing the proportion and all work.
zavuch27 [327]

we are given that

two triangles are similar

so, the  ratio of their sides must be same

we get

\frac{2}{6} =\frac{x}{x+2}

now, we can solve for x

step-1: Cross multiply both sides

2(x+2) =6x

step-2: Simplify left side

2x +4 =6x

step-3: Subtract both sides by 2x

2x +4-2x =6x-2x

4 =4x

step-4: Divide both sides by 4

x=1

so,

x=1............Answer
