Find the area of the parallelogram.
vodka [1.7K]

Answer:

  264 ft²

Step-by-step explanation:

The right triangle shown at the right end of the figure has a missing leg that can be found using the Pythagorean theorem. (If you recognize the triangle as a 5-12-13 triangle, you already know its length is 12 ft.)

  a² +b² = c²

  5² + b² = 13²

  b² = 169 -25 = 144

  b = √144 = 12

So, the height of the parallelogram is 12 ft, and its base length is 22 ft. The area is the product of these ...

  A = bh = (22 ft)(12 ft) = 264 ft²

What is the next fraction in this sequence? Simplify your answer. 5 6  ,   5 9  ,   10 27  ,   20 81  
san4es73 [151]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~

So we know that all the denominators are multiples of 3, and the numerators are multiples of 2...

we also know that the fraction 5/6 is a dummy fraction (which means, it will not help us at all)

We know that the numerators (from 5/9 and on), are constantly multiplied by 2, and the denominators (from 5/9 and on) are constantly multiplied by 3...

So by this information, we know that the answer must be 40/243

This is because 20 * 2 = 40

And 81 * 3 = 243

So... put them together, and you get 40/243

An isometry is a type of transformation that preserves the length of a figure's sides. Using this definition, which of the follo
den301095 [7]

Answer:

Stretch

Step-by-step explanation:

- Translation: A translation moves a shape up, down or from side to side but it does not change its size.

- Reflection: A reflection is a transformation which all the points of an object reflect or flip on a line called the axis of reflection or line of reflection. This transformation does not change its size.

- Rotation: A rotation is a transformation  that turns a figure about a fixed point called the center of rotation. This transformation does not change figure's size.

- Stretch: A stretch is a transfoormation which stretch the figure (by multiplying by C>1). This transformation changes the size of the figure.

- Isometry: An isometry is a type of transformation that preserves the length of a figure's sides.

Thus, a stretch is not an isometry

Зу = - 2x + 12 how do you graph this equation ​
evablogger [386]

Explanation:

Start out by dividing all terms by 3 to put the equation in PROPER Slope-Intercept Form:

\displaystyle \frac{3y}{3} = \frac{-2x + 12}{3} \\ \\ y = -\frac{2}{3}x + 4

Now, starting from the y-intercept of [0, 4], you do \displaystyle \frac{rise}{run}by either moving two blocks <em>north</em> over three blocks <em>west</em> or two blocks <em>south</em> over three blocks <em>east</em> [<em>west</em> and <em>south</em> are negatives].

I am joyous to assist you anytime.

How to find a slope between two points?
Jobisdone [24]
Well the best way is to plug into the slope equation
m =  \frac{rise}{run}  =  \frac{y2 - y1}{x2 - x1}
Where (x1, y1) and (x2,y2) are ordered pairs on the xy plane.
