A parallelogram has verticies of (0,0) (0,6) (4,4) (4, -2). Which transformation maps the parallelogram onto itself?
gulaghasi [49]

The transformation that would map the parallelogram onto itself is the rotation of 180 degrees about the point (2, 2)

<h3>What is a transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Rigid transformation is the transformation that does not change the shape or size of a figure. Examples of rigid transformations are <em>translation, reflection and rotation</em>.

The transformation that would map the parallelogram onto itself is the rotation of 180 degrees about the point (2, 2)

Rolex buys computer disks at a price of 4 for $5 and sells them at a price of 3 for $5. How many computer disks must he sell to
Lina20 [59]

Given that Rolex buys computer disks at a price of 4 for $5 .

That means cost price of 1 disk = 5/4


Given that Rolex sells them at a price of 3 for $5.

That means selling price of 1 disk = 5/3


Profit on 1 disk = selling price - cost price

Profit on 1 disk = \frac{5}{3}-\frac{5}{4}

Profit on 1 disk = \frac{5}{3}\cdot\frac{4}{4}-\frac{5}{4}\cdot\frac{3}{3}

Profit on 1 disk = \frac{20}{12}-\frac{15}{12}

Profit on 1 disk = \frac{5}{12}

Now we have to find how many disk to be sold to get the profit $100

so we just divide $100 by profit on 1 disk

\frac{100}{\left(\frac{5}{12}\right)} = 100\cdot\frac{12}{5} = 240

Hence final answer is 240 disks.
