Answer:

Mrs. Alexa has to buy one whiteboard marker for her class every week because her students keep stealing them. Each marker costs three dollars. The school has given her $25 for her school expenses. If she uses the money from the expenses to buy markers, how much money will she have after five weeks?

She has 10 dollars after five weeks.

Step-by-step explanation:

-3 is the price of each marker reducing her overall money.

5 is how many markers she should buy in 5 weeks.

$25 is the money grant that the school gave her.

A store advertises 15% off an item that regularly sells for $300.
Ilia_Sergeevich [38]

Regular price = 300

Sale = 15%

= 300 - 45

Help please worth 57 points
Alisiya [41]

Answer:

Step-by-step explanation:

A line segment is always similar to another line segment, because we can always map one into the other using only dilation a and rigid transformations

we know that

A dilation is  a Non-Rigid Transformations that change the structure of our original object. For example, it can make our object bigger or smaller using scaling.

The dilation produce similar figures

In this case, it would be lengthening or shortening a line. We can dilate any line to get it to any desired length we want.

A rigid transformation, is a transformation that preserves distance and angles, it does not change the size or shape of the figure. Reflections, translations, rotations, and combinations of these three transformations are rigid transformations.

so

If we have two line segments XY and WZ,  then it is possible to use dilation and rigid transformations to map line segment XY to line segment WZ.

The first segment XY would map to the second segment WZ

therefore

A line segment is always similar to another line segment, because we can always map one into the other using only dilation a and rigid transformations
