Answer:

A transformation is a way of moving or changing a figure. There are three types of basic transformations that preserves the size and shape of the figure. These three, reflections, rotations, and translations, are called isometrics.

Answer:

$8.75

Step-by-step explanation:

To calculate this you could use two methods. The first method is to find out what 10% is and multiply it by 5. The second method is to calculate 50% using the formula.

Method 1:

To work this out you would simply divide 17.50 by 10, which is 1.75. This is because percentages are out of 100 and so by dividing by 10 we are finding out what 10% is. Then you would multiply 1.75 by 5, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.

1) Divide 17.50 by 10.

$17.50/10=1.75$

2) Multiply 1.75 by 5.

$1.75*5=8.75$

3) Minus 8.75 from 17.50.

$17.50-8.75=8.75$

4) The new price is $8.75

Method 2:

The formula for percentages is.

$\frac{percentage}{100} * amount$

To work this out you would first divide 50 by 100, which gives you 0.5. Then you would multiply 0.5 by 17.50, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.

1) Divide 50 by 100.

$50/100=0.5$
