Answer:
$6.6
Step-by-step explanation:
you want to find out what 40% of the original price is ($11)
100% = 11
10%= 1.1
to get 40% you times it by 4
40%= 4.4
you then have to take away the sale reduction from the original
11- 4.4 =$6.6
Let's first find how many students bring their lunch to school. This is 30% of 300. To find this value, convert the percentage to a fraction (or decimal) and multiply:

Since 90 students bring their lunch to school, we can say 210 students do not bring their lunch to school. (300 - 90 = 210)

Step-by-step explanation:
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) Find the area
we know that
The area of the shape is equal to the area of a quarter of circle minus the area of an isosceles right triangle
so

we have that the base and the height of triangle is equal to the radius of the circle

substitute


simplify
Factor 36

Part 2) Find the perimeter
The perimeter of the figure is equal to the circumference of a quarter of circle plus the hypotenuse of the right triangle
<em>The circumference of a quarter of circle is equal to</em>

substitute the given values


The hypotenuse of right triangle is equal to (applying the Pythagorean Theorem)


simplify

Find the perimeter

simplify
Factor 6
