The answer to the question is:
12 7/15
Since it is 11 22/15. When you have 15/15 it makes a whole. Then whatever you have left you make a fraction again.
First you create a proportion (30/100=x/120). After you solve this, next you subtract this answer from 120. Then create a proportion for 40% (40/100=x/120). Then add this number to the first answer you got when you subtracted the answer from your first proportion from 120.
6 lessons per week multiplied by the number of weeks in a year

Answer:
Step-by-step explanation:
20 is greater than y.
We know that
<span>Of all the rectangles having same area, square has the least perimeter
</span>
area of square=x²
where
x is the length side of the square
A=72 cm²
72=x²
x=√72-----> x=6√2 cm
Perimeter of square=4*x------> 4*(6√2)-----> P=24√2 cm
P=33.94 cm
the answer is
the perimeter is equal to 24√2 cm or 33.94 cm
