Diameter x pi (3.14) OR 2 x radius x pi
It would be x^10. When you multiply you add the exponents
Alice spends $3 per day, so for in a week and upto 5 weeks, Alice spend =$3*5*5 = $75
Betty spends $ 25 every 2 weeks, so for 5 weeks , she spends= 25+25+12.5
= $62.5
Cindy spends $ 75 per month, and on an average there are less then 5 weeks in a month . SO for 5 week, it must be greater than $75 .
So the order is
Cindy>Alice>Betty
ANSWER
x=12, y=10
EXPLANATION
The diagonals of a parallelogram bisect each other.
This implies that;
AE=EC
Also, DE=EB;
Put equation (2) in (1).
Expand;
Put x=2, into equation (2).
The sum of all the angles in a triangle should always add up to 360° and seeing that this is an isosceles triangle 2 of the angles should be equal.
So there would be 2 30° angles and 360-60=300 so the 3rd angle would be equal to 300° . Hope this helps!
