Sally paid $3.82 while Martha paid $1.82 (which makes a total of $5.64 and shows that Sally paid $2 more than Martha)
Area of a rectangle=length x width
You have two rectangles:
First rectangle (the biggest):
length=9 yd
width=12 yd-6 yd=6 yd
Area of the biggest rectangle=(9 yd)(6 yd)=54 yd²
Second rectangle (the smallest)
length=6 yd
width=3 yd
Area of the smallest rectangle=(6 yd)(3 yd)=18 yd²
Area of the ballroom=area of the biggest rectangle + area of the smallest rectangle.
area of the ballroom=54 yd² +18 yd²=72 yd²
The appropriate choice is ...
A. 3 radians
_____
Arc length (s) is given in terms of radius (r) and central angle (θ) in radians by the formula
s = rθ
When you substitute your given information, you have
3r = rθ
Dividing by r gives
θ = 3 . . . . . . . radians
4a-13=19 add 13 to both sides
4a=32 divide by 4 on both sides
a=8
By dropping acorns, and spreading them to other areas by animals and wind.
