Answer:
66.5 cm²
Step-by-step explanation:
A horizontal line at the "knee" on the right will divide the figure into a 4 cm by 2 cm rectangle, and a trapezoid with bases 4 cm and 9 cm, and height 11-2 = 9 cm. Then the total area of the figure is ...
A = LW + 1/2(b1 +b2)h
A = (4 cm)(2 cm) + (1/2)(4 cm +9 cm)(9 cm) = 8 cm² +58.5 cm²
A = 66.5 cm² . . . . area of the figure
Answer:
Step-by-step explanation:
circumference=πd=π×18=18π in
distance covered in 1 sec=18π×10=180π in.
distance covered in 1 min=180π×60=10800π in
distance covered in 60 min=10800π×60=648000π in=648000π÷12=54000π ft
=54000π÷3=18000π yards=18000π÷1760≈32.13 miles per hour.
1 : 115 ( add it up )
2 : 180 ( obtuse angle )
3 : 109 ( add it up )

Answer:
X= 13
A=104
C=26
Step-by-step explanation:
the equation is 8x+2x+50=180
10x=130
x=13
9c + 15d = 87
I don't know how to use the equation to answer it, but 4 DVDs were bought, and 3 CDs were bought.
