Step-by-step explanation:
Answer:
48cm^2
Step-by-step explanation:
We can break the composite figure into two pieces.
We take the bottom rectangle and determine its area
The figure is 10 cm by 2 cm
A = 10*2 = 20cm^2
The height of the vertical rectangle is 9 cm -2 cm = 7 cm
The width is 10 cm - 6 cm = 4 cm
The figure is 7 cm cm by 4 cm
A = 7*4 = 28cm^2
The total area is the sum of the two areas
20 cm^2 + 28 cm^2 = 48 cm^2
Answer:
B and C
Step-by-step explanation:
The ratio of black to white is 5:6
The only mixtures that have this ratio is B and C
50+20+10+5+1 = $86
.25+.10+.05+.01= 41¢
$100 - $86.41
=
$13.59
