100x70 = 7000
7000/20= 350

Try choosing 7 democrats and then choosing a random republican
A.) Here, w = 550kg/m^3.
Therefore, S = (0.032(550) - 2.5)/10000 = 0.00151
After drying, the beam will be (1 - 0.00151) x 12.027 = 12.009
b.) 0.0012 = (0.032w - 2.5)/10000
0.032w - 2.5 = 12
0.032w = 12 + 2.5 = 14.5
w = 14.5/0.032 = 453 kg/m^3
Therefore, the required water content is 453 kg/m^3
The perimeter of the figure is 20.73 cm.
<h3>What is perimeter:</h3>
Perimeter is a closed part that surrounds a two dimensional or one length figure.
The perimeter of the figure above is the sum of the wholes sides. In other word the sum that surrounds the whole sides.
Therefore, the perimeter of the figure is as follows:
perimeter = 3.1 + 5.2 + 4.24 + 2.19 + 6
perimeter = 8.3 + 4.24 + 2.19 + 6
perimeter = 12.54 + 2.19 + 6
perimeter = 14.73 + 6
perimeter = 20.73 cm
Therefore, the perimeter of the figure is 20.73 cm.
