Lena [83]

The perimeter is the sum of all the sides of the figure⇒

151

$P=a+b+c+d...$

$P=(y+9)+(3y+3)+(4y+6)=y+9+3y+3+4y+6=8y+18$

152

$P=a+b+c+d...\\P=(4a-100)+(2a-15)+(2a+40)=4a-100+2a-15+2a+40=\\=8a-75$

help im stuck pls -- Refer to the table above. Determine the percent of all voters that did not vote Republican or Democrat but

dsp73

Answer:

9.9%

Step-by-step explanation:

Well, you would just divide the "other" category and the "total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:

$\frac{222}{2222} =0.09999...\\$

Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:

9.9%, which could be rounded to 10% or 9%.
