No could be represented as N, Yes can be Y, and X can be neither.  You have to first see how many people they asked in total.  So add 1225, 498, and 395.  You get 2118.  So that would be the bottom number on all the fractions.

No would be 1225/2118

Yes would be 498/2118

Neither would be 395/2118

You have to be sure you'd put like N=1225/2118 and y=498/2118 and x=395/2118

So you only need to solve for yes.  So the other information should have been included so you could get the total number of people who answered, aka "the bottom number"

so yes is 498/2118 and you have to represent it with a number, I chose y.  But usually they like x if there is only one to solve for.

You need to reduce. With such a high number it can be tough.  But I can see right way I can do 2.

498 divided by 2 is 249.  2118 divided by 2 is 1059.

That makes it y=249/1059

Both of those can reduce by 3.  249 divided by 3 is 83.  1059 divided by 3 is 353.

That makes y=83/353

That's the lowest it can go.

I’m really stuck on this. Would someone please help?
zavuch27 [327]

Since MN forms a 180 degree angle, if you subtract 148.7 from 180, you get 31.3 degrees. This means angles L and N are both 31.3 degrees. Since the parallelogram is 360 degrees total, you subtract 62.6 to account for angles L and N. The remaining degrees unaccounted for are 297.4 degrees which you then divide by two to get the value of angles O and M, which would give you 148.7 degrees for each O and M. This means that angle x is 148.7 degrees

Find the approximate perimeter of the trapezoid? PLSSS HELPPP
choli [55]

Answer:

49

Step-by-step explanation:

side 1 = |18-3|= 15

side 2 = |12-3| = 9

side 3 = |16-4| = 12

side 4: \sqrt{(18-12)^2 + (4-16)^2} \\ \sqrt{36+144} \\ = \sqrt{180} \\ = 13,4

perimeter = 15 + 9 + 12 + 13,4= 49,4 = 49
