<span>Semicircle area = circle area / 2 = (pi*r^2)/2
16 in is the radius. Let's call the area of this semicircle s.
3.14*16^2=s
</span><span>Trapezoid area = ((base 1 + base 2) / 2) * h
Here, base 1 is 44 and base 2 is 36. The height (h) is 20. Let's call this trapezoid's area t.
(44+36)/2 *20 = t
</span>
<span>We can remove the area of the semicircle (that created by the windshield wiper) by subtracting it from the area of the trapezoid.
t - s = uncleaned area
[(44+36)/2 * 20] - [3.14 * 16^2] = uncleaned area</span>
(3x-5)+(x+1)=180
x=46
3(46)-5=133

D. All irrational numbers are rational numbers.
I attached the diagram my teacher showed us when we learned about this. I think it makes it a lot less confusing.
Hope this helps :)
Answer: you just flip it. It would be the opposite.
Step-by-step explanation:
When you flip it, what’s the difference? It’s still the same.
