A summer camp cookout is planned for the campers and their families. There is room for 450 people. Each adult costs $7, and each
camper costs $4. There is a maximum budget of $1,150. Write the system of inequalities to represent this real-world scenario, where x is the number of adults and y is the number of campers. x + y ≤ 1,150 7x + 4y ≤ 450 x + y ≤ 450 7x + 4y ≤ 1,150 x + y ≤ 1,150 4x + 7y ≤ 450 x + y ≤ 450 4x + 7y ≤ 1,150
<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>
