Answer:
a.300th customer
b.$180
Step-by-step explanation:
Area of a circle for (360degrees) = pi*(r^2)
Area of part of a circle with angle θ=(θ/360)*(pi*)*(r^2)
<span>(θ/360)*pi*(6^2)=12*pi
</span>solving, <span>θ=(12/36)*360
</span><span>θ=120 degress
</span>
Total Area
= Area of semicircle (radius 6/2=3) + Area of rectangle (sides 6 and 10)
= 2 x Pi* (3)^2 + (10 x 6)
= 116.55
0,8 is the answer because 5*6+1/6=5,2 and 6-5,2=0,8
The answer is 3a+b=a-15. Substitute the equation where b is.
