Answer: 219.52 inch^2
Step-by-step explanation:
Given the dimensions of rectangular papaerboard:
Length = 20inches
Width = 16inches
Area of rectangle = Length × width
Area of rectangle = 20 × 16 = 320 in^2
Area of a circle = pi*r^2
Therefore, area of semicircle = (pi*r^2) / 2
Diameter of circle = width of rectangle = 16 inches
Radius = diameter / 2 = 16 /2 = 8inches
Therefore, area of semicircle = (pi*8^2) / 2
= (3.14 × 64) / 2
= 200.96 / 2
= 100.48 inch^2
Therefore, area of paperboard left :
Area of rectangle - area of semicircle
320 - 100.48
= 219.52 inch^2

Step-by-step explanation:
1945 of the songs are on Ava's phone.
<h3><u>Calculus</u> </h3>
Given that both Marquis and Ava have extensive music collections on their phones, and together they have a total of 4210 unique songs, to determine, if Marquis has 320 more unique songs than Ava does, how many of the 4210 songs are on Ava's phone, the following calculation must be performed:
- (4210 - 320) / 2 = X
- 3890 / 2 = X
- 1945=X
Therefore, 1945 of the songs are on Ava's phone.
