Here, we are required to find the area of the paper board given after the semicircle is cut out of it
Area of the paper board thatremains is 423 in²
Length = 29 in
Width = 20 in
Area of a rectangle = length × width
= 29 in × 20 in
= 580 in²
Area of a semi circle = πr²/2
π = 3.14
r = diameter / 2 = 20 in / 2 = 10 in
Area of a semi circle = πr²/2
= 3.14 × (10 in)² / 2
= 3.14 × 100 in² / 2
= 314 in²/2
= 157 in²
The semicircle is cut out of the rectangle
Find the area of the paper board that remains after the semicircle is cut out of it by subtracting the area of a semi circle from the area of a rectangle
Area of the paper board that remains = Area of a rectangle - Area of a semi circle
= 580 in² - 157 in²
= 423 in²

Step-by-step explanation:
Answer:
84%
Step-by-step explanation:
The probability of Thomas bumping into her at school is 80%, so the probability of not bumping into her is 100% - 80% = 20%.
If he doesn't bump into her (20% chance), he will call her, and the probability of asking her in this case is 60%, so the final probability of asking her in this case is:
![P_1 = 20\% * 60\% = 12\%](https://tex.z-dn.net/?f=P_1%20%3D%2020%5C%25%20%2A%2060%5C%25%20%3D%2012%5C%25)
If he bumps into her (80% chance), the probability of asking her is 90%, so the final probability of asking her in this case is:
![P_2 = 80\% * 90\% = 72\%](https://tex.z-dn.net/?f=P_2%20%3D%2080%5C%25%20%2A%2090%5C%25%20%3D%2072%5C%25)
To find the probability of Thomas inviting Madeline to the party, we just have to sum the probabilities we found above:
![P = P_1 + P_2](https://tex.z-dn.net/?f=P%20%3D%20P_1%20%2B%20P_2)
![P = 12\% + 72\% = 84\%](https://tex.z-dn.net/?f=P%20%3D%2012%5C%25%20%2B%2072%5C%25%20%3D%2084%5C%25)
