Answer:
22 feet
Step-by-step explanation:
33 x 2/3 = 22
R/2 - r. i think... I'm not so sure. You divide 2 and r then subtract r.
M = (x1 +x2)/2 , (y1 + y2)/2
M = (3.2+1.6)/2 , (2.5 - 4.5)/2
M = (2.4, -1)
Answer: 5.60
Step-by-step explanation:
20% of 64 = 12.8 / 12.80 so you would then add 64 to 12.8 and that gets you 76.8
76.8 ÷ 3 = 25.6 so paying with a twenty dollar bill would mean you still owed 5.60.
Answer:
55 adult tickets were sold on Friday.
Step-by-step explanation:
A linear system will be used to model the system.
Let c be the number of child tickets and a be the number of adult tickets
Then according to given statements
![a+c = 133\ \ \ \ Eqn\ 1\\9.50a+5.20c = 928.10\ \ \ Eqn\ 2](https://tex.z-dn.net/?f=a%2Bc%20%3D%20133%5C%20%5C%20%5C%20%5C%20Eqn%5C%201%5C%5C9.50a%2B5.20c%20%3D%20928.10%5C%20%5C%20%5C%20Eqn%5C%202)
From equation 1
![a = 133-c](https://tex.z-dn.net/?f=a%20%3D%20133-c)
Putting this in equation 2
![9.50(133-c)+5.20c = 928.10\\1263.5-9.50c+5.20c=928.10\\1263.5-4.3c = 928.10\\-4.3c = 928.10-1263.5\\-4.3c=-335.4\\\frac{-4.3c}{-4.3} = \frac{-335.4}{-4.3}\\c = 78](https://tex.z-dn.net/?f=9.50%28133-c%29%2B5.20c%20%3D%20928.10%5C%5C1263.5-9.50c%2B5.20c%3D928.10%5C%5C1263.5-4.3c%20%3D%20928.10%5C%5C-4.3c%20%3D%20928.10-1263.5%5C%5C-4.3c%3D-335.4%5C%5C%5Cfrac%7B-4.3c%7D%7B-4.3%7D%20%3D%20%5Cfrac%7B-335.4%7D%7B-4.3%7D%5C%5Cc%20%3D%2078)
Putting c = 78 in equation 1
![a+78 = 133\\a = 133-78\\a = 55](https://tex.z-dn.net/?f=a%2B78%20%3D%20133%5C%5Ca%20%3D%20133-78%5C%5Ca%20%3D%2055)
Hence,
55 adult tickets were sold on Friday.
