⌒DE = 110°
⌒AC = 85° + 25° = 110°
Both arcs have the same measurement; so the chords are the same.
Initially, Ball A of 10 kg will have velocity x, while Ball B of 30 kg has velocity -10 m/s.
After collision, Ball A will have a velocity of -30 m/s, while Ball B will have velocity 10 m/s. We assume their masses do not change.
(10 kg)(x m/s) + (30 kg)(-10 m/s) = (10 kg)(-30 m/s) + (30 kg)(10 m/s)
10x - 300 = -300 + 300
x = 30 m/s (to the right)
Answer:
( -2,5)
Step-by-step explanation:
To find the x coordinates of the midpoint, add the x coordinates of the endpoint and divide by 2
( -9+5)/2 = -4/2 = -2
To find the y coordinates of the midpoint, add the y coordinates of the endpoint and divide by 2
( 3+7)/2 = 10/2 = 5
The midpoint is ( -2,5)
Answer:
25
Step-by-step explanation:
p=n+20
p=5n
5n=n+20
n=5
p=20+5
p=25
Answer:
Lowest: 78
Highest: 99
Step-by-step explanation:
Quiz 1 =A
Quiz 2 = B
B = 21 + A
2A = 57 + B
2A = 57 + (21 + A)
2A = 78 + A
A = 78
B = 21 + A
B = 21 + 78
B = 99
