Answer:
(20,-7)
Step-by-step explanation:
x+2y=6
x = 6-2y
3x+8y=4
3(6-2y)+8y=4
18-6y+8y=4
2y=-14
y = -7
x=6-2(-7)
x = 20
If it is parallel then x would be A) 28
Answer:
400.00
Step-by-step explanation:
20*20 is close to 2*2. Since we have zeros, we can multiply 2 and 2 to get 4. Then we add two zeros because of the zero in 20 and the zero in the other 20. This could also be written as
because we're multiplying 20 by itself.
Answer:
wouldn't be $30 all together
Step-by-step explanation:
Answer:
Perfectly inelastic collision is type of collision during which two objects collide, stay connected and momentum is conserved. Formula used for conservation of momentum is:
In case of perfectly inelastic collision v'1 and v'2 are same.
We have following information:
m₁=3 kg
m₂=? kg
v₁=x m/s
v₂=0 m/s
v'1 = v'2 = 1/3 * v₁
Now we insert given information and solve for m₂:
3*v₁ + 0*? = 3*1/3*v₁ + m₂*1/3*v₁
3v₁ = v₁ + m₂*1/3*v₁
2v₁ = m₂*1/3*v₁
2 = m₂*1/3
m₂= 6kg
Mass of second mud ball is 6kg.
