Answer:
( 50, 30 )
Step-by-step explanation:
Equal distance
Answer:
86.67%
Step-by-step explanation:
Answer: 32.8kgm^2/s
Step-by-step explanation:
1. Angular momentum is a product of linear momentum and the distance of the object from a rotation axis.
2. Linear momentum (L) is given as :
L = mv
Where: m= mass = 4kg
v= velocity= 2m/s
=> L = 8kgm/s
Angular momentum (A) = L x centre distance (d) of object from a rotation axis
d = √(0.9-0)^2 + (10-6)^2 = 4.1m
=> A = 8 x 4.1 = 32.8kgm^2/s.
First, we need to get the variable by it self.
-2x+6=20
-6=-6
-2x=14
Next, since the operation is multiplication, we need to divided both sides by -2.
X=-7
Answer:
2.1 months
Step-by-step explanation:
Let x represent the number of months
Set up expressions to represent the cost of each Internet provider
40x + 39 will represent the first one
30x + 60 will represent the other
Set these equal to each other and solve for x:
40x + 39 = 30x + 60
10x + 39 = 60
10x = 21
x = 2.1
So, the cost will be the same in 2.1 months
