You can probably look up a answer key for that worksheet. ;)
Answer:
Step-by-step explanation:
sub in all your x values into the linear equation it gives you
once you have your table you should be able to figure out the rest if the questions !!
Equation
Total = movies plus songs.
Givens
Total = 100
Movies = 48.4
Songs Cost = x
Number of Songs = 40
Solve
100 = 48.4 + 40x Subtract 48.4 from both sides.
100 - 48.4 = 40x
51.6 = 40x Divide by 40
51.6 / 40 = x
1.29 = x
Conclusion
Each song cost $1.29
Answer:
0.0622ns
Step-by-step explanation:
Rate, R = 6mm²/s or 6 X 10∧-8m²/s
Radius, r = 109 X 10∧-9m
Area of circular object = πr² = 22/7 X (109 X 10∧-9)²= 3.734 X 10∧-14m²
Speed = 3.734 X 10∧-14m²/(6 X 10∧-8)m²/s = 0.0622ns
The answer is 221,448,757.5
