Answer:
Step-by-step explanation:
Plan A: 10 CDs costs $2.30, so 1 CD cost $0.23
Plan B: A package of 50 CDs cost $10.5, so 1 CD cost $1.05
0.23 < 1.05
Choose Plan A
Answer:
The speed of the plane with no wind is 378 miles per hour.
Step-by-step explanation:
Since at maximum speed, an airplane travels 1680 miles against the wind in 5 hours, and flying with the wind. the plane can travel the same distance in 4 hours, to determine what is the speed of the plane with no wind, the following calculation must be performed:
Against the wind = 1680/5 = 336
With the wind = 1680/4 = 420
420 - ((420 - 336) / 2) = X
420 - 42 = X
378 = X
Therefore, the speed of the plane with no wind is 378 miles per hour.
<h2>
Option C is the correct answer.</h2>
Step-by-step explanation:
Diameter, D = 42 feet
Circumference = πD = π x 42 = 131.95 feet
Number of rotations per minute = 3
Total time = 5 minutes
Total rotations = 5 x 3 = 15
Distance traveled per rotation = 131.95 feet
Distance traveled in 15 rotations = 15 x 131.95 = 1978 feet
Option C is the correct answer.
2n/3 - 11 = n + 4
Add 11 to both sides:
2n/3 = n + 15
Multiply both sides by 3:
2n = 3n + 45
Isolate n:
-n = 45
n = -45
Answer:
The answer would be y= |x-2| -1.
When graphing the answer B would be a larger quantity but A is the correct answer. Hope this helps :))
