Answer: 73
Step-by-step explanation:
You use the bowtie method to get the answer for this problem. This is where you do 4/15 and x/273. You multiply 4 by 273 and x by 15. Resulting in the answers 1092 and 15x. To find the value of x, you divide 1092 by 15. and get 72.8. I rounded up to 73.
Answer:
Plane speed x mph
wind speed 20 mph
against wind x - 20 mph
with wind x + 20 mph
Distance against wind 140
Distance with wind 160
Time = same equate the time against with time with current
t=d/r
140 /(x- 20 )= 160 /(x+ 20 )
140 *(x+ 20 )= 160 *(x- 20 )
140 x + 2800 = 160 x -3200
140 x -160 x = -3200 + -2800
-20 x = -6000
/ -20
x= 300 mph
Answer:
Step-by-step explanation:
x^3 = -216 yields 1 real, rational solution: 6
x^3 = 25 yields 1 real solution, but this solution is irrational:
∛-25 = -∛25 ≈ -2.92
