Answer:
380ft
Step-by-step explanation:
Assuming the balloon rises 525ft from sea level (0ft), all we need to do is subtract both numbers to find the new height.
525 - 145 = 380ft
There could be many different scenarios though because if the question provides the height of land off sea level, you would have to take that into account as well.
Best of Luck!
Answer:
-88 mph
Step-by-step explanation:
We can use the relation ...
time = distance/speed
to compare the times in the two directions.

The wind speed is -88 miles per hour.
_____
The problem statement tells us the travel is slower <em>with</em> the wind than <em>against</em> the wind. Hence "with the wind" must be subtracting from the net speed. That is, the wind speed is negative.
Well here are 3
(0,7);(1,11);(2,15)
4(0) + 7 y:7
You can keep doing it choose a number for x that's and for y multiply 4 times the numer you choosed for x and add 7 to it
This is simple proportions, because of their similarity:
