Answer:
42 hours
Step-by-step explanation:
Natalie needs to save a total of $479.58
She already saved $149.98
The amount left to save is
= 479.58-149.98
= 329.7
If she earns 7.85 dollars working per hour then the number of hours she can work to get $329.7 can be calculated as follows
= 329.7 / 7.85
= 42
Hence Natalie will work for 42 hours to meet her goals
Answer:
Step-by-step explanation:
After some number of minutes m, Mohammed's altitude will be ...
40 +10m
and Dana's altitude will be ...
165 -15m
The altitudes will be the same when ...
40 +10m = 165 -15m
25m = 125 . . . . . . . . . . . add 15m-40
m = 5 . . . . . . . . . . . . . . . divide by 25
The height of the two balloons after 5 minutes will be 40+10·5 = 90 ft.
