Answer:
Kelvin wrote 60 the wrong way.
He has to write $30.65 - 60%, not 0.60.
Here is the final correct equation:
$30.65 - 60% = 12.26
Answer:
f(t) = 15 + 160 + 1
Step-by-step explanation:
it said that t= 4 and because the t is after the 40 you would times 40 by 4 to get 160. Then you add them all up and there you go you got your velocity and speed.
Answer:
The answer is B
Step-by-step explanation:
Answer:
The problem does not work.
Step-by-step explanation:
The plane with speed of 31 mph will cover 640 miles in
hours.
Now, it burns 5 gallons of gas every 3 minutes i.e. 0.05 hours.
So, it will burn in 20.64 hours
gallons.
Now, the helicopter with speed of 45 mph will cover 640 miles in
hours.
Now, it burns 7 gallons of gas every 5 minutes i.e. 0.083 hours.
So, it will burn in 14.22 hours
gallons.
But both of them starts with only 80 gallons of fuel.
Therefore, the problem does not work. (Answer)
