Answer:
1 plane
Step-by-step explanation:
Let's suppose the number of planes waiting or on the runway " P "
the number of planes taking off per hour ' 
'
the time for waiting and the runway 
so:
P = x
= 18 airplanes per hour
we know that 1 min = 60s
36s = 36/60 = 0.6 min
Also, 3 min and 30 s = 3 + 30/60 = 3.5 min
Next to find the time for waiting and the runway
∴= 0.6 + 3.5 = 4.1 min/60 (converting into hour)
= 0.068 hour
P = 18x0.068 = 1.23
therefore, there is 1 plane either on the runway or waiting to take off
So, there is 1 plane either on the runway or waiting to take off

The answer to your question is 17/24 gallon
Step-by-step explanation:
Data
total volume = 1 gallon
She uses 3/8 gallon and 1/3 gallon
Process
1.- To find the answer, just sum up the water she used to water her roses and the volume she used to water her geraniums.
3/8 + 1/3 =
- Look for the Least common factor
8 x 3 = 24 LCF = 24
- Solve the fraction
3/8 + 1/3 = (9 + 8) / 24
= 17/24
2.- Conclusion
She used 17/24 gallon to water her flowers.
Answer:
3 * 10^3 in scientific notation.
3,000 in standard notation.
Step-by-step explanation:
We divide:
3.9 *10^5 / 1.3 * 10^2
= ( 3.9/1.3) * (10^5 / 10^2)
= 3 * 10(5-2)
= 3 * 10^3.
This equals 3 * 1,000 = 3000.
