16 miles because first you have to subtract your flat rate of $2 from $10, which will leave you left with $8. If it’s $0.50 per mile then divide that by the amount of money you have remaining after the flat rate deduction (8/0.50). After dividing you will find that you have enough money to travel 16 miles.
Answer:
600 minutes
Step-by-step explanation:
The total rate of the Pump is gotten first
15 + 20 = total rates of 35 gallon per hour .
rate = volume/ time.
Volume = rate * time
21,000 = 35 * t
t = 21,000/35
t = 600 minutes.
To check the volume each pump will pump out.
pump A 15 * 100 = 9000 gallons
Pump B 20 * 600 = 12000 gallons.
12,000+9,000= 21,000 which gives the total gallons of the swimming pool back
February is the only month that has a number of days divisible by 4 (to produce a integer).
That's because February has 28 days, and you can divide 28 by 4 to give you 7.
All the other months have 30 or 31, days, and 30 / 4 doesn't give you a whole number, and neither does 31.
To answer the second part of the question, no. During a leap year, February has 29 days. You can't divide 29 by 4 to give a whole number, hence it is then not true.
