Kelly traveled 50 miles with 20 gallons, 50/20 = 2.5 miles per gallon
Andy traveled 78.75 miles with 15 gallons, 78.75 / 15 = 5.25 miles per gallon
Rick traveled at 4.8 gallons per mile
Andy traveled furthest.
This is an area problem where the area of a circle is pi*r^2.
A quiche with a diameter of 12 has an area of pi*6^2 = 36pi
So if it can feed 6 people, then the serving size per person is 6pi per person.
A quiche with a diameter of 10 inches has an area of pi*5^2 = 25pi
If each person requires 6pi worth of quiche, then 25pi/6pi = 4 1/6 people.
So yes, it can serve 4 people.
Answer:
1. -9 2. 29
Step-by-step explanation:
For the negative numbers just subtract them and for the positive and negative numbers since the positive is greater -14 you add 29 to get away from zero and over to the positive side.
