Answer:
$0.87
Step-by-step explanation:
2 quarts = 8 cups
$6.96 ÷ 8 = $0.87
The store paid $17.00
Solution: $24.00 (selling price) - $7.00 (difference of what the store paid) = $17.00
Let's assume that Kirby walks with a speed

for a time

, and that he runs with a speed

for a time

.
The total time available for Kirby to catch the train is:

and this must be equal to the sum of the two times t1 and t2:
The distance Kirby should cover is

and this should be equal to the sum of the distances covered by walking and by running:

So we have a system of 2 equations:


If we solve the system, we find:


So, Kirby needs to run at least for 8 minutes in order to catch the train.
Answer:
f=-x^2/2-2
Step-by-step explanation:
You first need to know the equation A=pi x r^2. The equation you need for this problem is pi (3.14) x 3^2
