in²
The surface area of a sphere is 400π in².
Answer: the answer is 432 per day so in 2 days she/he will have just enough
Step-by-step explanation:
Answer:
They both would cross each other again in the next 5 minutes
Step-by-step explanation:
The first thing to do here is to calculate the lowest common multiple of the average speed of both drivers.
That would be the lowest common multiple of 1.2 miles per minute and 1.8 miles per minute.
That would be 3.6 miles per minute.
Now to get the time at which they would cross each other again, we simply divide the total distance around the circular track by the lowest common multiple of their average speed.
That would be 18/3.6 = 5
This means they would cross each other again in the next 5 minutes
To solve this, you would need to determine the difference. To do this, you would simply subtract the discount from the total price.
$146.25 - $21 = $125.25
The final amount Jeremy will be billed is $125.25.
I hope this helps!
