Answer:
b-about 5 minutes
Step-by-step explanation:
For an object in uniform circular motion (=moving at constant velocity), the time taken to cover a certain distance is given by:
where
d is the distance covered
v is the speed of the object
In this problem we have:
d = 10 miles is the distance covered by both cars
Car A travels at a speed of
So the time it takes is
Car B travels at a speed of
So the time it takes is
So the difference in time is
So, the closest answer is
b-about 5 minutes
Answer:
o calculate the volume of a cone, start by finding the cone's radius, which is equal to half of its diameter. Next, plug the radius into the formula A = πr^2, where A is the area and r is the radius. Once you have the area, multiply it by the height of the cone.Step-by-step explanation:

The statements are true about the graphs of all nth degree polynomials are B and D.
B. It goes up and down at most a total of n times.
D. The number of x-intercepts is at most n.
Remark
The entire trip costs 485 dollars. She has a hundred, and you are looking for the number of weeks needed to save for the trip.
Step one
Set up the basic equation.
35w + 100 ≥ 485
Step two
solve
35w + 100 ≥ 485 Subtract 100 from both sides.
35W ≥ 485 - 100
35W ≥ 385 Divide by 35
W ≥ 385 / 35
W ≥ 11 weeks.
Since we don't have choices, we can't eliminate those that are wrong.
If I had to guess I would say it was something that looked like
35W + 100 ≥ 485
