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:
You would use the formula: Rate = distance / time which equals 55
Since we are asked for the time it takes to reach 3/4 the destination.We just use 3/4 of the value of the distance.
55 = (3/4)(440) / t
t = 6 hours
So the answer would be "C"
The total costs that Nina would have to pay is the sum of the cost of insurance, utilities, and taxes.
C = $175 + $129 + $283 = $587
The highest house payment she could afford is then the difference between her budget and the costs,
P = $2,250 - $587 = $1663
Thus, the answer would be letter B. House B because all the rest of the monthly payment are way over her budget.

I was on a unit test so i couldn't look at the right answer but i believe it was A but i could be wrong
Step-by-step explanation:
Hi there!
Let's assume that one month is represented by the variable 'm', the amount of minutes you started with is 's', and minutes you spent is 'p'.
So, one month can be represented as 'm=s-p'.
The next month is a bit more tricky. This will incorporate 75 less minutes into the equation. 'm=s-75' can be used to represent this, as we assume that you didn't use any minutes in the first month, and that p=75 in this case.
