Answer:
5 percent per annum
Step-by-step explanation:
interest rate:
interest: $1800
principal: $18000
duration: 2 years
1800/ 18000 * 100
result is 10%
Since interest is 10% in 2 years, 10% / 2
interest is 5% per year.
Answer:
It will take the police car 3.5 hours to travel a distance of 175 miles traveling at a rate of 50 miles/hour.
Step-by-step explanation:
If a car is traveling at a constant speed of 50 miles/hour and we wish to know how long it will take it to travel a distance of 175 miles, we will use this formula
d = r*t
Where d is the distance traveled in miles
r is the rate of speed in miles/ hour, and
t is the time in hours
d in this case is 175 miles and r is 50 miles/hour, plugging this in, we have
175 miles = (50 miles/hour) * t Divide both sides by 50 miles/hour
Our miles unit will cancel out, leaving us with
3.5 hours = t
Answer: 325
Step-by-step explanation:
Student tickets: x
Adult tickets: x + 71
Total: 579
x + x + 71 = 579
2x + 71 = 579
2x = 579 - 71
2x = 508
x = 508/2
x = 254
Adult tickets = x + 71 = 254 + 71 = 325
