Volume of a cone is equal to pi*r^2*(h/3)
3.14*5^2*2/3 = 52.36 cubic cm.
Density = mass/volume
6 grams/ 52.36 cm^3= 0.1146
Round to 2 decimal places to get D.0.11 g/cm^3
Its saying that every 2 years the students decreases by 30 such as in 1990 the number of students in an large urban high school is 3490.In 1992 the number of students was 3460 and keep decreasing every 2 years 30 comes off.
The easiest way to move faster is to:
Years=The Number Of Students
2006=2200
2008=2170
2010=2140
2012=2110
2014=2080
2016=2050
But here is the tricky part the question said 2017 it an odd number so we have half of 30 because 30 comes of every 2 years but its the 1st year so it half of the 2 years and half of 30 students so this equals to:
2017=2035
20% because the 15-12=3 and then you cross multiply 3 and 100 and then you divide by 15. Which is 20.

The simple interest equation that represent the situation is A = t/5
<h3>What is simple interest?</h3>
Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest. For example, when a person takes a loan of 500 dollars, at a rate of 10 per annum for two years, the person's interest for two years will be S.I. on the borrowed money.
Principal(P) borrowed = $2
Rate(R) in percentage = 10
time in years = t
Simple interest(A) = P X R X t / 100
A = 2 X 10 X t/ 100
After reducing 20/100 to the lowest term
A = t/5
In conclusion the simple interest(A) = t/5
