Answer:
180 teachers
Step-by-step explanation:
In this case, we know the value corresponding to 45% of female teachers which is 81, therefore, to find the total it would be:
% teachers #teachers
45 81
100 x
we apply the rule of three:
x = 100 * 81/45
x = 180
which means that there are a total of 180 teachers at Russell High
I know u are supposed to use formulas to do this...but it is just as easy to do it this way...that is, if u dont have many numbers...if u were looking for s20, we would have used formulas...lol
u will notice that in ur pattern, their is a difference of 5 between each number....this is an arithmetic sequence
start at 3
3 + 5 = 8
8 + 5 = 13
13 + 5 = 18
18 + 5 = 23
23 + 5 = 28
28 + 5 = 33
thats ur first 7 numbers...so just add them and u will have s7
s7 = 126
