10*3=30
30*3=90
90*3=270
270*3=810
or
10*3^1=30
10*3^2=90
10*3^3=270
10*3^4=810
the next two terms of this sequence are 270 and 810.
B percent of something (x)
means: b/100 * x
ex: (2)
20% of 120 = 20/100*120 = 24
ex: (4)
18 = 40 % of x
means: 40*x/100 = 18
x=45
and so on
hope that helps

<span>The answer to this question depends on the class size. However if we assume the class is sufficiently large then we can assume the 65% ratio stays relatively constant as students are selected. In this case we will treat selecting three students as independent events. Therefore we can multiply the probabilities. Finally, the probability of selecting three students that all like statistics more than algebra is (0.65)x(0.65)x(0.65) = 0.275.</span>

Step-by-step explanation:
You need to have the + or - signs in there if anyone is going to be able to help you do this problem.
Answer:
The answers are:
m = 9 and n = 15
Step-by-step explanation:
m/15 = n/25 = 12/20
m/15 = 12/20
m/15 = 3/5
5m = 45
m = 9
n/25 = 12/20
n/25 = 3/5
5n = 75
n = 15
