Let x be the value of the third term.
Since it's a geometric sequence, then:
Third term/Second term = Fourth term/Third term
x/20 = 11.25/x
Cross multiplication:
x^2 = 225
x = 15
So since the ratio is constant, then it is
x/20 = 15/20 = 3/4
So the common ratio is 3/4 or 0.75.
Answer:
144 sq ft
Step-by-step explanation:
formula for finding triangle area: base x width x height; devided by 2
45/4 = 11.25
25 - 3 = 22
11.25 < 22
so, 45/4 < 25 - 3 or 11.25 < 22
Answer:
Two possible answers...
Step-by-step explanation:
You didn't specify whether it is am or pm, although it's more logical that it's pm, but I'll answer both anyway.
for 12pm:
when you're adding time, it's best to think in terms of twelve. if you add the first 12 hours, it completes the day and now you're in the tenth day of the month. add the other 10 hours and it is 10 am of the tenth day of the month.
for 12 am:
add just the same, except it's 10pm instead.
<span>7 - 9 = 2
9 - 11 = 2
You should see that the series just increases by +2
therefore you can figure out what the last four terms are and then add them up one of the last terms given is 21</span>
