146 minutes in total. One student =3 minutes. So then 42x3= 126. Class picture is 10x2=20. So then add both of them you get 146.
Answer:
1078
Step-by-step explanation:
first: multiply 980 by 0.10 to get 10% of 980
second: take that value (98) and add it to 980
then: you get 1078 after adding
When you regroup you are basically breaking down the problem.
You would do 60 + 40=?
Then you would do 4 + 3= ?
Your answer would come out to 107
Answer:
3rd option


Step-by-step explanation:
So we are given the following points:
(1,5)
(2,15)
(3,45)
(4,135)
This is a geometric sequence because there is a common ratio, 3. That is you can keep multiply 3 to a previous y-coordinate to get the next y-coordinate.
The formula for a geometric sequence is 
where
is the first term and r is the common ration.
So we have
.
If you want to know the fifth term, just plug in 5:

Simplifying:
