Answer:
The sequence above is a geometric sequence
For an nth in a geometric sequence

where n is the number of terms
a is the first term
r is the common ratio
From the question
a = 45
r = 15 / 45
The explicit formula for the sequence is
U(n) = 45(1/3)^n-1
Hope this helps you
Answer:
5:15; 5 cups of juice and 15 cups of lemonade
Step-by-step explanation:
when simplified, the ratio is 1:3; so the first number multiplied by 3 equals the 2nd number
other answers: 6:18, 7:21, 8:24
This is a square, and so all the sides will be the same measurements. Note that you are given an area, so you'll have to root the total area to get a side.
√400 = 20
One side's measurements is 20 in
hope this helps
Answer: It should be 11
Step-by-step explanation:
11 + 3 = 14 14 is three more than 11 and when you add 5 you get 19
Looking at the choices i believe you need a g in your question. If it is 4g+2
Then you factor out at 2 to get 2(2g+1) choice a
If it 4+2g then you also factor out a 2 but this time get 2(2+g) choice b
Depending on what the question actually is those would be the answers
