Answer:
$13.50 typical tip
Step-by-step explanation:
So to find the percentage
multiply 0.15*90
You’ll get 13.5
The common difference of the sequence is -3 and the fifth term is 5
<h3>How to determine the common difference?</h3>
The sequence is given as:
17, 14, 11, 8....
The common difference is
d = T2 - T1
So, we have
d = 14 - 17
Evaluate
d = -3
Hence, the common difference of the sequence is -3
<h3>How to determine the
fifth term?</h3>
The fifth term is calculated as:
T5 = a + 4d
Where
a = T1 = 17
d = -3
So, we have:
T5 = 17 - 4 * 3
Evaluate
T5 = 5
Hence, the fifth term is 5
<h3>How to determine the
nth term?</h3>
The nth term is calculated as:
Tn = a + (n - 1)d
Hence, the nth term is Tn = a + (n - 1)d

Answer:
It could be 32:40.
Step-by-step explanation:
There is a constant ratio 4:5 with the ribbons in the boxes, so with a table you would go down multiplying both the numbers by the same to get the answer...
(4:5 x 2 = 8:10... x 3 = 12:15...x 4 = 16:20...etc.)
