Answer:
16
Step-by-step explanation:
b=16
Following the pattern, we can assume that each term adds by 1. So 15+1 = 16.
180 - 90 = 90.
x + 2x = 90
3x = 90
x = 30
One acute angle is 30, the other is 60.
A and B have the same perimeter
Answer:$15,679
Step-by-step explanation:
Mean is calculated as total sum of the amount divided by number of the amount.
From the given question, we add the amount together and divide by six:
Mean = $17,485 + $14,978+ $13,592 +$14,500 + $18,540 +$14,978/6
=$94,073/6
=$15,678.8
To the nearest dollar will be $15,679 since 0.8 is greater than 0.5, we round up.
I hope this helps.
Multiply 2 by 1/2 to get 1.
Multiply 1 by 2/3 to get 2/3.
Multiply 2/3 by 3/4 to get 6/12 = 1/2.
Multiply 1/2 by 4/5 to get 4/10 = 2/5.
Multiply 2/5 by 5/6 to get 10/30 = 1/3.
Multiply 1/3 by 6/7 to get 6/21 = 2/7. (I suspect there's a typo in the question.)
And so on, so that the <em>n</em>th term in the sequence is multiplied by <em>n</em>/(<em>n</em> + 1) to get the (<em>n</em> + 1)th term.
Recursively, the sequence is given by

We can solve this exactly by iterating:

and so on down to

or

and with lots of cancellation, we end up with
