Answer:
Multiplying a quantity by a conversion factor changes the units that measure a quantity but does not change the original amount of the quantity.
Step-by-step explanation:
There is no explanation
Answer:
Explicit form: 
Recursive form:
with
.
Step-by-step explanation:
The first term is 3 and we are dividing by 3 each time.
Another way to say we are dividing by 3 each time is to say we are multiplying by factors of 1/3.
If the first term is
and
is the common ratio then the geometric sequence in explicit form is:


The recursive form for a geometric sequence is
with
where
is the common ratio and
is the first term.
So the recursive form for our sequence is
with
.
The first one is km and the second is the second one is km
Answer:
2/13 or 0.15 , 1/4 and 5 /18 or 0.28
Step-by-step explanation:
20/26 ÷ 5 =?
10/13 ÷ 5 = 2/13 or 0.15
28/56 ÷ 2 =?
1/2 ÷ 2 = 1/4
75/90 ÷ 3 =?
5/6 ÷ 3 =5 /18 or 0.28
Even though its irregular its still an octagon. Therefore, it will still have 8 sides.
