Height: Inches Weight: P͟o͟u͟n͟d͟s͟
This analogy means that you can measure height in inches and weight in pounds.
So for each earring, she uses 3 blue, 1 metallic and 2 green..
so for 8 pairs.....thats 16 earrings....she would need :
16 * 3 = 48 blue
16 * 1 = 16 metallic
16 * 2 = 32 green
Answer:
I think the dad is 54 and the son is 20
In 6 years he would be 60 which is three times 20
The series
given is an example of arithmetic progression. The standard form of this series
is:
an = a + (<span><span>n − 1)</span> d</span>
Where,
<span>a = value of
the 1st term = 6b</span>
an = value
of the nth term
d = common
difference
n = how many
terms to add
<span>To calculate
for the common difference d, let us use the 1st term and 2nd
term. (any terms can be used as long as they are in succession)</span>
d = a2 – a1
d = 3b – 6b
d = -3b
<span>Substituting
all known value to the 1st equation:</span>
an = 6b
+ (<span><span>n − 1)</span> (-3b)</span>
an = 6b -3bn +3b
an = -3bn + 9b
Since there are only 5
terms therefore n = 1 to 5. The sigma notation is:
<span>D. sigma,
n=1, 5 above the sigma, -3bn+9b</span>
