Answer:
Step-by-step explanation:
Let us first closely examine the sequence for any mathematical correlation between the terms of sequence.
It is visualized that the series is progressing with addition of increasing even numbers starting with +6 ( +6, +8, +10, +12, +14, +16, +18 …) in the previous term to obtain next terms of the series. This logic continues for entire series.
The given series is:
1 ,7 ,15 ,25 ,37
Starting with first number of the series
1
1 + 6 = 7
7 + 8 = 15
15 + 10 = 25
25 + 12 = 37
37 + 14 = 51
51 + 16 = 67
67 + 18 = 85
The extended series is
1, 7, 15, 25, 37, 51, 67, 85
Part A).
If 100 fish all had the same weight, and they weighed
235 pounds when they were all on the scale at the
same time, then each fish weighed
235 / 100 pounds .
Part-B).
You can find that actual weight with your calculator.
235 / 100 = 2.35 pounds .
Part-C).
If there were only 10 fish but their total weight was still 235 pounds,
then each fish would have to weigh a lot more, to make up the same
weight with only 10 of them.
Now, each fish would have to weigh 235 / 10 pounds .
That number is 235/10 = 23.5 pounds.
If there were only 1/10 as many fish, then in order to add up to the
same total weight, each fish would have to be 10 times as heavy.
Answer:
840
Step-by-step explanation:
8×6×15=720
5×6×4=120
720+120=840
So, We Need To Write An Equation To Find This:
AD = lAl + lDl
So:
AD = l-7l + l8l
l-7l= 7.
AD = 7 + 8
7+8 = 15
AD = 15
So, AD = 15. This Means That The Answer Is B.
